What if Britain had never sold the council houses?

The council house was sold once, in 1980. The bill for renting it back was written every year since, by everyone else.

It is a good week to be Margaret Thatcher's ghost, because everything is her fault again. The new Prime Minister has settled on a favourite explanation for Britain's housing troubles, and it wears a handbag. Right to Buy, the policy that let council tenants buy their homes at a discount, is the most recognisably Thatcherite thing on the statute book, so it is the natural place to test whether the blame survives contact with the arithmetic.

It does not. Not because Thatcher was blameless, but because the number that actually hurts today was run up long after she left, by the governments now pointing at her. Selling the homes was defensible. Failing to replace them, and then choosing to rent them back through the benefit system rather than build, was a separate decision, taken again and again, by Prime Ministers of both parties, including the one holding the handbag up as an alibi.

Start with the uncomfortable truth for anyone who wants this simple. A council house is a bad asset to hold. GBTT has shown the arithmetic twice: a social home that costs about £200,000 to build is carried at roughly £85,000, because the thing it produces, the right to collect around £106 a week in rent for thirty years, is worth so little once discounted. The same home would fetch about £275,000 on the open market. One house, a £115,000 hole between what it cost and what the state values it at.

And that home is not free to keep. Councils and housing associations now spend between £3,000 and £5,000 a year per home on management and maintenance, a bill that reached £8.8bn across England in a single year. Put the two together and the honest picture is not a golden asset flogged off by vandals. It is a low-yielding home, let below cost, soaking up thousands a year in upkeep, that the state was subsidising to own. When a sitting tenant offered to take it, maintain it, and stop drawing the subsidy, selling was reasonable public finance. The scandal was never that Britain sold. It was the terms, and what came next.

The blame skips over one fact. Right to Buy did not come with a plan to rent the homes back. The machine that now does exactly that, Housing Benefit paying near-market rents to private landlords, was not part of the policy Thatcher implemented. The decision to let it balloon belongs to the governments that followed her.

They made a choice, over decades, and it has a name in the trade: bricks to benefits. Instead of funding councils to build homes, the state increasingly funded tenants to rent them, at whatever the market charged, and made up the difference in benefit. Britain's housing support bill is now around £30bn a year, a large and rising share of it flowing to private landlords. That is not the residue of a 1980 sale. It is the running cost of forty years of deciding it was easier to pay rent than to lay bricks. Thatcher sold the stock. Her successors built the subsidy that now rents it back, and kept building it, Budget after Budget.

Two decisions turned a reasonable sale into a lasting bill, and only the first is Thatcher's. The discount was hers: the state sold not at the £85,000 the home was worth to it, nor near the £275,000 it was worth on the market, but at a markdown of up to 70%, handing most of the open-market value to the buyer and, often, to whoever bought it next. Britain sold the council houses, and marked them down to clear.

The second decision was made by everyone since. 2.4 million homes have gone since 1980, about 1.9 million in England, and for most of that time the replacement rate was a rounding error. Sell the stock, pocket the receipt, build nothing back, and let the waiting list grow. Every government had forty years to reverse it and chose not to, through boom and bust, majority and coalition. The missing homes are not a Thatcher policy. They are a cross-party habit.

Put the two together and you get the absurd position Britain is in now. Around four in ten of the homes sold under Right to Buy, roughly 780,000 in England, worth about £176bn, are owned by private landlords. Many are let to tenants on benefit. So the state sold the home, shed the maintenance, and now rents the same house back from a private owner at the market rate it used to undercut.

A former council home let privately costs the taxpayer on average over £1,500 a year more in Housing Benefit than the same household in council tenure, and up to £5,200 a year in some London boroughs, an extra £1.5bn a year in total. Be honest about the offset: by selling, the state no longer pays that £3,000-to-£5,000 maintenance bill, so the rent-back premium is not pure loss. But it is still a worse deal, because the homes were never replaced. Had the receipts been rebuilt into new stock, the state would own an appreciating asset and pay neither the premium nor a private landlord. Instead it owns nothing and pays both.

The strangest thing about blaming Thatcher in 2026 is that the country already settled the argument, across every party, without her name attached. England has cut the Right to Buy discount from up to 70% to a maximum of 15%, and raised the qualifying period from three years to ten. Scotland abolished the scheme in 2016; Wales in 2019. On its original terms it has no defenders left in government.

So the live question is not whether Right to Buy was flawed. Everyone agrees it was. The live question is why, having agreed, the same governments still will not build, and still funnel £30bn a year into rent instead. Answering that means looking in a mirror, not at a portrait of a dead Prime Minister. The handbag is a way of changing the subject.

What the public purse carries now, once a private landlord owns the home the council sold.

Notice what actually happened to the subsidy. It did not disappear. It moved from a modest, permanent subsidy on a home the state owned, to a larger, permanent subsidy on a home a private landlord owns, and the paperwork changed hands from Thatcher to everyone after her. The tenant is often the same family in the same house. Only the landlord, and the party in power, changed.

And £1.5bn is only the premium on the sold homes. It sits inside a £30bn housing-support bill, alongside the temporary accommodation for families who never reached the front of a shorter list, and the discount gifted away on 2.4 million sales. This is not a bill you settle once. It is the standing cost of a habit no government since 1980 has been willing to break: paying for rent because it is easier than paying for bricks.

This is where housing articles usually pick a team, so we won't. Four things are true at once, and a file that tells you only one of them is selling something.

First, for the buyer, Right to Buy was a gift and a good one. Millions of working families got an asset, a stake and a door of their own, often the best financial decision of their lives. Pretending it was a con played on its own tenants is a lie the other way.

Second, selling was defensible, and keeping was not free. A council home is low-yielding, let below cost, and runs £3,000 to £5,000 a year in upkeep. The state was subsidising an asset to hold it. Selling a subsidised home to the family in it, at a fair price, would have been sound public finance. The problem was the price, not the principle.

Third, the discount was the giveaway, and Thatcher owns it. Marking homes down by up to 70% handed away the market value the state could have banked. That is a real, permanent loss, and it is hers. What is not hers is what happened to the money afterwards, or rather what did not: the homes were never rebuilt.

Fourth, and this is the important one, the bill that hurts now was written by her successors. Housing Benefit renting the homes back, the bricks-to-benefits switch, the £30bn support bill, the forty-year refusal to build, none of that was in Right to Buy. It was chosen, repeatedly, by every government since, and it is still being chosen by the one blaming her today. Scotland and Wales scrapped the scheme; England gutted it. The argument is over. The scapegoat is forty-six years old, and the people reaching for it are the ones still not laying bricks.

Britain did not fail by selling its council houses. A subsidised, high-maintenance home is a hard thing to justify holding, and handing one to the family already in it was fair. Britain failed by selling them too cheap, and then by making the same choice every year for forty years: pay rent, not for bricks. The result is a state that sold homes to stop subsidising rent, and now subsidises rent to a private landlord instead, on the very same houses, at a premium, inside a £30bn bill that grows whoever is in charge.

That bill is not Thatcher's alibi to carry alone. She sold the stock and set the discount. Every Prime Minister since, up to and including the one now holding her responsible, took the receipt, declined to build, and let the rent-back bill climb. Blaming 1980 is a way of not explaining 2026.

Britain sold the council houses to stop paying for them, and pays more than ever, to someone else, for the same roofs. The tenant kept renting. The taxpayer kept subsidising. The landlord got to leave, and so did the blame. That was the deal, and the receipt is still printing, in a hand that changes with every election.
