The national limits, in plain words
Solar on homes in England falls under Part 14 of the General Permitted Development Order: Class A for equipment on a house or a block of flats, Class B for a stand-alone frame in the grounds. Both classes were replaced by an amending order from 27 August 2026 (SI 2026/896). If the work stays inside them, no application is needed.
| Where on the house | In plain words |
|---|---|
| A pitched roof | Panels can stand out up to 0.2 m from the roof surface, and nothing may poke above the ridge (chimneys aside) |
| A flat roof | Up to 0.6 m higher than the roof's highest point, chimneys aside |
| A wall | Up to 0.2 m out where the wall is on a road, 0.4 m on other walls |
| A balcony or roof terrace enclosure | The same 0.2 m or 0.4 m, measured from the outside face |
| Conservation area | Nothing on a wall, balcony or enclosure facing a road; a flat-roof scheme needs the council's decision on prior approval before work starts |
| Listed building | Not covered at all: listed building consent is needed |
Equipment has to be placed, as far as practicable, so it does least harm to the look of the building and the area, and removed once it is no longer needed. Anything that met the rules in force before 27 August 2026 but not the new ones can still be installed under the old rules until the end of 26 August 2027. The Planning Portal summarises the change.
For a back-to-back the owned slope faces the street, so the panels are on the public side of the house by definition. Outside a conservation area that changes nothing; within one, roof panels inside the limits remain permitted development, but the duty to limit their visual effect is felt more on a street-facing slope.
Leeds conservation areas
The council lists 80 conservation areas across the Leeds district, 55 of them with appraisals and management plans (Leeds City Council). They range from the city centre to outlying villages. The council's page notes that permitted development rights are restricted in conservation areas and lists "some solar panels" among the works that need permission, alongside dormers, cladding and some chimneys and flues.
In practice the national order sets the line: roof panels within the limits are fine, panels on a wall, balcony or enclosure facing a road are not, and a flat roof needs a prior approval decision. Appraisals for individual areas can be useful for understanding what the council values about a street. Some owners ask for an informal view before committing.
Article 4: the one that is not about solar
An Article 4 direction lets a council take away specific permitted-development rights in an area. Leeds has one that people often ask about: it covers turning family houses into small shared houses in multiple occupation across parts of the city, including areas such as Headingley and Harehills (Leeds City Council). It controls a change of use. It does not remove the right to fit solar panels, and we found no Leeds direction that does. Directions can be made or changed, so the planning team is the authority for any particular street.
Listed buildings
Historic England counts 2,368 listed building entries in Leeds: 46 at Grade I, 104 at Grade II* and 2,218 at Grade II (Heritage Counts 2026). An entry can cover a single house or a whole row. Solar on a listed building, or on a building within its grounds, is outside permitted development altogether: listed building consent is needed before anything is fixed, and working without it is a criminal offence. Consent for panels out of public view is often possible but decided case by case.
Flats, plug-in panels and garden frames
The 2026 order includes separate Class A conditions for blocks of flats and excludes listed blocks. For flat owners, though, the first permission is the freeholder's or management company's, and the lease sets the terms; see shared houses and flats.
Plug-in panels became permitted development on the same date, except on a wooden wall, balcony or enclosure or anything clad in timber; a lease or tenancy can still forbid them. See plug-in solar in Leeds.
A stand-alone frame in the garden falls under Class B: at most 9 m² of panels, with height limits from 1 m to 4 m depending on how close it is to the boundary and whether it is in front of the house. In a conservation area, a frame closer to a road than the house needs prior approval, and none is allowed in the grounds of a listed building. Most terraced plots in inner Leeds have little room for one.
Five checks for your address
- Search the National Heritage List for England for your address.
- Check the council's conservation area maps and, if you are inside one, read its appraisal.
- Note which wall or slope the panels will use and whether it faces a road.
- For a flat, get the freeholder's written consent and read the lease.
- If you want certainty, apply for a lawful development certificate.
An MCS installer should design within the limits and say so in the quote; the installer checklist includes it. For costs, see what solar costs in Leeds.
