IN Brief:
- Recent surveys from HBF, CIOB, and FMB show smaller developers remain cautious about starts, land buying, labour, and viability.
- Planning delays, higher material and wage costs, utility-connection hold-ups, and thin supply-chain resilience are combining into a structural problem rather than a passing market wobble.
- If government wants more output from SME builders, it will need a system that rewards delivery at small scale instead of punishing it with delay, uncertainty, and cost drift.
Every government that talks seriously about boosting housing supply eventually rediscovers the same argument: Britain needs a stronger base of small and medium-sized builders. The case is easy enough to make. Smaller developers can work on sites the majors will ignore, build into towns and suburbs where volume players are more selective, and widen the supply base in a market that has become heavily concentrated. That part of the diagnosis is sound. The more awkward part is that the commercial environment still looks far better at explaining SME caution than SME expansion.
The latest HBF survey makes the point plainly. Seven in ten SME developers said current market conditions were causing caution around starting new sites, including nearly a quarter who said conditions were causing significant caution or delaying starts altogether. Among builders delivering between one and 75 homes a year, more than a quarter expected housing starts to decline over the next three months, with 18% anticipating a significant reduction. That is not the profile of a segment gearing up to transform national delivery. It is the profile of one still deciding where risk has become too expensive to carry.
That caution is often misread as sentiment, as though smaller builders merely need a confidence boost. In practice it looks more rational than emotional. The same HBF research found that 76% of respondents ranked planning delays among their top three supply-side constraints, while 57% cited viability pressures, 42% cited the cost and availability of land, 38% pointed to regulatory and taxation burden, and 22% highlighted delays to utility connections. Each of those constraints is damaging on its own. In combination, they create exactly the kind of uncertainty that forces smaller operators to ration land purchases, slow starts, and protect cash.
Small sites, thin margins, rising friction
What makes this more than a routine cyclical slowdown is the way several pressures are now landing at once. The latest State of Trade findings published by CIOB, drawing on work with FMB, found that 57% of construction SMEs reported rising wages and 75% raised concerns about higher material costs. More than two in five said they had changed contractors during the period, with nearly a quarter of those changes driven by insolvencies or firms going bust. Those figures are useful because they show the pressure points in live operation: not just cost inflation in the abstract, but cost inflation colliding with labour scarcity and a thinner, less reliable supply chain.
There is still work in the market. The same CIOB release noted positive readings for workloads, employment, and enquiries in the second half of 2025. Yet activity in positive territory does not automatically translate into healthy growth, especially for businesses without the balance sheet strength to absorb delay or reprice risk over a long pipeline. A listed national developer can spread pressure across geographies, tenure mixes, and capital structures. A smaller regional builder, working a short land bank and a narrower subcontractor network, has far less room to absorb a stalled planning decision, a utility delay, or a late-stage viability squeeze.
The FMB Small House Builders’ Survey 2025 sharpens the point. Nearly half of respondents cited the planning system as their biggest barrier, 41% pointed to material costs, and two-thirds said sites of interest were unviable because of expected Section 106 or Community Infrastructure Levy obligations. A striking 91% said building homes had become more expensive over the previous year. That is the sort of data that strips the romance from small-site delivery. Britain may like the idea of locally rooted builders bringing neglected plots forward, but viability is still what determines whether a site becomes a scheme or a file on a shelf.
The latest government building-materials commentary reinforces that sense of uneven pressure rather than uniform relief. It showed annual price increases to February 2026 of 7.6% for imported sawn or planed wood and 7.3% for gravel, sand, clays, and kaolin, even as some other product categories softened. For SME builders, that sort of market is especially awkward. The headline may not be a universal surge across every material line, but the practical effect is still a planning and procurement headache. It becomes harder to lock in margins, harder to price confidently, and harder to convince lenders, landowners, or joint-venture partners that the scheme in front of them will still stack up once it reaches site.
The system still rewards scale
Planning remains the most persistent drag because it does more than delay a start date. For smaller builders, time in planning becomes cost in almost every other part of the model. Consultant fees accumulate, financing becomes harder to secure on favourable terms, land options lose their neatness, subcontractor availability changes, and policy requirements can shift while a scheme is still waiting for determination. When 76% of respondents in the latest HBF survey put planning delays among their top constraints, they are not describing a paperwork irritation. They are describing a mechanism that steadily erodes certainty.
The drag continues beyond permission. Utility delays are often treated as secondary in policy debate, yet they matter disproportionately on smaller sites, where the programme is less able to absorb dead time and the developer has fewer parallel projects to spread overhead across. The same applies to labour. The FMB survey found that 53% of respondents struggled to hire enough site-based staff, even though 69% planned to grow their workforce in the coming year. Ambition is still present, then, but it is running into the practical limits of recruitment, training, and retention. When a site cannot secure the right bricklayer, groundworker, or carpenter at the right time, the supposed agility of a small builder starts to look rather fragile.
That fragility is heightened by a broader insolvency backdrop that still feels uncomfortable. The latest company insolvency statistics show 1,878 registered company insolvencies in England and Wales in February 2026, up 7% on January. Construction is not uniquely exposed to that national figure, but SME builders experience insolvency differently from larger clients. A subcontractor failure on a small scheme is not merely inconvenient. It can disrupt programme logic, force a costly reshuffle, and turn already-thin margins into a negotiating exercise with reality.
All of this leaves policy with an obvious contradiction. Ministers continue to talk about speeding delivery, widening the builder base, and unlocking more local housing. The market conditions facing smaller builders still reward the opposite instincts: caution over expansion, shorter commitments over longer pipelines, and survival over growth. That is not because SME developers lack demand or appetite. It is because too many parts of the current system still treat time, certainty, and scale as though they were evenly distributed. They are not.
If Britain wants smaller builders to do more heavy lifting in housing delivery, the answer will not be found in warm words about diversification alone. It will require a planning and delivery environment in which delay does not destroy viability, utility connections do not become a hidden programme tax, and labour shortages do not turn every growth plan into a gamble. Until then, the country will keep asking SME builders to solve a delivery problem while leaving intact many of the conditions that make expansion feel like the risky option.
