UK Right to Buy Calculator
Calculate your Right to Buy discount as a council or housing association tenant in England. Uses 2025/26 caps (£87,200 England / £116,200 London).

The Right to Buy discount increases with each year of qualifying tenancy, up to a maximum of 70% or the monetary cap, whichever comes first.

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.
| Year of Sale | Discount Repaid | Amount Repaid (£87,200 discount) | Example: Sell at £262,500 |
|---|---|---|---|
| Year 1 | 100% of discount | £87,200 | £91,560 |
| Year 2 | 80% of discount | £69,760 | £73,248 |
| Year 3 | 60% of discount | £52,320 | £54,936 |
| Year 4 | 40% of discount | £34,880 | £36,624 |
| Year 5 | 20% of discount | £17,440 | £18,312 |
| Year 6+ | 0% — no clawback | £0 | £0 |

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 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 Tenant | 12 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.
