What happens if I carry out works without planning permission?

While it is not illegal to develop land without planning permission, it is not lawful and, consequently, if you have failed to get consent for your project, then the local planning authority can take action to have the work altered or demolished. In this instance, you can make a retrospective planning application and if this is refused you can appeal the decision. If you lose, it can prove very costly.

There is a legal loophole: if no enforcement action is taken within four years of completion, the development becomes immune from enforcement action (10 years for a change of use). The development then becomes lawful — but this is too great a risk to take.


What is the basic form of a planning application?

Each site has different requirements but generally an application should include five copies of application forms, the signed ownership certificate, a site plan, block plan and elevations of both the existing and proposed sites, a Design and Access Statement and the correct fee.


How long do I have to begin work?

Planning permission is typically granted for three years — meaning you must begin work in that time or face reapplying.
