Can I install solar panels?
Mostly yes — roof-mounted solar panels are normally permitted development within limits. The basis is the GPDO 2015 (Part 14). On a roof or wall (Class A), panels are permitted if they protrude no more than 0.2m beyond the surface; on a pitched roof they must not sit above the highest part (excluding the chimney), and on a flat roof no more than 0.6m above it. They should be sited to minimise visual impact and removed when no longer needed. Stand-alone arrays (Class B) are limited to one per house, up to 9m², no dimension over 3m, max 4m high, and at least 5m from the boundary. Listed buildings need consent, and conservation areas restrict wall-mounted or street-visible panels. Building Regs apply for roof loading and electrics. In short: yes for most home roof installs, within the limits.
📋 The rules
- Roof/wall: panels protrude no more than 0.2m
- Pitched roof: not above the ridge; flat roof: max 0.6m above
- Sited to minimise visual impact
- Stand-alone: one per house, ≤9m², 5m from boundary
- Building Regs apply: roof loading and electrics
🔓 Exceptions
- Listed buildings need listed building consent (not PD)
- Conservation areas: not PD on a wall or where stand-alone is street-visible
- Article 4 directions can remove permitted development
⚠️ Penalties & fines
If a planning application is needed, the England householder fee is £548, while listed building consent is free. Installing over the limits or without the consent you needed can lead to an enforcement notice requiring removal (a criminal offence to ignore), and a listed-building breach is prosecutable. Building Regulations cover the roof safely carrying the load and the electrical work, usually self-certified by an MCS-registered installer. Beware a myth: "all solar panels need planning permission" is false — the large majority of domestic roof installs are permitted development with no application; needing permission is the exception (listed buildings, some conservation-area positions, or oversized arrays). Note the rules were expanded in 2023–2025, and further changes (the Future Homes Standard / solar on new homes) are pending. Before installing: use an MCS-accredited installer, keep within the 0.2m / ridge limits, and check whether your home is listed or in a conservation area.

❓ Frequently asked
Do I need planning permission for solar panels?
Usually not. Most domestic roof-mounted solar installations are permitted development and don't need planning permission, as long as the panels protrude no more than 0.2 metres beyond the roof, don't sit above the ridge on a pitched roof, and are sited to minimise their visual impact. Listed buildings and some protected positions are exceptions.
What are the limits for roof solar?
On a pitched roof, panels must not project more than 0.2 metres beyond the roof plane and must not be higher than the highest part of the roof, excluding the chimney. On a flat roof, they can be up to 0.6 metres above the roof. Beyond these limits, you'd need to apply for planning permission.
Can I put solar panels on a listed building?
Not as permitted development. Solar panels on a listed building need listed building consent, and usually planning permission too, because of the impact on the building's special character. In conservation areas, wall-mounted panels or panels visible from the street may also fall outside permitted development and require an application.
Do solar panels need Building Regulations?
Yes. Building Regulations apply to ensure the roof can safely carry the additional load of the panels, under the structural requirements, and that the electrical installation is safe and certified under Part P. In practice, an MCS-registered installer usually handles compliance and self-certifies the electrical work on your behalf.
Do all solar panels need permission?
No, that's a myth. The large majority of home roof solar installations are permitted development and need no planning application at all. Permission is the exception, required mainly for listed buildings, certain conservation-area positions, stand-alone arrays over the size limits, or where an Article 4 direction has removed permitted development.
