If you own or are thinking of buying a listed building, you’ll need to be aware of Listed Building Consent (LBC)—a legal requirement in the UK for any alterations that may affect the building’s character.
Whether it’s a grand manor or a quaint cottage, listed status means there are strict controls to preserve its historic significance.
What Is a Listed Building?
A listed building is one that has been recognized for its architectural or historic importance and is protected by law. These buildings are graded as:
Grade I – Buildings of exceptional national importance (only 2.5% of all listed buildings).
Grade II* – Particularly important buildings of more than special interest (about 5.5% of listed buildings).
Grade II – Buildings of special interest, making up around 92% of all listed properties.
If your property is listed, you cannot alter, extend, or demolish it without Listed Building Consent from your local planning authority.
When Do You Need Listed Building Consent?
Consent is required for any changes that might impact the character of the building, including:
✔ Internal changes—removing or altering walls, fireplaces, or staircases
✔ External alterations—changing doors, windows, or roofing materials
✔ Extensions—adding conservatories, porches, or outbuildings
✔ Repairs—replacing like-for-like materials still requires approval in some cases
✔ Modern upgrades—installing double glazing, solar panels, or insulation
It’s a common misconception that only exterior changes require consent—internal works can be just as restricted.
The Application Process
Applying for Listed Building Consent is separate from standard planning permission, though both may be required.
The process includes:
1️⃣ Pre-Application Advice – Engage with your local conservation officer early to understand what’s likely to be approved.
2️⃣ Submitting Your Application – Include detailed plans, heritage statements, and justification for the work.
3️⃣ Consultation & Decision – The local authority will assess the application, sometimes consulting Historic England or conservation experts.
Expect the process to take 12–20 weeks, or longer for complex cases.
What Happens If You Don’t Get Consent?
Carrying out unauthorised work on a listed building is a criminal offence—not just a civil matter. The local council can enforce reinstatement at your expense, and in serious cases, owners have faced heavy fines or prosecution.
