Frequently asked questions
Can I install solar on a listed Greenwich townhouse?
Only with Listed Building Consent from the Royal Borough of Greenwich, which is rarely granted on the front and conditional on rear elevations. Expect 10–12 weeks for a decision. Black-frame, all-black panels are usually a planning condition.
