Shared Ownership: Rights, Costs, and What Can Go Wrong

Last updated: Checked against primary legislation on legislation.gov.uk

Shared ownership allows you to buy a share of a property (usually between 10% and 75%) and pay rent on the remaining share to a housing association. It was designed to help people onto the property ladder, but it comes with significant risks and obligations that are often not made clear at the start. This guide explains how shared ownership works, your rights as a shared owner, the true costs involved, and what to do if you face problems.

How shared ownership works

In shared ownership:

  • You buy a share of the property, typically between 10% and 75%, using a mortgage and/or savings
  • You pay rent to the housing association on the share you do not own
  • You pay a monthly service charge for maintenance of communal areas and the building
  • You own a leasehold interest, not freehold, and the housing association (or landlord) owns the freehold
  • You are responsible for all maintenance and repairs inside your home, just like a full owner
  • The Shared Ownership model was overhauled in April 2021, new-model shared ownership has different rules to older leases
New model vs old model: Properties built after April 2021 use the new model of shared ownership, which includes a 10% minimum share (down from 25%), 1% staircasing options, and a 10-year landlord repair period. Older shared ownership leases may have fewer protections. Check your lease carefully.

The true costs of shared ownership

Shared ownership often costs more per month than people expect. The full monthly outgoings typically include:

Mortgage repayments
On the share you own, typically a repayment mortgage.
Rent to housing association
Usually around 2.75% of the unsold share per year. So on a £250,000 property where you own 25%, the remaining 75% (£187,500) generates ~£5,156/year (£430/month) in rent. Rent increases annually, often by RPI +0.5% or CPI +1% depending on your lease.
Service charges
Can range from £100 to £500+ per month on new builds. Covers building insurance, communal cleaning, lifts, gardening, management fees. Can increase substantially year on year, and you have limited ability to challenge increases.
Ground rent
Older shared ownership leases may include ground rent. New leases since 2022 must have a peppercorn (zero) ground rent under the Leasehold Reform (Ground Rent) Act 2022.
Buildings insurance
Usually included in the service charge, but you are responsible for contents insurance.
Rent and service charges can increase significantly year on year. Many shared owners find their monthly outgoings rise to the point that they can no longer afford them, particularly when both rent and service charge increase at the same time. Always model future cost increases before buying.

Staircasing, buying more of your home

Staircasing means buying additional shares in your property over time, reducing the rent you pay. The rules depend on whether you have a new-model or old-model lease:

FeatureNew model (post-April 2021)Old model (pre-April 2021)
Minimum staircase purchase1% of property valueUsually 10% of property value
Maximum ownership via staircasing100% (full ownership)100% (but some rural exception properties are capped at 80%)
How many times can you staircase?Unlimited (1% tranches up to 3 per year)Usually unlimited in 10%+ tranches
Valuation required?Yes, RICS valuation at your cost (£250 to £500+)Yes, RICS valuation at your cost
When does rent reduce?Proportionally as you buy more sharesProportionally as you buy more shares
  • Staircasing is based on the current market value, not your original purchase price
  • If property values rise, staircasing becomes more expensive over time
  • Once you staircase to 100%, you own the property outright (freehold if the housing association agrees to transfer it)
  • Each staircase transaction involves legal fees, SDLT, and valuation costs, budget £1,500 to £3,000+ per transaction
  • Rural exception properties: some rural shared ownership leases cap ownership at 80%, check your lease

Selling your shared ownership property

Selling a shared ownership property is more complicated than selling a freehold home:

1
Notify your housing association
You must usually give your housing association first right of refusal, known as the 'nomination period'. This is typically 4 to 8 weeks. During this time, they can find a buyer from their waiting list and may conduct a RICS valuation to set the sale price.
2
RICS valuation
The property is valued by a RICS-registered surveyor. This sets the price, you must sell at this price (you cannot negotiate above or below it during the nomination period). You pay for the valuation (typically £250 to £500).
3
Housing association finds a buyer (or not)
If the housing association finds a suitable buyer within the nomination period, the sale goes ahead to that buyer at the RICS valuation price. If they cannot find a buyer, you are free to market the property through an estate agent.
4
Open market sale
If the nomination period expires without a buyer, you can sell on the open market. However, the buyer must be eligible for shared ownership (income and other eligibility criteria apply). This restricts your pool of buyers significantly compared to a normal property sale.
5
Complete the sale
Conveyancing for shared ownership sales is more complex than a standard sale, use a solicitor experienced in shared ownership. The housing association must approve the buyer. Budget for additional legal fees.
If the market has fallen since you bought, you may not be able to repay your mortgage from the sale of your share, particularly if you only own a small percentage. Negative equity is a real risk in shared ownership. Always take independent financial advice before buying.

Service charge disputes

Service charges are one of the most common sources of dispute for shared owners. As a leaseholder, you have important rights:

  • Service charges must be 'reasonable', you can challenge unreasonable charges at the First-tier Tribunal (Property Chamber)
  • You have the right to request a summary of service charge accounts and inspect supporting receipts and invoices
  • Your housing association must consult you before carrying out major works costing more than £250 per leaseholder, this is the Section 20 consultation process
  • If they fail to consult, they cannot recover more than £250 per leaseholder for those works from service charges
  • You can apply to the First-tier Tribunal to challenge the reasonableness of service charges, or to determine what charges are payable
  • You can apply to the Tribunal for the right to appoint your own managing agent if the current management is inadequate
Keep records of all service charge demands, communications with your housing association, and any Section 20 consultation notices. If you dispute a charge, do so in writing within the time specified on the demand. Paying under protest preserves your right to challenge later.

Repairs and maintenance

Responsibility for repairs in shared ownership depends on whether they are communal (building association's responsibility) or internal (your responsibility):

  • You are responsible for internal repairs, decorating, appliances, fixtures and fittings
  • The housing association is responsible for structural repairs, the roof, external walls, communal areas, and shared services
  • Under the new model (post-April 2021): your housing association must repair structural defects for the first 10 years, even if this would normally fall to you
  • If you can't get repairs done by the housing association, escalate to the Housing Ombudsman (free, independent)
  • Damp and mould: if the cause is structural (e.g. a failing roof or external wall), the housing association must repair it, see our damp and mould guide for enforcement options
  • Buildings insurance (included in your service charge) covers structural damage, not contents

Lease length and extension

As a leaseholder, your lease has a set term, most shared ownership leases start at 99 or 125 years. A short lease can make your property very difficult to mortgage and sell:

  • When a lease falls below 80 years, it becomes difficult to remortgage or sell
  • Lenders typically want at least 70 to 85 years remaining on the lease at the end of the mortgage term
  • You can extend your lease, but unlike private leaseholders, shared owners have a more complicated route
  • Under the Leasehold Reform, Housing and Urban Development Act 1993, shared owners who have staircased to 100% have the standard right to extend the lease by 90 years
  • Shared owners who have not staircased to 100% may be able to negotiate an extension with their housing association, but there is no statutory right until ownership is 100%
  • The Leasehold and Freehold Reform Act 2024 proposes reforms that may improve shared owners' rights to extend leases
If you are considering a shared ownership property with a lease of less than 125 years, take independent legal advice about the cost of future lease extension and the impact on resale value. Short leases are one of the most common sources of financial distress for shared owners.

What to do if things go wrong

Frequently asked questions

How does shared ownership work?

You buy a share of a property (usually 10 to 75%) with a mortgage and/or savings, and pay rent to the housing association on the remaining share. You also pay a monthly service charge for building maintenance. You can increase your share over time through 'staircasing', buying additional portions until you own the property outright. Under the new model (post-April 2021), you can staircase in 1% increments.

What is staircasing in shared ownership?

Staircasing means buying additional shares in your property to increase your ownership stake and reduce the rent you pay. Under new-model shared ownership (post-April 2021), you can buy as little as 1% at a time (up to 3 times per year). Under older leases, the minimum was typically 10%. Each staircase is based on the current market value, not your original purchase price, and involves valuation, legal, and SDLT costs.

Can I sell my shared ownership property?

Yes, but the process is more complex than a normal sale. You must usually give the housing association a nomination period (4 to 8 weeks) to find a buyer from their waiting list. The sale price is set by a RICS valuation, you cannot negotiate above it. If the housing association cannot find a buyer, you can market on the open market, but the buyer must still meet shared ownership eligibility criteria. Use a solicitor experienced in shared ownership.

Can I challenge my service charge?

Yes. Service charges must be reasonable. You can apply to the First-tier Tribunal (Property Chamber) to challenge whether charges are reasonable or payable. Your housing association must consult you (Section 20 consultation) before carrying out major works costing more than £250 per leaseholder, if they don't, they cannot recover more than £250 from service charges for those works. You can also request a summary of accounts and inspect the underlying invoices.

What happens if I can't keep up with shared ownership costs?

Contact your housing association immediately, before you fall into arrears if possible. Many have hardship schemes and can arrange temporary rent reductions or payment plans. Also contact your mortgage lender. If you are at risk of eviction for arrears, get advice from Shelter urgently, you have legal defences and time to resolve the situation. In serious financial difficulty, seek advice from Citizens Advice or a debt charity about whether shared ownership is sustainable.
