In 1988, small and medium-sized housebuilders delivered 39% of new homes in England. By 2020, their share had fallen to 10%. The precise definition of an SME varies between datasets — some historic measures focus on builders producing fewer than 100 homes a year, while current government and industry programmes use different thresholds — but the direction of travel is not seriously disputed. England has lost a large part of the small and mid-sized housebuilding sector that once sat between the one-site local builder and the national volume developer. Lichfields — Small builders, big burdens
That matters because housing supply is not determined only by how many homes receive planning permission or how much land is allocated. It also depends on how many businesses are capable of turning different types of land into homes at the same time.
A housing market dominated by a smaller number of large developers can deliver major sites, infrastructure and substantial volumes. What it cannot necessarily do is substitute completely for hundreds or thousands of smaller builders developing five, ten, twenty or fifty homes on sites that require a very different business model.
The issue is therefore not simply whether small housebuilders deserve a larger share of the market. It is whether England has lost part of the machinery through which smaller sites become homes — and through which a local builder capable of delivering five or ten homes develops into a regional company building fifty or a hundred.
How concentrated the market has become
Lichfields records SME housebuilders’ share of English housing output falling from 39% in 1988 to 10% in 2020. It also identifies a parallel problem in the land pipeline: Local Plans have been allocating fewer of the small and medium-sized sites on which these businesses disproportionately depend.
There are still thousands of smaller housebuilders, but care is needed when comparing numbers from different studies. The Competition and Markets Authority’s housebuilding market study, for example, defined an SME unusually broadly as any builder producing 1,000 homes or fewer a year. On that definition, it estimated that thousands of SMEs across Great Britain collectively built more than 50,000 homes annually, while the largest 11 housebuilders supplied around 40% of the market in 2021–22. Competition and Markets Authority — Housebuilding market study final report
That does not mean the large housebuilders have somehow failed. They are capable of taking on things many smaller firms cannot: major strategic sites, expensive infrastructure, long build programmes, remediation and the financial exposure involved in holding large land and work-in-progress positions.
The problem is that the two models are not interchangeable.
Why this matters for supply, not just industry diversity
Large speculative housebuilders generally do not build every permitted home on a major site as quickly as physical construction capacity allows and then hope purchasers appear. The CMA found substantial evidence that build-out tends to reflect the local absorption rate — the pace at which new homes can be sold without requiring material reductions in price.
That should not be confused with a simplistic claim that large developers deliberately refuse to build. Completed but unsold homes tie up capital too. The point is that hundreds of homes on one large site are still being sold into a particular local market, at particular price points, over time.
A more diverse housebuilding sector can increase capacity in another way: more builders operating across more sites, selling different homes in different places into separate pools of demand at the same time.
That is where smaller builders matter.
A national developer capable of delivering a 3,000-home urban extension is not necessarily interested in a 17-home infill site, a former commercial yard or a modest edge-of-settlement parcel requiring a bespoke planning and construction approach. For a local or regional builder, those sites can be the core business.
Smaller sites can also move through their total build programme faster than major developments because there are fewer homes to absorb locally, although aggregate buyer demand still places a limit on how much private housing any area can support at once.
So the argument for SMEs does not depend on claiming that restoring their 1988 market share would mechanically create tens of thousands of extra homes. More builders still need viable land, permissions, finance, labour and buyers.
The stronger point is structural: England has substantially fewer businesses capable of taking smaller sites from acquisition through planning, finance, construction and sale. Rebuilding that capacity would increase the number and range of sites capable of being developed simultaneously.
Why the jump from small to mid-sized is so difficult
Part of the problem is not simply that small builders disappear. It is how difficult it can be for a builder completing five or ten homes to become a business delivering fifty or a hundred.
That transition requires more than finding another piece of land. The developer has to carry more land, finance several projects at once, employ or coordinate a larger workforce and survive delays or slow sales on one scheme without the whole business running short of cash.
Development finance and trapped equity. A small housebuilder can have a profitable first development and still be unable to fund the second. Equity invested in land and construction may remain tied up until the final homes are sold, while the next suitable site often needs to be acquired before somebody else buys it.
That creates a structural growth problem. Waiting for Site A to finish before buying Site B can keep the company operating on one site indefinitely. Buying Site B while Site A is still being built or sold requires more capital, a larger facility or a lender willing to finance growth across projects.
The National Housing Bank’s current smaller-housebuilder products have been designed explicitly around this problem. Finance is available from £250,000, with maximum loan-to-cost of up to 90% and a typical level around 80%. More significantly, its Accelerator Loan can provide development finance for an initial site while creating headroom to fund 100% of the land purchase for a follow-on scheme. National Housing Bank — Support for smaller housebuilders
That goes to the heart of the scaling problem. The obstacle is not necessarily whether Site A makes a profit. It is whether the developer can keep Site A moving while securing Site B early enough to avoid returning to zero once the first project is complete.
Land and planning risk. Smaller builders depend heavily on sites large enough to support a viable development but small enough to suit their operating model. The difficulty is not merely that bigger businesses can outbid them. A site has to be available, capable of securing permission and still viable after infrastructure, planning obligations, finance, build costs and tax.
Lichfields’ comparison illustrates how the planning burden has changed. Its research put the time required to obtain outline permission at around 13–14 weeks in 1990 compared with roughly 52 weeks in its modern sample. The inflation-adjusted cost of assembling supporting evidence rose from about £28,000 to around £125,000, while applicants were being advised to submit an average of around 30 separate assessments.
A £125,000 pre-permission burden is not the same commercial problem on ten homes as it is on two hundred.
Planning policy now recognises that distinction more clearly. The National Planning Policy Framework defines medium development as housing schemes of 10 to 49 homes inclusive on sites of up to 2.5 hectares — a sub-category specifically relevant to the scale at which many SME builders operate. MHCLG — National Planning Policy Framework, Annex B: Glossary
A separate national scheme governing which planning applications are decided by officers comes into force on 31 October 2026. Qualifying residential proposals of one to nine homes on sites smaller than 0.5 hectares must normally be delegated to officers, while larger applications fall under a different regime where the presumption is still delegation but referral to committee is possible when statutory significance tests are met. MHCLG — National Scheme of Delegation of Planning Functions
Those reforms may reduce some procedural friction, but they do not make an uneconomic development viable or remove the upfront cost and uncertainty involved in obtaining permission.
Section 106 and other viability costs. Planning permission is only useful if the development still works financially once its obligations and other costs are accounted for.
That has become particularly visible where registered providers have pulled back from acquiring some Section 106 affordable homes. For a smaller developer, an affordable-housing package that cannot be transferred can leave a large proportion of the development’s capital trapped relative to the size of the business.
Property Front Page examines that market failure separately in Why Developers Are Struggling to Sell Section 106 Affordable Homes — and What Happens Next.
Another cost pressure arrived on 1 October 2026, when the Building Safety Levy came into force in England for relevant residential development entering the building-control system from that date. Building Safety Levy regulations
The latest HBF and Quantum Development Finance sentiment survey illustrates the industry’s concern. Around nine in ten respondents said they believed the levy would make some developments unviable, while 36% said they had already delayed, redesigned or cancelled projects in anticipation of it. Those figures describe the views of the surveyed developers rather than proving that the levy itself will make nine in ten schemes unviable, but they show how strongly additional development costs can influence investment decisions at the smaller end of the market.
Skills and operating capacity. Smaller developers face the same shortages of experienced trades and site-management expertise as the wider construction industry but have fewer ways to spread the impact. A national business can shift labour between projects, run substantial training programmes and use group procurement. A small developer may depend on a comparatively narrow network of subcontractors and trades.
As a business grows, the challenge also changes. It needs not simply more bricklayers or carpenters but stronger project management, commercial control, land acquisition and finance functions. Scaling a housebuilder is therefore partly a management-capacity problem as well as a funding problem.
Sales risk concentration. A large developer can have multiple active outlets across different regions and price bands. A small builder may have one or two.
If sales slow on a single SME scheme, there may be nowhere else in the business to compensate.
That vulnerability is visible in the latest HBF/QDF SME Developer Sentiment Survey, conducted in July and published in August 2026. Development viability was cited by 75% of respondents as a major supply-side constraint and planning delays by 68%. On the demand side, 74% cited low buyer confidence and 70% wider housing-market conditions. More than half expected to buy less land during the following three months, producing a net land-purchase balance of -39%, compared with +5% in the first quarter. The corresponding balance for expected housing starts was -28%. HBF/QDF — SME Developer Sentiment Survey, August 2026
That survey covered 114 developers across England and Wales, ranging from businesses delivering a handful of homes to several hundred a year, so it should not be treated as a census of English SME housebuilding. But it shows how quickly future development decisions can move when land, planning, finance, build costs and sales risk are concentrated in a relatively small number of live schemes.
What’s being done, and how far it goes
Government support for smaller housebuilders looks materially different in late 2026 from the position only a year earlier.
The National Housing Bank is the most direct current intervention because its product design goes beyond simply making another pot of development finance available. Products such as the Accelerator Loan are aimed at the specific transition from one-site developer to multi-site business.
That is the right problem to target. A small builder does not become a serious regional competitor merely because one development is profitable. It becomes one when it can secure its next site before finishing the last, build a track record with lenders, spread risk across more than one project and retain enough capital to repeat the process.
Government-backed private lending is also continuing to expand. On 6 October 2026, the British Business Bank increased its ENABLE Build guarantee facility with Shawbrook from £150 million to £350 million. The facility supports development finance and bridging lending to smaller housebuilders across the UK. Around £240 million of lending included in the existing transaction had supported roughly 1,200 homes between December 2024 and June 2026, and the enlarged facility is expected to encompass around £700 million of lending over its lifetime. British Business Bank — ENABLE Build facility with Shawbrook increased to £350m
Planning policy is also beginning to distinguish more clearly between very small, medium and major housing schemes rather than treating everything beyond nine homes as essentially the same proposition.
But support on one side is arriving alongside difficult economics on the other. The Building Safety Levy is now live. Section 106 disposal problems continue on some schemes. Surveyed SME builders still identify viability and planning as dominant constraints, while weak buyer confidence affects the sales rates on which development appraisals ultimately depend.
That is why no single loan product, guarantee or planning reform can reverse a decades-long change in industry structure by itself.
Finance can allow a competent developer to acquire the next site, but it cannot make an uneconomic development viable. Faster planning can reduce delay and holding costs, but it cannot create buyer demand. More proportionate rules for medium-sized sites may remove unnecessary friction, but they do not automatically create more viable land. And none of those interventions guarantees that a business building ten homes today survives the next downturn and becomes the fifty-home builder of tomorrow.
The deeper issue is whether England can rebuild the ladder of housebuilding businesses that used to sit beneath the national volume developers.
Large housebuilders remain essential. They can deliver strategic sites, substantial infrastructure and housing volumes that smaller firms cannot realistically replicate. But an industry dominated by large sites and large balance sheets leaves part of the land market without the type of builder best suited to it.
The decline of smaller housebuilders therefore matters for more than competition or the fortunes of individual firms. England has lost part of the mechanism through which small sites become homes — and, just as importantly, part of the mechanism through which a local five-home builder develops into a regional company capable of delivering fifty, a hundred or more.
Reversing that decline will not come from recreating the housebuilding industry of 1988 by decree. It depends on whether enough capable businesses can obtain viable land, survive planning, finance more than one scheme at a time, absorb new regulatory costs and sell homes quickly enough to keep their capital moving.
If they cannot, England can allocate more land and grant more permissions while still lacking enough independent builders to turn that pipeline into completed homes at the pace policymakers expect.
