Houses: discount starts at 35% after 3 years, +1% per additional year, maximum 70%. Flats: start at 50%, +2% per year, maximum 70%. Discount caps (2025/26): London £116,200, Rest of England £87,200.

If you sell within 5 years of buying, you must repay a portion of the discount. The clawback is based on the proportion of the original discount, applied to the current sale price — not the original purchase price.

The clawback is calculated on the sale price, not the purchase price. If your home rises in value and you sell in year 1, you repay more than 100% of your original discount. Factor this into your plans carefully.

Earlier public sector tenancies (council housing in different areas, NHS accommodation, police housing) can count toward the qualifying period. Speak to your landlord about combining tenancy periods.

The 5-Year Discount Clawback

If you sell your Right to Buy property within 5 years of purchase, you must repay a proportion of the discount. The clawback is calculated as a percentage of your original discount applied to the current sale price — not the original purchase price. This means if your property has risen in value, you repay more than your original discount in year 1.

Year 1 sale: repay 100% of proportionate discount
Year 2 sale: repay 80% of proportionate discount
Year 3 sale: repay 60% of proportionate discount
Year 4 sale: repay 40% of proportionate discount
Year 5 sale: repay 20% of proportionate discount
Year 6+: no clawback

Example: Right to Buy Calculation

David buying his council house after 12 years in Leicester

David has been a secure council tenant for 12 years in a house valued at £220,000 in Leicester (rest of England).

Property Value£220,000
Years as Tenant12 years
Discount Rate (house)35% + 9% = 44%
Discount Amount (44%)£96,800
Discount Cap (England)£87,200 applied
Purchase Price£132,800
Monthly Mortgage (4.8%, 25yr)£762/month
Instant Equity£87,200

David had been paying £850/month in rent. His mortgage is lower, and he immediately owns £87,200 of equity in the property.

Frequently Asked Questions

You must be a secure council tenant or assured housing association tenant (where the scheme applies), have lived in public sector housing for at least 3 years (cumulative, not necessarily consecutive), and the property must be your main and only home. You must not be bankrupt, subject to a possession order, or have an anti-social behaviour injunction against you.
The discount is capped at 70% of the property value or the monetary cap, whichever is lower. In 2025/26 the monetary cap is £87,200 in England and £116,200 in London. The cap is reviewed annually. To reach 70%, you need at least 38 qualifying years for a house (35% + 35 years at 1% each) or 13 years for a flat (50% + 10 years at 2% each).
Most Right to Buy buyers do not need a cash deposit because the discount acts as equity. Many lenders will offer a 100% mortgage based on the discounted purchase price, using your built-up discount as the effective deposit. You will still need cash to cover legal fees (around £1,000-£2,000), a survey (£300-£600), and any mortgage arrangement fees.
No. The right of first refusal means you must offer the property to your former landlord first if you decide to sell within 10 years, but you cannot be forced to sell. If the landlord declines or does not respond within 8 weeks, you sell on the open market. The sale is always at full market value — you are not forced to accept a below-market price.
If you sell in year 3, you repay 60% of the discount. Importantly, the repayment is based on the current sale price, not your original purchase price. So if the property has risen in value, you repay more in cash than you originally received as a discount. After 5 years there is no clawback obligation. After 10 years the right of first refusal also ends.
