From pipeline to delivery

WHAT CHANGED

The Budget did not deliver a single construction package. Instead, it combined fiscal devolution, targeted infrastructure commitments and new skills requirements. Mayors will retain a 20% share of locally retained business rates from April 2027, with local and regional government intended to retain 100% by the end of the decade. The first Business Rates Retention Zones include the Greater London Authority and several mayoral areas, while a £150 million uplift in capacity funding is intended to help Strategic Authorities use their expanded powers. 

On skills, the Government committed £100 million over two years to expand local apprenticeship services and set a target for apprentices to represent at least 3% of the workforce on large government infrastructure and construction projects. The Budget also confirmed selected transport and regeneration measures, including business-rates-backed funding mechanisms at Euston and Stratford.

WHAT THIS MEANS

The Budget shifts part of the development debate from national permission to local delivery. Giving mayors and councils a clearer financial stake in business-rate growth should strengthen the incentive to support commercial development and reinvest in enabling infrastructure. Business Rates Retention Zones could be particularly useful where transport capacity or upfront infrastructure costs are holding back otherwise viable schemes. 

That is a constructive change, but it is not a complete answer to the construction challenge. The practical effect will depend on the quality of local growth plans, the availability of investable projects and the capacity of public bodies to structure and deliver them. The additional funding for Strategic Authorities recognises this constraint, although delivery capability will take time to build and will vary across places. 

The skills measures are similarly directionally positive. Local apprenticeship brokerage and the 3% target on major public projects should create a stronger link between the construction pipeline and workforce development. Yet the scale of the challenge remains substantial: Skills England projects that employment across 30 priority construction occupations will need to rise by 493,000 by 2035. Apprenticeship access must therefore be matched by employer participation, training capacity and retention if it is to ease labour constraints rather than simply redistribute them. 

London offices illustrate the tension: 11.5 million sq ft of speculative space is under construction to 2032, yet our analysis still indicates a 9.0 million sq ft supply gap by 2030 against conservative assumptions of leasing demand. The Budget improves some of the machinery around delivery, but it does not remove the need for viable funding structures and resilient supply chains. 

Developers and investors should now focus on where the new local incentives align most clearly with infrastructure investment and deliverable schemes. The strongest opportunities are likely to emerge where mayors can combine retained revenues, planning powers and credible project pipelines, rather than where policy ambition exists without a route to finance and construction. 

BOTTOM LINE 

The Budget makes a useful move from centralised ambition towards locally enabled delivery. Business-rates retention can give places a stronger reason to support growth, while the apprenticeship measures begin to address the workforce needed to build it. But the decisive test remains viability. Without progress on finance, costs, contractor resilience and infrastructure capacity, a larger pipeline will not automatically become a larger volume of completed development.
