What is Shared Ownership?

Shared ownership is a government-backed homeownership scheme that allows you to buy a share of a property — typically between 10% and 75% — and pay a subsidised rent on the remaining share, which is owned by a housing association. Over time, you can buy additional shares (staircase) until you own 100%.

It is designed for people who want to own their home but cannot yet afford to buy outright on the open market. Unlike Help to Buy (which ended in 2023), shared ownership is still available for both new-build and resale properties, and there is no end date announced for the scheme.

Shared ownership properties are always leasehold. You hold a long-term lease (typically 99–125 years) from the housing association, and the property is on freehold land owned by the association or a freeholder.

Who Provides It and Who Is Eligible?

Shared ownership properties are provided by housing associations (also known as registered providers). These are not-for-profit organisations that develop and manage affordable housing. Some local authorities also offer shared ownership.

Eligibility criteria (England)

Some properties have additional requirements, such as a local connection to the area, or priority for key workers (NHS, teachers, emergency services). Always check the specific criteria with the housing association.

Military personnel have access to shared ownership through the HOLD (Home Ownership for people with Long-term Disabilities) scheme, and the OPSO (Older Persons' Shared Ownership) scheme is available for those aged 55+.

Finding a Property

The main portal for finding shared ownership properties in England is Share to Buy (sharetobuy.com) and Own Your Home (ownyourhome.gov.uk). Housing associations also list their own properties directly.

You can search by area, property type and share percentage. Most shared ownership properties are flats, though houses are available in some developments, particularly outside London.

When you find a property, you will need to register your interest with the housing association and complete an initial eligibility assessment, typically a short online or phone form.

The Buying Process

The shared ownership purchase process has several steps beyond a standard property purchase:

  1. Eligibility check — the housing association confirms you meet the criteria
  2. Financial assessment — an independent financial adviser (often arranged by the housing association) assesses which share you can afford
  3. Reservation — you pay a reservation fee (typically £200–£500) to hold the property
  4. Mortgage application — you apply for a mortgage on your share (minus your deposit). Not all lenders offer shared ownership mortgages; specialist lenders include Nationwide, Halifax and Coventry BS.
  5. Solicitor — instruct a solicitor experienced in shared ownership. The legal process is more complex than a standard purchase because of the leasehold structure and housing association involvement.
  6. Survey — arrange a valuation survey (required by the mortgage lender) and a full homebuyer's report if desired
  7. Exchange and completion — as with any property purchase, exchange contracts and complete on the agreed date

The process typically takes 3–6 months from application to completion for a new build, and 2–4 months for a resale. New builds frequently have delays if construction is not yet complete.

Monthly Ongoing Costs

Shared ownership is a hybrid of buying and renting, so your monthly outgoings include three elements:

Example Monthly Costs: 40% Share of £280,000 Property

Share value (40% of £280,000)£112,000
Deposit (10% of share)£11,200
Mortgage (4.8%, 25 years, repayment)£553/month
Rent on unsold share (60% × £280,000 × 2.75% ÷ 12)£385/month
Service charge£150/month
Total monthly housing cost£1,088/month

The rent on the unsold share

The housing association charges you rent on the share they own, calculated at a percentage of that share's current market value. The typical rate is 2.75% per annum of the unsold share's value, charged monthly. So on a £168,000 unsold share: £168,000 × 2.75% ÷ 12 = £385/month.

This rent increases each year, usually by RPI + 0.5%. Check your lease for the exact formula. This escalation means the cost of not staircasing increases over time.

Service charges

Service charges cover the maintenance of communal areas, building insurance, management fees, and sometimes a sinking fund for major repairs. They vary enormously — from £50/month on a small estate to £400+/month on a managed apartment block in a city centre. Always request a breakdown of service charges and ask for the last three years' accounts before purchasing.

Service charges are not fixed. They can be challenged through the First-tier Tribunal (Property Chamber) if you believe they are unreasonable.

Ground rent

Under the Leasehold Reform (Ground Rent) Act 2022, new leases granted from 30 June 2022 must charge zero or peppercorn ground rent. Shared ownership properties created after this date have zero ground rent built into the standard lease. Older properties may still have ground rent — check the lease carefully.

Staircasing: Buying More Shares

Staircasing is the process of buying additional shares in your home over time. It is one of the key features of shared ownership — the path to eventual outright ownership.

Traditional staircasing (older leases)

Traditional staircasing allows purchases in minimum tranches of 10%. You need a new RICS valuation each time. When you staircase to 80%+, you will also pay SDLT on that transaction (if you did not elect to pay on the full market value at purchase). Once you reach 100%, rent to the housing association ceases and you hold the property outright.

Gradual staircasing (new model lease, from April 2021)

Properties built under the new model lease allow gradual staircasing — you can buy as little as 1% of the property per year without needing a full valuation. The price for 1% tranches is based on the average house price growth in your area over the previous year. This makes staircasing more accessible and helps you build equity incrementally.

Important: The price for each staircasing tranche is based on a new valuation at the time — not your original purchase price. If house prices have risen since you bought, you will pay more for each additional share. This is a key risk with shared ownership in rising markets — the shares get more expensive to buy the longer you wait.

Selling Your Shared Ownership Home

Selling is more complex than selling an outright property. The process:

  1. Notify the housing association that you wish to sell
  2. The housing association commissions a RICS valuation at your cost (typically £250–£500)
  3. The housing association has a nomination period (typically 4–8 weeks) to find a buyer for your share. During this time, they market the property through their own channels and to people on their waiting list.
  4. If the housing association finds a buyer, the sale proceeds at the valuation price. You receive the sale price for your share only (not the full property value).
  5. If no buyer is found within the nomination period, you can list the property on the open market — but the buyer must still meet shared ownership eligibility criteria, unless you have staircased to 100%.

This process means selling can take longer than a standard sale. Budget for additional legal costs (£1,500–£3,000) and allow 3–6 months for the transaction.

Subletting Rules

In almost all cases, you cannot sublet a shared ownership property. The scheme is designed for owner-occupiers, not investors. Subletting without written consent from the housing association is a breach of the lease and could put your home at risk.

If your circumstances change and you need to move but cannot sell, you must contact the housing association to discuss options — which may include being allowed to surrender the lease, swap properties or, in exceptional circumstances, let with consent.

Stamp Duty on Shared Ownership

There are two approaches to SDLT on a shared ownership purchase:

First-time buyers can claim first-time buyer SDLT relief under either approach (up to the relevant thresholds). Your solicitor can calculate which approach is more cost-effective for your specific situation.

Frequently Asked Questions

You must have a household income below £80,000/year (£90,000 in London), be a first-time buyer or former homeowner who can no longer afford to buy, not currently own a home, and demonstrate you cannot afford to buy on the open market. You must be at least 18 with the right to live in the UK. Some properties have additional local connection or key worker requirements.
Staircasing means buying additional shares in your shared ownership home. Under new model leases (April 2021+), you can staircase in 1% increments annually or in larger tranches. Each tranche is priced at current market value via a new RICS valuation. Once you reach 100%, rent to the housing association stops.
The housing association has a nomination period (4–8 weeks) to find a buyer for your share. If unsuccessful, you can sell on the open market, but the buyer must meet shared ownership eligibility criteria (unless you have staircased to 100%). The process takes 3–6 months and involves additional legal complexity and cost compared to a standard sale.
Yes. The rent on the unsold share is reviewed annually and typically increases by RPI + 0.5%. This means your housing costs rise each year unless you staircase. Over a 10-year period, significant rent escalation can make shared ownership more expensive than anticipated if you do not increase your share ownership.
Generally no. Subletting without written consent from the housing association is a breach of the lease. The scheme is designed for owner-occupiers. If your circumstances change, contact the housing association to discuss options — they may offer solutions such as lease surrender or a managed transfer, but subletting is not normally permitted.
It depends on your circumstances and plans. It works best if you plan to staircase progressively and eventually own outright — in that case you benefit from house price growth on the full value and gradually eliminate the rent. If you stay at a low share for a long time, rising rent and service charges can make it expensive. It is generally better value than renting if you plan to stay in the same area long-term.
