£2.2bn unspent CIL: what it could mean for UK local road asset management
Reviewed by Tom Sullivan

First reported on New Civil Engineer
30 Second Briefing
More than £2.2bn in unspent Community Infrastructure Levy (CIL) contributions held by planning authorities in England and Wales could be redirected to tackle the growing local road maintenance backlog, the All-Party Parliamentary Group for Better Roads says. MPs want the government to simplify rules and improve transparency so councils can more readily use CIL funds for carriageway resurfacing, pothole repairs and structural renewals. For highway engineers, this signals potential medium-term funding for asset management plans and heavier interventions beyond reactive patching.
Technical Brief
- MPs argue CIL could fund full-depth reconstruction, surface course renewal and drainage upgrades, not just patching.
Our Take
For local authorities in England and Wales, unlocking even a portion of these contributions could provide match funding or risk buffers that make it easier to progress design-and-build contracts for road schemes that are otherwise stalled by revenue budget constraints.
Because New Civil Engineer also covers asset management and ‘data handover gap’ issues in UK infrastructure, this funding discussion is likely to intersect with pressures on councils to adopt more formalised asset management plans for roads, which in turn can help justify reallocating CIL money towards backlog reduction rather than ad hoc repairs.
