New home approvals drop 21%: planning and viability signals for project teams
Reviewed by Tom Sullivan

First reported on The Construction Index
30 Second Briefing
New home planning approvals in England fell to 45,315 in Q2, the weakest quarter since 2012, with annual permissions at 214,515 – just 58% of the 370,000 units a year implied by the NPPF’s 300,000-home target. Permissions on larger sites over 10 units dropped 21% quarter-on-quarter to 39,689 homes, while approvals for private homes fell 19% over the same period and projects of three or more homes hit a record low of 1,234 in Q2. The Home Builders Federation cites weak mortgage-backed demand, rising construction costs and new taxes and levies as eroding development viability and is calling for a moratorium on further policy-driven costs.
Technical Brief
- Glenigan-derived HBF data show 214,515 permissions in year to Q2 2026, 8% down year-on-year.
- Annual permissions now sit 36% below the 2017 peak, indicating a sustained structural decline in pipeline.
- Larger schemes are most affected, with Q2 approvals on >10‑unit sites also 14% below Q2 2025.
- Very small sites of one or two units formed roughly 50% of all 11,764 projects approved in the year.
- HBF attributes reduced site investment to weak effective demand and restricted access to affordable mortgage lending.
- Rising construction input costs, new taxes, levies and policy requirements are cited as key viability constraints.
- Government’s First Homes scheme is expected by HBF to support buyer demand and partially re‑stimulate supply.
Our Take
Taken with the HBF’s earlier finding that Q1 private housing consents in England hit a 20‑year low, the year‑to‑Q2 2026 data suggest a structural rather than purely cyclical constraint on the UK housing pipeline, which contractors and consultants should factor into medium‑term workload planning.
The combination of a 21% quarter‑on‑quarter drop in approvals for sites over 10 units and HBF survey evidence that SME builders are curbing speculative starts points to particular pressure on larger, infrastructure‑heavy schemes, where planning risk and financing costs compound each other.
Our wider Policy coverage shows repeated friction around planning and implementation issues (including Biodiversity Net Gain and unspent Section 106 contributions), indicating that UK homebuilding constraints now sit as much in the regulatory and delivery system as in pure demand for new units.
