Do you need planning permission for solar panels?

Check your home with our planning checker

Answer a few questions about your home and where the panels will go. The checker applies the rules for your nation from the table above and says whether the panels look like permitted development, need a prior approval application or a planning application, or need a word with your council first.

Do you need planning permission for solar panels on your roof?

Not for most homes, the Energy Saving Trust says [21]. Solar panels on a house roof count as permitted development in England, Wales, Scotland and Northern Ireland, which means planning permission is granted by law, as long as every limit and condition for your nation is met [1][5][7][9]. The limits cover how far panels stand out and how high they go: on a pitched roof in England, Wales and Northern Ireland they cannot rise above the highest part of the roof, while Scotland allows up to 1 m from the roof plane or ridge [1][5][9][7]. In England a flat roof on protected land also needs a prior approval application first [1]. The Planning Portal still advises checking with your council that all the limits and conditions will be met [16].

The same rights can be taken away for a particular home or area. In England, a condition on the planning permission for your house can remove them, and a council can make an Article 4 direction so that an application is needed in a named area [4]. The Welsh Government says the same of Wales, and that Article 4 directions are most common in conservation areas [6].

What changed in England on 27 August 2026?

New rules for houses in England took effect on 27 August 2026 [2]. Panels can now stand out further from a wall, balconies and roof parapets get a limit of their own, and garden arrays have new height rules. Blocks of flats are largely unchanged, and the government has no plans to issue specific guidance on the change [3].

Work that was permitted under the old rules but is not under the new ones can still go ahead until the end of 26 August 2027 [2]. Garden arrays are covered in detail in ground-mounted solar panels.

Can I install solar panels without planning permission?

Yes, if the installation is permitted development: that is a planning permission granted by law, so no planning application is made. In England a few cases also need a prior approval application before work starts (see below) [1]. If any limit is not met, the work is not permitted development and the route is a planning application; in England an application for a change to a house costs £548 [14]. In England, when you are not sure, a lawful development certificate, a legal document from the council on whether the proposed work would be lawful, settles it [15], for half the full fee [14]: £274 for a change to a house, by our calculation. Another route is to change the plan instead: a different roof slope, panels closer to the roof or a smaller garden array can bring the work back within the limits.

Can you have solar panels in a conservation area?

Yes, within extra limits that differ by nation. In England, panels in a conservation area cannot go on a wall, balcony or roof enclosure that fronts a highway, a flat-roof installation on protected land needs a prior approval application before work starts, and a garden array nearer the highway than the house is limited to 2 m and needs one too [1]. In Wales the bar is on a main or side wall, or an outbuilding wall, fronting a highway, and on a garden array between the house and the highway [5]. In Scotland panels cannot go on the principal elevation of the home, or on a side elevation that fronts a road, and a garden array is not permitted development at all [7]. In Northern Ireland, a roof slope or wall that faces and is visible from a road is ruled out, and so is a flat-roof installation visible from a road [9].

Protected land in England (called article 2(3) land in the law) means conservation areas, areas of outstanding natural beauty, the Broads, National Parks, World Heritage Sites and certain areas named under the Wildlife and Countryside Act 1981 [4]. Your council can tell you whether your home is in one.

Can you put solar panels on a listed building?

Not without an application. In England, permitted development does not cover a listed house, any building in its grounds, or a garden array in its grounds [1], and works that would affect a listed building's character as a building of special architectural or historic interest need listed building consent [11]. The planning rules make no exception by grade, so grade 2 listed buildings are covered too [1]. In England there is no fee for listed building consent [14]. The Welsh Government says installation on a listed building in Wales will require planning permission and is likely to need listed building consent [6]. Scotland has the same consent rule as England [12], and its permitted development does not cover a listed building or its grounds [7]. In Northern Ireland, unauthorised works that affect a listed building's character are an offence [13], and permitted development applies in the grounds of a listed building only once listed building consent has been granted [9].

Two separate consents. Listed building consent protects the building's character; planning permission covers the development. A listed home can need both, and in England listed building consent has no fee [14].

Do you need planning permission for solar panels on a flat roof?

Not if the panels stay within your nation's height limits. In England panels can rise up to 0.6 m above the highest part of a flat roof [1]. The other nations measure from the plane of the roof: in Wales panels must sit at least 1 m in from the edge and no more than 1 m above it [5]; in Scotland the 1 m limit from the roof plane applies [7]; in Northern Ireland they can rise up to 1.5 m [9]. In England, a flat roof on protected land needs a prior approval application first [1]. Design and layout are covered in solar panels on a flat roof.

Do you need planning permission for ground-mounted solar panels?

Not if the array stays within your nation's limits, which are tighter than for roof panels. In England a house can have up to 9 sq m of panels in each garden array [1]. Heights run from 1 m to 4 m, depending on how close the array is to the boundary and the front of the house [1]. Wales allows one array of up to 9 sq m of panels [5]; Northern Ireland one of up to 14 sq m, measured for the whole installation rather than the panels [9]; Scotland treats a garden array as general garden works, with a 3 m height limit and no permitted development in conservation areas [8][7]. Ground-mounted solar panels works through how many panels fit and when the garden is worth it.

What is prior approval, and how long does it take?

Prior approval is a short check by an English council of how the panels will look, in place of a full application. Where it applies, you must apply before work starts. It covers a flat-roof installation on protected land, a garden array in a conservation area nearer the highway than the house, and a garden array on protected land within 5 m of the boundary [1]. The steps [1]:

1. Apply with a description of the work, a plan and the fee: £249 for the cases the fee schedule lists [14].
2. Neighbours are told by a letter or a site notice shown for at least 21 days.
3. Start work once the council says approval is not needed, gives approval, or 56 days pass without a decision.

Flats, rented homes and removed rights

Flats have their own rules. In England a block of flats keeps the older 0.2 m limit on walls and pitched roofs, and nothing is permitted on a listed block [1]. In Wales the rights apply to houses, and the Welsh Government advises people in flats to ask their council [6]. In Scotland the roof rules cover flats as well as houses [7]. In Northern Ireland the rights are written for a dwellinghouse, which the order says does not include flats [10], so ask the council. Planning is not the only consent: for plug-in solar, the government expects some people will need permission from their landlord, freeholder or property management organisation [3]. If your home was built under a planning permission, check whether a condition removed permitted development rights [4][6].

Do you need building regs for solar panels?

Building regulations (building regs) are a separate system from planning. They normally apply to roof panels in England and Wales: the roof's ability to carry the weight must be checked and proven, sometimes with strengthening, and the electrical work is covered too [17][20]. The Planning Portal advises asking an installer, preferably one who belongs to a Competent Person Scheme [17]. When you check an MCS installer, ask whether it is also registered with one: a registered installer can self-certify the work its scheme covers instead of you getting building regulations approval. The schemes are authorised by the UK government for England [18] and by the Welsh Government for Wales [19]. In Scotland and Northern Ireland, ask your council's building standards or building control team.

How to check your home before you sign

Is planning permission required for solar panels on your home? Work through these five checks.

1. Find your nation's rules in the table at the top; English rules do not apply in Wales, Scotland or Northern Ireland.
2. Ask your council whether your home is listed; whether it is in a conservation area, World Heritage Site, National Park, area of outstanding natural beauty or the Broads; whether an Article 4 direction applies; and whether its planning permission removed permitted development rights.
3. Measure the plan against each limit: how far the panels stand out, their height, and for a garden array its area and distance from the boundary.
4. In England, apply for prior approval where the rules require it (a flat roof on protected land, and some garden arrays), and for a lawful development certificate if you want certainty in writing.
5. Ask the installer to say in the quote which planning route the work relies on.

How a solar installation goes from survey to switch-on is in solar panel installation; prices by system size are in solar panel costs.
