Solar Panels in Ealing: Costs, Planning, and Local Advice

Ealing sits in west London, bordered by Hounslow to the south and Harrow to the north. It is characterised by substantial Edwardian and late-Victorian terraced housing — solid brick buildings with pitched roofs, built to house the workers and professionals who moved to the suburbs when the District and Great Western railways expanded westward. This heritage housing stock, while attractive, comes with both opportunities and constraints for solar.

Solar in Ealing

Ealing's housing is varied: Edwardian terraces in Acton and Hanwell, larger semis in Greenford and Northolt (which became London suburbs in the 1930s), and more modern estates further west. The Edwardian terraces are the defining type — these are typically 3-bed, with a rear roof that may be south-facing depending on the street's orientation.

Typical system sizes:

• Edwardian mid-terrace (Acton/Hanwell): 2.5–4 kWp (6–9 panels), depending on roof orientation
• Edwardian semi-detached: 4–5 kWp (9–11 panels)
• 1930s semi or detached (Northolt/Greenford): 4–5 kWp
• Modern estate property: 3–5 kWp

If your terrace runs east–west rather than north–south, the rear roof may face north — ask your installer about split east-west systems, which can generate better overall yield than forcing all panels onto a partially shaded north-facing slope.

Costs and savings

Ealing sits in the mid-range of London installation costs — below inner London but above the England average.

Prices include 0% VAT on supply-and-install, valid to 31 March 2027.

Average property values in Ealing sit in the £500,000–700,000 range for a semi-detached, with areas like Ealing Broadway and Pitshanger commanding premiums. At 4–8% property value uplift from solar, a £600,000 home could see £24,000–48,000 added in value — favourably compared to a £6,000–7,500 installation.

Planning in Ealing

Most Ealing properties can install solar under permitted development rights without planning permission, provided panels do not protrude more than 0.2 m from the roof surface and the property is not listed.

Conservation areas: Ealing has a significant number of conservation areas, including Ealing Broadway, Pitshanger Village, Walpole Park, and parts of Acton Green and Bedford Park (shared with Hounslow). Within these areas, panels on roof slopes facing the highway require a full planning application. Panels on rear roofs are typically still permitted development.

Bedford Park — the late-Victorian planned suburb on the Ealing/Hounslow boundary — is a particularly notable conservation area with strong character. Speak to Ealing Council's planning team before installing here.

Local schemes

Ealing Council has participated in the Warm Homes Local Grant scheme for eligible households. Check Ealing Council's environment and housing pages for current funding availability.

The national ECO4 scheme (to December 2026) and the emerging Warm Homes Plan apply to eligible Ealing households. ECO4 requires qualifying heating measures alongside solar and is income-tested.

Solar installers in Ealing

A number of MCS-certified installers cover the Ealing area. Joju Solar operates across west London and the South East, with experience of the Edwardian and interwar housing stock that defines much of Ealing — from Acton terraces to larger semis in Northolt and Greenford. National installers including Octopus Energy Solar, Sunsave, British Gas Solar, and EDF Solar are also active in the area and should feature in your comparison.

When choosing an installer, verify their MCS certification, arrange a site survey before accepting any quote, and collect at least three quotes to compare costs and system designs.
