Shared Ownership Explained: How It Works in the UK

Last updated: May 2026 · 7 min read

Shared Ownership is a government-backed scheme that lets you buy a share of a property (between 25% and 75%) and pay rent on the remainder to a housing association. It is designed for people who cannot afford to buy outright on the open market, and it has helped hundreds of thousands of people get on the property ladder.

How Does Shared Ownership Work?

You buy a percentage of the property using a mortgage and deposit (just as with any other purchase), and pay rent on the share you do not own. The rent is set by the housing association, typically at 2.75% of the unsold share per year. For example, if you buy 50% of a 250,000 pound property, you need a mortgage for 125,000 pounds and pay rent on the remaining 125,000 — roughly 286 pounds per month in rent, plus your mortgage payment.

Who Is Eligible?

Your household income must be 80,000 pounds or less (90,000 in London). You must be a first-time buyer, a previous homeowner who cannot afford to buy now, or an existing shared owner looking to move. You must not be able to afford to buy a suitable home on the open market. Military personnel get priority on some developments.

Staircasing: Buying More Shares

You can buy additional shares in your property over time, a process called staircasing. Each time, the property is valued at current market rates, so if prices have risen, you pay more per percentage than you originally did. Once you own 100%, the property is fully yours and you stop paying rent. Some housing associations allow staircasing in 5% increments; others require a minimum of 10%.

Stamp Duty on Shared Ownership

You have two options. You can pay stamp duty on just the share you are buying (lower upfront cost but you pay again when you staircase) or elect to pay stamp duty on the full market value upfront. For most buyers purchasing smaller shares, paying on the share is cheaper overall. Calculate what you would owe using the stamp duty calculator.

Pros and Cons

Pros: Lower deposit required (5% of your share, not the full property value). Monthly costs can be lower than renting privately. You benefit from capital growth on your share. The 2021 model lease includes a 10-year repair period where the housing association covers major repairs.

Cons: You pay both a mortgage and rent. Selling can be slower — the housing association has a nomination period to find a buyer. Service charges and ground rent can be high. Leasehold restrictions apply. Pets, subletting and alterations may require permission. Staircasing to 100% at higher values can be expensive.
