Solar planning in Trafford: panels, conservation areas and permission
Solar panels in Trafford: the permitted development rules, Trafford Council's conservation areas and how to check yours, and the towns we cover there.
Trafford Council is the planning authority for Altrincham among the towns we cover. Whether panels on a house there need the council’s permission comes down to two things: the national rules for England, and whether the house sits in one of the council’s conservation areas or is listed.
Solar planning in Trafford: the rules that apply
In England, panels on a house are normally permitted development under Part 14, Class A of the General Permitted Development Order 2015, as amended on 27 August 2026. On a pitched roof they may stand no more than 0.2 metres proud and no higher than the roof’s highest point; on a flat roof the array may rise no more than 0.6 metres above it; on a wall, 0.2 metres where it abuts a highway and 0.4 metres elsewhere. A listed house has no such rights, and in a conservation area nothing may go on a wall, balcony or roof enclosure that fronts a highway; a flat-roof array on that land needs the council’s prior approval of its appearance first.
Conservation areas in Trafford
Trafford Council does not give a total on the page we read. Article 4 Directions can further restrict permitted development rights in specific areas within a conservation area.
Checking an address: The council maps its conservation areas. Read it on Trafford Council’s conservation-area page.
Each town we cover in Trafford has its own pages for solar panels in Altrincham, with that town’s own PVGIS figures, network and conservation areas.
The network side
Planning is one form; the network operator is another. The towns here are on SP Electricity North West, and every system is notified to the operator under G98 or, for larger systems, G99. Our guide to the G99 application covers it, the Greater Manchester page sets out the networks town by town, and the UK-wide rules are in our guide to whether solar panels need planning permission.
A car charger has planning rules of its own, which change in England on 21 October 2026: EV charging in Trafford sets them out with the council’s plug-in car and public charger figures.
If your house is listed, in a conservation area, or has a flat roof, tell us on the first call. It changes the design and sometimes the order things happen in, but rarely whether solar works.
