Do solar panels need planning permission on the Wirral?

The basic rule for houses

In England, solar panels on a house are "permitted development": you can fit them without applying for planning permission, provided you keep to conditions set out in the national order, Schedule 2, Part 14, Class A. The order was amended on 27 August 2026, so older guides may be out of date. For panels on a pitched roof the key conditions are:

• the panels must not project more than 0.2 m beyond the plane of the roof slope;
• they must not be higher than the highest part of the roof, not counting the chimney;
• they should be sited, so far as practicable, to minimise their effect on the appearance of the building and the amenity of the area;
• they must be removed as soon as reasonably practicable when no longer needed.

On a flat roof the highest part of the panels may stand up to 0.6 m above the highest part of the roof, which allows them to be tilted on frames. Wirral Council's own guidance agrees that roof panels on a house or flat are "in most cases" permitted development, and suggests the rear of a building or an angled frame on a flat roof where you have the choice.

Summary of Part 14 of the national order as amended on 27 August 2026. Bromborough Pool's Article 4 direction can remove rights there.

Conservation areas: what changes

Wirral has 26 conservation areas, from Hamilton Square and Birkenhead Park to Caldy, Thornton Hough and West Kirby. In planning law these are "article 2(3) land", where some permitted development rights are narrower:

• Walls, balconies and roof enclosures that front a highway cannot have panels under permitted development. Wirral's leaflet for residents of conservation areas puts it as needing consent for panels on principal or side walls visible from the highway.
• Roof slopes, including front slopes, remain permitted development under the national rule for houses, within the 0.2 m and ridge limits and sited to minimise their effect on the street. Expect the council to prefer rear slopes, and all-black panels look quieter on a slate roof.
• A flat-roof array needs the council's prior-approval decision before work starts.

The full list, and what the Article 4 directions mean, is on our conservation areas page.

Article 4 directions

A council can make an Article 4 direction to remove particular permitted development rights in a defined area. Wirral's solar page says Bromborough Pool, the 1850s village built for the workers of Price's candle factory, is the only conservation area with one; its management plan keeps controls on roof coverings and roof features. The council's Article 4 page also lists older directions covering particular streets and sites, including some in Heswall and around Caldy and Thurstaston, without saying what each restricts. If you live in any of those places, ask the council before you rely on permitted development.

Listed homes, including Port Sunlight

There is no permitted development for solar panels on a listed house or on a building within its grounds. You need planning permission and listed building consent, and fitting panels without consent to a listed building is a criminal offence. Wirral has over 1,900 listed buildings, and nearly every building in Port Sunlight village is Grade II listed. Port Sunlight has a Local Listed Building Consent Order for 2025 to 2040 that lets residents carry out some small works without a separate application, but it covers rear doors and windows, yard gates and slim glazing, not solar panels or roof works. Talk to Wirral Council's conservation officers before you approach installers; the conservation areas page has more on Port Sunlight.

Panels in the garden

Stand-alone panels at a house, on the ground or on a frame in the garden, are permitted development under Class B if the panels total no more than 9 m² and keep to height limits: 1 m if they are within 5 m of the boundary and in front of the house, 2 m if within 5 m of the boundary, 2 m in a conservation area if nearer a road than the house, and 4 m elsewhere. In a conservation area, an array nearer a road than the house, or within 5 m of the boundary, needs the council's prior approval on its appearance first. These limits replaced the old rule of a single stand-alone panel on 27 August 2026. Wirral's solar page still describes the old rule, so if you are planning a garden array, quote the current order when you ask the council.

Flats and blocks of flats

Class A covers panels on a block of flats as well as a house, under the same roof conditions. The decision belongs to whoever controls the roof, usually the freeholder or management company. Stand-alone panels in the grounds of a block of flats keep the older, tighter limits. Small plug-in devices are now a separate option; see flats and plug-in solar.

Plug-in solar and wall panels

From 27 August 2026, plug-in solar devices with an output of up to 800 watts can be connected through an ordinary socket under new regulations, and the planning rules for panels on walls and balconies were rewritten the same day. Plug-in panels must not be fixed to a wooden fence, gate, wall or other enclosure. In a conservation area the ban on walls and balconies fronting a road still applies.

How to be sure

1. Check whether your home is listed or in a conservation area on Wirral Council's conservation area and listed building pages.
2. If it is neither and the panels go on the roof within the limits above, you do not need to apply.
3. If you want certainty, for example when selling later, you can apply to the council for a lawful development certificate, which confirms that the work is permitted development.
4. If your home is listed, in Bromborough Pool, or the panels would go on a road-facing wall in a conservation area, ask the council for pre-application advice before you get quotes.

Planning permission is separate from building regulations. The roof must carry the extra weight and the electrical work must be done and certified properly; an MCS-certified installer deals with both and gives you the certificates.
