Start with the address
Chelmsford City Council is the planning authority for the city and its parishes. A CM postcode can still fall under Braintree, Maldon, Brentwood, Basildon, Rochford or Uttlesford. GOV.UK: find your local council.

Council list of conservation areas ↗Listed buildings need a separate conversation
Panels are not permitted development on a building in the grounds of a listed building. Check the building’s status and discuss the actual proposal with the council before a survey.
Council listed buildings page ↗Working on a property in a conservation area
The council explains what changes inside a conservation area and how to check your property. Inside a conservation area the national rules add a specific restriction: panels may not be fitted to a wall or roof slope fronting a highway if you are relying on permitted development. A rear or side slope is often the first alternative to model.

The national permitted development limits
Planning Portal sets out the limits for solar equipment on a house in England as amended on 27 August 2026: projection, ridge height, flat-roof height, appearance, removal, and the listed building, scheduled monument and conservation area restrictions. Ask the installer to state in writing how the design meets each one.

Check the history before relying on a general rule
The council's planning advice pages explain how to check planning history, conditions and ways to get formal confirmation. Use them for your own proposal rather than assuming solar always is, or never is, permitted.

Each town and village guide on this site names its planning authority and links the council's own conservation area information where it could be verified. Where a council website could not be checked on 12 September 2026, the guide says so rather than repeating unverified designations.
Council and Planning Portal sources checked 12 September 2026. Use the planning authority for your own address.
