The UK solar panel grant landscape in 2026 is narrower than it was a decade ago but still meaningful for the households that qualify. The original Feed-in Tariff is long gone, replaced by the Smart Export Guarantee. Targeted support exists for lower-income households through ECO4, the Home Upgrade Grant, and the new Warm Homes Local Grant. Here’s what’s available, who qualifies, and what’s not.
The honest baseline: no universal solar grant exists
Let’s address this first because it confuses a lot of people. There is no general grant for solar panels in the UK in 2026 that anyone can apply for regardless of income or property type. The Feed-in Tariff scheme that ran from 2010-2019 paid generous per-kWh rates for solar generation; it closed to new applicants in March 2019 and is not coming back.
What does exist is targeted financial support for specific situations — low-income households, off-gas-grid properties, social housing, and tenancy/landlord scenarios.
Smart Export Guarantee (SEG) — not a grant but worth knowing
The SEG is the legal replacement for the Feed-in Tariff. It pays you for any surplus solar electricity exported to the grid. Every UK electricity supplier with over 150,000 customers must offer an SEG tariff.
Anyone with an MCS-certified solar installation and a smart meter qualifies. There’s no income test, property type restriction, or means assessment. You just choose an SEG supplier and register.
Rates in 2026:
- Octopus Outgoing Fixed: ~15p/kWh
- Tesla Energy Plan: up to 24p/kWh (Powerwall customers only)
- British Gas Export & Earn: 6-15p/kWh
- EDF Export+: 7-10p/kWh
- Eon Next Export: 3-7p/kWh
For a typical 4kW system in the North East exporting ~1,500 kWh/year, that’s £45-£360 annual income depending on supplier choice. We covered this in detail in our Smart Export Guarantee explained 2026 post.
ECO4 (Energy Company Obligation)
ECO4 is the current iteration of the obligation on large energy suppliers to fund energy efficiency measures for low-income households. Solar PV can be funded under ECO4 in specific cases — typically as part of a wider package alongside insulation, heat pump or other measures.
Who qualifies: Households on certain qualifying benefits (Universal Credit, Pension Credit, Income Support, Child Tax Credit, JSA, ESA, and others), or households in the lowest income deciles for specific local authority areas (LA Flex eligibility).
What you get: Up to 100% funding of installation cost in some cases, partial funding in others. ECO4 prioritises lowest-EPC properties (E, F, G) and households in fuel poverty.
Process: Apply through an approved ECO installer. ECO4 doesn’t pay homeowners directly — funding is administered through installers who claim back from the obligated energy supplier.
Solar-specific note: ECO4 prefers heating measures (heat pumps, insulation) over solar PV. Solar is funded under ECO4 mostly where it’s combined with a heat pump and there’s documented benefit to the household’s energy security. Standalone solar applications under ECO4 are rarer.
Home Upgrade Grant (HUG)
HUG specifically targets off-gas-grid households in the lowest EPC bands. It’s administered through local authorities and provides up to £15,000 of energy efficiency measures per household, depending on local funding allocation.
Who qualifies: Off-gas-grid households (oil, LPG, electric heating, solid fuel) with EPC ratings of D, E, F or G, and household income under £36,000 per year. Specific eligibility varies by local authority — Northumberland County Council, Durham County Council and Newcastle City Council all administer HUG funding differently.
What you get: Solar PV can be included as part of a HUG package alongside insulation, heat pump or other improvements. Standalone solar funding under HUG is unusual.
Process: Apply through your local authority. Application windows vary; some councils have rolling applications, others run defined application periods.
Warm Homes Local Grant
Replaced the older Warm Home Discount and similar schemes in 2025-2026. Administered through local authorities with funding from central government. Targets fuel-poor households with energy efficiency improvements including solar PV in some cases.
Eligibility varies significantly by local authority. Northumberland, Durham, Newcastle, Gateshead, South Tyneside, Sunderland, Hartlepool, Stockton-on-Tees and Middlesbrough all operate variants with slightly different rules. We check current eligibility for AMP customers as part of every survey.
Typical funding: Up to £10,000 per household, depending on local authority allocation and the measures funded.
Public Sector Decarbonisation Scheme (PSDS) — commercial only
PSDS is the main support route for non-domestic buildings — schools, NHS estates, councils, universities, social housing. Phase 4 (currently active) funds heat pump installations and can include solar PV as part of an integrated decarbonisation project.
Who qualifies: Academy trusts, LA-maintained schools, NHS trusts, FE colleges, universities, local authorities, housing associations, emergency services. Solar-only applications are uncommon — PSDS prioritises heating decarbonisation.
Funding levels: Up to 100% of capital cost for qualifying projects.
For commercial businesses (not public sector), solar funding comes through capital allowances (Annual Investment Allowance) and asset finance rather than grants. Covered in detail on our commercial solar service page.
What’s not available
Worth being explicit about what does not exist as of May 2026:
- No universal homeowner grant for solar PV. Despite occasional rumours, there’s no replacement for the original Feed-in Tariff for general homeowners.
- No solar VAT relief that helps individuals. The 0% VAT on energy-saving materials (introduced April 2022, extended to 2027) is a supplier-side measure — your installer charges 0% VAT to you. It’s already reflected in our quoted prices.
- No green mortgage that pays for solar. Some lenders offer rate discounts for properties with renewable upgrades; that’s a financing mechanism, not a grant.
- No specific solar subsidy for new builds. Future Homes Standard from 2025 requires new builds to be designed for low-carbon heating, but solar PV isn’t mandated — developer responsibility, no homeowner-side funding.
Solar pricing without grants — still attractive
Honest assessment: solar PV in 2026 has competitive economics even without grants. A 4kW install from £4,999, paying back in 7-9 years through bill savings + SEG income, generating revenue for 25+ years afterwards — the case stands up without any grant subsidy.
For most homeowners, the question isn’t “what grant do I qualify for?” but “does the unsubsidised case work for my home?” For most North East homes with reasonable south or east-west roof aspects, the answer is yes.
For lower-income households who do qualify for ECO4, HUG or Warm Homes Local Grant, that’s a strong supplementary route — but the underlying case for solar in 2026 doesn’t depend on grant funding the way it did under the original Feed-in Tariff.
What about battery grants?
Same picture: no general homeowner grant for batteries in 2026. ECO4 funding can include battery storage as part of a wider package in some cases. Beyond that, the case rests on tariff arbitrage economics, which work well on Octopus Go or similar smart tariffs.
We covered battery economics in our Best home battery UK 2026 comparison — short version: a 10kWh battery typically delivers £400-800/year savings on its own, more when paired with solar, on no grant basis.
What about heat pump grants?
Different scheme entirely — £7,500 Boiler Upgrade Scheme grant for heat pumps. Available to homeowners regardless of income. Detailed in our Boiler Upgrade Scheme 2026 complete guide.
Heat pump + solar together is the strongest grant case for most homeowners — the £7,500 BUS on the heat pump effectively cross-subsidises the solar capital expenditure if you’re doing both at once.
Getting clarity on your eligibility
If you think you might qualify for ECO4, HUG or Warm Homes funding, we check eligibility for free as part of every AMP survey. We work with the major Northumberland and County Durham local authorities and have current contacts at the ECO4 administering bodies. Where you don’t qualify for grant funding, we’ll tell you straight — there’s no point chasing applications that won’t land.
