Shared Ownership New Build Homes: A 2026 Buyer’s Guide
Shared ownership lets you buy a share of a new build home and rent the rest at a subsidised rate. Here is exactly how it works in 2026.
Key points
- Buy 10-75% of a new build with a 5% deposit on that share, then pay subsidised rent on the remainder.
- Eligibility: household income under £80,000 (£90,000 in London) and unable to afford a standard mortgage.
- Rent is capped at 2.75% per year of the value of the unsold share — much less than market rent.
- You can buy further shares (staircasing) at any time, often reaching 100% over time.
What is shared ownership on a new build?
Shared ownership lets you buy between 10% and 75% of a new build home and pay subsidised rent on the share you do not own. Your deposit only needs to cover the share you are buying — so on a £300,000 home, a 40% share is £120,000, and a 5% deposit on that share is just £6,000.
That makes shared ownership the most accessible route into a brand-new home for buyers who cannot afford a full mortgage. Most major housebuilders (Berkeley, Bellway, Bovis, Persimmon, Vistry, Countryside, Latimer, Places for People) now have shared-ownership stock on their flagship developments. The government runs the scheme through housing associations and the Affordable Homes Programme.
Eligibility: who can use shared ownership in 2026?
To use shared ownership you must:
- Have a household income under £80,000 a year (£90,000 in London).
- Be unable to afford a home with a standard deposit and mortgage that meets your needs.
- Be a first-time buyer, a previous homeowner who can no longer afford to buy outright, an existing shared owner moving, or a renter who needs to move for reasons such as a relationship breakdown or job relocation.
- Have a clean credit history (not always required but most lenders prefer it).
How the deposit and rent are calculated
Your deposit is at least 5% of the share you are buying — not 5% of the full property value. On a £300,000 home, a 40% share is £120,000, so the minimum deposit is £6,000. The mortgage covers the rest of the share (£114,000).
Your rent is capped at 2.75% per year of the value of the unsold share. On the same £300,000 home with a 40% share, the unsold 60% is worth £180,000 — so the maximum rent is £4,950 per year, or £412.50 per month. This is typically well below market rent for an equivalent property.
You will also pay a service charge (most apartments) and may pay ground rent on leasehold homes. Check both carefully — they can add £100–£300 per month and are not capped.
Staircasing: buying more of your home
After you move in you can buy further shares — known as staircasing — at any time. Most modern shared-ownership leases (the "new model" introduced in April 2021 for homes funded by the 2021-2026 Affordable Homes Programme) allow you to buy as little as 1% per year at a discounted fee. You can typically staircase all the way to 100% over time, at which point you own the home outright and no longer pay rent.
Each staircasing transaction needs a fresh valuation. The cost of each additional share is based on the home\'s value at the time, not the price you originally paid — so if prices rise, buying further shares becomes more expensive.
Things to watch out for
- Service charges and ground rent. Often the biggest "surprise cost" on shared-ownership flats. Ask for a clear schedule before reserving.
- Lease length. Most are 990+ years. Anything below 80 years is a serious problem for re-mortgaging or selling.
- Selling restrictions. If you have not staircased to 100%, the housing association usually gets first refusal to find a buyer (typically 4 or 8 weeks).
- "100% rent" on the unsold share. You are responsible for 100% of repairs and maintenance even if you only own 25%.
How shared ownership interacts with stamp duty in 2026
You can choose either to pay stamp duty on the full market value at purchase (a one-off bill, potentially lower if you might never staircase) or pay it in stages as you staircase. For most first-time buyers buying under £500,000, choosing to pay on the share you buy first results in £0 stamp duty thanks to the first-time buyer relief.
