What happens if you ignore an enforcement notice

 

People do ignore them. Sometimes out of hope, sometimes because the letter went to an old address, and sometimes because nothing happens for months and it starts to feel like nothing ever will.

It does not work. Once the time for compliance has run out, an enforcement notice stops being a piece of paper asking you to do something and becomes four separate problems at once. You have committed a criminal offence. The council can come onto your land, do the work itself and send you the bill. It can ask a court for an injunction. And if you made money out of the breach, a court can take that money as well as fining you.

None of those go away because you moved house, and none of them go away because time passes.

This page covers England. Wales works the same way on most of it, and we say so where it differs. It sits inside our wider guide to planning enforcement.

When you are treated as having ignored it

 

Every enforcement notice gives you a period to comply. That period starts when the notice takes effect, not when it lands on your doormat, and a valid appeal puts the whole thing on hold until the appeal is decided.

Once the compliance period has ended, the law keeps asking the same question: have the required steps been taken, and have activities the notice required to stop actually stopped? If not, the person who is the owner at that time is in breach of the notice.

That matters because liability is not frozen on the deadline day. A later buyer can become the person in breach while the notice remains uncomplied with, even if somebody else carried out the original development and the original deadline passed before the purchase.

 

It is a criminal offence, and the fine has no ceiling

 

Being in breach of an enforcement notice is a criminal offence. Not a civil debt, not a planning matter, a criminal offence that ends in a conviction and a criminal record.

There is no maximum fine. The case can be heard in the magistrates’ court or the Crown Court, and in either the fine is unlimited. You will still see the figure of twenty thousand pounds quoted on council websites and in old model notices. That cap was removed in March 2015 and it has not applied for over a decade.

There is also a specific instruction to the court about how to set the fine. It must have particular regard to any financial benefit that has come to you, or looks likely to come to you, because of the offence. So if you let out an unauthorised flat for three years, the rent you collected is not background information. It is the starting point for the fine.

 

You can be prosecuted more than once

 

This is the part almost nobody expects, and it is the reason ignoring a notice gets worse rather than staying still.

The offence can be charged by reference to any day, or any longer period of time. Once you have been convicted, you can be convicted again for a further period after that conviction. Keep the breach going and you can be taken back to court for it again, and then again.

Paying a fine does not buy you the right to carry on. It buys you nothing except a conviction and a smaller bank balance, and the notice is still there the next morning.

 

Tenants and occupiers are not safe either

 

If you are not the owner but you have control of the land or an interest in it, you have your own duty. You must not carry on an activity the notice requires to stop, and you must not cause or allow anyone else to carry it on.

Break that and you commit a separate offence, on the same unlimited fine, and it can be charged repeatedly in the same way.

So a landlord who does nothing and a tenant who keeps trading can both end up in court over the same notice.

There is now a specific possession route where the tenancy itself prevents compliance. Following the Renters’ Rights Act 2025, Ground 6B(g) allows a landlord to seek possession where that is necessary to comply with a planning enforcement notice or an injunction. The government added this point to its planning enforcement guidance in May 2026. That does not make possession automatic, but it matters where the owner genuinely cannot comply while the tenant remains in occupation.

 

The two defences, and how narrow they are

 

There are only two, and neither is a way out for someone who simply did not bother.

• the first is for an owner who shows they did everything they could be expected to do to secure compliance; it is aimed at the owner who genuinely cannot make it happen alone, for example because a tenant is refusing to move, and not at the owner who could have done the work and did not
• the second is for a person who was never served with a copy of the notice, where the notice is also not on the council’s enforcement register, and who shows they did not know it existed

The second one has two limbs and you need both. If the notice is on the register, that defence is gone even if nothing was ever posted to you. That is why the enforcement register matters so much to anyone buying land, and it is the first thing a defence solicitor will check.

 

The council can do the work and bill you

 

Prosecution punishes you. It does not put the building back. So there is a second, entirely separate power, and councils often use it alongside a prosecution rather than instead of one.

If the steps required by the notice have not been taken in time, the council may enter the land, take those steps itself, and recover from whoever then owns the land any expenses it reasonably incurred in doing so. That is usually called direct action.

It is expensive. You are paying a contractor the council chose, at the price the council agreed, on a job nobody was competing for. There is no cap and no fixed scale. Our page on direct action sets out who ends up with the bill, and how to try to pass the cost on to whoever caused the breach.

Two further points matter and are easy to miss:

• obstructing someone exercising that power is itself an offence, carrying a fine of up to level 3 on the standard scale, currently £1,000
• the Act allows regulations to secure those costs against the land itself, so if you are facing a bill of this kind, take advice on whether it has been secured against your property before you assume that selling up clears it

 

If someone else caused the breach, the bill can follow them

 

There is a genuinely useful rule here for anyone who inherited somebody else’s mess.

Where a copy of an enforcement notice has been served, any money the owner or occupier spends complying with it, and any sum the owner pays the council for direct action, is treated by law as having been spent for the use and at the request of the person who committed the breach of planning control.

In plain terms, the law treats that person as though they had asked you to spend it. If you bought a property and the previous owner built the thing being enforced against, that is your route to trying to get the money back from them. It is a civil claim and you will need a solicitor, but the statutory footing is there.

 

An injunction, which is the serious one

 

Where a council thinks it necessary or expedient to have a breach stopped by injunction, it can apply to the High Court or the county court for one. It can do that whether or not it has used any of its other enforcement powers, and it does not have to prosecute first. Our page on a planning injunction covers the power in full, including the fact that it can be used before a breach has even started.

The court grants whatever injunction it thinks appropriate to restrain the breach. It can also be issued against a person whose identity is unknown, which is how councils deal with unauthorised works where nobody will give a name.

Breaking an injunction is contempt of court, and that is a different order of trouble from a planning fine. The court has powers to punish contempt that include sending someone to prison. If a council has gone to court for an injunction, get a solicitor that week.

 

They can take the profit as well

 

This is the one that turns a bad situation into a ruinous one, and it applies where a breach has made real money.

Because failing to comply is a criminal offence, the proceeds of crime rules can be used. If the case reaches the Crown Court, and either the prosecutor asks or the court decides it is appropriate, the court has to work out whether the defendant benefited from the offence and, if so, make a confiscation order for that benefit.

Three things about it are worth understanding:

• a confiscation order is separate from the fine; you can be ordered to pay both
• only the Crown Court can make one, so a case that starts in the magistrates’ court has to move up
• the questions are decided on the balance of probabilities, which is the civil standard, not the much higher standard needed to convict

The sums are not small. If the offence was renting out unauthorised units, the benefit is measured on the income, and that figure can dwarf anything the planning system itself would ever have charged you.

 

Is there a cost?

 

Ignoring a notice is the most expensive option available to you. There is a fine with no upper limit, the council’s costs of doing the work, potentially a confiscation order, and your own legal fees on top.

Putting things right has a cost too, and it is worth knowing what that looks like before you decide. Applying for permission after the event carries a fee, and so does asking for the planning merits to be considered as part of an enforcement appeal. Our planning fees page sets out where those charges sit and how they are worked out. Complying with the notice will have its own building cost, which is usually the biggest single number.

 

What if you think the notice is wrong?

 

Then you appeal it, and you do that before it takes effect. That is the moment the whole thing turns on.

A valid appeal suspends the notice while it is decided, and it is your one chance to argue that the breach never happened, that it is too late to enforce, that the requirements go further than they need to, or that permission should be granted for what you did. Our page on the enforcement appeal grounds works through each of those, and the deadline and procedure are on our page about enforcement notices and how to appeal. Our general guide to planning appeals explains how appeals to the Planning Inspectorate run.

Miss that deadline and the notice is valid whether it was fair or not. In a later prosecution you cannot defend yourself by arguing about the planning merits, because that argument had its own forum and you did not use it.

That does not mean negotiation becomes impossible. Section 173A lets the council withdraw its notice, waive or relax a requirement, or extend the compliance period even after the notice has taken effect. It is discretionary and the request does not stop prosecution or direct action by itself, so it is a route to resolving an extant notice, not a substitute late appeal.

 

So should you ever just leave it?

 

No. There is no version of this where waiting improves your position.

What people are usually hoping for is that the council is bluffing, or too stretched to follow through. Some councils are stretched. But an enforcement notice does not expire, it binds whoever owns the land next, and it sits on a public register where every future buyer’s solicitor will find it. A breach you have got away with for five years is still a breach on the day someone finally decides to act.

If you genuinely cannot afford to comply, say so, in writing, early, and ask what the council will accept. If you think the development would be acceptable, apply for permission and talk to them about holding off while it is decided. Councils have a discretion about whether to prosecute and they do use it, but they use it for people who engage with them.

If the council does move towards prosecuting, it will usually ask you in for an interview under caution before it decides. Prepare for that one properly, because it is the point at which what you say is hardest to take back.

The one thing that never helps is silence.

Ignoring an enforcement notice: relevant legislation

The offence is in section 179, direct action and cost recovery in section 178, and injunctions in section 187B, all of the Town and Country Planning Act 1990. Confiscation sits in a different Act entirely. Check the “Changes to Legislation” panel at the top of each page below before relying on the wording.

Section 179(9) of the Town and Country Planning Act 1990 reads:

In determining the amount of any fine to be imposed on a person convicted of an offence under this section, the court shall in particular have regard to any financial benefit which has accrued or appears likely to accrue to him in consequence of the offence.

• Town and Country Planning Act 1990, s179: the offence, the two defences, repeat prosecution and the unlimited fine
• Town and Country Planning Act 1990, s178: the council’s power to do the work and recover its costs
• Town and Country Planning Act 1990, s187B: injunctions, including against a person whose identity is unknown
• Town and Country Planning Act 1990, s188: the enforcement register, which the second defence depends on
• Proceeds of Crime Act 2002, s6: when the Crown Court must consider making a confiscation order
• SI 2015/664, Sch 4 para 18: the 2015 change that removed the old cap and made the fine unlimited
