The Housing Act 1980 came under Michael Heseltine's remit as he was Environment Secretary at the time. On proposing the bill to Parliament in 1979 Heseltine said it "lays the foundations for one of the most important social revolutions of this century". Gerald Kaufman, then in the Labour Party Shadow Cabinet and a former Environment Minister himself, said the Act would "not provide a single new home and deprive many homeless people or families living in tower blocks from getting suitable accommodation". The Labour Party was vehemently opposed to the Act but by the general election of 1987 had dropped its opposition to the Right to Buy. The Act allowed tenants who had lived in their homes for at least three years to buy at 33% discount of the market price and 44% for a flat. 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. However many of the houses sold were built in the 1950s and 1960s, they were of poor quality and are today referred to as non-traditional housing, many had serious structural defects and were designated defective, the passing of the Housing Defects Act 1984 was required to allow for grants to be given to unsuspecting buyers, and to implement a cut off date for the issue of such grants. As a result of increased building costs a further Housing Act 1988 was passed to limit the amount of money payable, and move some types of non-traditional housing into different categories, for different levels of grant. Mortgage-interest tax relief was also in operation and the Act provided the right to a mortgage from the local authority. The Housing Act 1980 introduced the concept known as a 'secure tenancy' which restricted local authorities power to recover possession from their tenants. The Secretary of State had reserve powers to intervene with local authorities if they did not comply with the Act. The Housing Act 1980 also gave those who paid a £100 deposit the right to buy their home at a fixed price in a period of two years after paying the deposit. If the tenant was to sell the home they bought under the Act within five years of purchasing it they would have to share the capital gain between themselves and the local authority.
Home ownership grew from 55% of the population in 1980 to 64% in 1987. By the time Margaret Thatcher left office in 1990 it was 67%. 1.5 million council houses were sold by 1990, by 1995 it was 2.1 million and as a result of the Right to Buy the Treasury received £28 billion. Proponents of the Right to Buy argue that it gave working-class council tenants opportunities to get on the property ladder which they would not otherwise had had without the Act. However, by 2015-16, home ownership had declined from a high of 70.9% in 2003 back to 62.9%, the lowest level since 1985.
One third of ex-council homes owned by wealthy landlords
By 2013, some tenants who had purchased their council flats, sold them later to speculators, investors or property companies. By 2013, a one-bedroom council flat that sold for £50,000 in the early 1990s, for example, had a market price of £250,000. A tight housing market led to increased rent as construction of new homes decreased.
