UK Construction Growth Masks Housing Crisis: Infrastructure Booms, Homes Lag

The British construction sector is staging a tentative recovery after a bruising year of consecutive monthly declines, but the £400bn industry's return to growth tells only part of the story. According to forecasts from McBains shared with City AM, the sector is expected to expand by 4.5 per cent in 2026, up from 3.5 per cent last year. The problem? Almost all of that growth will come from infrastructure projects in defence, transport and energy, whilst the housebuilding sector—where Britain's acute housing shortage demands urgent attention—remains mired in stagnation.

The disconnect couldn't be more awkward for a government that has staked considerable political capital on its commitment to build 1.5 million homes by the next general election. Infrastructure spending may flatter the headline figures, but it won't house young families locked out of homeownership or ease the pressure on Britain's overheated rental market.

Labour costs squeeze an already fragile sector

Rising employment costs have emerged as a particularly sharp thorn for developers. Minimum pay for 21 to 22-year-olds has jumped 33 per cent over the past three years, whilst rates for 18 to 20-year-olds have climbed 46 per cent, according to McBains managing director Clive Docwra. His concern is that these increases could discourage firms from taking on apprentices precisely when the construction workforce sits at record lows.

Labour's pledge to offer fully-funded training for under-25s in small and medium-sized businesses may soften the blow, but it doesn't address the fundamental cost pressures squeezing margins across the sector. The Chartered Institute of Building (CIOB) reports that whilst 66 per cent of young people hold positive views of construction work, fewer than 30 per cent would actually consider pursuing careers in the industry—a perception gap that no amount of government funding can bridge on its own.

Developers face a nasty pincer movement: rising input costs on one side, subdued demand constrained by high mortgage rates on the other.

What's particularly troubling is that tender price inflation, which measures the gap between initial quotes and final submitted bids, is forecast to accelerate from 2.75 per cent this year to 4 per cent by 2029. That means construction costs will continue outpacing general inflation, squeezing margins in an already price-sensitive housebuilding market. Developers face a nasty pincer movement: rising input costs on one side, subdued demand constrained by high mortgage rates on the other.

Planning delays and financing costs pile on pressure

High financing costs continue to suppress both commercial and residential construction activity. Planning delays compound the problem, extending project timelines and inflating costs further. The sector's struggles with housebuilding and commercial projects stand in stark contrast to infrastructure's relative strength, creating an increasingly bifurcated industry.

Colin McCaffrey, director at McBains, notes that whilst growth forecasts offer some reassurance, "recovery will be uneven, with sectors like housebuilding and commercial projects struggling for momentum." That unevenness matters enormously for policy delivery. Infrastructure projects—however welcome for economic productivity—don't solve the housing crisis that affects millions of British households.

The Office for Budget Responsibility has already cast doubt on whether Labour's 1.5 million home target is achievable, and these latest forecasts suggest that scepticism may be well-founded. The arithmetic is brutal: even with modest overall sector growth, if housebuilding remains flat or contracts whilst infrastructure booms, the government's flagship housing commitment becomes mathematically impossible to meet.

A workforce crisis amid record unemployment

The number of young people not in education, employment or training is approaching one million, prompting the CIOB to call for a government campaign to channel unemployed youth towards construction careers. David Barnes, the institute's head of policy and public affairs, says the sector is "crying out" for more young workers. The irony is palpable: Britain has both a housing shortage and nearly a million young people without work, yet can't seem to connect the two problems into a solution.

Britain has both a housing shortage and nearly a million young people without work, yet can't seem to connect the two problems into a solution.

The construction sector's emergence from a year-long contraction represents progress of sorts, but it's progress that largely bypasses the areas of greatest social need. Infrastructure investment in defence, transport and energy delivers important long-term benefits, yet does nothing to address the immediate housing affordability crisis facing young families and renters.

Whether Labour can bridge the gap between infrastructure-led growth and housing delivery will depend on factors largely outside the construction industry's control: planning reform implementation, mortgage rate trajectories, and whether workforce development initiatives can overcome both cost pressures and the sector's image problem among young workers. For the moment, the recovery in construction output looks increasingly like a statistical mirage that obscures more than it reveals about Britain's capacity to build the homes it desperately needs.
