The Housing Act 1980 was an Act of Parliament passed by the Parliament of the United Kingdom that gave five million council house tenants in England and Wales the Right to Buy their house from their local authority. The Act came into force on 3 October 1980 and is seen as a defining policy of Thatcherism. In Scotland the Right to Buy was provided by the Tenants' Rights, Etc.

If one was a tenant for over 20 years they got a 50% discount. Those not allowed to buy were tenants of charitable housing associations.
