Thinking about works on your listed property?
Before you start, check what’s allowed — and what requires Listed Building Consent.
Owning a listed building is a privilege — but it comes with strict planning rules. This guide explains what listed status means for homeowners, when consent is needed, how councils treat common works, and how to move your project forward without costly mistakes.
What Are Listed Buildings?
A listed building is one officially recognised for its architectural or historic importance. Once listed, the building (and often its curtilage — the land and structures around it) is protected by law. This means you’ll need special consent for alterations, extensions, or sometimes even routine maintenance.
Grades of Listed Buildings Explained
In England and Wales, there are three main grades of listing:
- Grade I – Buildings of exceptional interest (around 2.5% of listings)
- Grade II* – Particularly important buildings (about 5.5%)
- Grade II – Buildings of special interest (over 90%)
The grade affects how strictly works are scrutinised. For most homeowners, Grade II is the relevant category, but restrictions are still significant.
When Do You Need Listed Building Consent?
You’ll need Listed Building Consent (LBC) for any work that could affect the character of the building, including:
- Extensions and structural alterations
- Installing new windows or double glazing
- Adding solar panels or heat pumps
- Internal changes (removing walls, fireplaces, staircases)
- Exterior works like new doors, roof materials, or repointing
Even like-for-like repairs may need consent, depending on the council’s interpretation.
Common Works & Council Quirks
Homeowners often run into issues with “everyday” upgrades:
- Windows: Replacing timber with uPVC is almost always refused.
- Solar panels: Some councils allow discreet roof-mounted panels; others refuse them outright.
- Disabled access: Councils balance access requirements with historic preservation — designs must be sympathetic.
- Energy efficiency (EPC): Listed buildings are usually exempt, but improvements still need consent.
