As the UK races to meet its net zero targets and curb its reliance on fossil fuels, solar panels have moved from being a niche investment to a mainstream solution. Across the country, towns and cities are embracing solar power not just as a way to reduce carbon emissions, but also to combat soaring energy bills and increase energy independence. But which UK towns are truly leading the charge?

Using publicly available data on solar adoption per household, community energy projects, and local council green initiatives, we’ve identified the UK’s top 10 greenest towns – the places where solar panels are powering a cleaner, more sustainable future.

How the Rankings Were Made

To identify the UK’s greenest towns, we analysed solar panel installation figures from the Microgeneration Certification Scheme (MCS), local authority clean energy projects, and solar adoption rates per 10,000 households. Towns were also assessed on factors such as support for green infrastructure, public solar incentives, and community-led renewable initiatives.

The result is a snapshot of where solar energy is truly taking root – not just where panels are installed, but where they are supported by wider environmental efforts.

Top 10 Greenest Towns in the UK

1. Brighton and Hove

Brighton leads the way with a high concentration of solar panels per household and strong council-led sustainability initiatives. The city also supports multiple community energy cooperatives, giving residents shared ownership of solar assets.

2. Exeter

Exeter benefits from a forward-thinking city council and well-developed local infrastructure to support renewables. It boasts an impressive solar energy output per capita and has invested in solar for council buildings and schools.

3. Bristol

As one of the first UK cities to declare a climate emergency, Bristol continues to push renewable energy. With community-owned solar farms and consistent funding support for homeowners, it earns a spot in the top three.

4. Milton Keynes

With a reputation for smart city innovation, Milton Keynes features solar panels on thousands of residential properties and several large-scale solar projects. Its green transport links also support its eco credentials.

5. Cambridge

This academic hub supports solar energy both at the university and community level. Numerous local schemes make it easier for homeowners to invest in renewables, and the city benefits from high annual sunshine hours.

6. Sheffield

Sheffield combines urban regeneration with sustainability, investing heavily in solar as part of its Net Zero strategy. Many public buildings, including leisure centres and libraries, now generate solar power.

7. Reading

A blend of private adoption and council incentives has made Reading one of the UK’s surprise solar success stories. Community awareness and take-up have rapidly accelerated since 2020.

8. Leeds

Leeds City Council has installed solar across schools, social housing, and commercial developments. A vibrant tech and energy innovation sector supports continued green growth.

9. Nottingham

Known for its district heating system, Nottingham has also expanded its renewable footprint with major investment in solar PV systems for social housing.

10. Norwich

This East Anglian city benefits from above-average sunshine and strong local take-up of solar. The city is home to several award-winning green housing projects using solar as a cornerstone of design.

What the Experts Are Saying

George Penny, Director of The Solar Co, says these results highlight a broader shift across the UK.

“We’re seeing real momentum in certain parts of the UK, where local policies and community interest are combining to accelerate the adoption of solar panels. It’s encouraging to see towns taking the lead – not only to save on bills, but to build a cleaner, more sustainable future. Solar power is no longer a fringe option – it’s fast becoming mainstream.”

What Makes These Towns Stand Out?

While these towns vary in size, location, and demographics, they share several common traits that contribute to their green success:

Local government support: Many have councils that actively invest in solar infrastructure or provide homeowner grants.

Community involvement: From energy co-ops to neighbourhood bulk-buy schemes, grassroots engagement is a major driver.

Integration with planning: Solar-ready housing developments and commercial spaces show long-term commitment.

Public awareness: Education campaigns and local case studies encourage residents to go green.

Together, these factors create fertile ground for solar energy to thrive.

A Blueprint for the Future?

The UK still has a long way to go in reaching its renewable energy targets, but these towns offer a model for what’s possible. With smart investment, community buy-in, and consistent policy support, solar power could help reduce emissions, stabilise the grid, and protect households from future price shocks.
