How to use this list

Three practical filters to narrow the relevant programmes for any given project:

  1. By organisation type

    Public-sector organisations have devolved-nation schemes and most regional combined-authority programmes; PSDS closed to new applications in November 2024. Private-sector organisations primarily access Investment Zones (where designated), Innovate UK / UKRI competitions for novel projects, and the standard tax-allowance routes (50% FYA, AIA) which apply UK-wide regardless of region.

  2. By geography

    Cross-reference your operating address against the regional programmes. Scotland, Wales, and Northern Ireland have their own dedicated schemes that don't overlap with English regional programmes. Within England, Investment Zone designations and Combined Authority footprints determine specific programme eligibility.

  3. By project structure

    Solar-only applications struggle in cluster decarbonisation programmes. Most regional cluster funds (Solent, Humber, Black Country, Mersey-Dee) prioritise heat decarbonisation and process electrification, with solar accepted as a supporting measure. Solar-led applications work better in dedicated solar funds.


Cross-checking before application

Programme rules update annually or more frequently. Before any formal application, verify:

  • Current application windows (most regional funds run 2-3 windows per year)
  • Current programme rules (eligibility, qualifying spend categories, geographic boundaries)
  • Current grant intensity (varies by programme phase and budget allocation)
  • Match-funding requirements (some programmes require 30–50% private match)
  • Evaluation criteria (cost-per-tonne thresholds in particular)

When the standard tax-allowance route is the answer

For most private-sector commercial solar projects in the UK, the regional funds listed above are not directly accessible — and the standard tax-allowance route (50% FYA + special-rate pool, or AIA) delivers materially more value than what most regional funds would offer to private-sector applicants. Don't over-invest in regional fund hunting if your project sits squarely in the tax-allowance-route category.

Frequently asked questions

What regional solar funding programmes are available in the UK in 2026?
Over 30 regional programmes supplement national incentives in 2026, including the Welsh Government Low Carbon Transition Fund, Greater Manchester Clean Growth Fund, West Midlands Net Zero Capital, and several LEP-administered retrofit funds. Eligibility, grant percentages, and application windows vary significantly by region.
Can regional solar grants be combined with national tax allowances like the 50% FYA?
Yes, in most cases. The 50% First Year Allowance applies to the full capital cost before any grant is received, but the grant itself reduces the base cost for subsequent years' allowances. Most regional funds explicitly permit stacking with HMRC tax reliefs, though a few specify that the grant-funded portion cannot also be claimed for capital allowances. Check each fund's terms individually.
Which UK region offers the strongest solar funding package in 2026?
Business Energy Scotland's interest-free SME loan states it is not accepting new applications for solar PV projects (checked 26 Sept 2026), so Scottish businesses use the standard finance routes and the UK-wide capital allowances.
How do I find out if a regional solar fund is open for applications?
Fund windows open and close without much publicity. The most reliable approach is to check your Local Enterprise Partnership website, your combined authority's net-zero portal, and Business Energy Scotland or the Welsh Government business grants page directly. A commercial solar finance adviser can also track active windows — application quality matters as much as timing for competitive funds.
