What is a listed building?

A 'listed building' is a building, object or structure in the UK that has been considered as of national importance in terms of architectural or historic interest and included on a register called the List of Buildings of Special Architectural or Historic Interest.

Buildings are listed to help protect the physical evidence of our past, including buildings, which are valued and protected as a central part of our cultural heritage and our sense of identity. Historic buildings also add to the quality of our lives, being an important aspect of the character and appearance of our towns, villages, and countryside.

There are three listing grades:

- Grade I - Buildings of exceptional interest

- Grade II* - Particularly important and more than special interest

- Grade II - Buildings of special interest, warranting every effort being made to preserve them (this is the most common)

If you live in a listed building it means you cannot demolish or alter the building in a way that changes its character without Listed Building Consent.

Common Questions

Do I need planning permission or building control approval to replace soffit boards?

Maintenance of fascias and soffit boards such as replacement or painting generally does not require planning permission.

However, if you live in a listed building or designated area (conservation area, national park, area of outstanding natural beauty) you should check with your local planning authority before carrying out any work.

Building regulation approval is not normally required for this work, but you should ensure that the ventilation for the building is not impacted.

How long does planning permission last?

By law, any planning permission granted expires after a certain period. Generally, unless your permission says otherwise, you have three years from the date it's granted to begin the development. If you haven't started work by then, you will probably need to reapply.

What is the 10-year rule for planning enforcement?

The failure to obtain planning permission or comply with the details of a permission is commonly known as a 'planning breach'.

A planning breach usually occurs when:

  • A development that requires planning permission is undertaken without the permission being granted - either because the planning application was refused or was never applied for
  • A development that has been given permission subject to conditions breaks one or more of those conditions.

If the breach involves a previously rejected development (or the retrospective application fails) the council can issue an enforcement notice requiring you to put things back as they were.

There are statutory time limits for enforcement, these vary based on when the breach took place.

If the breach took place prior to 25 April 2024
  • Change of use of a building, or part of a building, to use as a single dwelling house - Enforcement action can no longer be taken once the unauthorised use has continued for four years without any enforcement action being taken
  • Operational development relating to building, engineering or mining - Enforcement action can no longer be taken from four years, beginning the date where the operations were substantially completed.
If the breach took place on or after 25 April 2024
  • Change of use of a building, or part of a building, to use as a single dwelling house - Enforcement action can no longer be taken once the unauthorised use has continued for ten years without any enforcement action being taken
  • Operational development relating to building, engineering or mining - Enforcement action can no longer be taken from ten years, beginning the date where the operations were substantially completed.
Other time limits:

There is no time limit for enforcement on breaches of planning control relating to relevant demolition.

For any other breach of planning control, ten years beginning with the date of the breach. This predominantly applies to changes of use.

Do you need planning permission to install an outside flue?

Fitting, altering or replacing an external flue, chimney, or soil and vent pipe is normally considered to be permitted development, not requiring an application for planning permission, providing certain conditions are met.

Read about the conditions which must be met to comply with permitted development rules.

Building regulations apply to installing a flue, and installation should be carried out by a suitably qualified installer.

Read about building regulations for flue installation.

Is there a maximum height for a new dormer?

Yes, under permitted development, a new dormer must not be higher than the existing highest part of the roof. It should also have materials that are in similar appearance to the existing roof. Additional limits apply in conservation areas and on listed buildings. Read about planning permission for loft conversions on Planning Portal
