If you are in any doubt about whether you need to apply for planning permission, you should consult the Planning Department of your council. They will usually give you advice, but if you want to obtain a formal ruling you can apply (on payment of a fee) for a "lawful development certificate" by writing to the council with details of the work you want to carry out.


Beware!

If you build something that needs planning permission without obtaining permission first, you may be forced to put things right later, which could prove troublesome and costly. You might even have to remove an unauthorised building, so check all procedures before you commence work.


Your local authority will not be able to help with property law matters, such as land ownership disputes, 'ancient lights' and rights to light, or restrictive covenants. They are for you to sort out, if necessary with help from a surveyor or solicitor. The NACAB (National Association of Citizens Advice Bureaux) website provides basic advice and information on your rights.

If you are looking at running a business from your extension your local council produce a booklet titled 'Business'. It gives advice about working from home and can also help identify if planning permission is likely to be required.


To give you a rough idea whether you need planning permission or not, view our Quick Reference Table. If you are still in doubt after looking at this, please contact your Local Council Planning Department.

If you have decided that you need planning permission use our easy Step By Step Guide of how to apply for permission.
