Amid a climate of fiscal caution, Rachel Reeves has made a rare pledge to increase spending — with an additional £2 billion offered for affordable housing projects. The Chancellor is being pushed in this direction by several economic winds: the private sector is struggling to deliver the numbers she needs to get close to the Government’s much-vaunted target of 1.5 million homes, and affordable housing numbers have dropped sharply due to the investment pressures facing the councils and housing associations which build them.

But while £2 billion is better than a cut, it also isn’t nearly enough to move Labour towards its target or to make a dent in the housing crisis which remains Britain’s most pressing domestic policy challenge.

This is because of choices made over several decades. The last five-year period in which England built 1.5 million homes ended in 1972. In 1970, in the middle of this boom, private-sector builders turned out 153,440 homes — not far off the 144,910 they turned out in 2022. But this 1970 figure was complemented by 130,180 homes built by England’s local authorities, and by 2022 this figure had collapsed to just 2,360 after decades of disinvestment by Government and sell-offs under the Right to Buy.

If Labour is serious about hitting its magic number of 1.5 million, then, it must find a way to turn the taps of public-sector housebuilding back on. Unfortunately, Reeves’s latest announcement will only release a few drips.

The Government’s mistake is its fixation on the idea that there is a huge, pent-up volume of private homes which will be released as soon as it stops local authorities asking for bat surveys and newt counts.  The real problem, however, is more fundamental. Most British homes are built by the “Big Six” volume house builders, through a model of “speculative” development — where large sums are paid for land up front, and homes are drip-fed out over a number of years to maintain profitability. As the Competition and Markets Authority (CMA) said last year, this “has seen the gap widen considerably between what the market will deliver and what communities need”.

Labour’s planning reforms won’t change this, as the number of homes built will stay roughly the same. What is needed instead is different housebuilding models and — in particular — social housing, which can be built en masse so long as the necessary funding is in place. Reeves’s latest cash boost, which will fund 18,000 homes, is the third injection of money into affordable housing since Labour took power in July, and shows she is serious about the issue despite her fiscal caution elsewhere.

But the money will not go very far. A combination of vast investment requirements and rising costs means that the councils and housing associations which would typically build the affordable homes are financially crippled at present.

The rate Reeves is offering (roughly £110,000 per home) is considerably more generous than what her Conservative predecessors were willing to offer, but it will still require the providers to put in tens or hundreds of thousands pounds to make the sums stack up. What’s more, 18,000 is a very small percentage of the 150,000 homes needed per year to bridge the gap between the Government’s target and the private market’s output.

The Treasury says this extra money is a taste of what is to come, with longer-term affordable housing funding to be set out in the Spending Review in the summer. If the Government is intent on meeting its target, its ambitions need to grow substantially by then. More social housing is the only way to make a meaningful difference to the way people in Britain experience the housing crisis — and not just for those who need a social home. When social housing is widely available, pressure is taken off private renting, which in turn dampens the appetite of private landlords to buy up existing homes. As a result, it’s easier for first-time buyers to purchase a home.

It is also a better route to growth than fiddling about with quangos and arguing over airport expansions. Last week, 40 economists, including four Nobel Laureates, wrote an open letter to the Chancellor asking her to significantly increase the level of investment in social housing.

There are levers Reeves can pull other than cash. The Treasury could release public land for free to social housing schemes, or set aside longer-term funding. But if she wants to make a difference, she will have to become more ambitious.
