Two of the South West's most desirable places to live — Bath and Cheltenham — are also two of the most heavily protected in terms of heritage conservation. Bath is a UNESCO World Heritage Site with over 5,000 listed buildings; Cheltenham has more than 2,500 listed buildings and one of the largest Regency conservation areas in England. If you live in either city, you may have assumed solar panels are impossible. They are not — but there are specific rules to understand and navigate.
The Basic Rule: Conservation Areas vs Listed Buildings
It is important to distinguish between two different types of protection:
- Conservation area: A designated area of special architectural or historic interest. Solar panels in conservation areas fall under modified Permitted Development rules — they can generally be installed but must not be visible from a highway or public space.
- Listed building: A building of special architectural or historic interest, specifically listed by Historic England. Installing solar panels on a listed building requires Listed Building Consent in addition to any planning permission. This is a higher bar.
Many homes in Bath and Cheltenham are in conservation areas but are not listed buildings. These properties have more flexibility for solar than listed buildings, though the conservation area rules still apply.
Solar Panels in Conservation Areas: Permitted Development Rules
Within a conservation area, solar panels can be installed under Permitted Development (no planning permission required) provided:
- Panels are not installed on a wall or roof slope that faces a highway (this includes any road, footpath, or public right of way)
- Panels do not protrude more than 200mm above the roof surface
- Panels are not higher than the highest point of the roof
- The building is not a listed building (which requires separate Listed Building Consent)
In practice, this means that rear-slope and hidden-slope installations are typically possible without planning permission even in conservation areas. A Georgian terraced house in Bath's central conservation area can often have panels installed on its rear roof slope — which faces a garden, not a highway — without any planning application.
Bath: UNESCO World Heritage Site Considerations
Bath's UNESCO World Heritage Site status adds an additional layer of sensitivity, but it does not create additional legal planning restrictions beyond the standard conservation area rules. The UNESCO designation means Bath & North East Somerset Council takes conservation particularly seriously, but the same Permitted Development rules apply.
Bath has approximately 5,000 listed buildings, many of which are Grade I or Grade II* (the highest levels of protection). For these properties, Listed Building Consent is required and the council will carefully consider the impact on the historic fabric of the building. However, Bath & NES Council has granted consent for well-designed solar installations on listed buildings where the panels are sympathetically placed on hidden roof slopes and the installation method avoids damage to historic materials.
Bath also participates in the Solar Together West of England scheme, which has helped many Bath homeowners — including those in conservation areas — access subsidised solar installations.
Cheltenham: Regency Conservation Area
Cheltenham's central conservation area covers much of the Regency town, including the Promenade, Montpellier, Pittville, and Lansdown districts. With over 2,500 listed buildings — the highest proportion of any town in England — Cheltenham presents similar challenges to Bath.
However, Cheltenham also has many streets and suburban areas that are within conservation areas but where the properties themselves are not listed. In these areas, rear and side roof slope installations are typically achievable under Permitted Development. Properties in Hester's Way, Benhall, Charlton Kings, and Leckhampton are often not in conservation areas at all and have no additional planning restrictions.
D&R Energy has successfully installed solar panels on Cheltenham properties in conservation areas, working closely with the local planning department to design sympathetic installations that satisfy both the homeowner's energy goals and the conservation officer's requirements.
Tips for Getting Solar Approved in Conservation Areas
- Check your property's listing status first. You can search Historic England's listed buildings register online. Many properties in conservation areas are not listed.
- Use a rear slope where possible. Rear-slope installations avoid the highway-facing restriction and are almost always acceptable in conservation areas.
- Choose low-profile panels. Modern all-black panels with minimal frames are more sympathetic to historic buildings than traditional blue framed panels.
- Use experienced installers. D&R Energy has navigated conservation area requirements across Bath, Cheltenham, Clevedon, and other protected areas. We can advise on what is achievable before you commit.
- Apply for a Certificate of Lawfulness. If you are unsure whether your installation qualifies as Permitted Development, a Lawful Development Certificate from the council provides certainty at a cost of approximately £200.
Solar panels in conservation areas are absolutely achievable with the right design and installer. D&R Energy serves homeowners across Bath and Cheltenham. Call 0800 772 0758 for a free consultation on your specific property.
