Quick answer

East Sussex is in the UKPN distribution area and rich in conservation areas and Article 4 streets (notably Brighton's Regency squares and Lewes). We specialise in discreet, consent-friendly systems and handle the UKPN G98/G99 connection.

East Sussex sits within UK Power Networks (UKPN) territory and carries a high density of conservation areas — from Brighton & Hove's Regency terraces to the Article 4 streets of Lewes. That makes sympathetic, low-profile design essential, and it is exactly where our experience pays off.

We cover the East Sussex coast as the far eastern edge of our service area, prioritising heritage-aware installations that win consent and still deliver strong generation.

What a 4kW system generates in East Sussex

Estimated annual output by roof direction, using East Sussex's irradiance. South-facing performs best; east/west roofs still generate strongly.

East-facing

West-facing

~3,300–3,700 kWh per year (roughly 15–20% below south)

Grants & export income

Be realistic about grants: most East Sussex owner-occupiers won't qualify for one. The fully funded schemes — ECO4 and the Warm Homes / Great British Insulation Scheme — are means-tested and generally reserved for low-income households or those on qualifying benefits, and county-wide group-buying rounds like Solar Together only run periodically and simply pool buying power rather than hand out cash. For the vast majority of homeowners the real ongoing earner is the Smart Export Guarantee (SEG): with an MCS-certified install and a smart export meter, you're paid for every unit you send back to the grid, and as of 2026 leading tariffs pay around 15p–27p per kWh depending on supplier and whether the rate is fixed or flexible. Suppliers set and change their own SEG rates, and you can hold your export tariff with a different supplier than your import one — we'll make sure your system qualifies.

FAQ

Solar panels in East Sussex: FAQs

How much do solar panels cost in East Sussex?
A typical home system across East Sussex costs from around £5,500–£11,000 depending on size and battery storage, with 0% VAT on residential solar. ~1,100 kWh/kWp per year — a 4kW system generates around 4,100–4,400 kWh. Every quote is tailored to your roof after a free survey.
Which electricity network (DNO) covers East Sussex?
UKPN (UK Power Networks). We handle the full G98 (smaller systems) or G99 (batteries and larger arrays) connection application on your behalf.
Do you need planning permission for solar panels in East Sussex?
Most installs are permitted development; conservation areas and listed buildings need sensitive design. The main planning authorities here include Brighton & Hove City Council, Eastbourne Borough Council, Lewes District Council, Hastings Borough Council. We advise per property and design discreet systems where required.
Which towns in East Sussex do you cover?
We install across East Sussex, including Brighton & Hove, Eastbourne, Lewes, Hastings. If your town isn't listed, just ask — we very likely cover it.
Which DNO covers East Sussex, and do I need a G99 application?
East Sussex sits in the UK Power Networks (UKPN) distribution area — not SSEN, which covers our Hampshire heartland. A solar-only system up to 3.68kW per phase falls under G98, so we simply notify UKPN after commissioning ('connect and notify'). Anything larger, and crucially anything with a battery or export, needs a G99 application submitted to and approved by UKPN before we install. We file whichever applies for your postcode, so there's nothing for you to arrange.
Can I put solar panels on my home in a Brighton or Lewes conservation area?
Often yes, but it needs care. In England roof solar is usually Permitted Development if the panels don't protrude more than 200mm or sit above the highest part of the roof. However, panels on a wall or roof slope fronting a highway in a conservation area — which covers many of Brighton & Hove's Regency terraces and Lewes's Article 4 streets — can need a full planning application, and any listed building needs Listed Building Consent. We design discreet, all-black rear-slope systems specifically to win consent in these heritage areas.
Is East Sussex sunny enough for solar to be worthwhile?
Yes — East Sussex gets around 1,100 kWh/kWp per year, among the highest irradiance in the UK thanks to its south-coast position. A south-facing 4kW array here typically generates about 4,100–4,400 kWh a year. East or west-facing roofs produce roughly 15–20% less than south, so around 3,300–3,700 kWh, which is still plenty to make solar and a battery pay their way. We model your actual roof orientation and pitch into every quote rather than quoting a generic figure.
