Billions in Developer Contributions Remain Unspent Across UK Councils
More than £9bn in developer contributions specifically earmarked for essential community infrastructure including schools, transport networks, healthcare facilities and affordable housing is currently sitting unspent in council bank accounts throughout the United Kingdom, according to startling new research findings. A comprehensive freedom of information survey conducted by the Home Builders Federation has revealed this massive financial stagnation at the local government level.
Breakdown of Unallocated Funds
The detailed analysis estimates that approximately £6.6bn in Section 106 payments alongside £2.2bn raised through the community infrastructure levy remain completely unused. Perhaps most concerning is that nearly £3bn of this substantial total has been held inactive for more than five consecutive years, despite numerous agreements explicitly requiring these funds to be deployed within that specific timeframe.
To provide crucial context, annual government spending on affordable housing grants is projected to total between £2.5bn and £3bn for the remainder of the current parliamentary term. This means local councils are effectively holding the equivalent of several years' worth of central government funding within their accounts without deploying these resources for their intended purposes.
Concentration of Unused Resources
On average, each local authority holds approximately £19m in unspent Section 106 infrastructure contributions combined with £13.9m in unused community infrastructure levy funds. However, these substantial sums demonstrate significant concentration across different regions. Tower Hamlets alone maintains more than £260m in unallocated contributions, representing around nine times the national average when calculated on a per-household basis.
The Home Builders Federation reports that unspent balances have actually increased by £800m since mid-2024, despite overall developer contributions declining in parallel with weaker housing supply across the country. This counterintuitive trend highlights systemic issues in fund allocation and project implementation.
Specific Infrastructure Sectors Affected
Around £700m specifically allocated for affordable housing construction and £2bn earmarked for educational facilities remain completely unused, alongside £320m intended for establishing new healthcare facilities. In certain instances, £128m is being held by NHS integrated care boards after being transferred from local councils. In other cases, requests from health organizations for access to these designated funds have reportedly been refused or simply ignored by local authorities.
Planning Delays and Capacity Crisis
This revealing report emerges as the Labour government aims to deliver 1.5 million new homes during this parliamentary term, a target already facing significant pressure from rising construction costs, persistent planning delays and increasing investor caution. Recent analysis indicates that almost every local authority would miss statutory planning targets without relying on deadline extensions known as "performance agreements," demonstrating the substantial strain on planning departments following years of consistent funding reductions.
Spending on planning services has fallen nearly 17 per cent since 2010, creating severe capacity constraints. Meanwhile, new data shows applications for new residential developments have surged in parts of England following recent planning reforms, but actual housing completions remain notably subdued. The build-to-rent sector has also issued warnings about squeezed profit margins and slower delivery timelines, with John Lewis recently abandoning its housing venture amid challenging economic conditions.
Significant Opportunity Cost
Given this broader context, the enormous scale of unspent developer contributions represents what the Home Builders Federation characterizes as a "significant opportunity cost" for communities nationwide. Neil Jefferson, chief executive of the federation, stated emphatically: "This money should be funding schools, healthcare, affordable housing and other essential local infrastructure, yet billions sit completely idle, in some cases for over five consecutive years."
Jefferson continued: "The systematic underutilization of developer contributions represents a damning indictment on the ability of local councils to deliver tangible benefits to their communities." Meanwhile, the proportion of councils publishing mandatory infrastructure funding statements by the December 31 deadline has declined from 90 per cent in 2020 to just 75 per cent in 2025, indicating deteriorating compliance with reporting requirements.
Council Perspectives and Government Response
Local councils argue that funds are frequently pre-allocated to specific infrastructure projects and that delivery can be significantly slowed by persistent staffing shortages and procurement complexity. Government ministers have recently increased local government funding allocations and pledged additional resources specifically for planning departments.
However, with £9bn sitting unused—roughly 55 per cent more than the £5.8bn of newly announced local services funding—substantial pressure is mounting on councils to deploy existing resources before citing infrastructure constraints as legitimate grounds to resist new development proposals. For a government betting heavily on accelerated housebuilding to drive economic growth, unlocking this substantial capital could prove equally as crucial as sourcing new investment streams.
