Can I install solar in Chesham conservation area?

Yes for many homes, and roof slopes are not the restriction. On an unlisted house in the Chesham Conservation Area, pitched-roof panels are permitted development if they project no more than 0.2 m from the slope and sit no higher than the highest part of the roof, excluding chimneys. Panels on a wall, balcony or roof enclosure fronting a highway are not permitted development, a flat-roof array needs a prior approval application first, and listed houses fall outside these rights. The Article 4 entries naming Chesham on the government's planning data site cover agricultural buildings, mineral working, caravan sites, means of enclosure and poultry production, but ask Buckinghamshire Council to confirm for your street.
