Solar panels in Barnet: garden suburbs, old villages and the Suburb Trust

Barnet is a borough of suburban houses with large pitched roofs, which is good news for solar. What makes it different is where those houses sit. Much of its heritage is concentrated in planned garden suburbs and in old villages on the northern edge of London, and one of them, Hampstead Garden Suburb, has a second layer of control that has nothing to do with the council's planning rules.

Sixteen conservation areas, from Monken Hadley to Golders Green

Barnet Council's open data lists 16 conservation areas. They include Hampstead Garden Suburb, Monken Hadley, Totteridge, Mill Hill, Wood Street, Finchley Garden Village, Hendon The Burroughs, Golders Green and the Watling Estate.

Being in one of these areas does not automatically mean you need planning permission for solar. Under the national rules, the restriction in a conservation area or World Heritage Site applies to panels on a wall fronting a highway, not to a roof slope. Panels on a pitched roof, including a front roof slope, are normally permitted development as long as they sit no more than 0.2 m proud of the roof and below the ridge. Since 27 August 2026, a flat roof in a conservation area needs a short prior approval application to the council first. Listed buildings need planning permission and listed building consent. Our guide to planning permission for solar panels in London explains these rules in more detail.

Article 4 directions in Barnet

Barnet publishes 13 Article 4 directions covering parts of 10 conservation areas, plus two borough-wide directions on small houses in multiple occupation and agricultural land that do not affect solar. Most of the conservation area directions date from the 1970s and 1980s, before householder solar rights existed in 2008, so they cannot have removed them.

We read the two most recent directions we could open. The Finchley Church End direction of 2011 and the Mill Hill direction approved in April 2008 both cover a short list of named cottages, and both bring alterations to a roof slope facing a road, waterway or open space under control. Neither mentions solar or microgeneration. In practice that means roofing work on those properties may need permission even where the panels themselves would not. If your roof needs attention first, read whether you need a new roof before solar.

We also read the Totteridge direction approved in May 2008, which covers 17 to 27 Totteridge Village. It follows the same pattern, controlling roof slopes, extensions, porches, chimneys and boundaries that face a road or open space, and it does not mention solar. We still check the direction for each property before we quote.

Hampstead Garden Suburb: two sets of permissions

The Suburb is a conservation area with its own Article 4 direction, dating from 1971. It is also managed by the Hampstead Garden Suburb Trust, a charity that runs a scheme of management for the estate. Residents need the Trust's consent before changing the external appearance of their home, separately from anything the council requires. Solar on a Suburb roof therefore needs the Trust's agreement, even when the national planning rules would allow it. We suggest Suburb customers contact the Trust early, and we can supply the layout drawings and panel details it will want.

Flats and connecting to the grid

Since 27 August 2026, blocks of flats have permitted development rights for solar for the first time. The right belongs to the block, so it is the freeholder or management company that decides, not an individual flat owner.

The electricity network across Barnet is run by UK Power Networks. Most home systems are notified to them after installation, while larger systems or those with big batteries may need approval beforehand. We handle that paperwork, and our guide to DNOs and export limits explains how system size affects it.

Before we quote anywhere in Barnet, we check the designations for your address, including any Article 4 direction and listing. To get started, request a solar and battery quotation and we will look at your roof, your energy use and what applies to your street.
