Right to Buy Mortgage Guide UK — Council Tenant to Homeowner.

What is Right to Buy?

Right to Buy is a government scheme that gives eligible council tenants in England the legal right to buy the home they currently rent at a discount. The scheme was introduced by the Housing Act 1980 under the Thatcher government and has since helped over two million council tenants become homeowners.

The core idea is straightforward: if you have been renting your council home as a secure tenant for at least three years, you can apply to purchase it at a price below its full market value. The discount you receive depends on how long you have been a tenant and whether your home is a house or a flat. The scheme only applies in England; Scotland has a separate scheme, Wales ended its scheme in 2019, and Northern Ireland has its own House Sales Scheme.

Who qualifies and how much discount can you get?

To qualify for Right to Buy you must be a secure tenant of a council property in England, have spent at least three years as a public sector tenant (this does not all need to be in the same property), and the property must be your only or main home. You must not be subject to a possession order or have bankruptcy proceedings underway.

The discount you receive increases with the length of your tenancy. For houses, you get 35% off the market value after three years as a tenant, rising by 1% for each additional year up to a maximum of 70%. For flats, the starting discount is 50% after three years, rising by 2% per additional year up to a maximum of 70%. Regardless of the percentage, there is a cash cap: for 2024-25 the maximum discount is £96,000 in London and £127,900 outside London.

Your local council will arrange an independent valuation of your home to determine its market value. The discount is then applied to that valuation to arrive at your purchase price. If you believe the valuation is too high, you have the right to request a re-determination by the district valuer.

Getting a mortgage for Right to Buy

One of the biggest advantages of Right to Buy is that the discount can count as your deposit. If your council home is valued at £150,000 and you receive a £50,000 discount, you are effectively buying a £150,000 property with a £100,000 mortgage — a loan-to-value ratio of just 67%. This puts you in a very competitive LTV band for mortgage rates, even though you have not saved a traditional deposit.

However, lenders still carry out a full affordability assessment. They will look at your income, outgoings, existing debts, and credit history to ensure you can comfortably meet the monthly repayments. If you are on a lower income or have any adverse credit, it is worth speaking to a specialist broker who understands Right to Buy applications and knows which lenders are most flexible.

Most mainstream lenders offer Right to Buy mortgages, and you can choose from fixed-rate, tracker, and variable-rate products just as you would with any other purchase. Your broker will help you compare deals and find the best rate for your circumstances.

Step-by-step Right to Buy process

The Right to Buy application process is more structured than a standard property purchase because your council is legally required to follow specific timescales. Here is what to expect at each stage.

Important considerations before you buy

Right to Buy can be an excellent route to homeownership, but there are several important factors you should weigh carefully before making your decision. The financial commitment extends well beyond the mortgage repayments themselves.

The cost floor rule means that if your council has spent money on repairs or improvements to your home in the 15 years before your application, the discount cannot reduce the price below what the council has spent. This is designed to prevent councils losing money on recently refurbished properties.

If you sell your home within five years of buying it through Right to Buy, you must repay some or all of the discount. In the first year, you repay 100% of the discount; this reduces by 20 percentage points each year, so by year five you repay 20%. After five years there is no repayment obligation. You must also offer the property back to your council or a housing association before selling on the open market during this period.

Right to Acquire for housing association tenants

If you rent from a housing association rather than a local council, you will not qualify for Right to Buy. However, you may be eligible for a similar scheme called Right to Acquire. This gives qualifying housing association tenants in England the right to buy their home at a discount, though the discounts are smaller than those offered under Right to Buy.

To qualify for Right to Acquire, you must have been a public sector or housing association tenant for at least three years, and your housing association must have received public funding to build or buy the property. The discount ranges from £9,000 to £16,000 depending on the region, which is significantly less than the Right to Buy maximum. However, it can still make a meaningful difference to your purchase price and deposit requirements.

The application process is similar to Right to Buy: you submit an application to your housing association, they arrange a valuation, and you receive a formal offer with the discounted price. The same general mortgage options are available, and a broker experienced in social housing purchases can help you find the best deal.
