November 2025: Monthly briefing on property development and housing delivery

November 2025 marks the month housing stopped being theoretical and became transactional.

The Autumn Budget makes a blunt offer: faster planning in exchange for higher taxes and tougher viability. It is backed by real resources, including a commitment to recruit 350 new planners, alongside wider recruitment across environmental regulators and other planning roles.

Alongside that, the “default yes” for homes near train stations makes the delivery model explicit. Build more, build faster, and build where infrastructure already exists.

But policy intent is only as good as delivery on the ground. Even with the new NPPF signalling a more pro-delivery stance, London boroughs and authorities nationwide remain stuck in old patterns, and inconsistent local interpretation is still doing the most damage.

Grey Belt is one example. Sites that meet the new tests are being treated as standard Green Belt, pushing schemes into avoidable appeals. If national policy is not applied consistently at local level, the same defensive reflex will blunt station-led delivery too.

Even if consistency improves, it will not solve the second constraint. Viability is now stopping schemes before consent and after it, with too many permissions sitting idle because the numbers no longer work.

That is why London has moved first. London’s housing emergency package is designed to unlock stalled schemes through time-limited reliefs and a faster route for developments that are genuinely ready to start. Yet the same capacity problem remains. Without planning departments that can process applications properly, the package risks creating hope first, then delay.

The OBR’s projections show why this sequencing matters. Net additions fall to 215,000 in 2026–27 before recovering to 305,000 in 2029–30, effectively betting on planning reform to lift delivery by around 30%. That mid-period trough is where confidence wobbles, finance tightens, and strategies fail.

At the same time, landlord taxation tightens the rental market’s underlying economics from April 2027. Higher tax on rental income compresses post-tax yields, and the responses are predictable: rents rise where the market allows, portfolios are sold where they cannot, and house-to-flat conversions reappear where the planning strategy stacks up.

So the tension is structural, not rhetorical. Tax changes bite before delivery improvements materialise, and the industry is being asked to accelerate while the system is still retooling. More planners, faster decisions, and reset incentives now have to overcome local inconsistency and viability constraints in parallel.
