As energy prices continue to fluctuate, more homeowners are looking to solar panels to reduce their electricity bills and improve their home's sustainability.
One question we are regularly asked at Ulex Energy is:
"Can I install solar panels on a listed building or in a conservation area?"
The good news is yes – in many cases you can. However, the planning process is different from that for a typical property, and choosing the right type of solar installation can make a significant difference to the likelihood of approval.
Can Listed Buildings Have Solar Panels?
Yes. Being a listed building does not automatically prevent you from installing solar panels.
However, because listed buildings are protected due to their architectural or historic significance, installing solar panels will usually require Listed Building Consent. This applies even if the panels are:
Installed on the rear roof slope.
Not visible from the highway.
Flush with the roof.
Not mounted on a wall.
The key consideration is whether the installation would affect the character of the listed building. Local conservation officers will assess each application individually.
What About Properties in Conservation Areas?
The rules are different if your home is not listed but is located within a conservation area.
In many cases, solar panels can be installed under Permitted Development Rights, meaning planning permission is not required, provided that:
The panels do not project more than 200 mm from the roof surface.
They are not installed on a wall facing the highway.
The visual impact is minimised as far as reasonably practicable.
Every property is different, so it is always worth checking with your local planning authority before proceeding.
Which Type of Solar Panels Are Best for Listed Buildings?
There is no single solution that suits every heritage property. The most appropriate system depends on the building itself, roof construction and the views of the local conservation officer.
1. Conventional On-Roof Solar Panels
Traditional roof-mounted panels are installed on rails above the existing roof covering.
Advantages
Most cost-effective option.
Highest efficiency due to improved ventilation.
Easily removable if required.
Disadvantages
Highest visual impact.
May be less acceptable on prominent roof elevations.
These systems are often suitable where the panels are located on rear roof slopes or hidden from public view.
2. In-Roof Solar Systems
An in-roof system replaces part of the roof covering, allowing the panels to sit flush with the surrounding tiles or slates.
Advantages
Lower visual impact.
Cleaner, more integrated appearance.
Often preferred where aesthetics are important.
Disadvantages
Slightly lower operating efficiency due to reduced airflow.
Requires removal of existing roofing materials.
3. Solar Tiles and Solar Slates
Solar tiles replace individual roof tiles and are designed to blend into traditional roofs.
Advantages
Excellent appearance.
Minimal visual impact.
Frequently the preferred option for sensitive heritage locations.
Disadvantages
Higher installation cost.
Lower power output per square metre than conventional solar panels.
Longer installation times.
While solar tiles can be an excellent solution for some listed buildings, they are not always the most cost-effective option.
What Do Conservation Officers Look For?
Although every application is considered individually, conservation officers generally favour installations that:
Are located on secondary or rear roof slopes.
Have minimal visual impact.
Preserve the historic appearance of the building.
Are reversible without causing permanent damage to the historic fabric.
Use discreet cable routes and minimise alterations to original materials.
Early discussions with the local conservation officer can often make the planning process smoother.
Can Ground-Mounted Solar Be an Alternative?
Where installing panels on the roof would have too great an impact on the appearance of a listed building, a ground-mounted solar array within the property's grounds may be a suitable alternative.
This can often preserve the character of the building while still delivering significant energy savings.
Is Solar Worth It for Heritage Properties?
Absolutely. Many owners of listed buildings assume solar is not an option, but modern solar technology and sympathetic design mean that many heritage properties can successfully incorporate renewable energy.
With careful planning, it is often possible to reduce electricity bills, improve energy independence and lower carbon emissions while respecting the historic character of the property.
