Solar panel grants in East Sussex

Warm Homes: Local Grant in East Sussex

The one scheme on this page that is a grant, and at this end of East Sussex it runs through Lewes District Council rather than any national form. From the government’s guidance page, last updated 2 July 2026 and read on 15 October 2026:

• Delivered by Lewes District Council for Lewes, Newhaven, Peacehaven and Seaford — England only, local authorities, no national application.
• For low-income households in privately owned homes — owner-occupied or privately rented.
• The home needs an Energy Performance Certificate rated D to G.
• The measures “could include” insulation, solar panels and an air source heat pump where suitable; the guidance does not promise solar for every eligible home.
• Funded with £500 million at the Autumn Budget, with delivery beginning in 2025.

At the end of East Sussex we cover that means Lewes District Council for Lewes, Newhaven, Peacehaven and Seaford, with East Sussex County Council behind it; the National Park Authority decides planning inside the Park but has no part in the grant. The eligibility test is income and the EPC band, and the measures are decided home by home — so the honest first step is the council’s own page, not an installer’s promise. If you qualify and solar is on the list for your house, we will survey it the same way we survey any other.

Lewes District Council, the Park and the EPC

The Warm Homes: Local Grant at this end of the county is delivered by Lewes District Council, and the test is the household and the Energy Performance Certificate, not the address. The older flint and brick stock in and around Lewes often sits in the D to G bands the scheme is aimed at; the post-war bungalows on the coast can go either way depending on what has been done to the loft and the walls. Find the certificate on the national EPC register first, because an A to C rating closes the door before income is even asked about. The National Park changes who decides the planning on a Lewes roof; it has no part in the grant.

East Sussex County Council declared a climate emergency in October 2019 and set a carbon-neutral target of 2050 at the latest for its own activities, which tells you the direction of travel without changing the eligibility test.

The roofs we find in East Sussex, the towns we reach and the planning position are on our solar panels in East Sussex page; this page is only the grant side of the same decision.

Zero-rate VAT

Domestic solar panels and battery storage attract zero-rate VAT rather than the standard rate — the same at Lewes inside the Park as on a Peacehaven bungalow. It is already in the price you are quoted; there is no form, nothing to claim back and nobody to apply to. Where it occasionally matters is a mixed job — solar work on the same invoice as unrelated electrical work can be treated differently — and if a quote has a VAT line you were not expecting, that is a fair question to ask. The whole of it, with the export scheme, is in zero VAT and the Smart Export Guarantee, explained plainly.

The Smart Export Guarantee in East Sussex

Not a grant, but the scheme most often mistaken for one. Larger suppliers must offer an export tariff; you choose one, and it does not have to be the supplier you buy from, and UK Power Networks is the operator for every address from Lewes to Seaford. The rate we point people to first is Octopus Energy’s Outgoing Octopus (Fixed) at 12p a unit — correct as of June 2026, cut from 15p to 12p on 1 March 2026, re-checked by November 2026. To be eligible the installation needs MCS certification, or an equivalent, and an export-capable meter; the certificate is part of what we do. Export rates sit well below what you pay to import, which is why using your own generation is where the value is and why battery storage is the next conversation. What a system is worth a year in East Sussex, worked through from the official yield data, is on solar panel cost in East Sussex.

Group buying in East Sussex

Solar Together Sussex — the group-buying scheme the Sussex councils have run with iChoosr — reported over 1,600 homes fitted through the scheme by its third phase in 2023. When we read the scheme’s site on 15 October 2026 (now Switch Together) it carried no East Sussex round of its own, so check whether a Sussex round is open before you count on it. Group buying is a reverse auction with one chosen installer, not a grant.

The Sussex group-buying rounds, and what they tell you

Solar Together Sussex put more than 1,600 systems on Sussex roofs by its third phase in 2023, which makes its offer the most-used benchmark in the county: one installer chosen by reverse auction, one price for a standard roof. On 15 October 2026 the scheme’s site, now Switch Together, carried no East Sussex round of its own, so the first question is whether a Sussex round is open at all. When one is, use its price as the yardstick — a quote far below it has left something out, one far above it should say what it added — and remember that the round prices the county, not your roof. A clifftop bungalow at Peacehaven and a listed house in Lewes are not the same job, and only a survey tells them apart.

Three things that are called grants in East Sussex and are not

“Free solar panels” on the coast — there is no such thing as free solar

The rent-a-roof model that fitted panels for nothing and kept the export income for two decades went with the Feed-in Tariff. An offer of free solar panels in Peacehaven or Seaford today deserves the small print read twice: who owns the array, what happens on sale, who is paid for the export. What is real is a reduced price through a scheme you qualify for, or a system you own outright.

“Government-backed” monthly plans

A finance plan is a finance plan however it is badged. Our homepage finance calculator shows the shape of a monthly figure for an honest system with no APR published, because the real rate comes with the written quote — and no repayment plan is a grant.

“Lewes qualifies for free panels”

The Warm Homes: Local Grant is tested on the household and the EPC band; the National Park, the town and the postcode have nothing to do with it. Anyone who says a whole town qualifies has not read the guidance.

Questions we get asked in East Sussex

Is there a solar panel grant in East Sussex?

Not a general one. No national grant pays towards solar panels for most households and the Feed-in Tariff closed in 2019. What exists: the Warm Homes: Local Grant for eligible low-income households in homes rated EPC D to G, delivered through Lewes District Council; zero-rate VAT on domestic solar and batteries, already in a proper quote; the Smart Export Guarantee, which pays for what you export; and the Sussex group-buying rounds, which are a reverse auction rather than a grant.

Does living in the National Park change what I can claim?

No. The Park changes the planning position — the National Park Authority decides applications and a flat-roof array on designated land needs prior approval — not the money. The Warm Homes: Local Grant is tested on income and the EPC band; VAT and the Smart Export Guarantee apply the same way inside the Park as outside it.
