Solar Panels in Cardiff
Solar panels on Cardiff homes
Cardiff has long rows of Victorian and Edwardian terraces in Roath, Canton and Cathays. Suburbs such as Whitchurch have interwar semis. Terraced roofs are often simple, so direction and shade decide how well they suit solar.
The city lies on the Severn Estuary, with a mild, damp climate. Panels run on daylight, so cloud is not a barrier. However, shade still matters, so a survey shows what each roof can make.
Housing across Cardiff
Roath and Canton have Victorian and Edwardian terraces, and Pontcanna has terraces and villas near the park. Cathays has many student lets in terraced streets. Because landlords own most of those homes, tenants need written permission.
Whitchurch has interwar semis with roomy roofs. Llandaff is a conservation area around the cathedral, so ask the council before you order there. Each district has its own rules and roof types.
Planning and the grid in Cardiff
Planning is devolved, so Welsh rules apply here rather than the English ones. Most house roofs can still take panels without a planning application. However, conservation areas and listed buildings need extra checks. Ask Cardiff Council if you are unsure.
A tenant needs the owner's written permission. Since the landlord carries the risk, they should check the insurance and the roof condition.
Because National Grid Electricity Distribution (NGED) runs the South Wales network, your installer files the connection paperwork.
Costs and support in Wales
VAT on fitting is 0% until 31 March 2027. Export income comes through the Smart Export Guarantee. Wales also has Nest, the Welsh Government's scheme. It offers free advice to anyone, and eligible households can get free improvements. Solar panels can be part of a package, but not for everyone.
Our guide to free solar panels explains who might qualify and how to check the latest rules. Rules change often, so confirm details with Nest before you apply.

Cardiff solar: common questions
What is Nest and can it help with solar in Cardiff?
Nest is the Welsh Government's scheme. It gives free advice to anyone in Wales. Eligible households can also get free improvements, and solar panels can be part of a package.
Do I need planning permission for solar panels in Cardiff?
Most house roofs do not. However, Welsh rules apply, and conservation areas and listed buildings need extra checks. Ask Cardiff Council to be sure.
Who runs the electricity network in Cardiff?
Because NGED runs the South Wales network, your installer handles the connection paperwork.
Are student houses in Cardiff suitable for solar?
Often yes, although the roof must be sound. The landlord must agree, and the two sides should settle who pays and who benefits.
Can I fit panels in Llandaff?
Possibly. Llandaff is a conservation area, so ask Cardiff Council first, and expect tighter rules for listed buildings.
Is Cardiff sunny enough for solar?
Yes, because panels use daylight. The south coast of Wales also gets reasonable sunshine, although roof direction and shade matter more than the city.
