Correct.
You qualify through low income, and as the list to get council housing is long, need is taken into account also.
Right to Buy allows council tenants to buy their homes at a substantial discount on market value. This is alright, as it promotes stability and gives tenants equity, but at the same time, council tenants don’t get evicted anyhow, even if their income has become very high, and you can pass on a tenancy when you die if a relative was living in the council house with you.
But the money from the sale of council houses to tenants does not get ploughed back into buying or building more council housing, and the people who bought them can in turn sell them on the open market rather than back to the council.
This has made it near impossible for councils to maintain levels of housing stock, let alone increase it to reflect population growth. In central London, many types of essential worker are hard to obtain as too few can afford to live within commuting distance - large & high quality housing estates in the centre and all through the Boroughs having been sold off under the scheme long ago & snaffled up by developers.
Thatcher brought it in as a populist policy, and to weaken state services, but every other PM after permitted the policy to carry on unaltered.
Getting fees out of clients is like getting blood out of a stone.
Those barristers may not get paid by Tesco for years & not without a fight - they’re prohibited from taking retainers and from turning down cases, and though they can refer cases on to other barristers, the circumstances in which they can do this are very limited.
