For homeowners, landlords and businesses contacted by the council about unauthorised building work or use. Compare quotes from professionals who can explain your options and help you respond in time.

Planning enforcement usually starts with a complaint, often from a neighbour, followed by a council visit or letter. It might be about an extension built without permission, work that doesn’t match the approved plans, a breached condition, or a change of use such as a home business or a house in multiple occupation. The council may ask questions informally, serve a planning contravention notice, or issue an enforcement notice requiring work to stop or be undone. Each stage has deadlines, and ignoring a formal notice can become a criminal offence. A good professional reads the paperwork, checks the planning history and the facts, and advises whether to apply retrospectively, seek a lawful development certificate, negotiate changes or appeal.

Questions people ask

What is a planning contravention notice?

It’s a formal request from the council for information about activities on the land, such as what work has been done, when and by whom. It doesn’t mean enforcement action will follow, but it’s often a step before it. Failing to reply by the deadline, or knowingly giving false information, can be an offence, so take advice before answering.

Should I stop work if the council contacts me?

Not necessarily, but think carefully before carrying on. Continuing to build after a complaint can make it more costly to put things right if the council later requires changes. If the council serves a stop notice or temporary stop notice, the activity must stop, because ignoring one is an offence. Take advice on your own situation.

Can I just apply for planning permission retrospectively?

Often, yes. A retrospective application is judged on its planning merits in the same way as one made before the work. It can be a sensible way to resolve a case, especially if the work is acceptable or could be with small changes. If it’s refused, the council will then consider whether to take enforcement action.

What happens if I ignore an enforcement notice?

Once an enforcement notice takes effect, failing to comply within the period it gives is a criminal offence, and the council can prosecute. It may also carry out the work itself and recover its costs, and the notice stays on record against the property, which can affect a future sale. Acting early keeps more options open.

Is old unauthorised work safe from enforcement?

Some breaches can become immune from enforcement after a period of time, but the rules differ between the UK nations, have changed in England in recent years, and deliberate concealment can affect the position. You usually need strong evidence of when the work was finished or the use began, and a lawful development certificate is the formal way to confirm it.
