The 2025 Autumn Budget has delivered a mix of infrastructure commitments, planning system reforms and skills funding, but alongside persistent cost pressures for construction businesses. The overall outcome is mixed: some medium-term pipeline clarity, but little relief for inflationary cost pressures or immediate sector-wide growth.
Key Budget Measures & What They Mean for Construction / Built Environment
BCIS / Sector Assessment — How This Lines Up with Prior Expectations
Using the Red-Amber-Green framework, where Red = no meaningful progress, Amber = some movement but insufficient detail, and Green = a positive or meaningful step forward:
Building Safety Act Implementation
The Autumn Budget did not introduce new measures to accelerate the Building Safety Act regime, but it sits against a backdrop of operational changes within the Building Safety Regulator (BSR) intended to improve the approval process. From January, the Building Safety Regulator will also become independent from the Health and Safety Executive, which is intended to strengthen its capacity and focus as it continues to manage high volumes of Gateway 1–3 applications.
Recent updates show the BSR is making progress on clearing delays in Gateway 2 approvals: the number of older, outstanding cases was almost cut in half over 12 weeks, and more than 500 applications were processed. The regulator has also restructured its process, shifting new-build higher-risk building cases into an “Innovation Unit” to increase throughput, although overall volumes remain high and remediation cases continue to experience delays.
The Budget did not provide additional direct support, funding or legislative measures to accelerate these processes. Instead, implementation challenges around Gateways 1–3 remain, and while BSR operational reforms are helping, approvals are still likely to be a limiting factor for project timelines. The regulator aims to clear its legacy Gateway 2 backlog by the end of January, but the Budget itself did not materially influence this trajectory.
Disputes & Risk Management
Evolving disputes and risk environment for construction and engineering firms:
Housing Market
House prices are rising only marginally and remain below inflation. First-time buyer activity is subdued, and valuation pressures at the upper end of the market (e.g., mansion tax discussions) create market uncertainty. Consultancy capacity remains constrained.
How can we help?
Conclusion
The Autumn Budget offers some constructive elements (infrastructure funding, planning capacity, skills support), but also substantial cost pressures and limited support for private housing demand or immediate sector-wide growth. For firms like ours, the most sustainable path forward lies in sensible risk management and selective tendering.
As 2025 draws to a close, the planning industry finds itself at a pivotal moment. The latest Brookbanks podcast brings together leading voices from across the sector to reflect on whether this year delivered the transformation promised, and what lies ahead as we move into 2026.
When it comes to large-scale development, policy is the easy part. The real challenge? Turning planning requirements into deliverable masterplans that survive detailed design and actually work on the ground. That was the focus of our recent webinar, where we shared practical insights from the Brightwell Lakes project near Ipswich, a 2,000-home scheme shaped by complex ground conditions, mineral extraction, and sensitive transport corridors.
In this episode of the Brookbanks podcast, Danny Lloyd-Jones and Jack Kenny from Brookbanks join Guy Kippen of Prime Plc to explore the evolving landscape of healthcare development in the UK. Together, they discuss innovative approaches to improving NHS infrastructure and creating better environments for staff and patients.
