Green Energy Grants UK 2026: What Financial Help Is Available?

Green Energy Grant Schemes in the UK — 2026 Comparison

Nine schemes are relevant to UK homeowners in 2026 — some are live grants, one is a 0% VAT rule, and several are nation-specific (Scotland/Wales). Amounts and eligibility below are correct as of publication; always confirm current figures at gov.uk before applying.

Which Grant Can I Actually Get? Quick Eligibility Snapshot

Most guides describe each scheme in isolation and leave you to work out which applies to you. Here's a shortcut based on your situation:

ECO4 (Energy Company Obligation)

ECO4 funds energy efficiency improvements — including insulation and, in some cases, solar panels or heat pumps — for households on qualifying benefits (Universal Credit, Pension Credit, income-based JSA/ESA, and others) or with a low EPC rating (D, E, F or G). It's delivered through energy suppliers, not applied for directly at gov.uk — your installer or a broker registered with the scheme checks eligibility and submits the application on your behalf. ECO4 runs to March 2026 with a successor scheme expected to follow a similar model.

Boiler Upgrade Scheme (BUS)

BUS provides a £7,500 grant toward replacing a gas, oil, or electric boiler with an air source or ground source heat pump (biomass boilers also qualify at a lower rate). You must own the property (or have landlord consent), the existing fossil-fuel heating system must be removed, and your EPC must have no outstanding recommendations for loft or cavity wall insulation. There's no income means-test. Applications are made by your MCS-certified installer, not by you directly.

Warm Homes: Local Grant

Replacing the old Home Upgrade Grant in England, this scheme can cover up to £30,000 per household for insulation, heat pumps, and solar panels. Eligibility runs through three routes: living in a qualifying low-income postcode, receiving certain benefits, or falling under a local income threshold set by your council. Your EPC typically needs to be rated D to G. Rollout is managed council-by-council, so availability and exact criteria vary by local authority — check with your council directly.

Great British Insulation Scheme

Targets homes with low council tax bands (A–D in England, A–E in Scotland/Wales) and a low EPC rating, or households on qualifying benefits regardless of council tax band. Covers loft and cavity wall insulation, which improves the return on any solar or heat pump investment by reducing the heat/energy your home loses.

EV Chargepoint Grant (OZEV)

Provides up to £350 toward a home EV charge point, but eligibility narrowed significantly in 2022 — it's now available only to renters and people in flats with dedicated off-street parking. Homeowners in houses are no longer eligible for this specific grant (a common point of confusion, since older articles still describe the pre-2022 wider scheme). Apply through an OZEV-authorised charger installer, not gov.uk directly.

Smart Export Guarantee (SEG)

Not a grant but an ongoing income: energy suppliers with 150,000+ customers must offer a tariff paying you for solar electricity you export to the grid, and rates vary significantly between suppliers — from a few pence per kWh up to 15p+ on the best current tariffs. Any home with an MCS-certified solar installation (up to 5MW) is eligible. Shopping around for the best SEG tariff, rather than staying on your installer's default supplier, can meaningfully change your solar payback period.

0% VAT on Energy-Saving Materials

Solar panels, heat pumps, insulation, and battery storage installed in residential properties in England, Scotland, and Wales qualify for 0% VAT (instead of the standard 20%) when installed by a VAT-registered installer. This isn't a grant you apply for — it's applied automatically by your installer at quote stage — but it's worth confirming your quote already reflects it, since some installers still quote at 20% by mistake. The relief is legislated to run until 31 March 2027.

Scotland & Wales-Specific Schemes

Home Energy Scotland Grant and Loan: Scottish homeowners can access up to £7,500 as a grant plus up to £7,500 as an interest-free loan (higher amounts available in rural and island postcodes) for heat pumps, solar panels, and insulation. Applied for through Home Energy Scotland, not gov.uk.

Warmer Homes Scotland: A separate, needs-based Scottish scheme that can cover the full cost of measures including heating systems and insulation for households meeting age, health, or benefits criteria plus a council tax band/floor area limit.

Nest Wales: Offers free energy efficiency improvements — insulation, heating upgrades — for Welsh households on qualifying benefits or with a relevant health condition, regardless of tenure.

Expired Schemes — Don't Apply to These by Mistake

Several older schemes are frequently confused with current ones in search results and forums: the Green Homes Grant (closed 2021), the domestic Renewable Heat Incentive (RHI) (closed to new applicants 2022, replaced by BUS), the Feed-in Tariff (closed to new applicants 2019, replaced by SEG), and the pre-2022 wider Free Solar Panel Scheme eligibility. If a third-party site or cold caller references any of these by name as currently available, treat it as a red flag.

How to Apply for Green Energy Grants

There's no single application portal for every scheme. The gov.uk energy grants calculator is the correct starting point for England-wide schemes (ECO4, BUS, Warm Homes: Local Grant, insulation). For BUS specifically, your MCS-certified installer submits the grant application on your behalf as part of the quote process — you don't apply separately. For the EV Chargepoint Grant, your OZEV-authorised installer handles the application. Scottish and Welsh residents should go directly to Home Energy Scotland or Nest Wales rather than gov.uk, since those schemes are devolved and not listed on the England-wide calculator.

Be wary of third-party websites or unsolicited calls claiming to offer "free grants" that require an upfront fee, or that pressure you to sign on the same call — always start at gov.uk or the devolved scheme's own site to verify a scheme is genuine before sharing any details. Once you know your eligibility, use the MCS installer finder to find a certified installer who can confirm which grants apply to your specific property and handle the application for you.
