Introduction
Solar panels are a popular solution for homes and businesses that want to generate their own renewable electricity, reduce their carbon footprint, and lower their energy bills. However, when it comes to listed buildings, things are more complex, with tighter regulations and additional steps to consider.
We take you through everything you need to know about staying compliant when planning your solar panel installation on listed buildings, so you can make the most of renewable energy without compromising your property’s character.
What is a Listed Building?
The definition of a listed building, according to Historic England, is “a building of special architectural or historic interest with legal protection.” This means that the property is recognised for its significance and is protected by law to preserve its character, appearance, and heritage.
As a result, any alterations, whether internal or external, that could affect its historic or architectural importance typically require listed building consent. This includes changes that might seem minor, such as installing solar panels, as they can impact the building’s overall appearance.
Benefits of Solar Panels for Listed Buildings
There are lots of benefits of solar panels for listed buildings, both financial and environmental.
Lower energy bills
Many listed buildings have high energy bills due to the building fabric having poorer insulation or ventilation than newer builds. Installing solar panels on listed buildings lets you generate your own energy on-site. A well designed and maintained solar panel system typically has a lifespan of around 25+ years with a payback period of ~5 years. This means long-term savings on your energy bills and a very healthy return on investment
Improved sustainability
Solar panels are a great way to cut your scope 2 emissions, lowering your overall carbon footprint without having to conduct invasive work or altering your building’s structure. Better yet, when solar panels are installed properly on listed buildings, the roof and building can be returned to its original condition and therefore considered as a temporary lifespan.
Energy independence
The energy market is very volatile, and price spikes are common, so relying solely on the grid for energy can present additional risks. When you generate your own energy, you can reduce your reliance on the grid, benefitting from greater control over your energy and protecting your organisation during times of volatility.
Boost property value
Solar panels on listed buildings have the potential to increase the value of your property and make it more attractive to environmentally conscious buyers. As energy efficiency becomes a growing priority, properties that can demonstrate lower running costs and sustainable features often stand out in the market.
Modernise and future-proof your property
Solar panel installation can help bring a listed building in line with modern energy standards whilst preserving its historic character. By integrating renewable technology, you can ensure your building remains practical and efficient for years to come, making it better suited to meet future regulations.
Can You Put Solar Panels on a Listed Building?
The simple answer is – yes, you can put solar panels on a listed building, but it’s not as straightforward of a process as with a standard property. This is because listed buildings’ historical and architectural features are protected, so you will need to follow specific regulations and obtain the necessary permissions before going ahead.
This means applying for full planning permission with listed building consent, and in most cases accompanied by a heritage statement. The key is to ensure that any installation does not negatively impact the building’s character or appearance.
Staying Compliant When Installing Solar Panels on Listed Buildings
There are a number of steps you should take before installing solar panels on a listed building to ensure you have obtained all the relevant permissions, and your project can progress safely and compliantly.
Obtain Listed Building Consent (LBC)
Before any installation, you must apply for consent from your local planning authority to ensure your plans won’t harm the building’s historic character. You can apply for Listed Building Consent via your local planning authority, which generally takes around six to eight weeks. The key requirements for LBC are minimising visual impact, using reversible installation methods and demonstrating structural safety, both during installation and use. Approval may also depend on the building’s grade (I, II, or III).
Standard Planning Permission
When installing on a listed building, full standard planning permission will be required, as well as LBC. This is particularly relevant if the solar panels are visible from public areas or alter the character of the building’s exterior. Typically, planning permission and LBC can be completed in one application . Local planning authorities will assess the impact on the surrounding area, as well as any potential effects on the building’s architectural features. Even if listed building consent is granted, it is not guaranteed that planning permission will be granted too. Therefore, it’s recommended that you consult with the local authority early in the process to clarify whether full planning permission is required.
Use Discreet Installations
Try to position solar panels on listed buildings where they are least visible, such as the rear of the building or on flat roofs. This helps preserve the building’s historic character and improve your chances of LBC and planning permission approval whilst still generating as much solar power as possible. Flat roofs are especially great candidates for solar panels, as they are installed via a non-penetrative mounting system which can very easily be installed and removed without any impact on the roof. You can also choose ground mounted solar panels that blend with the building’s appearance and don’t damage historic fabric.
Consider Alternatives to Roof Mounting
If roof installation isn’t feasible, such as with thatched roofs, you can still install panels in alternative locations. Options include installing panels on detached outbuildings, garages, or carports, or even in a discreet part of the garden where they won’t impact the building’s appearance. Ground-mounted systems can be designed to blend with the landscape or be screened with planting to reduce visual impact.
It’s important to remember that even these alternative installations will require separate planning permission and Listed Building Consent if installed within the curtilage of a listed building, especially if they are within a conservation area or visible from public spaces. Consulting your local planning authority before proceeding can help ensure compliance.
Consult Conservation Officers
Before planning a solar panel installation on a listed building, it is a good idea to consult local conservation officers or heritage specialists. These professionals have detailed knowledge and can offer guidance on the building’s historical significance, local conservation rules, and best practices for integrating modern technologies without compromising heritage value. They can also advise on suitable locations, panel designs, and materials that minimise visual and structural impact.
Working with conservation officers early in the process can help identify potential issues before work begins.
Work with an Experienced Installer
When installing solar panels on a listed or historic building, working with skilled and experienced installers is a great way to ensure that your installation protects delicate materials, avoids damaging historic fabric, and ensures that all work complies with heritage regulations.
A reputable installer will be able to prepare and submit the planning applications for you, ensuring a seamless transition from planning to delivery that complies with the planning offer.
They should also provide tailored recommendations on design, placement, and materials, which can simplify the planning process, reduce the risk of mistakes, and ensure your solar installation is both effective and respectful of your building’s historic character.
How can you improve sustainability in listed buildings?
In addition to solar panels, there are lots of other ways you can lower your energy costs and improve sustainability in listed buildings.
- Upgrade insulation sensitively – Use breathable materials like sheep’s wool or hemp for walls, lofts, and floors to reduce heat loss in naturally draughty buildings.
- Energy-efficient lighting – Install LED or low-energy bulbs in ways that preserve historic fittings.
- Window glazing – Add internal or secondary glazing to improve insulation whilst keeping original windows intact.
- Efficient heating systems – Consider underfloor heating, high-efficiency boilers, or heat pumps compatible with the building’s structure.
- Smart energy controls – Use programmable thermostats and smart meters or sub meters to reduce unnecessary energy use.
- Rainwater harvesting – Collect and reuse rainwater for non-potable uses like garden irrigation or toilets.
- Solar-compatible alternatives – If standard panels aren’t allowed, explore solar slates, discreet PV tiles, or building-integrated solar solutions. You could also consider novel solutions such as thin-film or roof integrated solutions for sites with particular aesthetic or architectural restrictions.
- Regular maintenance – Keep roofing, windows and general building fabric in good condition to prevent energy loss and reduce future repair impacts.
