Most Maidenhead households can fit roof panels and a home battery without a planning application, but “most” carries more weight here than in many towns. The Royal Borough of Windsor and Maidenhead lists 27 designated conservation areas, and the town and its riverside villages hold a good share of them. This guide explains what the national rules allow for panels, what they say (and do not say) about a battery, and where Maidenhead’s designations change the answer. For the battery decision as a whole, see our page on battery storage in Maidenhead.
Maidenhead’s conservation areas
RBWM’s register, which we read on 16 October 2026, names 27 conservation areas. Seven are in Maidenhead itself: All Saints at Boyn Hill, Altwood Road, Castle Hill, Furze Platt Triangle, Maidenhead Riverside, Maidenhead Town Centre and Pinkneys Green. Bray Village, Holyport, Cookham Village and Cookham Dean are close by. The council publishes a boundary map for each and has prepared appraisal statements for some, and its conservation team can confirm whether a particular address is inside a line. That check is the first step for any house in Boyn Hill, Castle Hill or the riverside streets.
Panels on the roof: the national rule
Roof-mounted solar on a house is permitted development under Schedule 2, Part 14, Class A of the General Permitted Development Order 2015, as amended by S.I. 2026/896 from 27 August 2026. On a pitched roof the panels must not protrude more than 0.2 m beyond the slope, must not sit higher than the highest part of the roof excluding chimneys, must be sited to minimise the effect on the building’s appearance and must be removed when no longer needed. Inside a conservation area, the only extra exclusion is equipment on a wall, balcony or roof enclosure that fronts a highway. Roof slopes keep their rights, front ones included, so a semi in the All Saints area whose best slope faces the road is judged on the same conditions as one whose best slope faces the garden.
Two Maidenhead situations need more. A flat-roof array on article 2(3) land, which includes conservation areas, needs an application for a prior-approval determination before work starts. And garden-mounted panels fall under Class B, with their own limits and a prior-approval step where they would sit in a conservation area nearer a bounding highway than the house.
What the rules say about a battery
Class A covers solar equipment and says nothing about batteries. The more useful rule is older: section 55(2)(a) of the Town and Country Planning Act 1990 says works that affect only the interior of a building, or do not materially affect its external appearance, are not development. A battery and inverter in a garage or a utility room will usually fall on that side of the line. A unit on an outside wall is a judgement about appearance, and on a street-facing wall in the Town Centre or Castle Hill areas that judgement deserves a word with the council before anything is fixed. Where a battery can go safely is a separate question, settled by the manufacturer’s instructions and the survey.
Listed homes
A listed house has no Class A rights, so panels need listed building consent, and Historic England says consent is required for any type of PV installation on a listed building. The battery is caught too: the Planning (Listed Buildings and Conservation Areas) Act 1990 requires consent for works that would affect a listed building’s character, and that is not limited to the outside. Fixings, cable routes and wall-mounted units inside a listed Maidenhead house belong in the consent conversation.
Article 4 directions
An Article 4 direction can remove permitted development rights street by street, and a direction that removes roof-alteration rights does not automatically remove the separate solar right: the direction itself has to be read. RBWM’s conservation-area page does not list its directions. A freedom-of-information request answered in May 2026 referred to directions for several places, including the Bray Conservation Area, and noted the requester had not found the documents online. We have not seen a direction that names householder solar or batteries in Maidenhead, but we have not seen every text either, so ask the council for your street.
Flats and the town centre
Purpose-built flats were 22.5% of Maidenhead households at the 2021 Census, and the Nicholson Quarter, approved in November 2025, will add 755 homes and 101 senior-living residences in the centre. In a block the planning question usually comes after the lease: roof, walls and plant space normally belong to the freeholder. Our guide to battery storage without solar panels covers the battery-only route that can suit a flat, and our guide to VAT on solar panels and batteries covers the 0% rate that runs to 31 March 2027.
Before the survey
Check the conservation-area map, whether the house is listed and whether any Article 4 direction applies. We screen for those at the survey, but the application, where one is needed, sits with you and the council. Our solar panels Maidenhead page covers SSEN connections and MaidEnergy, and the solar panels Berkshire hub covers the county.
