Do You Need Planning Permission for Solar Panels in South Yorkshire?

ElectriFusion Solutions · 15 October 2026

Usually not. Panels on the roof slope of a house in Doncaster, Sheffield, Rotherham or Barnsley are normally permitted development, which means no planning application, provided they meet a short list of conditions. The exceptions are listed buildings, flat roofs and highway-facing walls in conservation areas, and streets covered by an Article 4 direction. This is how each rule works, borough by borough, as of October 2026.

Where the rule comes from

Permitted development for solar on a house sits in Class A of Part 14 of the General Permitted Development Order (the version in force on legislation.gov.uk as re-read on 14 October 2026). Class A covers solar equipment on a dwellinghouse or a block of flats, and on a building inside its curtilage such as a garage. Ground-mounted arrays are a separate class with their own limits, so this guide is about roofs.

The conditions that matter for a pitched roof:

• the panels must not project more than 0.2 metres beyond the plane of the roof slope;
• they must not sit higher than the highest part of the roof, excluding any chimney;
• so far as practicable they are sited to minimise the effect on the external appearance of the building and on the amenity of the area;
• they are removed as soon as reasonably practicable when no longer needed.

A standard on-roof mounting system on a tiled or slate roof meets the first two conditions by design: the rail sits a few centimetres above the tiles and the panels follow the slope. In-roof (integrated) systems sit flush. Neither needs an application on an ordinary house outside the special cases below.

Conservation areas: roof slopes yes, highway-facing walls no

Inside a conservation area the roof-slope rules above still apply, so panels on the slope of the roof remain permitted development even if the roof faces the street. What Class A removes in a conservation area is the right to fix panels to a wall, balcony or roof enclosure that fronts a highway, and the right to put panels on a flat roof without first asking the council: a flat roof in a conservation area needs a prior-approval application (Class A, paragraph A.2(ba)) before work starts.

Each of the four boroughs has its own list:

• Doncaster: City of Doncaster Council has designated 46 conservation areas, including residential Bessacarr, and around 800 listed buildings. Its current Article 4 directions cover changes of use and demolition rather than roofs, so a roof-slope array in Bessacarr is still permitted development. Details on our solar panels Doncaster page.
• Sheffield: an exceptionally large number of conservation areas, including Broomhill, Walkley, Crookes, Hillsborough, Ringinglow and parts of Nether Edge and Sharrow. Two of them, Nether Edge (direction made in 2005) and Broomhill (2009), also carry Article 4 directions that withdraw some permitted development rights, so a house in either is checked against its direction before any position is agreed. See solar panels Sheffield.
• Rotherham: Rotherham Metropolitan Borough Council has designated 28 conservation areas. See solar panels Rotherham.
• Barnsley: Barnsley Metropolitan Borough Council is the planning authority, with 18 conservation areas across the borough. See solar panels Barnsley.

If you are not sure whether your street is inside one, each council publishes an online map; our surveyor checks it before quoting and tells you which rule applies to your roof.

Listed buildings

A listed building always needs listed building consent for solar panels, in a conservation area or not, because fixing panels to the roof alters the character of the building. That is a different application from planning permission and the council's conservation officer decides it. Some owners are refused; some are approved on a rear slope or an outbuilding. We will tell you honestly at the survey whether an application is worth making.

Article 4 directions

An Article 4 direction is a council order that removes specific permitted development rights in a defined area, usually to protect the character of a conservation area. Where one covers solar panels, a householder application is needed even for a roof-slope array. In South Yorkshire the directions we check most often are Sheffield's Nether Edge and Broomhill; Doncaster's current directions do not cover roofs. Rotherham and Barnsley are checked case by case against the council's list.

Flats, flat roofs and outbuildings

Class A applies to a block of flats as well as a house, but the freeholder's or management company's written consent is usually required before anything goes on a shared roof. Flat roofs outside a conservation area are permitted development within the same 0.2 metre and height limits; inside a conservation area they need prior approval first. A detached garage or outbuilding inside the curtilage of the house is covered by Class A in the same way as the house itself.

What is not planning: the grid and Building Regulations

Two other sign-offs are often confused with planning. The grid connection is handled with Northern Powergrid, the network operator for South Yorkshire: an inverter up to 3.68 kW per phase is notified after installation under G98, and anything larger needs a G99 application before the work starts. Building Regulations cover the electrical work and the roof's ability to carry the panels; as the installer we notify Building Control through our competent-person registration, so you do not apply yourself. Neither involves the planning department.

If you do need permission

A householder planning application goes to the borough council through the Planning Portal with a site plan, a roof plan showing the array, and elevations. We prepare the drawings from the survey. Decisions normally take eight weeks from validation. If a listed building is involved, the listed building consent application runs alongside it. Ask before you buy the kit: a refusal after installation can mean removal.

Fitting air conditioning as well? The outdoor unit has its own rules under Class G, with a noise test; they are set out in our air conditioning planning permission guide for Doncaster.
