SUMMARY
A London townhouse currently costs roughly £550,000–£700,000 at the accessible end, around £800,000–£1.5 million across much of the family-house market, and £2 million to £5 million-plus for the classic prime-central version.
The £641,000 London terraced-house average is useful as a statistical anchor, but geography overwhelms it quickly. The same official property category runs from about £488,000 in Bromley to roughly £2.4 million in Kensington and Chelsea.
£1 million is still a serious London house budget. It sits near the average terraced price in Wandsworth and Richmond and comfortably above the average in Haringey and Ealing, so buyers are not limited to the cheapest edges of the capital.
Above roughly £1.2 million, extra money increasingly buys address, scarcity and architectural quality rather than proportionally more usable space. That effect becomes much stronger in prime central London.
The current market is softer than the long-term London narrative suggests. Terraced prices are broadly flat to slightly down citywide, while several expensive boroughs have fallen much more sharply, giving buyers more room to negotiate on ordinary or compromised houses.
Stamp Duty changes the real budget fast. A standard main-home buyer pays £43,750 on a £1 million purchase and £153,750 on £2 million, while a non-resident additional-home buyer can pay £293,750 on that same £2 million property.
The upfront cash requirement is therefore much larger than the deposit alone. With a 25% deposit, a £1 million purchase needs about £294,000 before legal fees or work, while a £2 million purchase needs more than £650,000.
Financing is now one of the biggest constraints. At roughly 5.48% over 25 years, a 75% mortgage costs about £4,600 a month on a £1 million house and around £9,200 on a £2 million one.
Condition can erase an apparent bargain. A full refurbishment can absorb £100,000–£200,000 quickly, while structural, high-spec or heritage-sensitive work can push the bill toward £250,000, £400,000 or more.
The useful way to budget is purchase price first, then tax, financing and the condition of the actual building. In today's market, the strongest value is often in a good family house bought with negotiating room rather than in paying a large premium simply to cross into a famous prime address.

What does it cost to buy a townhouse in London?
Is there really an average price for a London townhouse?
A London townhouse currently costs roughly £500,000 at the accessible end of the market and several million pounds in prime central London, which makes the citywide average useful only as a starting point.
The closest clean official category is a terraced house. The latest UK House Price Index puts the average London terrace at about £641,000. That sounds like a reasonable answer until we look borough by borough.
According to the latest ONS and Land Registry figures, an average terraced house costs about £488,000 in Bromley, £545,000 in Greenwich, £698,000 in Ealing and £793,000 in Haringey. Richmond upon Thames is around £932,000, Wandsworth £956,000 and Islington £1.14 million. Kensington and Chelsea is already at roughly £2.4 million.
The gap between Bromley and Kensington and Chelsea is almost fivefold, even though both figures refer to the same official property category. Once we move from a normal Victorian terrace to a restored Georgian house in Chelsea, Belgravia or Notting Hill, prices can climb far beyond the borough average.
So we would use £641,000 to understand London's broad terraced-house market, but never to set a serious townhouse budget.

What counts as a townhouse in London?
A London townhouse usually means a multi-storey terraced house, but that label covers properties with completely different prices and buyers.
A three-bedroom Victorian terrace in Lewisham may be described as a townhouse. So can a five-storey Georgian house in Belgravia, a mews house in Chelsea or a recently built three-storey property in a gated development.
The physical similarities can be superficial. Age, width, floor area, garden size, architectural quality, conservation restrictions and street prestige change the economics dramatically.
A traditional Georgian townhouse in prime central London is also scarce in a way that a modern development townhouse is not. The buyer is partly paying for a piece of London's architectural stock that cannot be recreated on another street.
For the rest of this analysis, we therefore use townhouse broadly enough to include substantial terraced London houses, while separating ordinary family terraces from the prime-central historic product whenever price differences become important.

Can you still buy a London townhouse for under £700,000?
Yes, a London townhouse below £700,000 is still a realistic purchase today, although the search moves mainly toward outer and less expensive parts of the capital.
Official terraced-house averages remain below £700,000 in boroughs including Bromley, Greenwich, Lewisham and Ealing. Even within those boroughs, £700,000 can buy very different properties depending on station access, school catchments and whether the house has already been extended or renovated.
A buyer around £550,000 to £650,000 is more likely to find a conventional two- or three-storey Victorian terrace than the tall Georgian house people often picture when they hear “London townhouse.” But the latter belongs to a much more expensive market.
There is still plenty of London below the £1 million line. The idea that every decent house in the capital costs seven figures is exaggerated.
What has disappeared is the possibility of using £700,000 as an all-purpose budget across London. The same money that buys a full house in parts of south-east London may barely approach the price of a flat in some prime central neighborhoods.
Is £1 million enough for a good London townhouse?
Yes, £1 million is still a serious townhouse budget in London and gives buyers access to established family neighborhoods rather than just the cheapest edges of the city.
The clearest comparison comes from Wandsworth, Richmond and Haringey. Average terraced prices are currently around £956,000, £932,000 and £793,000 respectively. A £1 million buyer is therefore operating close to the middle of the terraced-house market in some of London's most established residential boroughs.
The quality of the £1 million house will vary sharply. In Haringey or Ealing, that budget can stretch to more floor area or a stronger period property. In Wandsworth or Richmond, buyers may have to choose between condition, street, station access and size.
The £1 million line becomes much less powerful once we move into prime central London. It generally will not buy the classic whole Georgian house in Chelsea, Kensington, Belgravia or the best streets of Notting Hill.
Still, £1 million should not be dismissed as a weak London budget. For someone who wants a genuine house rather than a trophy address, it opens a substantial part of the market.

How much more do you pay for an inner-London townhouse?
Moving into the stronger inner-London townhouse markets can add £400,000 to well over £1 million before the house becomes dramatically larger.
Look at the progression in official terraced-house prices. Greenwich is around £545,000, Ealing £698,000 and Haringey £793,000. Wandsworth reaches £956,000 and Islington £1.14 million. Kensington and Chelsea then jumps to about £2.4 million.
An average Islington terrace therefore costs roughly twice as much as one in Greenwich. Kensington and Chelsea is more than four times Greenwich.
Buyers are clearly paying for more than bedrooms. Shorter journeys, school catchments, intact period streets, restaurants, parks, neighborhood reputation and the limited supply of houses all get capitalized into the price.
Two London townhouses with similar floor plans can therefore be separated by £1 million. The building may explain some of the difference; the address often explains most of it.
How much does a real prime-central London townhouse cost?
A proper prime-central London townhouse is currently a several-million-pound purchase, with £3 million to £5 million a much more realistic range than the London-wide £641,000 terrace average.
Kensington and Chelsea makes the scale obvious. The latest ONS data put an average terraced property there at about £2.4 million, even after a 12.5% annual fall in that property category.
The borough average also mixes extremely expensive streets with less rare properties. Recent Land Registry-based sales data for Chelsea put the average sold terraced property above £4 million. Larger renovated houses on the strongest streets can move comfortably beyond £5 million, while exceptional properties enter an entirely different £10 million-plus market.
A buyer picturing stucco façades, four or five storeys, a prime west-London postcode and restored period interiors should therefore start the budget in the millions immediately.
The £641,000 London terrace average describes a large and real housing market. It just has very little to say about the price of a classic Chelsea or Belgravia townhouse.

Towers sold off plan to overseas buyers have been reselling below what the first owners paid for a decade now. Where asking prices sit furthest from what flats actually earn and resell for.
Are London townhouse prices still rising now?
No, London townhouse prices are broadly soft today, and some of the biggest declines are happening in the expensive boroughs where prime townhouses are concentrated.
The latest UK House Price Index puts London's overall home price at about £554,000, down 2.5% over the year. Terraced houses have held up much better, slipping only 0.3% to around £641,000, while flats fell 4.7%.
The borough split is more striking. Overall prices fell 5.2% in Wandsworth, 8.1% in Islington, 13.3% in Hammersmith and Fulham and 14.7% in Kensington and Chelsea. Within the terraced category, the declines were about 3.9% in Wandsworth, 7.1% in Islington and 12.5% in Kensington and Chelsea.
Prime-market evidence points in the same direction. Knight Frank's latest prime London data show prime-central prices still below their level a year earlier, although transaction activity has improved. Across London, transactions in the three months to July were 14% higher than a year earlier; prime central London itself was up 3%.
London houses have not entered a crash, but sellers no longer have the broad pricing power they enjoyed when cheap mortgages and the pandemic race for space were pushing buyers into houses.
| Market measure | Latest change | What we see |
|---|---|---|
| London all-property prices | -2.5% YoY | Broad market weakness |
| London terraced houses | -0.3% YoY | Houses holding up better than flats |
| Wandsworth all homes | -5.2% YoY | Clear repricing |
| Islington terraced houses | -7.1% YoY | Expensive inner-London houses under pressure |
| Kensington & Chelsea terraced houses | -12.5% YoY | Much sharper prime-area correction |
| London transactions, latest three months | +14% YoY | Buyers are returning despite softer prices |
How much Stamp Duty do you pay on a London townhouse?
Stamp Duty adds £43,750 to a £1 million London townhouse, £153,750 to a £2 million one and £393,750 to a £4 million one for a standard main-home buyer.
England's current residential SDLT bands charge nothing on the first £125,000, 2% from £125,000 to £250,000, 5% from £250,000 to £925,000, 10% from £925,000 to £1.5 million and 12% above £1.5 million.
The bill starts becoming genuinely large once the townhouse crosses seven figures. An £800,000 purchase generates £30,000 of SDLT. At £1.5 million, the bill reaches £93,750. At £3 million, it is £273,750.
Above £1.5 million, each extra £100,000 of purchase price creates another £12,000 of standard SDLT. That makes bidding an additional £300,000 on a prime townhouse a £336,000 decision before legal work, finance or renovation.
For expensive London houses, Stamp Duty belongs inside the budget from the beginning.
| Townhouse price | Standard SDLT | Effective SDLT rate | Price plus SDLT |
|---|---|---|---|
| £650,000 | £22,500 | 3.5% | £672,500 |
| £800,000 | £30,000 | 3.8% | £830,000 |
| £1.0m | £43,750 | 4.4% | £1.044m |
| £1.5m | £93,750 | 6.3% | £1.594m |
| £2.0m | £153,750 | 7.7% | £2.154m |
| £2.4m | £201,750 | 8.4% | £2.602m |
| £3.0m | £273,750 | 9.1% | £3.274m |
| £4.0m | £393,750 | 9.8% | £4.394m |

How much more does a London townhouse cost for a second-home or overseas buyer?
A £2 million London townhouse can carry £293,750 of Stamp Duty for a non-UK resident who is also buying an additional home, almost twice the £153,750 paid by a standard main-home buyer.
The additional-property surcharge is currently five percentage points on top of the normal residential rates. HMRC looks at residential property ownership worldwide, so owning a home outside Britain can still bring the higher rates into play.
Non-UK residents can face another two-percentage-point surcharge. The two charges can stack.
At £1 million, standard SDLT is £43,750. An additional-home buyer pays £93,750. A non-resident buying an additional property pays £113,750.
At £4 million, those numbers become £393,750, £593,750 and £673,750.
The £280,000 gap between the standard and combined-surcharge tax bills on that £4 million house exists before the buyer changes a single thing about the property.
For international buyers, the tax status of the purchaser can therefore change the acquisition cost almost as much as moving to a more expensive street.
| Purchase price | Main home | Additional home | Non-resident main home | Additional + non-resident |
|---|---|---|---|---|
| £800,000 | £30,000 | £70,000 | £46,000 | £86,000 |
| £1.0m | £43,750 | £93,750 | £63,750 | £113,750 |
| £1.5m | £93,750 | £168,750 | £123,750 | £198,750 |
| £2.0m | £153,750 | £253,750 | £193,750 | £293,750 |
| £3.0m | £273,750 | £423,750 | £333,750 | £483,750 |
| £4.0m | £393,750 | £593,750 | £473,750 | £673,750 |
How much cash do you need upfront for a London townhouse?
Buying a £1 million London townhouse with a 25% deposit requires roughly £294,000 before legal fees, surveys or renovation, because the buyer needs £250,000 for the deposit and another £43,750 for Stamp Duty.
The same calculation becomes much heavier higher up the market.
A £1.5 million townhouse needs a £375,000 deposit at 75% loan-to-value. Add £93,750 of standard SDLT and the cash requirement is already £468,750.
For a £2 million house, the deposit is £500,000 and SDLT £153,750. The buyer needs more than £650,000 before paying the solicitor, commissioning a survey or touching the property.
At £3 million, a 25% deposit plus standard SDLT comes to just over £1.02 million.
Someone with £500,000 available therefore cannot automatically treat £2 million as a comfortable purchase ceiling. Taxes absorb a large part of the cash that might otherwise have strengthened the deposit.

What does the mortgage on a London townhouse cost today?
Financing 75% of a £1 million London townhouse currently works out at roughly £4,600 a month over 25 years using the latest average two-year fixed rate for a 75% LTV mortgage.
Moneyfacts currently puts the average two-year fixed rate at about 5.5% for borrowers at 75% loan-to-value. The broader two-year fixed market has recently moved above 5.6%, after rising borrowing costs pushed lenders to reprice deals.
Using 5.48% as a realistic benchmark rather than pretending every buyer gets the cheapest advertised mortgage, a £600,000 loan on an £800,000 townhouse costs roughly £3,680 a month over 25 years.
A £750,000 mortgage on a £1 million house comes to about £4,600. Borrowing £1.125 million on a £1.5 million townhouse pushes the payment close to £6,900 a month.
At £2 million, a 75% mortgage means borrowing £1.5 million and paying around £9,200 a month. A £3 million purchase financed the same way gets close to £13,800 monthly.
These numbers also show why expensive London property has been struggling lately. A buyer can negotiate 5% off a £1.5 million townhouse and save £75,000, yet the cost of financing still dominates the monthly affordability calculation.
| House price | 25% deposit | 75% mortgage | Approx. monthly payment at 5.48%, 25 years |
|---|---|---|---|
| £650,000 | £162,500 | £487,500 | £2,990 |
| £800,000 | £200,000 | £600,000 | £3,680 |
| £1.0m | £250,000 | £750,000 | £4,600 |
| £1.2m | £300,000 | £900,000 | £5,520 |
| £1.5m | £375,000 | £1.125m | £6,900 |
| £2.0m | £500,000 | £1.500m | £9,190 |
| £3.0m | £750,000 | £2.250m | £13,790 |
How much can surveys, legal work and renovation add to a London townhouse?
An old London townhouse can add well over £100,000 to the headline purchase price once we include proper due diligence and refurbishment, and a serious renovation can run into several hundred thousand pounds.
The solicitor and survey are the smaller part. Conveyancing, searches, registration and a detailed building survey will normally cost a few thousand pounds. On a century-old house, paying for a thorough survey is hard to argue against.
Renovation is where the numbers become meaningful. A tired London terrace needing a full internal overhaul can consume roughly £100,000 to £200,000 surprisingly quickly once kitchens, bathrooms, wiring, plumbing, heating, plasterwork, flooring and decoration are combined.
Structural changes push the figure higher. Extensions, major roof work, basement alterations, bespoke joinery and high-end finishes can move a townhouse renovation toward £250,000, £400,000 or more.
Historic prime houses can be much harder again. Listed-building restrictions, conservation requirements, specialist windows, stonework, old roofs and complex layouts can turn apparently straightforward work into an expensive project.
A tired £1.5 million townhouse can therefore end up costing more than a renovated £1.75 million alternative. The discount only counts after we subtract the actual cost of making the cheaper property usable.
| Project | Rough London budget | What usually drives the cost |
|---|---|---|
| Legal work, searches and survey | Several thousand pounds | Property value, complexity, survey depth |
| Light refurbishment | £50k–£100k | Decoration, floors, modest kitchen/bath work |
| Full conventional refurbishment | £100k–£200k+ | Services, kitchen, bathrooms, plastering |
| Structural/high-spec renovation | £200k–£400k+ | Extensions, structure, bespoke finishes |
| Complex prime or heritage project | £400k+ possible | Listed fabric, basement work, specialist trades |
How to spot hidden problems when you visit a flat in London
Damp on a lower ground floor, cladding on anything tall, and a lift and a roof that a future bill will pay for. What to look at, and what each thing is telling you about the years ahead.
Does a London townhouse stay cheap to own after you buy it?
No, an expensive London townhouse can still cost tens of thousands of pounds over time through maintenance, insurance, local taxes and private estate charges even when the property is freehold.
Traditional terraces often avoid the service charges associated with apartment blocks, but the owner takes responsibility for the whole building. Roofs, façades, sash windows, boilers, drainage and external walls eventually need work, and large period houses have a lot of each.
Newer freehold townhouses can also carry estate-management charges where roads, landscaping, gates or shared spaces remain privately managed. Freehold ownership therefore does not automatically mean zero communal charges.
There is another cost approaching at the top of the market. From 2028, England plans to introduce the High Value Council Tax Surcharge for homes valued at £2 million or more. The proposed annual charge is £2,500 from £2 million to £2.5 million, £3,500 from £2.5 million to £3.5 million, £5,000 from £3.5 million to £5 million and £7,500 above £5 million.
Those sums are small beside the purchase price, but they reinforce a broader point: the running cost curve becomes steeper once a London townhouse moves into prime territory.
Is now a good time to negotiate on a London townhouse?
Yes, buyers currently have real negotiating room in London, especially on expensive houses that have been sitting on the market or need substantial work.
The market backdrop is much weaker than the stereotype of permanently rising London property suggests. As seen above, official data show London prices down overall, while expensive boroughs such as Wandsworth, Islington, Hammersmith and Fulham, and Kensington and Chelsea have recorded much larger annual declines.
The freshest national evidence has weakened again. Lloyds' latest index showed UK house prices falling year on year for the first time in almost three years, with London among the weakest regions. At the same time, average fixed mortgage rates have climbed back above 5.6%, which reduces what leveraged buyers can afford.
Prime London is showing more transactions, so this is not widespread distress. Knight Frank recorded a 14% annual rise in London transactions across its latest three-month window even while prime prices remained down.
For buyers, that is a useful environment. Demand still exists for good houses, but an owner with an ordinary property and an ambitious asking price can no longer assume that another buyer will immediately pay it.
The strongest bargaining targets are stale listings, homes requiring major renovation and properties priced from an older market peak. Rare houses on exceptional streets can still attract competition.

Does spending £2 million get you twice the townhouse you get for £1 million?
No, doubling a London townhouse budget from £1 million to £2 million usually buys a much stronger address and better house, but nowhere near twice the usable space.
Around £1 million already intersects with the average terraced market in Wandsworth and Richmond and sits comfortably above the average in Haringey and Ealing. Buyers at that level can already obtain substantial family houses.
The next million increasingly pays for scarcity. It can move the search toward better streets in Wandsworth, Fulham, Islington, Highbury or parts of Notting Hill, while also improving width, garden, condition and architectural quality.
Once the search reaches £3 million and above, the relationship between price and physical house becomes even looser. A move of a few streets can add hundreds of thousands of pounds if it crosses into a famous garden square, conservation area or school catchment.
London townhouse prices therefore behave much more like a location market than a simple price-per-bedroom market. Around the middle of London, extra money buys a mixture of house and address. In prime central London, the address can dominate.
What should you budget for a London townhouse now?
A practical London townhouse budget today is around £550,000–£700,000 at the accessible end, £800,000–£1.2 million for a strong family-house search, £1.2 million–£2 million for better inner-London stock and several million pounds for prime central London.
The useful number is the amount needed after purchase taxes and immediate work.
A £650,000 main-home purchase becomes £672,500 after standard SDLT. Allow for legal work and a survey and we are around £675,000 before refurbishment.
At £1 million, the purchase is already about £1.044 million after SDLT. Routine buying costs take the figure slightly higher, while a £100,000 refurbishment pushes the real project toward £1.15 million.
A £1.5 million townhouse costs £1.594 million after SDLT. Add a substantial £150,000 renovation and the total capital commitment approaches £1.75 million.
At £2.4 million, roughly the current Kensington and Chelsea terraced-house average, standard SDLT takes acquisition cost to about £2.60 million before professional costs or work.
A £4 million prime townhouse reaches approximately £4.39 million after standard SDLT alone. A serious £300,000 refurbishment brings the project close to £4.7 million.
Better to think about London townhouse prices as purchase price first, then tax, then financing, then the condition of the actual building.
| Type of townhouse | Typical price range | Standard SDLT at representative price | Realistic interpretation |
|---|---|---|---|
| Accessible outer-London terrace | £550k–£700k | £22.5k at £650k | London house ownership is still possible below £1m |
| Strong family townhouse | £800k–£1.2m | £43.75k at £1m | Large part of established London opens up |
| Better inner-London townhouse | £1.2m–£2m | £93.75k at £1.5m | Location starts absorbing more of the budget |
| High-end inner London | £2m–£3m | £201.75k at £2.4m | Tax and scarcity become major costs |
| Prime-central townhouse | £3m–£5m+ | £393.75k at £4m | Multi-million-pound asset market |

What does it really cost to buy a townhouse in London?
A London townhouse currently costs about £500,000–£700,000 at the lower end, around £800,000–£1.5 million for the broad family-house market and £2 million to £5 million-plus for the classic prime London version.
The citywide £641,000 terraced-house average is technically correct and practically incomplete. Greenwich is around £545,000, Wandsworth £956,000, Islington £1.14 million and Kensington and Chelsea about £2.4 million. Actual terraced sales in Chelsea can average above £4 million.
Then come the costs that do not appear on the estate-agent listing. A £1 million main-home buyer pays £43,750 of Stamp Duty; a £2 million buyer pays £153,750. Additional-property and overseas surcharges can take the £2 million tax bill as high as £293,750. Mortgage financing at 75% LTV is currently around the mid-5% range, meaning roughly £4,600 a month on a £750,000, 25-year loan. A tired period house can easily demand another £100,000 to £200,000 of work.
Our clearest conclusion is that £1 million still buys a proper London townhouse. Around £1.5 million gives a buyer much stronger access to desirable inner-London family houses. The archetypal Chelsea, Kensington, Belgravia or prime Notting Hill townhouse belongs to another price bracket entirely, where several million pounds is normal.
The current market is also better for buyers than the long-term London story might suggest. Prices are soft, mortgage costs are biting and some expensive boroughs have fallen sharply. That gives buyers room to negotiate, particularly when a house is compromised or overpriced.
For a realistic budget, we would therefore add roughly 5% to 10% to many seven-figure asking prices just to cover acquisition costs, then treat renovation separately. For second-home and non-resident buyers, or for an old house needing serious work, the gap between the advertised price and the money actually committed can become much larger.
OUR METHODOLOGY
The cost of a London townhouse looks like a simple price question, but a single citywide average does not survive contact with London's geography. We therefore broke the question into the dimensions that materially change the answer: property type, borough, prime versus mainstream stock, purchase tax, financing, condition and the current balance between buyers and sellers.
Because “townhouse” is not a standalone category in official housing statistics, we used terraced houses as the cleanest statistical anchor. We then separated ordinary family terraces from scarcer historic and prime-central houses whenever the market evidence showed that the two were behaving very differently.
For broad and borough-level pricing, we prioritized the UK House Price Index, ONS local housing-price data and HM Land Registry transaction records. Those sources give the cleanest base for comparing London as a whole with boroughs such as Bromley, Greenwich, Ealing, Haringey, Richmond upon Thames, Wandsworth, Islington and Kensington and Chelsea.
Prime central London needed a separate layer of evidence because borough averages can hide the economics of individual streets and rare period houses. We used recent Land Registry-based sales evidence and Knight Frank's prime-market research to judge the higher end of the townhouse market and current transaction conditions.
The budget bands in the article are analytical ranges rather than official categories. We built them by combining current price evidence with what those levels realistically reach across London, then tested the headline purchase price against the costs that a buyer actually has to fund.
Stamp Duty calculations use the current HMRC residential SDLT bands, including the higher rates for additional properties and the separate non-UK resident surcharge where relevant. This keeps the tax examples reproducible rather than relying on secondary summaries.
For mortgage examples, we used 75% loan-to-value and a 25-year repayment term, with 5.48% as the representative two-year fixed benchmark cited in the analysis. Moneyfacts provides the current market-rate comparison, while the Bank of England's quoted household interest-rate series gives an independent financing reference.
Renovation and due-diligence costs are treated as project ranges, not as precise citywide averages. RICS guidance informs the survey side, while Historic England is particularly relevant for older, listed and conservation-sensitive houses where apparently ordinary work can become much more involved.
We did not use one annual price change to decide whether London was a good or bad market for buyers. We compared citywide house-price direction, borough-level declines, prime-market activity, transaction volumes and mortgage conditions, then used those pieces together to judge how much negotiating room exists today.
Key sources include the UK House Price Index for England, ONS local housing-price data for Kensington and Chelsea, HM Land Registry Price Paid Data, HMRC's residential Stamp Duty rates, HMRC guidance on additional-property rates, HMRC guidance for non-UK resident buyers, the Bank of England's quoted household mortgage-rate series, Moneyfacts fixed-rate mortgage data, the Halifax House Price Index, Knight Frank's 2026 prime residential research, RICS Home Survey guidance, Historic England guidance for older buildings, and HM Treasury's High Value Council Tax Surcharge guidance.
The areas and new build projects in London that are most overpriced
Towers sold off plan to overseas buyers have been reselling below what the first owners paid for a decade now. Where asking prices sit furthest from what flats actually earn and resell for.
