SUMMARY
Yes. Shared ownership is still worth it in London when the deposit or mortgage needed for a conventional purchase is the one thing keeping an otherwise financially stable household in expensive private rent.
The deposit advantage is still enormous. Using a £431,000 London flat as a benchmark, a 25% shared ownership purchase with a 5% deposit on the share needs roughly £5,400 upfront, compared with about £43,100 for a 10% deposit on the whole property.
The monthly maths can still work too. A carefully priced shared ownership home can cost several hundred pounds less each month than private renting, but the service charge often decides whether that saving is real or mostly disappears.
The cheap entrance is also what makes the tenure easy to misread. Shared ownership rent rises over time, service charges can jump, mortgage costs eventually reset, and none of those expenses automatically fall just because the flat itself has lost value.
Service charges are the biggest thing we would worry about in London. A buyer can own only 25% of the equity and still be responsible for the lease-defined service charge, so a low advertised deposit can sit on top of a very expensive building.
The newer shared ownership model is materially better than many older leases. Lower initial shares, smaller staircasing increments, 990-year minimum leases, a four-week nomination period and the 10-year initial repair period all remove some of the scheme’s roughest edges.
Full staircasing should still be treated as an option, not the expected end point. The practical constraint is rarely the percentage allowed by the lease; it is finding enough cash and borrowing capacity to buy another slice of a London property while every other housing cost is rising.
Falling London flat prices cut both ways. They make future staircasing cheaper, but they also reduce the value of the equity already owned and can make a short-horizon resale especially painful.
A good resale shared ownership flat can be better value than a new one because the buyer can inspect real service-charge history, reserve funds and major works rather than relying mainly on forecasts. The trade-off is that older leases can have worse repair, staircasing and resale terms.
The best fit is a stable-income buyer with a small deposit, a long holding period and a boringly low service charge. If another year of saving would open the door to an acceptable conventional flat, shared ownership becomes much harder to justify.

Is shared ownership still solving London’s homeownership problem?
Shared ownership still solves one very specific London problem very well: getting through the deposit and mortgage barrier when buying a whole property is simply out of reach.
That barrier remains huge. According to the latest UK House Price Index, the average London property costs about £554,000, an average flat or maisonette about £431,000, and the average home bought by a first-time buyer about £472,000. London prices have softened lately, but they have not fallen anywhere near enough to make ordinary homeownership accessible to most middle-income renters.
Shared ownership lets an eligible buyer purchase only part of the property and pay rent on the rest. Under the current scheme, some homes can be bought from a 10% initial share, with a deposit usually equal to 5% to 10% of the share being purchased. London households generally need income of £90,000 or less and must be unable to afford a suitable home outright.
So the scheme still has a purpose. What is harder to defend is the idea that shared ownership automatically provides cheap homeownership over the long run. Mortgage payments, rent on the unsold share, service charges, repairs and eventually selling the property all need to work together. For some London homes they do. For others, the cheap deposit disguises an expensive property.
Does shared ownership still slash the deposit needed to buy in London?
Yes. The deposit saving is still shared ownership’s strongest advantage in London, and the difference can easily run into tens of thousands of pounds.
Take the current £431,000 average London flat price as a simple benchmark. Someone buying the whole property with a 10% deposit needs about £43,100 before legal fees and other costs.
If the same property were available through shared ownership and the buyer purchased 25%, the share would cost £107,750. With a 5% deposit on that share, the buyer would need only about £5,400.
That is an 87.5% reduction in the initial deposit compared with putting down 10% on the whole flat. At a 10% ownership share, the illustrative deposit falls to barely £2,000.
Those examples do not mean the typical shared ownership property costs exactly £431,000. They show why the structure remains so powerful in London. A renter who can save £5,000 may be several years away from accumulating £40,000 or £50,000, especially while paying London rent every month.
| Illustrative purchase | Full ownership | 50% share | 25% share | 10% share |
|---|---|---|---|---|
| Full property value | £431,000 | £431,000 | £431,000 | £431,000 |
| Share purchased | £431,000 | £215,500 | £107,750 | £43,100 |
| Deposit assumption | 10% | 5% of share | 5% of share | 5% of share |
| Cash deposit | £43,100 | £10,775 | £5,388 | £2,155 |
| Saving versus full-purchase deposit | — | £32,325 | £37,712 | £40,945 |

Is shared ownership actually cheaper than renting in London now?
Often, yes. A well-priced London shared ownership flat can still cost materially less each month than renting a similar home privately, but service charges decide how big that advantage really is.
The latest Office for National Statistics data put average private rent in London at £2,317 a month. London remains by far England’s most expensive rental region, and rents were still 3% higher than a year earlier.
Consider our £431,000 flat again. A buyer purchasing 25% would own £107,750 of the property. With a 5% deposit and a 30-year mortgage, using the Bank of England’s latest 4.45% effective rate on newly drawn mortgages as an illustration, the mortgage payment comes to roughly £516 a month.
Government guidance says initial shared ownership rent is commonly around 2.75% of the landlord’s share each year. Renting the remaining 75% of this property would therefore cost roughly £741 a month. Mortgage and rent together come to about £1,257.
A £250 monthly service charge pushes that to roughly £1,507. A £500 charge takes it to £1,757.
Even the second figure remains below London’s £2,317 average private rent, although this is not a perfect like-for-like comparison because average rent covers different property types and locations. The useful part is the order of magnitude: shared ownership can still create several hundred pounds of monthly breathing room.
| Illustrative 25% purchase | Monthly housing cost |
|---|---|
| Mortgage on owned share | ~£516 |
| Rent on unsold 75% | ~£741 |
| Mortgage + shared ownership rent | ~£1,257 |
| With £250 service charge | ~£1,507 |
| With £500 service charge | ~£1,757 |
| Current average London private rent | £2,317 |
Is shared ownership cheaper than buying a London flat outright?
For monthly cash flow, shared ownership is usually much cheaper than buying the same London flat outright. Over many years, the advantage becomes less clear because part of the shared owner’s payment is rent rather than equity.
At today’s mortgage rates, financing 90% of a £431,000 flat over 30 years would produce a monthly mortgage bill of roughly £1,950. Our illustrative 25% shared ownership buyer pays about £1,257 in mortgage and rent before service charges.
The outright buyer is paying much more each month, but a larger part of that money is buying the property. Every principal repayment increases the buyer’s equity. Rent paid to a housing association does not.
That changes who should care about shared ownership. Someone who cannot borrow enough to buy a suitable London home outright gains a lot from reducing the mortgage size. Someone already capable of buying a reasonable property conventionally has much less to gain from keeping a landlord involved and paying rent on an unsold share for years.
The current London market strengthens that argument slightly. Buyers are no longer chasing rapidly rising flat prices: the latest Land Registry figures show London flats down 4.7% over twelve months. Someone who is close to buying normally has more reason today to compare conventional resale flats carefully rather than assuming shared ownership is the only way onto the ladder.
Everything a foreign buyer should know before buying in London
The pack also covers what a short lease will cost you to fix, and why an accepted offer here means nothing until exchange.
Will shared ownership rent keep getting more expensive?
Yes. London shared ownership buyers should assume that rent on the unsold share will rise over time, even during periods when the property itself falls in value.
The exact formula depends on the lease. Many older leases use RPI plus 0.5%, while newer shared ownership leases can use CPI plus 1%. Government guidance also makes clear that rent is generally reviewed annually and does not normally fall.
That creates a slightly awkward setup. London flat values can decline while the rent payable to the housing provider keeps moving upward.
A £750 monthly shared ownership rent rising by 4% a year becomes about £912 after five years. At 5% annual increases, it reaches roughly £957. The increase is manageable for some households, but it becomes much more important when service charges and mortgage costs are also rising.
For that reason, we would never judge a shared ownership property from its first-year monthly payment alone. The useful question is what the bill looks like after five years under a realistic rent-increase assumption.
| Starting monthly rent | After 5 years at 2% | At 3% | At 4% | At 5% |
|---|---|---|---|---|
| £500 | £552 | £580 | £608 | £638 |
| £750 | £828 | £869 | £912 | £957 |
| £1,000 | £1,104 | £1,159 | £1,217 | £1,276 |
Are service charges now the biggest risk with London shared ownership?
For many London flats, yes. Service charges can wreck an otherwise sensible shared ownership purchase faster than almost any other cost.
The uncomfortable part is that owning 25% of a flat does not mean paying 25% of the relevant service charge. Shared owners can be responsible for the charges specified in the lease even while the housing provider still owns most of the equity.
Government itself has now acknowledged the problem. In a parliamentary answer this summer, the housing ministry said service-charge affordability and other ongoing housing costs can make it harder for shared owners to staircase. It also pointed to new expectations for landlords around long-term affordability, cost transparency, non-profit fees and letting residents opt out of optional services.
That is quite an admission. Staircasing is supposed to be the mechanism through which partial owners gradually buy more of their homes. If the running costs of the scheme prevent households from saving enough to buy another share, one of the central promises of shared ownership stops working.
Recent Housing Ombudsman cases have also involved providers such as Notting Hill Genesis and Metropolitan Thames Valley Housing over poor handling or explanation of service charges. Disputes about whether the level of a service charge itself is reasonable can be even harder because they may have to go through the property tribunal rather than the Ombudsman.
A £150 service charge can leave the economics of shared ownership looking very good. At £500, £600 or more, the same flat becomes a completely different proposition. We would therefore check several years of actual service-charge accounts, planned major works and the building’s reserve fund before paying much attention to the advertised deposit.

Have newer shared ownership leases fixed the repair problem?
Newer shared ownership leases are clearly better on repairs, but London buyers still need to check exactly which lease model they are getting.
Government guidance for the latest shared ownership model includes a 10-year initial repair period on qualifying homes. During that period, landlords cover certain essential external and structural repairs. Buyers can also normally claim up to £500 a year towards eligible internal repairs, with a limited amount capable of rolling into the following year.
That is a meaningful improvement. Under many older arrangements, shared owners could be responsible for repairs despite owning only a fraction of the property.
The newer model also comes with other improvements: some homes can start at a 10% share instead of 25%, standard staircasing can begin at 5%, qualifying buyers can purchase another 1% each year for up to 15 years, and new leases under the model have a minimum 990-year term.
The catch is the word “newer.” A shared ownership resale can still carry an older lease with much less generous terms. Even under the new model, service charges continue during the repair period, and after the protection expires the owner takes on more responsibility.
So the reform has removed some genuinely bad features. It has not made the lease irrelevant.
Do London shared owners actually reach 100% ownership?
Not often enough for us to treat full ownership as the normal outcome. London buyers should see staircasing as an option rather than an automatic path to owning the whole property.
Evidence examined by Parliament found estimates suggesting that only around 3% of shared owners nationally staircase to 100% in a typical year. One industry estimate put London much higher, at 15.3%, but Parliament also noted that some owners staircase fully immediately before selling.
That distinction changes the story. Buying the remaining share on the way out technically counts as reaching 100%, yet the household has not spent years progressing from partial to full ownership.
Newer leases make small increases easier. Qualifying owners can buy an additional 1% each year for the first 15 years, while standard staircasing on newer homes can begin from 5%. Older leases commonly require at least 10%, and some require 25%.
Larger transactions also bring costs. Government guidance says a RICS valuation is normally required for standard staircasing, landlords may charge administration fees of roughly £150 to £500, and legal costs can apply.
For a London household buying a £400,000 property, another 5% still means finding £20,000 at the property’s current valuation before transaction costs. The percentage sounds small; the cash amount often is not.
| Staircasing feature | Newer shared ownership model | Many older leases | Practical effect |
|---|---|---|---|
| Initial share | From 10% on some homes | Often 25%+ | Newer homes are easier to enter |
| Gradual purchase | 1% yearly may be available | Usually unavailable | Small increases are possible |
| Standard minimum | Often 5% | Commonly 10% or more | Old leases require larger jumps |
| RICS valuation | Usually for standard staircasing | Usually required | Adds transaction cost |
| Maximum ownership | Usually 100% | Usually 100% | Affordability remains the real obstacle |

Do falling London flat prices help shared ownership buyers?
Falling London flat prices help people who want to buy more shares, but they hurt owners who need to sell. Shared ownership buyers are getting both sides of that equation.
London flats and maisonettes have fallen about 4.7% over the latest twelve-month period according to the Land Registry. That makes additional equity cheaper than it would have been at last year’s prices.
Imagine a shared owner with 25% of a £400,000 flat. Another 25% costs £100,000 at that valuation. If the home rises to £480,000, the same extra share costs £120,000. If it falls to £360,000, the additional share costs £90,000.
That £30,000 difference between the rising and falling scenarios is substantial for someone planning to staircase.
Existing equity moves the same way, though. The original 25% share worth £100,000 becomes worth £90,000 after a 10% property decline. If the buyer started with only a £5,000 deposit and financed most of the share, a relatively modest fall can wipe out the original cash equity on paper.
Shared ownership does reduce the absolute size of the exposure because the buyer owns only part of the property. It does not protect the owned share from falling prices.
For someone planning to stay and staircase, today’s weaker London flat market can actually be useful. For someone forced to sell after a short holding period, it can be painful.
Is selling a shared ownership flat harder in London?
Yes. Selling a shared ownership flat usually involves more friction than selling an ordinary London flat, and that matters a lot if the owner may need to move quickly.
A shared owner who has not reached 100% normally has to notify the housing provider first. Depending on the lease, the provider gets a nomination period in which it can find another eligible shared ownership buyer.
Newer leases have improved this. Government guidance for the latest model reduces the provider’s nomination period to four weeks, compared with eight weeks on many earlier leases and sometimes twelve weeks on older ones.
The seller still has other constraints. A RICS valuation generally sets the market value, and the incoming buyer must satisfy shared ownership eligibility and affordability tests. The pool of potential purchasers is therefore narrower than for an ordinary private sale.
In a strong market, that extra process may barely matter. In a weak flat market, every additional restriction becomes more noticeable because sellers are already competing for a smaller number of buyers.
We would be wary of shared ownership for anyone who expects to move again in two or three years. The scheme makes much more sense when the household can stay long enough for the low initial deposit and equity building to outweigh the inconvenience of eventually leaving.

Is a resale shared ownership flat better value than a new one?
A good resale shared ownership flat can be the smarter buy in London today because buyers can see the building’s real costs rather than relying mainly on forecasts.
With a resale, we can inspect several years of service charges, previous increases, reserve-fund contributions, major works and how the housing provider actually manages the building. That information is extremely valuable in a tenure where ongoing costs can decide whether the purchase works.
The weak London flat market also gives resale buyers more room to compare prices. The latest Land Registry figures show flats underperforming houses quite sharply, so there is less reason to accept an obvious new-build premium simply to access shared ownership.
Older stock comes with its own problem: the lease can be worse. The property may have a shorter lease, larger minimum staircasing increments and no 10-year initial repair period.
That means “new versus resale” is the wrong shortcut. We would rather buy a well-priced resale with a clean service-charge record and sensible lease than an expensive new build with costly amenities. But a badly structured old lease can easily outweigh the discount.
The documents tell us more than the age of the kitchen. Lease length, rent formula, current service charge, past increases, reserve fund, planned works and staircasing rules are the numbers worth comparing.
Is shared ownership really designed for low-income Londoners?
No. Shared ownership in London mostly serves households caught between social housing and conventional homeownership, including plenty of people earning what would normally be considered solid salaries.
The official London income ceiling is £90,000 per household. Compare that with an average first-time-buyer property price of roughly £472,000. Even a household earning the full £90,000 and borrowing 4.5 times income would reach about £405,000 before lenders account for existing debts, living costs and deposit requirements.
City Hall data on shared ownership buyers make the target market even clearer. In the dataset it analysed, fewer than 1% of London shared ownership households earned below £30,000. Around 25% earned £30,000 to £49,999, 44% earned £50,000 to £67,000 and 30% earned more than £67,000.
Shared ownership has therefore become particularly relevant to London’s squeezed middle: households capable of paying substantial housing costs but still unable to finance a normal purchase.
| Household income | Share of London shared ownership buyers in City Hall data |
|---|---|
| Under £30,000 | <1% |
| £30,000–£49,999 | 25% |
| £50,000–£67,000 | 44% |
| Above £67,000 | 30% |

Is shared ownership better than continuing to rent in London?
For someone planning to stay in the same home for years, shared ownership can beat private renting quite comfortably. For someone who values mobility or can access London Living Rent, the answer becomes much less obvious.
Private renters in London are currently paying £2,317 a month on average according to the ONS. That money buys flexibility: renters do not take property-price risk, do not need to staircase, do not have to find an eligible shared ownership purchaser when they leave and are less exposed to major building costs.
Shared owners trade away some of that flexibility. In return, part of their monthly housing payment services a mortgage on an asset they own.
A long holding period makes that trade much easier to justify. Someone paying £1,500 all-in for a shared ownership home that would cost roughly £2,000 to rent privately has a meaningful monthly saving and builds some equity at the same time.
Someone paying £1,900 once mortgage, rent and service charge are combined gets a far weaker deal.
London Living Rent also deserves attention where it is actually available. City Hall says the 2026–27 average two-bedroom London Living Rent is around £1,409 a month, compared with its referenced market-rent benchmark of £2,168. A household able to secure one of those homes may be better off renting cheaply and building a conventional deposit rather than immediately taking on shared ownership costs.
Availability is the obvious limitation. Shared ownership has a much bigger role precisely because most London renters cannot simply choose a heavily discounted London Living Rent home.
Who should still buy shared ownership in London today?
The strongest shared ownership buyer today is someone with a stable income, a small deposit, a long time horizon and a property with boringly low service charges.
“Boring” is a compliment here. A modest block with transparent accounts, no looming major works and manageable communal costs is far more attractive than an amenity-heavy development with concierge services, gyms, lifts and a service charge already pushing £400 or £500 a month.
We would also want enough financial room for three things to rise together: the mortgage payment after refinancing, rent on the unsold share and the service charge. If a household can afford the property only while all three remain at today’s level, the purchase is too tight.
Time matters just as much. Five to seven years is a much healthier horizon than two or three because the buyer has more opportunity to repay mortgage principal, absorb transaction costs and wait through a weak property market.
The least convincing buyer is someone who is only a small step away from buying normally. If another year of saving opens the door to an acceptable conventional flat, keeping a housing association as co-owner may be a poor trade for saving twelve months.
| London buyer | Shared ownership verdict | Main reason |
|---|---|---|
| Stable income, small deposit, staying 7+ years | Good fit | Deposit barrier is the main problem |
| Almost able to buy outright | Usually weak fit | Conventional ownership may soon be possible |
| Likely to move within 2–3 years | Poor fit | Resale friction matters too much |
| Low, stable service charge | Attractive | Running costs remain manageable |
| High or fast-rising service charge | High risk | Cheap deposit can become misleading |
| New-model lease with repair protection | Better fit | Stronger lease terms |
| Buyer depending on rapid staircasing | Risky | Future affordability is uncertain |
| Comfortable remaining a partial owner | Better fit | Full staircasing is not required for the purchase to work |

What each area costs, what it rents for, how long it sits before it sells. Plus the things nobody writes down: what a short lease will cost you to fix, and why an accepted offer here means nothing until exchange.
Is shared ownership still worth it in London?
Yes, but shared ownership is worth it in London for a narrower group of buyers than the low deposit makes it appear.
The scheme’s best feature remains extremely strong. With London flats averaging around £431,000, buying a 25% share can reduce an illustrative £43,100 full-purchase deposit to roughly £5,400. Few other routes into London homeownership can change the initial cash requirement that dramatically.
Current London rents also keep shared ownership relevant. Private rent averages £2,317 a month, so a carefully chosen shared ownership home can still leave a household paying less each month while building some equity.
The trouble starts when a buyer assumes the cheap entrance means the whole deal is cheap. Shared ownership rent rises. Service charges can rise much faster. Mortgage rates eventually reset. Buying another share costs real money. Selling has more steps. A falling flat market can hurt the equity already owned.
The newer lease model has genuinely improved shared ownership. Minimum shares can start at 10%, qualifying owners can buy 1% increments, standard staircasing can start at 5%, newer leases are much longer and some homes receive a 10-year initial repair period. Those changes make a current-model property noticeably better than many older shared ownership homes.
Service charges remain the weakness we would worry about most today. The government has now explicitly recognised that these costs can stop owners from staircasing, which gets very close to the central problem with the tenure: a household can successfully “get on the ladder” and then find that the running costs leave little money to climb it.
Our threshold is therefore simple. Shared ownership is still worth considering when the deposit or mortgage required for conventional ownership is the one thing keeping a financially stable London household in expensive private rent. Give that buyer a sensible valuation, a good lease, low service charges and a long holding period, and the scheme can work very well.
A £5,000 deposit alone proves almost nothing. If the same property comes with expensive communal charges, poor lease terms and little chance of staying for several years, we would walk away. In London today, the building and the lease can matter more than the percentage being bought.
OUR METHODOLOGY
This analysis tests whether shared ownership still solves the part of London’s homeownership problem it is actually designed to solve: helping households that can sustain substantial housing costs but cannot clear the deposit or mortgage hurdle for a conventional purchase.
We broke the question into the parts that determine whether the tenure works in practice: the cash needed to get in, monthly affordability, how rent and service charges evolve after purchase, repair obligations, staircasing, resale friction, exposure to falling flat prices and the alternatives available to the same household.
For prices and rents, we prioritized official market data. The main benchmarks come from the UK House Price Index and HM Land Registry for London property values and property-type changes, the Office for National Statistics for London private rents, and the Bank of England for the effective rate on newly drawn mortgages used in our worked payment examples.
For how shared ownership works today, we relied on current GOV.UK shared ownership guidance, including the eligibility rules, deposit structure, rent on the unsold share, staircasing, selling process and purchasing costs. We kept the newer shared ownership model separate from older leases wherever the rules materially differ.
The newer-model terms are drawn from the government’s guidance for lenders, landlords and conveyancers and the Homes England Capital Funding Guide. These are the main sources for the 10% minimum share on some homes, 5% standard staircasing, 1% annual increments, 10-year initial repair period, 990-year minimum leases and shorter nomination period on newer homes.
For the harder question of whether the tenure works after purchase, we used parliamentary evidence rather than relying only on scheme rules. The House of Commons shared ownership inquiry is the main source for staircasing rates and affordability concerns, while a recent parliamentary answer on service-charge affordability is used for the government’s acknowledgement that ongoing costs can make staircasing harder.
We also used recent Housing Ombudsman decisions involving Notting Hill Genesis and Metropolitan Thames Valley Housing as practical evidence of how service-charge handling and explanation can go wrong. These cases are not treated as proof that every provider has the same problems.
For London-specific buyer profiles and alternatives, we used City Hall data on shared ownership household incomes, the Mayor of London’s shared ownership guidance, and the current London Living Rent benchmarks.
Our worked comparisons deliberately reuse the same London flat benchmark wherever possible. Citywide averages are reference points rather than valuations of a specific property, and the examples are there to show how the ownership structure changes deposits, mortgage payments and rent rather than to imply that every shared ownership home has the same economics.
The final judgment comes from combining those pieces rather than letting one attractive or unattractive number decide the answer. The threshold we use is whether shared ownership removes the specific barrier preventing a financially stable household from buying conventionally without replacing it with an unsustainable long-term cost, lease or exit problem.
