If you carry out unauthorised work or do not follow the details of approved plans, you will be in contravention of the Planning (Listed Building & Conservation Areas) Act 1990 . This may result in enforcement proceedings or you may be required to submit a retrospective application.
You will be required to make good any damage or to reinstate any works which are not approved at your own expense. You may also be liable to prosecution as carrying out unauthorised works to a Listed Building is a criminal offence.
Examples of unauthorised works where reinstatement has been required include:
- Installation of new windows, particularly uPVC or stained finished windows which are rarely appropriate in Listed Buildings.
- Poor re-pointing of brickwork.
- External re-painting.
- Installation of roof windows.
Internal alterations (eg: new openings)
- Removal of internal doors.
- Alterations to staircases.
Reinstatement is expensive and inconvenient. You are strongly advised to seek the advice of the Planning Services section before carrying out any works to the building.
When a property is sold, a solicitors’ search/ Homebuyers Pack will highlight all Listed Building Applications made. Failure to follow correct procedures can delay or jeopardise the sale of the property.
