Solar panels in East Sussex

What we find on East Sussex roofs

Two jobs in one county: listed flint and tile under the Downs at Lewes, and salt-air bungalows on the clifftop at Peacehaven — the survey decides which rulebook applies before it decides the panels.

Distance, geography, housing stock and the planning position all change how a system gets designed. These are the ones that decide it in East Sussex.

Lewes, the Park and the coast

The East Sussex we cover is two different jobs. Lewes and the villages around it are inside the National Park, on flint, brick and tile under the Downs, where the Park Authority decides planning and the usual question is a listed building or a conservation area rather than the roof itself. Peacehaven and Newhaven are the coast: post-war bungalows and semis on the clifftop, in salt air, where the roof is simple and the fixings are not. Thirty road miles is where our regular area stops, and on this edge the line falls at Newhaven. Seaford, Uckfield, Hailsham and Eastbourne are all beyond it; we will tell you so rather than quietly add the travel to the price.

Our Brighton & Hove page covers the city between here and the rest of the patch, on the same network operator and the same coastal rules.

What Solar Together tells you about a quote

The Sussex councils’ group-buying scheme has put panels on more than sixteen hundred homes across the county, and that is a useful thing to know even if you never register for it: it means there is a published benchmark for what a vetted installer charges for a system of a given size in this county. We are happy to be measured against it. What a scheme price does not include is the part a survey decides — a scaffold on a clifftop in Peacehaven, a listed roof in Lewes, a battery wall that has to be found rather than assumed — and those are the lines we itemise rather than average.

Home batteries on the eastern edge

On the coast the wall that is free is sometimes the one facing the sea, and a battery does not want to be there; inland the question is usually an outbuilding in a conservation area. Either way the installation is to PAS 63100, as the wiring regulations have required since April 2026, and the inverter is notified to UK Power Networks before it is energised. The Fox ESS pairing, the Sigenergy stack and the other lines we fit are set out plainly, and whether a battery is worth it at all on your usage is a question we answer before the brand one.

What the sum looks like at this end of the county is worked through on solar panel cost in East Sussex — the PVGIS yield for Lewes, the best of the three county points we measured, against the published starting range and the Energy Saving Trust average — and the honest list of what is and is not a grant is on solar panel grants in East Sussex; the Park and the coast, planning-wise, are in solar panels and planning permission in East Sussex. Adding a battery to panels Solar Together put on the roof is the job this edge asks for most: battery storage in East Sussex and the retrofit post are written for it.

Solar panel installers on the East Sussex edge: how a job runs

Two jobs in one county. At Lewes the South Downs National Park Authority is the planning authority, almost all the historic town is a conservation area with an Article 4 direction, and the survey settles the rulebook before it settles the panels. On the clifftop at Peacehaven and Newhaven it is salt-air bungalows with simple roofs, where the thirty-to-forty-five-minute survey is about the exposure — marine-grade fixings, clamps and containment as standard — and the garage wall for the battery.

The scaffold is in the quote; installation is typically one to two days; the certificate is signed by our own NICEIC-registered electricians and the registrations arrive in your name. The whole of this end of the county is UK Power Networks — BN7, BN9, BN25 and TN22 — so the G98 notification or G99 application goes to the same operator as Brighton. Solar panels in Lewes has a page of its own; Peacehaven is covered from here and Newhaven sits just over the thirty-mile line.

Battery storage, EV charging and the electrics on the East Sussex edge

Adding a battery to panels Solar Together put on the roof is the job this edge asks for most — battery storage in East Sussex and the retrofit post are written for it.

For a car, EV charger installation in East Sussex. East Sussex County Council secured £4.441m under tranche 1 of the government’s Local Electric Vehicle Infrastructure fund in February 2024, one of the first five authorities to receive it, to help residents without off-street parking switch; it states that it is not permissible to charge a vehicle by running a cable across the road or pavement even with a cable protector, and that the government grant for residents without private parking needs the local highway authority’s approval. A house with its own off-street space can have a home charger; a flat owner or renter with private off-street parking can claim 75% of it up to £500.

What solar costs on the East Sussex edge, and what it pays

Most domestic installations typically start from around £4,000 to £6,000 depending on the size of the home and the amount of energy it uses; domestic solar and battery storage currently attract zero-rate VAT; the published average saving is £300–£600 per year, sometimes more with a battery or by working from home during the day. Solar Together Sussex — over 1,600 homes by its third phase in 2023 — remains the fair yardstick to hold any quote against, and what solar costs in East Sussex carries the worked example at Lewes’s own yield.

That yield — about 1,177 kWh per kWp a year for a south-facing 4.5 kWp array, PVGIS 5.2 — is the best of the three regions we publish. The surplus is exported at the Smart Export Guarantee rate, 12p per kWh in our reference as at June 2026, against about 26p to buy a unit back.

The East Sussex edge in numbers

Lewes 23 and Peacehaven 26 road miles from Washington; Newhaven at 31 just over the line. UK Power Networks, group J, for BN7, BN9, BN25 and TN22. Lewes inside the South Downs National Park. Lewes District Council: climate emergency 2019, net zero by 2030, Newhaven as the whole-town test case; East Sussex County Council: climate emergency October 2019. ONS Census 2021: Lewes district around 99,900 residents, 71.1% owner-occupied, 16.9% private renting. £4.441m LEVI funding, February 2024. PVGIS about 1,177 kWh per kWp at Lewes.

Questions we get asked in East Sussex

Do you cover Eastbourne, Seaford or Uckfield?

Not as part of our regular working area. Eastbourne is about 39 road miles from Washington, Uckfield 32 and Seaford 33 — all beyond our thirty-mile line. Newhaven, at 31, is on it. We will still quote for a job just over the line, but we say so up front rather than hide the travel in the price.

Who notifies the electricity network for a Lewes or Peacehaven install?

We do. This end of East Sussex is on UK Power Networks, so the G98 notification — or the G99 application for an inverter over 16 amps per phase — goes to UKPN, the same operator as Brighton. Your MPAN, printed on your bill, confirms it, and you receive the acknowledgement.

How much do solar panels cost in East Sussex?

Most domestic installations typically start from around £4,000 to £6,000 depending on the size of your home and the amount of energy you use, with zero-rate VAT. Solar Together Sussex’s group-buying prices are a fair yardstick; the East Sussex cost page carries the worked example at Lewes’s yield, and the survey gives you a written figure.

Is Seaford or Eastbourne covered for solar panels?

Both sit beyond our thirty-mile line from Washington, as does Uckfield; Lewes and Peacehaven are inside it and Newhaven just over. If the line moves, this page will say so.
