Planning rules for solar in Whitstable
The general rule
Part 14 of Schedule 2 to the General Permitted Development Order gives householders in England the right to fit solar on a house roof without a planning application, within limits. On a pitched roof the panels must not stick out more than 0.2 metres from the roof slope, and must not rise above the highest part of the roof, not counting a chimney. A condition says they must be sited, so far as practicable, to minimise their effect on the building's appearance and on the amenity of the area, and removed when no longer needed.
Conservation areas near you
In a conservation area, or a World Heritage Site, solar must not be fitted to a wall, balcony or roof enclosure that fronts a highway. A roof slope that faces the road is not caught by that rule. Canterbury City Council's records on the national planning data platform list 98 conservation area records across the district, and by our reading seven of them cover parts of Whitstable: Whitstable Town, South Whitstable, Church Street, Tankerton, Chestfield, Courts Lee Manor and the Canterbury and Whitstable Railway with Whitstable Station. Whether your street is inside one needs a check of the council's map.
Listed buildings need listed building consent, and a council can restrict rights with an Article 4 direction. The council's advice can be stricter than the national rule, so ask.
Timber cladding and plug-in solar
This is new from 27 August 2026. For plug-in solar, permitted development does not cover a wooden wall, balcony or enclosure, or any part of a house clad in timber, and a freestanding kit cannot be fixed to a wooden fence, gate or wall. If your home is weatherboarded, a plug-in panel on that wall is not covered by the national rule. Our news page has the detail.
Flats and shared roofs
Flats have their own limits, including listed blocks, and you need the freeholder's agreement for a shared roof. We check this before a quote.
Network approval is separate
Planning is one thing, and the electricity network is another. UK Power Networks runs the local network. Small systems are notified after fitting (G98) and larger ones need approval first (G99). Your installer handles both.
Questions people ask
Do I need planning permission for panels on my roof in Whitstable?
Usually not, for a house roof in England, within the limits above. Conservation area, listed building and Article 4 cases need checking.
Can I put panels on the front roof slope?
In most cases yes. The conservation area wall rule does not apply to roof slopes, but siting should minimise the effect on appearance, and the council may advise differently.
Who do I ask?
