Solar grants for UK councils and local authorities — Salix, Local Growth Fund and post-PSDS funding.
PSDS Phase 4 closed but UK councils have multiple active 2026 routes: Salix BAU loans, LCSF, Local Growth Fund (Mayoral Authority areas), Welsh and Scottish equivalents. Council-wide programmatic rollouts continue to deliver across civic, leisure, library and depot estates.
The 2026 council solar funding stack
- Salix Finance interest-free loans (BAU) — separate from closed PSDS, repaid from energy savings, effectively zero net cost. Active for all UK public sector.
- Low Carbon Skills Fund — Salix-administered HDP funding, typical awards £25-80k per estate. Recommended starting point.
- Local Growth Fund — £1.5bn over 3 years, 11 Mayoral Strategic Authority areas. Capital grants for major projects.
- Welsh Government council decarbonisation programmes (Welsh councils only)
- Salix Scotland equivalents (Scottish councils)
- NI DfE programmes (Northern Ireland councils)
- Power Purchase Agreements — for larger council portfolios with strong covenant strength
Council estate building types — solar fit
Leisure centres (strongest payback)
Pool heating, refrigeration for cafe/bar, gym equipment, lighting all run continuously. Self-consumption rates 85-95%. Typical 200-500kWp projects.
Civic offices
Mon-Fri 8-6 demand profile. Self-consumption 55-72%. Typical 100-300kWp projects. BREEAM credit value often dominant in modern civic offices.
Council depots and waste sites
Mixed demand profiles. Larger depots (refuse, parks, highways) often have continuous low-load plus daytime peak from vehicle maintenance. Typical 200-500kWp.
Libraries and community centres
Variable demand patterns. Self-consumption 55-72%. Typical 30-100kWp. Often combined with community-fund elements (GBE Community Fund eligible for community-benefit aspects).
Council-maintained schools
Where the council is the maintaining authority. See schools-specific guide.
Social housing common areas (not residential)
Common-area lighting, lift motors, communal heating circulation. Modest project sizes. Council solar typically focuses on the housing depot, communal halls and similar.
Worked example — typical UK council 2026
A district council with 18 buildings (civic, leisure, libraries, depots) totalling 95,000 m²:
- LCSF application: £45k awarded — covers HDP across all 18 sites
- Salix BAU loan: £1.8m across 12 strongest-payback sites (combined PV + LED + BMS upgrades)
- Local Growth Fund (council in eligible Mayoral Authority area): £350k contribution
- Council capex contribution: £0 capex; £40k internal project management
- Annual savings (across 18 sites): £215k
- Loan repayment from savings: ~5 years
- Net annual savings to council after loan: £215k/year for 18+ years

Funding by asset class
The allowance depends on the asset, and most pages on this topic get it the wrong way round. Solar PV is special-rate expenditure (HMRC Capital Allowances Manual CA22335), so the 100% year-one route is the Annual Investment Allowance — Full Expensing is a main-rate measure and does not reach it. Battery storage, EV charging and heat pumps are main-rate plant, so Full Expensing genuinely does apply to those.
- what a commercial heat pump actually costs in 2026
Main-rate plant, so Full Expensing does apply here.
- what commercial battery storage costs per kWh
Main-rate plant. Stacks with solar for self-consumption.
- the real cost of a commercial solar install
Capex bands per kWp before any relief.
- industrial rooftop solar economics
Large roofs, high daytime load — the strongest case.
- claiming the Annual Investment Allowance on solar
Solar is special-rate, so AIA is the 100% year-one route.
Find out which 2026 schemes your site actually qualifies for
- 1. A short written funding note naming every scheme your site qualifies for in 2026 — and the ones it does not.
- 2. Indicative system size and a capex band for your roof.
- 3. Year-one tax treatment per asset in £ — solar is special-rate expenditure, so the route is the Annual Investment Allowance; battery storage and heat pumps are main-rate plant, where Full Expensing does apply. Most pages get this the wrong way round.
- 4. Projected SEG export revenue at current rates.
- 5. Any red-flag eligibility or DNO issues we can see up front.
Covers solar PV, battery storage, EV charging and commercial heat pumps — separately or as one bundled project. If your project is a heat pump or a battery rather than a roof, say so in the message box and the note is written against that asset instead.
