Planning permission for solar panels in Berkshire

Do you need planning permission for solar panels in Berkshire? For most houses, no. Roof panels on a house are permitted development, and since 27 August 2026 the conservation-area rule is narrower than many Berkshire owners expect. This guide sets out the exceptions for the four unitary councils our Berkshire pages cover, Reading Borough Council, Wokingham Borough Council, Bracknell Forest Council and the Royal Borough of Windsor and Maidenhead (which takes in Windsor, Maidenhead and Ascot), using the national rule alongside each council’s own conservation-area and Article 4 records, read on 19 October 2026. For what an installation itself involves, see our page on solar panels in Berkshire.

The short answer for Berkshire homes

The legal basis is the Town and Country Planning (General Permitted Development) (England) Order 2015, Schedule 2, Part 14, Class A, in the form amended by S.I. 2026/896 with effect from 27 August 2026. Class A makes solar equipment on a house permitted development, so no application is made, provided its conditions are met. A semi in Caversham, a detached house in Woosehill, a terrace in Crown Wood and a cottage in Clewer all start from that same text; what separates them is the designation layer on top, and Berkshire’s four councils have built very different ones.

Reading is the council where the Article 4 question matters most, because its directions name individual house numbers and remove every permitted development right at them. The Royal Borough is the council with the most conservation areas. Wokingham has 16 conservation areas, mostly in its villages, and a short list of Article 4 directions. Bracknell Forest has six conservation areas and a council web page whose wording on solar is wider than the 2026 Order. Each is taken in turn below.

The pitched-roof conditions, applied to Berkshire’s houses

Class A applies to houses, and Berkshire’s councils hold them in very different proportions. At the 2021 Census, 42.7% of Wokingham borough’s 69,165 households lived in detached houses and 29.2% in semis. Windsor and Maidenhead was 30.7% detached and 26.1% semi-detached. Bracknell Forest had the highest share of terraces of the four, 28.8%, and Reading the lowest share of detached homes, 12.2%, with 28.2% of households in terraces.

Take a Wokingham detached house with a south-west slope. The Order lets panels go on it if they stand no more than 0.2 m proud of the slope, stay below the highest part of the roof (chimneys aside), are placed so as to minimise their effect on how the building looks, and come off once they are no longer needed. Nothing in those conditions refers to which way a slope faces, so the road-facing slope of a Bracknell terrace is treated exactly as its back slope, unless a direction says otherwise. Panels on walls have separate limits: 0.2 m on a wall abutting a highway and 0.4 m on any other wall.

Conservation areas in the four council areas

Windsor and Maidenhead. The Royal Borough lists 27 conservation areas. Around Windsor they include Windsor Town Centre, Inner Windsor, Trinity Place and Clarence Crescent, Mill Lane in Clewer Village, Old Windsor and, across the river, Eton; near Ascot, Sunningdale; and in the villages, Datchet, Bisham, Hurley, Shurlock Row, Waltham St Lawrence and others. The Maidenhead areas, from All Saints at Boyn Hill to Pinkneys Green, are covered in our guide to planning rules for panels and a battery in Maidenhead.

Reading. Reading’s 15 conservation areas, on the government’s planning data platform, are Alexandra Road, Christchurch, Downshire Square, Eldon Square, Horncastle, Kendrick Road, Market Place and London Street, Redlands, Routh Lane, Russell Street and Castle Hill, St Mary’s Butts and Castle Street, St Peter’s, South Park, Surley Row and The Mount. Many are streets of Victorian and Edwardian brick terraces and villas, where siting deserves working out before anyone quotes.

Wokingham. Wokingham Borough Council lists 16: Arborfield Cross, Finchampstead Church, Hurst, Murdoch Road, two at Remenham (Henley Bridge and Church), Ruscombe, Sindlesham, Sonning, Swallowfield, Twyford Station, Twyford Village, Wargrave, Wokingham Town Centre and Langborough Road, and Woodley Green. Most are village cores; in the town itself, the town centre area around the Market Place and Murdoch Road are the two to check.

Bracknell Forest. The council lists six: Binfield (Wicks Green, designated in November 2018), Crowthorne, Easthampstead (where Point Royal stands), Warfield (Church Lane, the borough’s first), Winkfield Row (13 December 2005) and Winkfield Village (8 December 1977). The New Town neighbourhoods sit outside them, as our guide to whether a home battery needs planning permission in Bracknell explains.

Across all 64 of those conservation areas, the amended Class A excludes one thing only: equipment on a wall, balcony or roof enclosure that fronts a highway. Roof slopes are left alone, the street-facing one included, so a house in Redlands or Sonning keeps its roof-slope rights on the ordinary conditions unless it is listed or an Article 4 direction intervenes.

Flat roofs and garden panels

Flat roofs are common on Berkshire’s rear extensions and garages. On one, panels may rise no more than 0.6 m above the highest part of the roof. Where the house is in a conservation area, which the Order treats as article 2(3) land, the owner must also ask the council, before work starts, to decide whether it needs to approve the array’s appearance. For a flat-roofed extension in the Alexandra Road conservation area that request goes to Reading; for one in Inner Windsor, to the Royal Borough. It adds a step, not a likely refusal.

Ground-mounted arrays in a garden are Class B, a separate set of rules. The 2026 Order requires a prior-approval determination before work if any part of the array would be in a conservation area and closer to a highway bounding the garden than the nearest part of the house, or on article 2(3) land within 5 metres of the garden boundary. A large Wokingham or Ascot garden can make a ground array tempting; read Class B’s height and siting limits in full against the plot before planning one.

Listed buildings in Berkshire

A listed house is where the permitted development route stops. Class A does not apply to a listed house or to a building within its curtilage, so panels need listed building consent, and Historic England’s view is that consent is needed for any type of PV installation on a listed building. In Berkshire the best-known case is a block of flats: Point Royal in Easthampstead, the 18-storey tower of 102 flats built between 1961 and 1964 to a design by Arup Associates, is listed Grade II. In Ascot, Silwood Park, Alfred Waterhouse’s mansion of 1876 to 1878, is also Grade II. If your home is listed, start with the council’s conservation officer rather than an installer.

Article 4 directions, council by council

Article 4 directions are how a Berkshire council can switch permitted development off, street by street, and they are the only thing in this guide that can remove roof-slope rights from an ordinary house. Two points of reading matter. Each direction covers only the land and the classes it names, and taking away the right to alter a roof is not the same as taking away the separate solar right, so the text of the direction, not its title, decides. This is what each council publishes.

Reading. Reading Borough Council lists 15 directions protecting patterned brickwork and other architectural features, each on named house numbers: Basingstoke Road (St Leonard’s Terrace) 2 to 16 evens, Brisbane Road 3 to 27 odds, Field Road 3 to 49 odds, Jesse Terrace 1 to 35, Junction Road 23 to 31 odds, Katesgrove Lane 84 to 92 evens, Polstead Road 1 to 33 odds, Prince of Wales Avenue 48 to 54 evens, Rectory Road 8 to 32 evens and 1 to 17 odds, River Road 1 to 7, School Terrace 1 to 31, Shaftesbury Road 73 to 103 odds, Wantage Road 4 to 34 evens and Wokingham Road 1 to 19 odds. The council says these directions remove all permitted development rights, including extensions and other permitted works, so at those addresses roof panels need a planning application. Reading’s other directions, on small houses in multiple occupation, on 3 Craven Road and on new dwellings in commercial areas, do not touch householder solar.

Windsor and Maidenhead. The Royal Borough’s permitted development page lists its directions. The two that touch homes in conservation areas are Windsor Town Centre, where planning approval is required for the exterior painting of buildings in the defined area, and the Bray Conservation Area, where approval is required for most minor development to the front elevations of certain defined properties. The rest cover enclosures, agricultural buildings, caravans and changes of use from commercial to residential. None of the entries names solar equipment. If you own one of the defined Bray properties, ask the council whether front-facing panels fall within “most minor development” before any design is fixed.

Wokingham. Wokingham Borough Council lists seven confirmed directions: Monterey Roman Ride, Sandy Lane, Mill Lane in Sindlesham, Coombes Woodland, Whistley Woodland, Hennerton Backwater west of Wargrave Road, and land on the south side of Coombes Lane, Barkham. The texts are published as PDFs we have not read, so if you live in one of those places, ask the council what yours covers.

Bracknell Forest. We have not found a current list of Bracknell Forest’s Article 4 directions on the council’s site, and the government’s planning data platform records none for the council. The council’s records are the authority, so if you live in one of its six conservation areas, ask before work starts.

When a council’s guidance reads wider than the Order

Bracknell Forest Council’s page on planning in conservation areas lists, among works that may need permission, the installation of solar panels on a wall on the principal or side elevation of the house, or if visible from a highway. The Order as amended from 27 August 2026 is narrower: in a conservation area it excludes equipment on a wall, balcony or roof enclosure that fronts a highway, and leaves roof slopes on the ordinary conditions. The council’s wording may simply predate the amendment. Where guidance and the Order differ, the practical answer is the same as everywhere else in this guide: ask the council in writing before work starts, and keep the reply with your installation paperwork.

Flats, caravans and homes you rent

Flats change the question entirely. At the 2021 Census, 26.9% of Reading’s households lived in purpose-built flats and a further 4.8% in converted or shared houses, against 20.0% in Windsor and Maidenhead, 19.1% in Bracknell Forest and 11.0% in Wokingham. A leaseholder rarely owns the roof, so the freeholder’s consent and roof access come before planning, and the planning position for the block is one to confirm with the council. Bracknell Forest also had 842 households, 1.7%, living in a caravan or other mobile or temporary structure, where the householder rules above do not apply. And Reading’s 31.9% of households renting privately need their landlord’s agreement before anything touches the roof.

Building regulations, MCS and SSEN

Planning permission, or the lack of it, is only one of three checks on a Berkshire installation. Building Regulations are the second: Historic England notes that every PV installation must meet Parts A (structure), B (fire safety) and P (electrical safety), with the relevant council’s Building Control notified. On our side, we are NAPIT members (73495), hold MCS certification for solar PV and battery storage through NAPIT, and belong to the HIES Consumer Code (HCE/A/1392).

The third is the grid connection, which in Berkshire means one operator. On the licence-area boundaries in our battery data, the town centres of Reading, Wokingham, Bracknell, Windsor, Maidenhead and Ascot all sit in SSEN’s Southern Electric Power Distribution area, from about 6.6 km inside it at Ascot to 24.6 km at Reading, and SSEN’s registered office is at No.1 Forbury Place in Reading. The Energy Networks Association’s G98 rule covers systems up to 16 A per phase, 3.68 kW, notified before commissioning or within 28 days after it; anything larger needs a G99 application approved before work starts, and a 4 kW inverter, at 17.39 A, is just over the line. SSEN says it aims to answer fast-track applications within 10 working days. A battery added later goes through the same process, as our battery storage page explains.

Once planning is clear: the roof matters more than the town

Clear of planning, the roof decides the rest. Run on 19 October 2026 with PVGIS 5.3, the European Commission’s solar model, a 4 kWp array facing due south at 35° makes about 4,002 kWh a year in Windsor and about 3,959 kWh in Reading, the lowest of our six Berkshire towns. That gap of about 43 kWh is far below the ±148 to ±163 kWh by which any one town’s output swings from year to year (our arithmetic; PVGIS-SARAH3 2005–2023, 14% system losses). An east or west slope, a neighbour’s extension or a tall tree moves the answer more than a move from Bracknell to Windsor would. Our page on solar panel cost in Berkshire sets out how an installation is priced, the national figures line by line are on solar panel installation cost, and solar panel grants in Berkshire covers the income-linked schemes, which are a separate question from planning. For the 0% VAT rate that runs to 31 March 2027, see VAT on solar panels and batteries.

Where to check with your council

What to check before you ask for a quote

Before asking anyone to quote, work through four questions. Is the house listed, or inside one of the 64 conservation areas above? Is it at one of Reading’s Article 4 house numbers, or one of the defined Bray properties? Is the roof you have in mind pitched, flat, or not a roof at all but a garden? And, for a flat or a rented home, who else has to say yes?

At the survey, ask the installer to check those designations before anything is priced. We screen for a listed building, a flat roof in a conservation area, a highway-facing wall or balcony, and the Reading and Bray Article 4 addresses, and flag any of them before a quote is written so the council is asked first. Making any application is yours: we do not submit planning or prior-approval applications for customers. Town-level detail is on our pages for solar panels in Reading, solar panels in Wokingham, solar panels in Windsor and solar panels in Bracknell, and for what a Berkshire quote should itemise, see what is in a solar quote, line by line.
