For houses, the Right to Buy scheme offers a discount of 35% if you’ve lived there for between three and five years. If you’ve lived there longer, you’ll get an extra 1% discount for each year you’ve lived there above five years, with the maximum discount being set at 70% (or £84,200 and £112,300 in London - whichever is lower). It’s applied slightly differently to flats - the base discount is 50% and the discount increases by 2% for every year you’ve lived there above five years. The maximum discount is the same as for houses.
