Planning permission for solar panels on care homes

Planning permission for care home solar is one of the first questions an operator asks and one of the most often answered wrongly, usually because the householder rules get applied to a non-domestic building. A care home that provides personal care is not a house or a block of flats, so in England its rooftop solar sits under a different class of permitted development with different limits. This guide sets out those limits exactly as the legislation states them, the cases that fall outside them, and what changes for retirement blocks and in Scotland.

The default in England: Class J permitted development

Class J of Part 14 of the Town and Country Planning (General Permitted Development) (England) Order 2015 permits the installation, alteration or replacement of microgeneration solar PV or solar thermal equipment on a building, and other solar PV equipment on the roof of a building, other than a dwellinghouse or a block of flats. That is the class a residential or nursing home uses. Development is not permitted by Class J if:

• the equipment is on a pitched roof and would protrude more than 0.2 metres beyond the plane of the roof slope (paragraph J.1(a));
• the equipment is on a flat roof and its highest part would be more than 1 metre above the highest part of the roof, excluding any chimney (J.1(b));
• the equipment would be installed on a roof and within 1 metre of the external edge of that roof (J.1(c));
• the site is a scheduled monument (J.1(e)); or
• the building is listed, or within the curtilage of a listed building (J.1(f)).

Wall-mounted microgeneration equipment has its own limits under J.2: no more than 0.2 metres proud of the wall, not within 1 metre of a junction with another wall or the roof, and — on article 2(3) land such as a conservation area or National Landscape — not on a wall that fronts a highway. Two conditions attach to everything built under Class J (J.4(1)): the equipment must, so far as practicable, be sited to minimise its effect on the external appearance of the building and the amenity of the area, and it must be removed as soon as reasonably practicable when no longer needed.

Above 50 kW: the prior approval step

Class J separates microgeneration equipment from other solar PV equipment on the roof. Microgeneration is defined by section 82 of the Energy Act 2004 as generating capacity of up to 50 kilowatts of electricity. A care home roof array larger than that is still permitted development under Class J(c), but only after the developer has applied to the local planning authority for a determination of whether prior approval is required as to the design or external appearance of the development — "in particular the impact of glare on occupiers of neighbouring land" (J.4(2)). The application needs a written description, a site plan and the developer's contact details, and the authority can refuse it where the proposal does not comply with Class J or the information is insufficient (J.4(3)–(4)). Build this into the programme: work cannot start until the determination is made.

Listed care homes and heritage settings

A material share of the care home estate is converted period property, and some of it is listed. Class J does not apply to a listed building or anything within its curtilage, so an array there needs listed building consent and, in most cases, planning permission. The National Planning Policy Framework, republished on 17 August 2026 with lettered policies, is the framework those applications are now decided under:

• Policy CC2 (paragraph 2) directs decision-makers to give substantial weight to the benefits of improving the energy efficiency of existing buildings and drawing energy from renewable and low-carbon sources.
• Policy HE6 (paragraph 4) requires harm to the significance of a designated heritage asset to be weighed against the public benefits of the proposal.
• Policy DM1 (paragraph 2) notes that pre-application engagement may be required where proposals raise complex matters such as effects on heritage assets.

In practice that means a low-profile layout on the least visible roof slope, a heritage statement that describes the significance of the building and why the array does not harm it, and an early conversation with the conservation officer. Any page still citing "NPPF paragraph 2xx" for solar is citing the superseded framework.

Retirement blocks are a different class

Because Class J excludes blocks of flats, a retirement development of self-contained flats does not use it. It falls under Class A — the domestic class — which has its own separate limits and, like Class J, does not extend to listed buildings. The distinction follows the building, not the operator: a home providing personal care is non-domestic, a block of retirement flats is a block of flats. If you run both, check each site separately. The funding and consultation differences for retirement blocks are covered in our guide to solar panels for retirement homes.

Scotland: Class 6J with no capacity cap

Scotland has its own permitted development regime. Under Class 6J, set out in Annex C of Scottish Government Planning Circular 2/2024, building-mounted solar on non-domestic premises is permitted with no capacity cap — the previous 50 kW limit was removed on 24 May 2024 — provided no part protrudes more than 1 metre from the building surface. It does not apply to listed buildings, World Heritage Sites or National Scenic Areas, or within 3 km of an aerodrome; in a conservation area, panels may not go on the front elevation or a road-facing side elevation. Free-standing arrays under Class 6N are limited to 12 m², so any real ground array needs an application. Wales and Northern Ireland run separate regimes again — check with the local planning authority before relying on permitted development there.

Planning is not the grid connection

Permitted development settles whether you need planning consent; it says nothing about connecting to the network. Every array also needs the right connection route with your distribution network operator, and larger systems need a formal application that can take longer than the planning step. Treat the two as parallel workstreams. For the other compliance checks that belong alongside planning — the fire risk assessment, CQC Regulation 15 and your insurer — see fire safety and insurance for care home solar; for leased premises, the MEES and EPC position; and for the sector-specific case, solar panels for nursing homes.

Frequently asked questions

Do care homes need planning permission for solar panels?

In England, usually not. Rooftop solar on a care home — a building other than a house or a block of flats — is normally permitted development under Class J of Part 14 of the General Permitted Development Order, provided it stays within the Class J limits and the building is not listed. Arrays above the 50 kW microgeneration threshold still need a prior approval application before work starts.

How far can solar panels stick up on a care home roof?

On a pitched roof, no more than 0.2 metres beyond the plane of the roof slope. On a flat roof, the highest part of the equipment may be no more than 1 metre above the highest part of the roof, excluding chimneys. Panels must also be at least 1 metre from the external edge of the roof. These are the non-domestic Class J limits; the householder limits are different.

Can you put solar panels on a listed care home?

Not under permitted development: Class J does not apply to a listed building or a building within the curtilage of one. You will need listed building consent and usually planning permission. Under the National Planning Policy Framework republished in August 2026, harm to a heritage asset is weighed against the public benefits of the proposal, and pre-application engagement is recommended where heritage assets are affected.

Is a retirement block treated the same as a care home for planning?

No. Class J covers buildings other than houses and blocks of flats. A retirement development of self-contained flats is a block of flats, so it falls under Class A (domestic premises) with its own limits. A home providing personal care uses Class J.

Are the rules different in Scotland?

Yes. In Scotland non-domestic rooftop solar is permitted development under Class 6J with no capacity cap, provided no part protrudes more than 1 metre from the building surface. It does not apply to listed buildings, World Heritage Sites or National Scenic Areas, or within 3 km of an aerodrome, and in a conservation area panels may not go on the front elevation or a road-facing side elevation.
