Listed Building Consent: Complete Guide
Listed buildings have the strictest planning controls of any property type. Every external AND internal change that affects the building's character needs Listed Building Consent — a separate process from planning permission. This guide explains the rules.
What needs Listed Building Consent
What needs Listed Building Consent
Any works that affect the character of a listed building, inside or out. This includes: extensions, internal wall removal, window replacement, re-roofing, re-pointing, kitchen installation, bathroom installation, new electrics or plumbing routes, and even some decoration changes. The threshold is very low — if in doubt, assume you need consent.
The application process
Listed Building Consent is a separate application from planning permission (though they are often submitted together). There is no fee for Listed Building Consent. The council consults Historic England (for Grade I and II* buildings) and the local conservation officer. Decision targets: 8 weeks (same as planning).
Extending a listed building
Extensions to listed buildings need both planning permission AND Listed Building Consent. The extension must be clearly subordinate to the original building, use appropriate materials, and not harm the building's special interest. Contemporary design (clearly 'of its time') is often more acceptable than pastiche.
