Solar Panels Seaford: Installers for BN25
Solar, battery storage and EV charging in Seaford — designed and installed by a local, MCS-certified team based in Portsmouth.
Quick answer
Seaford (BN25) is on UK Power Networks' grid, and we file the G98 or G99 application for you. PVGIS puts a 4kW south-facing, unshaded array here at about 4,668 kWh a year — one of the strongest figures on our patch — and the town-centre conservation area carries no Article 4 direction.
Seaford is a Victorian seaside town on the East Sussex coast, east of Newhaven and west of Eastbourne, that revived in the 19th century with the arrival of the railway and is now the terminus of the Seaford Branch Line. It had 22,862 residents at the 2011 census. Seaford Head rises to the east towards the Seven Sisters, and the Martello tower at the end of the esplanade was built between 1806 and 1808.
For solar the headline is sunshine: PVGIS models one of the highest yields of any town we cover here. Seaford is about 52 miles from our Portsmouth base as the crow flies, so we plan East Sussex surveys and installs as dedicated visits rather than squeezing them into a local round.
Solar in Seaford: the local detail
Grid connection (DNO)
Seaford is in the UK Power Networks (UKPN) area, like the rest of East Sussex: our postcode checks put BN25 on the South Eastern network. G98 covers smaller systems; G99 (applied for in advance) covers batteries and larger arrays — SCSS files the application.
Local planning authority
Lewes District Council
Heritage & conservation
The national planning register records one conservation area in the town — Seaford (Town Centre), designated on 31 October 1968 — with no Article 4 direction over it, so panels on the roof slope of a house there normally keep permitted development. Walls, balconies and roof enclosures fronting a highway are excluded, flat-roof arrays need prior approval, and listed buildings need consent checked first.
Local housing stock
A Victorian and Edwardian seaside core with later suburban growth inland. HM Land Registry's July 2026 averages for Lewes district were £368,408 overall, £592,980 for detached houses, £398,378 for semi-detached, £324,315 for terraced homes and £197,656 for flats.
Typical roofs
PVGIS 5.3 gives a 4kW unshaded array about 4,668 kWh a year facing south, 3,571 facing east and 3,688 facing west — west-facing roofs edge out east-facing ones here. Seafront properties get corrosion-resistant fixings, and we check every roof for shading at the survey.
Sunlight & generation
PVGIS models about 4,668 kWh a year for a 4kW unshaded, south-facing array at a 35° pitch

Solar Panels Seaford: BN25 Yields, the Town-Centre Conservation Area and the UKPN Connection
Seaford gets more sun than most of the places we quote for. PVGIS 5.3 puts a 4kW unshaded, south-facing array here at about 4,668 kWh a year — ahead of Southampton (4,255) and Portsmouth (4,523) — with roughly 586 kWh arriving in June and 151 kWh in December. East-facing it models at about 3,571 kWh and west-facing at 3,688 kWh, so west-facing roofs slightly out-perform east-facing ones on this stretch of coast. About 3,236 kWh of the year lands between April and September.
The planning position is straightforward for most of the town. The national planning register records one conservation area here — Seaford (Town Centre), designated on 31 October 1968 — and no Article 4 direction over it. That matters because an Article 4 direction is the thing that can remove roof-slope permitted development rights; without one, panels on the roof slope of a house in the conservation area keep permitted development under the rules as amended on 27 August 2026. Walls, balconies and roof enclosures fronting a highway are the exception, a flat-roof array needs prior approval, and a listed building needs consent checked before any design.
Seaford is on UK Power Networks' South Eastern network, like the rest of East Sussex, which also sets your export region. On 25 September 2026 Octopus Flux paid 29.79p per kWh here for exports between 4pm and 7pm, 10.24p through the day and 5.05p between 2am and 5am; Outgoing Octopus pays a flat 12p. A battery or a larger system needs G99 approval from UKPN before installation, and we submit it.
The town itself is a Victorian seaside resort that, as its own history puts it, revived in the 19th century with the arrival of the railway; it sits east of Newhaven and west of Eastbourne under Seaford Head, with the Martello tower at the end of the esplanade built between 1806 and 1808. HM Land Registry put the Lewes district average at £368,408 in July 2026, with detached homes at £592,980 and flats at £197,656. Seaford is about 52 miles from our Portsmouth base as the crow flies, so East Sussex surveys and installs are planned visits. For the wider county see solar panels East Sussex. Inland, north of Lewes, we also cover solar panels Uckfield.

Do I need planning permission for solar panels in Seaford's conservation area?+
Usually not for panels on the roof slope of a house. The national planning register records the Seaford (Town Centre) conservation area with no Article 4 direction over it, and without one the roof slope keeps permitted development. The restriction applies to walls, balconies and roof enclosures fronting a highway; a flat-roof array needs prior approval first, and a listed building needs consent checked before design. We confirm the position for your address at the survey.
How much do solar panels generate in Seaford?+
PVGIS models about 4,668 kWh a year for a 4kW unshaded, south-facing array at a 35° pitch — roughly 586 kWh in June and 151 kWh in December. That is one of the higher figures on our patch, helped by the East Sussex coast.
