Worth Less Than It Cost

The arithmetic was laid out cleanly this weekend on X by John Wills, a social housing veteran who has personally set up a Registered Social Landlord and arranged the transfer of 7,000 homes from a local authority. He gave three numbers. The build cost of a small social housing unit is roughly £200,000, excluding land. The balance-sheet value of that same unit, calculated under the standard thirty-year, five-per-cent discount methodology that every RSL uses to capitalise its stock, is £85,000. A property of the same specification, sold on the open market, would fetch around £275,000.

A private developer building at £200,000 to sell at £275,000 is running roughly the gross margin Persimmon, Barratt and Taylor Wimpey publish in their annual accounts. A social housing provider building at £200,000 to capitalise at £85,000 is, by definition, taking a capital loss of fifty-eight per cent on day one. This is not a cyclical mark-down. It is the deliberate, intended financial structure of the asset.

The grant is a loss provision

The gap between £200,000 spent and £85,000 booked has to be filled by something, or no social housing would ever get built. The something is grant. In the current English programme, Homes England distributes £7.4 billion to deliver up to 130,000 affordable homes outside London by March 2026 — a benchmark of around £57,000 per home. In London, where build costs are higher and recoverable rents lower, grant rates of £150,000 to £200,000 per unit are now the norm. Many councils run "above benchmark" or "double benchmark" applications — when construction costs rise and rent cannot be raised to match, the answer is simply to ask for more grant.

The grant is the state covering the difference between what the asset cost to build and what it can ever earn back. Calling it a "grant" rather than a "loss provision" is a presentational choice, not an accounting one. The same money, written differently in the same set of books, would be a write-down on a corporate balance sheet large enough to attract a regulatory letter.

The rent is recycled tax

Even the £85,000 of "value" is mostly an accounting fiction. The standard valuation discounts the future rent stream — £106 a week for thirty years — to today's pounds. But the cash that funds that rent stream comes overwhelmingly from the taxpayer. The 2024-25 GOV.UK social housing lettings data shows that 83% of households in a new social letting received housing-related benefit — 57% via the Universal Credit housing element, and a further 26% via Housing Benefit. Two-thirds of the existing social tenant population are in the same position. Total UK spending on Housing Benefit plus the UC housing element now exceeds £20 billion a year, making Britain a clear outlier in the OECD — well above second-placed Finland and roughly double third-placed Germany.

The cashflow looks like this. The state taxes a worker. The state pays the worker's tax back to a Housing Revenue Account in the form of housing benefit. The Housing Revenue Account books the receipt as rent. The rent capitalises into £85,000 of asset value. The taxpayer paid the £200,000 build cost as a grant, and the taxpayer pays the rent that produces the £85,000 of value. The "value" is the taxpayer's own money making a return journey, with an accounting stop in between. The social housing provider is not making money. It is intercepting money on the way back to the pocket it came from, and keeping a small operating margin for management and major works.

The state builds a £200,000 asset, books it at £85,000, and pays the rent that produces the £85,000.

And then the regulatory bill arrives

Once the asset exists, the same regime that mandated it now sends the upgrade invoice. The Local Government Association's commissioned 2023 research by Savills put the capital cost of compliance on the existing English council housing stock at £8 billion for post-Grenfell building safety, £23 billion for Net Zero compliance, and £3.5 billion to lift every home to EPC rating C. The average Housing Revenue Account will need to find roughly £37,500 per home in regulatory upgrades alone, before a single tile is replaced on a routine repair. Most of this will be borrowed by councils, against future rents that, once again, are taxpayer-funded. A loss-making asset is being prepared to absorb further taxpayer-funded capital, to be serviced by further taxpayer-funded rent. As Pimlico Journal noted in June 2024, much of the apparent "surplus" sitting in Housing Revenue Accounts is the lull between the end of the original sixty-year-old borrowing payments and the start of the new regulatory bill. The surplus is illusory. The bill is real.

The policy regime, 1997 to now

This is not a market failure. It is the deliberate output of a policy regime that has run, with cosmetic adjustments, since 1997. Right to Buy — kept on by Blair — was the moment the state began selling off the asset side of the social housing balance sheet at a deep discount while continuing to fund the liability side via housing benefit. Brown's expansion of tax-credit and benefit-based housing support locked in the transfer from working taxpayer to renting recipient. The post-2010 governments preserved the architecture: the right-to-buy stock continued to be sold, the benefit bill continued to grow, new social housing continued to be built at a structural capital loss, Homes England continued to be topped up, and "affordable" housing requirements under Section 106 continued to socialise build costs onto private developers, who passed them on, in turn, to the buyers of the unaffordable homes next door.

Every government since 1997 has presided over a system that builds a £200,000 asset, books it at £85,000, and asks the taxpayer to pay both ends. The Conservative governments of the post-2010 period preserved the same architecture despite the rhetoric. The 2024 settlement looks indistinguishable from the 1997 one. The housing crisis was a choice. The benefit system pays out where it never paid in. Universal Credit underwrites the rent for the same employer pay packets the state already taxes. The social housing pipeline is the most expensive line in the same ledger.

Who is the casualty?

The casualty is not the social tenant. They receive lifetime exclusive use of an asset that would fetch £275,000 in the open market, and in most cases the rent is paid for them. The casualty is not the private landlord either — new-build social housing has been ring-fenced against buy-to-let conversion since 2024. The casualty is the working renter who is too high earning to qualify for social housing but cannot afford to buy in the open market, the same forgotten cohort that fell through the gap of every other 1997-present housing policy. They pay the tax that funds the build. They pay the tax that funds the rent. They cannot enter the asset that their taxes paid for. And they cannot afford an equivalent home in the market that the same policy regime has spent a quarter of a century distorting.

The "pocket lining" debate misses the structure entirely. There are no pockets being lined. There is no private profit at risk. There is no slush fund. There is, instead, a policy regime that takes £200,000 of taxpayer money, turns it into £85,000 of state-balance-sheet value, charges the taxpayer for the rent that produces the value, sends the regulatory upgrade bill back to the taxpayer for good measure — and then frames the whole thing as a gift to the people locked out of it.

Worth less than it cost. By design. Since 1997.
