At a Glance — The Four Main Schemes in Wales 2026
The Welsh Government’s own scheme. Free solar panels, heat pumps and insulation for eligible households. Been running since 2011.
UK-wide scheme funded by energy suppliers. Wales gets broader eligibility — council tax bands A–E qualify. Closes 31 Dec 2026.
£5 million renewed for 2026–27 by the Welsh Government. Interest-free loans managed by the Development Bank of Wales.
No VAT on solar panel supply and installation in Wales. Applied automatically — no application, no forms, nothing.

Check out Solar panels grants uk If you live in Wales and you’re on a lower income, Nest is the first call you should make. The Welsh Government’s own scheme has been running since 2011 and has helped more than 66,000 households with free home energy improvements — solar panels very much included. Between October 2024 and March 2025 alone, 348 homes across Wales had solar panels installed through Nest. What’s good about Nest is that it’s not just a panel-drop. You get a tailored package based on what your home actually needs — solar alongside insulation, a heat pump, or even a boiler fix if that’s more urgent. It’s a whole-home approach, not a gimmick.🏡 Warm Homes Nest — The Welsh Government’s Flagship Scheme
Who qualifies?
Check out Are solar panels worth it in cornwall ECO4 is a UK-wide scheme that obliges the large energy suppliers — British Gas, EDF, E.ON, Scottish Power, and others — to fund free energy improvements for eligible households. It’s fully live and runs until 31 December 2026, so don’t hang about. In Wales you get a broader slice of eligibility than in England. Council tax bands A–E qualify here, compared to A–D south of the border, which opens it up to a much larger chunk of Welsh homes — particularly in valleys and rural communities where fuel poverty is higher. Watch out for outdated information. The Great British Insulation Scheme (GBIS) closed on 31 March 2026. A lot of older articles still mention it as live — it isn’t. ECO4 is the active free scheme.⚡ ECO4 — Free Solar via Energy Suppliers

In January 2026, Housing Secretary Jayne Bryant announced the scheme would receive more than £5 million in fresh funding for 2026–27, after it became oversubscribed in its first year. Since the programme launched in October 2024, the Welsh Government has invested nearly £12 million into it. Managed by the Development Bank of Wales, it offers interest-free loans you repay over up to 10 years — with a six-month holiday to start, so you’re not paying anything back while your panels are bedding in. One important requirement: you must have had a free advice call with Nest before applying. That’s non-negotiable under the scheme rules.🏦 Green Homes Wales — An Interest-Free Loan If You Don’t Qualify for Free
