When do you need planning permission to demolish?

People often assume demolition automatically needs planning permission, or that it never does. The reality sits in between: much demolition is permitted development with conditions, but several situations push it into needing full consent. This page sets out the distinction.

Permitted development and prior approval

For much demolition in England, the work is permitted development under the General Permitted Development Order. That means you do not need to make a full planning application. However, permitted development for demolition is generally subject to prior approval: you must apply to the local planning authority for approval of the method of demolition and the restoration of the site once the building is down.

Prior approval is a lighter-touch process than full permission, but it is not optional where it applies. The council considers the demolition method and site restoration rather than the principle of demolishing. You should not start until you have either received prior approval or the council has confirmed it is not required, and you must still comply with the Building Act notice requirements that apply separately.

When full planning permission is required

Full planning permission for demolition is needed in a number of situations. Common triggers include:

• Removed permitted development rights: a council can issue an Article 4 direction that removes permitted development rights in a defined area, so demolition there needs a full application.
• Certain building types: the rules treat some buildings differently, and not all demolition is covered by permitted development.
• Demolition as part of redevelopment: where demolition is tied to a wider scheme, the planning application for the new development will usually deal with the demolition.
• Protected buildings and areas: conservation areas and listed buildings have their own consent regimes (covered below).

If you are unsure which category your project falls into, a quick enquiry to the local planning authority will confirm whether prior approval or a full application is needed before you commit.

Conservation areas and listed buildings

The strictest rules apply to demolition in protected settings:

• Conservation areas: demolishing a building in a conservation area is controlled, and you generally need permission before removing it. The aim is to protect the character and appearance of the area, so substantial demolition is scrutinised carefully.
• Listed buildings: demolishing a listed building, or any part of it, normally requires listed building consent. Carrying out unauthorised works to a listed building is a criminal offence, so this is not something to approach as a formality.

In both cases, allow significantly more time and expect to provide more detail about what you propose. Where a building is both in a conservation area and listed, the listed building controls are the more onerous. Always confirm the building's status with the local authority and Historic England's listing records before planning any demolition.

Planning is separate from the Section 80 notice

Whichever planning route applies, it does not replace the Section 80 demolition notice under the Building Act 1984. These are two different controls that often both apply:

• Planning (or prior approval): deals with whether demolition is acceptable in principle and, for prior approval, the method and site restoration.
• Section 80 notice: deals with the safe carrying out of the demolition, served on the local authority before work starts, with the council able to set conditions through a Section 81 counter-notice.

So even where demolition is permitted development and you have prior approval, you generally still need to serve the Section 80 notice. Confusing the two is a frequent cause of projects starting before all the requirements are met. The safest approach is to treat planning and Building Control as separate boxes that both have to be ticked, and to confirm with the council which apply to your specific building.

How to confirm what your project needs

Because the planning position depends so heavily on the building and its location, the most reliable step is to check directly rather than rely on assumptions. A practical approach is:

• Check protected status first: confirm whether the building is listed (via the National Heritage List) and whether it sits in a conservation area or an area covered by an Article 4 direction. These factors have the biggest effect on what is needed.
• Ask the local planning authority: a pre-application or informal enquiry can confirm whether the demolition is permitted development needing prior approval, or whether a full application is required.
• Consider the wider project: if the demolition is part of a redevelopment, the planning application for the new building will usually deal with the demolition, so the two should be planned together.
• Allow time: prior approval, full applications and listed building or conservation area consents each have their own timescales, and protected buildings take longest.

Getting clarity at the start prevents wasted effort and the risk of carrying out demolition that later turns out to have needed permission. For protected buildings in particular, the consequences of getting it wrong are serious, so professional advice is often worthwhile before committing to a method or a date.

Demolition as part of a redevelopment

A great deal of demolition is not done for its own sake but to clear a site for something new. Where that is the case, the planning picture often looks different from a stand-alone demolition:

• The new development drives the application: the planning application for the replacement building usually deals with the demolition of what is there, so a separate demolition consent may not be the right route.
• Plan the two together: treating the demolition and the rebuild as a single project from the start avoids gaps, such as demolishing before the replacement has permission.
• Protected buildings change the calculus: if the building to be cleared is listed or in a conservation area, its demolition is judged not just on the new scheme but on the loss of the existing building, which can be decisive.
• Sequencing matters: it is generally unwise to demolish until you are confident the redevelopment can proceed, since a cleared site without permission to rebuild has its own problems.

For straightforward redevelopments on unprotected sites this is usually manageable, but it underlines why the planning route should be confirmed before any building comes down. Demolishing first and sorting out permission later is the wrong way round, and it can leave an owner with a cleared site and no agreed scheme. As with all demolition, the dependable approach is to establish the building's status and the correct planning route with the local authority at the outset, and to keep the demolition and any new development aligned throughout.
