Solar Panels Hailsham: Installers for BN27
Solar, battery storage and EV charging in Hailsham — designed and installed by a local, MCS-certified team based in Portsmouth.
Quick answer
Hailsham (BN27) 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 4,680 kWh a year, higher than we modelled for Worthing (4,618) or Portsmouth (4,523).
Hailsham is a market town, chartered by Henry III in 1252, about 7 miles north of Eastbourne and the administrative centre of Wealden district. It has grown a great deal since 1945, with the northern part of the town now largely developed, and had 23,411 residents at the 2021 Census. The Cuckoo Trail cycle path follows the old Polegate to Heathfield railway through the town, and Michelham Priory, founded in 1229, is nearby at Upper Dicker.
For solar, the headline is sunshine. The EU's PVGIS model gives Hailsham one of the strongest yields of any town we have modelled. Hailsham is about 59 miles from our Portsmouth base as the crow flies, so we plan East Sussex surveys and installs as dedicated visits.
Solar in Hailsham: the local detail
Grid connection (DNO)
Hailsham is in the UK Power Networks (UKPN) area, like the rest of East Sussex: our postcode checks put BN27 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
Wealden District Council (offices on Vicarage Lane, Hailsham)
Heritage & conservation
Hailsham is one of Wealden's 33 conservation areas, and the council has published a draft character appraisal for it. Wealden's only conservation-area Article 4 direction covers part of Rotherfield, not Hailsham, so householder panels on a roof slope in Hailsham's conservation area normally keep permitted development; walls fronting a highway do not, flat-roof arrays need prior approval, and listed buildings need consent checked first.
Local housing stock
Much of Hailsham was built after 1945, with the northern side of the town largely developed since. HM Land Registry's July 2026 averages for Wealden were £391,211 overall, £592,872 for detached houses, £351,715 for semi-detached, £291,498 for terraced homes and £184,692 for flats.
Typical roofs
PVGIS 5.3 gives a 4kW unshaded array about 4,680 kWh a year facing south, 3,603 facing east and 3,694 facing west. A south-facing array here makes about 580 kWh in June and 158 kWh in December, and we check each roof for shading at the survey.
Sunlight & generation
PVGIS models about 4,680 kWh a year for a 4kW unshaded, south-facing array at a 35° pitch

Solar Panels Hailsham: Strong Yields, a Conservation Area Without an Article 4 and a UKPN Connection
Hailsham models as one of the sunniest places we cover. PVGIS 5.3 puts a 4kW unshaded, south-facing array here at about 4,680 kWh a year, with about 580 kWh in June and 158 kWh in December. East-facing it gives about 3,603 kWh and west-facing about 3,694 kWh, so west-facing roofs here out-produce east-facing ones slightly.
The planning picture is straightforward. Hailsham is one of Wealden District Council's 33 conservation areas, but Wealden's only conservation-area Article 4 direction covers part of Rotherfield, so panels on the roof slope of a house in Hailsham's conservation area normally keep permitted development. Walls, balconies and roof enclosures fronting a highway are excluded, a flat-roof array needs prior approval, and listed buildings need consent checked first.
Hailsham is on UK Power Networks' South Eastern network, so a battery or larger system needs a G99 application to UKPN before installation, which we submit. In Octopus's South Eastern region, Flux paid 29.79p per kWh for exports between 4pm and 7pm on 17 September 2026, 10.24p in the day and 5.05p between 2am and 5am; Outgoing Octopus pays 12p flat.
HM Land Registry's July 2026 average for Wealden was £391,211, with detached homes at £592,872 and semi-detached at £351,715. Our prices start from £4,995 for solar, £6,995 for solar with a battery and £12,920 for solar with a Tesla Powerwall 3, all subject to survey. We also cover Eastbourne, about 7 miles to the south.

Is there an Article 4 direction in Hailsham's conservation area?+
Not according to Wealden District Council, whose only conservation-area Article 4 direction covers part of Rotherfield. Panels on the roof slope of a house in Hailsham's conservation area are therefore normally permitted development, though flat-roof arrays need prior approval and listed buildings need consent checked first.
Why do solar panels in Hailsham generate more than in Cobham or Horsham?+
Mostly latitude and the sunnier coastal climate. PVGIS models a 4kW south-facing, unshaded array at about 4,680 kWh a year in Hailsham, against about 4,231 kWh in Horsham and 4,117 kWh in Cobham.
