Britain’s housing delivery machine is stalling at the worst possible moment. Net additional dwellings in England fell to 208,600 in 2024/25 — down 6% year-on-year GOV.UK and 16% below the 2019/20 peak — just as the Labour government needs output to accelerate sharply toward its 1.5 million homes target. Planning permissions have collapsed to 15-year lows, PBC Today completions are forecast to drop to around 160,000 in 2025/26 (the lowest since 2014/15), Savills and the Construction Products Association has downgraded its private housing output growth forecast for 2026 to just 1.5%. Buildersmerchantsjournal A convergence of viability pressures, skills shortages, regulatory costs, and weakening buyer demand means the sector enters 2026 facing what multiple industry bodies describe as the most difficult operating environment in over a decade.
The numbers tell a stark story of decline
England’s housing supply has now fallen for three consecutive years. BCIS The 208,600 net additional dwellings recorded in 2024/25 comprised 190,600 new-build completions (91%), 17,710 change-of-use conversions (8%), and smaller contributions from other sources, net of 4,630 demolitions. GOV.UK Early EPC-based estimates suggest 2025/26 is tracking even lower: approximately 158,700 homes were delivered in the first nine months to January 2026, GOV.UK putting the full year on course for roughly 204,000 homes BCIS — a further decline.
Quarterly data confirms the deterioration. UK-wide completions in Q3 2025 reached just 37,350, the lowest quarterly total since Q3 2014 and 27% below pre-pandemic levels. BCIS While housing starts have recovered modestly from their 2024 trough — reaching 29,620 in England in Q3 2025, up 3% year-on-year GOV.UK — this follows an artificially depressed base created when builders rushed to beat June 2023 building regulation changes. House of Commons Library Current starts remain 57% below the Q2 2023 peak. GOV.UK
NHBC registration data offers a partial counterpoint. Across the UK, 115,350 new homes were registered in 2025, up 11% on 2024, Mortgage Strategy with private sector registrations rising 12%. Timber Development UKPBC Today However, NHBC completions still fell 2% to 122,012, Timber Development UK +2 and registration volumes remain well below the pre-pandemic norm of 38,000–42,000 per quarter. Building NHBC corporate strategy director Daniel Pearce warned that “fragile consumer confidence, affordability challenges, and economic uncertainty continue to impact demand.” Timber Development UK +2
The planning pipeline has collapsed to crisis levels
Perhaps the most alarming leading indicator is the state of planning permissions. According to the HBF’s Housing Pipeline report (drawing on Glenigan data), just 42,000 new homes received planning permission in Q3 2025 — a 31% drop on Q3 2024 and the lowest quarterly total in over 15 years. Over the year to September 2025, permission was granted for only 209,781 homes, the lowest 12-month total since 2013, Construction Index representing just 57% of the combined NPPF annual target of 370,000. The number of housing sites permissioned has fallen for 11 successive quarters and now stands at just 36% of the level seen in 2018.
London has been hit hardest. Fewer than 34,000 units and only 910 projects were approved in the capital over 12 months — the lowest since HBF Pipeline records began. Building Safety Regulator (BSR) delays have compounded the problem: Osborne Clarke London housing registrations fell 27% Today’s Conveyancer in 2025, the only region to decline, PBC Today and London starts are running at just 2% of planning targets according to Arcadis analysis. Arcadis
The causes are structural, not cyclical. The HBF points to a deepening viability crisis driven by accumulated policy costs, new taxes, and levies. Zoopla analysis found half the country is economically unviable for new housing development. The imminent Landfill Tax doubling (April 2026) and new Building Safety Levy (from October 2026, adding approximately £15,000 per home) threaten to make conditions worse. HBF CEO Neil Jefferson warned: “Home builders continue to grapple with rising policy costs and new taxes, making investment hard to justify.” PBC Today
Labour’s 1.5 million homes target looks increasingly out of reach
Labour pledged to deliver 1.5 million new homes over the parliamentary term David Andrew starting July 2024, equating to 300,000 per year. The revised NPPF, published in December 2024, sets an even more ambitious combined local authority target of 370,000 homes annually. NALC Progress so far falls dramatically short. Between the parliament’s start on 9 July 2024 and 11 January 2026, an estimated 309,600 net additional homes were delivered GOV.UK — approximately 20.6% of the target in roughly 30% of the parliamentary term.
At the current annual rate of around 208,000, the government would need nearly six more years to reach 1.5 million. To catch up from this point, England alone would require approximately 339,000 homes per year for the remainder of the parliament — a rate never sustained in modern British history. The BCIS has stated bluntly: “The ship has long sailed on the government’s 1.5 million new homes target.” BCIS Savills estimates that even at unprecedented expansion rates, maximum achievable delivery would be approximately 1.2 million completions over five years. Savills The OBR’s most optimistic October 2025 forecast projects 1.49 million UK-wide (not just England) by 2029/30, though this is widely considered unrealistic.
Housing Minister Matthew Pennycook has acknowledged progress is “slow” while insisting delivery will “ramp up” over the parliament. Transport Secretary Heidi Alexander made clear that “it’s not going to be the case that you just divide 1.5 by the five years.” Housing Secretary Steve Reed, who replaced Angela Rayner in September 2025, has adopted a “build, baby, build” mantra Local Government Chronicle but faces the same structural constraints.
A perfect storm of headwinds batters the sector
Skills and labour shortages remain critical
The CITB’s Construction Workforce Outlook projects a need for 47,860 additional construction workers per year — 293,300 over five years — to meet projected demand. James Hallam Construction employment has declined 10.8% since the pandemic, Tokio Marine HCCTurnerandtownsend with nearly 22% of the remaining workforce aged over 50. Apprenticeship starts have dropped 30% over the past decade, and only 19% of parents would encourage their child into a construction career. The government’s £625 million skills investment aims to create 60,000 specialist workers, GOV.UK but this covers less than 25% of the identified gap. James Hallam Electrician wages have risen 7% in 2024 and 5% in 2025, reflecting acute shortages in specialist trades.
Building costs are re-accelerating
Construction material prices for all work rose 3.3% in the year to December 2025, with new housing materials specifically up 4.2% — marking the 12th consecutive month of increasing annual movement. Ready-mixed concrete deliveries in 2025 hit 11 million cubic metres, the lowest on record, BCIS while concrete block deliveries fell 17.3% annually. The BCIS General Building Cost Index showed annual inflation of 4.4% in October 2025, exceeding CPI. Forward forecasts project building costs rising 14% over five years to mid-2030, with tender prices up 15%.
Mortgage market and affordability constraints
The Bank of England base rate stands at 3.75% money.co.uk following gradual cuts from 5.25%, but mortgage rates remain elevated at around 4–5% for typical fixed deals. Mortgage approvals have weakened: falling from 65,119 per month on average in 2025 to just 59,999 in January 2026, the lowest since January 2024. Housing demand is 12% lower year-on-year, with new sales agreed down 9%. First-time buyer affordability has been further squeezed by the reduction in stamp duty thresholds from £425,000 to £300,000 in April 2025.
Developer viability under acute pressure
The Section 106 system is in crisis. Approximately 8,500 affordable homes under construction or due to commence are not under contract with a Registered Provider, with more than 700 sites delayed in the past three years. RPs face constrained financial capacity from higher finance costs, rising build costs, building safety remediation obligations, and decarbonisation commitments. UK Parliament The BSR’s Gateway 2 approval process has created severe bottlenecks: RICS only 338 of 2,108 applications (16%) were approved between October 2023 and March 2025, Construction Management with approximately 10,000 London homes awaiting approval for over six months. Some 1,300 completed flats in London stand empty, unable to obtain BSR sign-off. The second staircase requirement for buildings over 18 metres (effective September 2026) is estimated to reduce saleable floor area by 5–10% and increase build costs by 6–13%.
Nutrient neutrality requirements continue to block an estimated 160,000+ homes across 74 local authority areas, despite new housing accounting for less than 1% of total nutrient pollution. Resolution may not come until 2030.
Major housebuilders show resilience but face margin pressure
The listed housebuilders are delivering modest volume growth but face a common theme of margin compression heading into 2026.
Barratt Redrow, now the UK’s largest builder following its 2024 merger, completed 7,444 homes in H1 FY26 (up 4.7%) Investing.com and guides for 17,200–17,800 for the full year. Forward sales stood at £3.4 billion (11,168 homes). CEO David Thomas described a “subdued trading environment” with “low consumer confidence.” Investegate The firm expects build cost inflation of approximately 2% and is targeting £400–500 million net cash by year-end.
Taylor Wimpey completed 11,229 homes in FY2025 (up 6%), with revenue of approximately £3.8 billion. However, operating margin has slipped to around 11% from 12.2%, and management warned of further margin pressure in 2026 due to a lower opening order book and softer pricing on bulk deals. Construction Enquirer CEO Jennie Daly noted “affordability is slowly improving” but demand remains “muted — particularly among first-time buyers.”
Persimmon stands out as the sector’s strongest growth story, with 11,905 completions in 2025 (up 12%), ahead of expectations. Persimmon Homes Underlying pre-tax profit is expected at the upper end of the £415–440 million range, Hargreaves Lansdown supported by vertical integration savings of approximately £5,000 per plot. CEO Dean Finch expects “another year of solid growth” in 2026, with consensus pointing to 12,043 completions and PBT of £461–487 million.
Berkeley Group maintains the sector’s highest operating margins at 20.1%, with FY25 pre-tax profit of £529 million. Its London and South-East brownfield focus faces specific headwinds from BSR delays and subdued international buyer demand. The company guides £450 million PBT for FY26 and “a similar level” for FY27.
Vistry Group remains the sector’s highest-risk name. After three successive profit warnings in late 2024 relating to understated build costs (total impact approximately £165 million), Construction Wave FY2025 adjusted PBT came in at £268.8 million on 15,658 completions (down 9%). Shares fell over 17% on 5 March 2026 after management warned of lower margins in 2026 despite expected volume growth. Investing.com CEO Greg Fitzgerald, who is stepping down by March 2027, positioned the partnerships-focused model as well-suited to capture the £39 billion SAHP programme.
Bellway delivered solid FY25 results (8,749 completions, up 14%; underlying PBT up 28% to £289 million) Investegate and targets approximately 9,200 completions in FY26 UK Investor Magazine at an 11% margin. CEO Jason Honeyman called for “essential financial support for first-time buyers” alongside planning reform.
Sector valuations remain depressed. Housebuilders have underperformed the FTSE 100, with five-year share price declines of 56% for Persimmon and 25% for Barratt Redrow. Morningstar considers all major housebuilders undervalued, with Persimmon its top pick.
Policy reforms are ambitious but slow to deliver
The government has pursued an extensive legislative programme. The revised NPPF (December 2024) restored mandatory housing targets, NALC introduced the grey belt concept for Green Belt land, strengthened the brownfield-first approach, GOV.UK reinstated five-year housing land supply requirements, GOV.UK and set a combined annual target of 370,000 Urbanist Architecture homes using a new standard method based on 0.8% of existing housing stock with an affordability adjustment.
The Planning and Infrastructure Act 2025 (Royal Assent 18 December 2025) Propertymark introduced spatial development strategies, GOV.UK a nature restoration fund, mandatory planning committee training, Pinsent Masons cost recovery for planning fees, and streamlined infrastructure consent processes. NALC A further NPPF consultation published in December 2025 — described as the “most significant update since the NPPF’s introduction in 2012” — proposes Nockolds a permanent presumption in favour of suitably located development, a “default yes” to building around train stations, and streamlined biodiversity net gain requirements.
The New Towns Taskforce, led by Sir Michael Lyons, recommended 12 locations in September 2025 GOV.UK with a collective target of approximately 300,000 homes. Three priority sites — Tempsford, Crews Hill, and Leeds South Bank — are targeted for construction before the next election.
The most significant investment commitment is the £39 billion Social and Affordable Homes Programme (SAHP) 2026–2036, announced at the June 2025 Spending Review. This is the largest long-term affordable housing investment in recent memory, GOV.UK targeting 300,000 affordable homes with at least 60% for social rent. GOV.UK Bidding opened in February 2026. National Housing Federation Complementary measures include a 10-year CPI+1% rent settlement for social housing (providing long-term certainty for registered providers), GOV.UK £2.5 billion in low-interest loans UK Parliament via a new National Housing Bank National Housing Federation launching in March 2026, GOV.UK and £600 million for construction skills training.
However, planning department capacity remains a critical bottleneck. 82% of council planning departments report staff shortages, with an estimated national gap of 2,200– 7,500 planners. Average graduate planner salary in local government sits at approximately £26,000, making recruitment difficult. The Planner The government’s pledge of 300 new graduate and apprentice planning officers GOV.UK covers only around 15% of the shortfall.
Regional divergence reveals a tale of multiple housing markets
Performance varies dramatically across the UK nations and English regions. The West Midlands (+29%) and Eastern England (+24%) led NHBC registration growth in 2025, while London declined 27% — the only region to fall. London’s crisis reflects the compound effect of BSR delays, stretched affordability, reduced affordable housing thresholds PBC Today (cut from 35% to 20% to stimulate delivery), and a 93% drop in BTR starts between 2022 and 2025.
Scotland completed 18,347 homes in the year to September 2025, gov.scot down 8%, with social completions falling 15%. Social housing starts hit their lowest level since data collection began in 1997. gov.scot Despite building more homes per 10,000 population (35) than England (33), 11 local authorities are behind targets, with Edinburgh City facing a 39% shortfall. Savills Rent controls drove a 65% decline in BTR starts between 2022 and 2025, though recent legislative exemptions for BTR may reopen investment.
Wales faces perhaps the steepest challenge proportionally. Just 4,756 new dwellings were built in 2023/24 against a 7,400 annual target, and completions fell 9% in the year to June 2025 to their lowest in over a decade. Planning consents in Q2 2025 were 67% below Q2 2024. One bright spot: a record 3,643 affordable homes were delivered in 2024/25, gov.wales and the Welsh Government has invested over £2 billion in social housing.
Northern Ireland saw completions fall 15% year-on-year in Q3 2025, with social housing completions down 70%. Insufficient wastewater infrastructure capacity has created what the Chartered Institute of Housing called an “unacceptable bottleneck.”
Genuine tailwinds exist amid the headwinds
Despite the challenging outlook, several factors could support recovery through 2026 and beyond.
Build to Rent investment hit a record £5.3 billion in 2025 (Savills), with Q4 alone reaching £2.7 billion — the highest single quarter ever. Savills Single-family housing now accounts for 59% of BTR investment, up from 47% in 2023. The sector has 146,700 completed homes, 49,000 under construction, and 110,000 in the planning pipeline. CBRE anticipates continued momentum in 2026.
Affordable housing delivery reached 64,762 completions in 2024/25, the highest since 2014/15, GOV.UK with social rent completions at their highest since 2013/14. GOV.UK Local authority delivery hit its highest recorded share (16%) since records began in 1991/92. The £39 billion SAHP, combined with the CPI+1% rent settlement and National Housing Bank, provides an unprecedented funding framework for the affordable sector.
Modern Methods of Construction continue to mature, with the government expecting at least 25% of new homes to use MMC. CITB estimates modular construction can reduce costs by up to 20% Uk and deliver projects 30–50% faster. Builder Expert Bellway has invested in a timber-frame facility targeting 30% of its output by 2030. However, high-profile failures among modular companies and regulatory frameworks still geared toward traditional construction temper expectations.
Brownfield land in England can accommodate a minimum of 1.41 million homes according to CPRE, with brownfield sites increasing 54% since 2018. CPRE Multiple funding programmes — including the £150 million Brownfield Housing Fund, Homes England’s Brownfield, Infrastructure and Land Fund, and strengthened NPPF brownfield provisions — support this pipeline.
Mortgage affordability is gradually improving through a combination of falling rates (base rate now 3.75%), Raisin wage growth outpacing house price growth for the first time in years, and a first-time buyer share of purchases above the long-run average. If the Bank of England continues its cutting cycle — the OECD suggests rates could reach 3.5% by Q2 2026 — this should support demand through the year.
Conclusion: reform is necessary but not yet sufficient
The UK housebuilding sector enters 2026 caught between ambitious government reform and stubborn ground-level constraints. The policy architecture is more supportive than at any point in a generation: mandatory housing targets restored, £39 billion committed to affordable housing, a new planning act on the statute book, and grey belt release mechanisms established. Petitions These are not trivial achievements.
But the data demands honesty. Completions are falling, not rising. The planning pipeline has contracted to levels not seen since the early 2010s. Skills shortages, building safety costs, and the S106 crisis are not problems that legislation alone can solve. The CPA’s successive forecast downgrades — from 8% private housing growth predicted in autumn 2024 to just 1.5% for 2026 — capture how reality has repeatedly disappointed optimism.
Three factors will determine whether 2026 marks a trough or the start of a deeper decline. First, whether mortgage rates fall enough to meaningfully stimulate buyer demand — UBS estimates a 75 basis-point swap rate decline is needed to restore average affordability ratios. II Second, whether the government addresses the viability crisis by deferring or moderating new cost burdens like the Building Safety Levy. Third, whether local authority planning capacity can be expanded fast enough to translate NPPF reforms into actual permissions. The houses the UK urgently needs will not be built by targets or legislation alone. They require commercially viable projects, a workforce to deliver them, and buyers or investors willing to pay for them. RIBA In 2026, all three remain under strain.
