Do you need planning permission AND listed building consent?

You may need both. Listed building consent covers the alteration to the building. Planning permission covers the development itself. In conservation areas, you may need: planning permission + listed building consent + consideration of conservation area rules. Your local authority can confirm.

How much does listed building consent cost?

Listed building consent applications are free. However, you may need to commission a heritage impact assessment (£200–£500) and professional drawings. A pre-application discussion with the conservation officer may cost £50–£100.

What happens if you install solar without listed building consent?

Installing on a listed building without consent is a criminal offence under the Planning (Listed Buildings and Conservation Areas) Act 1990. You could face prosecution, fines, and be required to remove the panels at your own cost. Always obtain consent before installing.

Solar Panels on Listed Buildings: Rules & Options

Q: Can you put solar panels on a listed building?

Yes, with listed building consent. Approval is not guaranteed but many councils approve discreet, reversible installations — especially on non-principal elevations. Ground-mounted panels in the garden avoid listed building consent entirely.

Can you put solar panels on a listed building?

Solar panels on a listed building require listed building consent — this applies to ALL external alterations, including panels on the rear roof. Permitted development rights do not override the listed building requirement. Many councils approve applications for discreet, reversible installations — especially in-roof panels or rear-mounted panels. Ground-mounted panels in the garden may avoid the need for listed building consent entirely.

Listed building consent is a separate application from planning permission. Even if your panels would be permitted development on a non-listed building, you STILL need listed building consent.

Process: 1. Pre-application discussion (recommended): Contact your local conservation officer informally to discuss the proposal. Free or £50–£100. This gives you a sense of likelihood before committing.

2. Listed building consent application: Submit to your local planning authority with: - Photographs of the building and proposed panel location - Technical drawings showing panel size, position, and fixings - Heritage impact assessment (explaining how the installation respects the building's character) - Details of mounting system (reversibility is important) - Panel appearance (all-black, in-roof, etc.)

3. Consultation: Historic England may be consulted for Grade I and II* listed buildings. The local conservation officer assesses Grade II applications.

4. Decision (typically 8 weeks): The officer assesses whether the proposal harms the building's special interest.

Cost: Listed building consent applications are FREE (unlike planning applications which cost £258).

Standard solar installation — listed buildings need a more discreet approach — Standard installations suit most homes — listed buildings may need a more considered approach.

What Gets Approved?

Approval depends on the building's grade, significance, and the visibility of the panels:

Most likely to be approved: - In-roof panels on a non-principal (rear/side) elevation - All-black panels on a hidden roof slope - Ground-mounted panels not visible from the principal elevations - Solar tiles replacing existing tiles on a non-principal slope - Installations that are fully reversible (no permanent damage to historic fabric)

Less likely to be approved: - Standard silver-framed panels on the front elevation - Large arrays covering most of the roof - Installations that damage historic fabric (drilling into original timbers or stonework) - Any modification to Grade I or II* buildings without compelling justification

Historic England's position: Solar panels can be acceptable on listed buildings provided they: - Respect the significance of the building - Are positioned on the least sensitive elevation - Are reversible (can be removed without permanent damage) - Are designed to complement the building's character

Discreet solar installation — the approach needed for listed buildings — Discreet, reversible installations on non-principal elevations have the best chance of approval.

Alternatives for Listed Buildings

If standard roof-mounted panels are refused or inappropriate:

Ground-mounted panels — installed in the garden, no alteration to the listed building. May still need planning permission if in a conservation area, but does NOT need listed building consent.
Solar tiles — replace existing tiles with PV-generating tiles (e.g., Marley SolarTile). Virtually invisible. More expensive but more likely to receive consent.
Solar panels on outbuildings — a detached garage, workshop, or stable block may not be listed separately. Check with your conservation officer.
Solar carport — a new structure in the garden with solar panels on the roof. Needs planning permission but not listed building consent.
Energy efficiency improvements instead — if solar is refused, invest in insulation, draught-proofing, and secondary glazing instead (these also need consent on a listed building but are usually approved more readily).

Solar alternatives for listed buildings still deliver good returns — Ground-mounted and outbuilding solar can achieve similar returns without altering the listed building.

Listed Building Grades Explained

Not all listed buildings face the same restrictions:

Grade I (2.5% of listed buildings): - The most historically significant buildings - Extremely strict restrictions — solar consent is rare but not impossible - Historic England is always consulted

Grade II* (5.8% of listed buildings): - Particularly important buildings - Strict but slightly more flexible than Grade I - Historic England is usually consulted

Grade II (91.7% of listed buildings): - The vast majority of listed buildings - Important but with more flexibility for sympathetic alterations - Local conservation officer decides — Historic England consulted only in special cases - Solar consent is regularly granted for discreet, reversible installations

If your building is Grade II (which is most likely), solar approval is achievable with the right approach.
