An enforcement notice is one of the most serious documents a farmer in England can receive. It is issued by the local planning authority where it believes a breach of planning control has occurred — whether that is an unauthorised building, a change of use, or operational development carried out without permission. The notice sets out what the breach is, what steps must be taken to remedy it, and the deadline by which those steps must be completed. Getting this wrong is expensive. Getting it right, quickly, is entirely possible if you know what to do.

What Is an Enforcement Notice?

An enforcement notice is a formal legal document issued under Section 172 of the Town and Country Planning Act 1990. It identifies an alleged breach of planning control, requires the person responsible to take specified steps to remedy that breach, and sets a compliance period — typically 28 days to several months, depending on the nature of the breach. Crucially, an enforcement notice does not take effect immediately. There is a 28-day appeal window from the date the notice is served, and this window is one of the most important tools available to you. Missing it has serious consequences. Acting within it gives you options.

The 4-Step Enforcement Notice Checklist

If you have received an enforcement notice on your farm, work through the following four steps immediately. Time is critical. The 28-day appeal window runs from the date the notice is served, not the date you read it.

Step 1: Check the Notice Is Valid and Note the Appeal Deadline

Read the notice in full. Check the date of service on the notice — this is the date from which the 28-day appeal period runs.
Confirm the notice has been correctly served on the right person. Enforcement notices must be served on the owner of the land, the occupier, and any other person with an interest in the land. A notice served on the wrong person, or not properly served, may be invalid.
Check whether the alleged breach is accurately described. The notice must specify the matters alleged to constitute the breach. If the description is factually wrong, vague, or excessive in scope, this can form a ground of appeal.
Note the compliance period stated in the notice. This is separate from the appeal window and sets out how long you have to carry out the required steps if you do not appeal or if your appeal fails.
Write down the appeal deadline — 28 days from service — and treat it as a hard deadline for all decisions.

Step 2: Take Legal and Planning Advice Immediately

Contact a planning consultant or solicitor with agricultural and enforcement experience as soon as possible — ideally within the first few days of receiving the notice. The appeal grounds are technical and specific, and the wrong approach can close off options.
There are six statutory grounds of appeal against an enforcement notice (under Section 174 of the TCPA 1990). These include: that planning permission ought to be granted; that the breach has not in fact occurred; that the matters alleged do not constitute a breach; that the breach is immune from enforcement due to the passage of time; and that the steps required are excessive. Understanding which grounds apply to your situation requires professional assessment.
Ask your adviser to assess whether a lawful development certificate (LDC) may be available. Where a use or operation has been in place for the relevant immunity period (four years for operational development and most changes of use; ten years for change of use to a dwelling), an LDC provides a defence against enforcement.
Check your farm's planning history. Previous planning permissions, prior approval decisions, and lawful development certificates may all be relevant to whether the alleged breach is correct.

Step 3: Gather Evidence to Support Your Position

Compile any evidence that demonstrates when the development or use began. This is particularly important if you are relying on the four-year or ten-year immunity rules. Relevant evidence includes: historic aerial photographs, dated invoices and receipts, contractor records, tenancy agreements, farm business accounts, correspondence, insurance documents, and planning application records.
Take your own dated photographs of the land and any structures now, and preserve any existing records in a safe place. The council will be gathering its own evidence — you should do the same.
If the notice relates to a building, gather any documents relating to its construction: invoices, building contracts, planning correspondence, and any communications with the council. These can support both the timeline of the development and its intended use.
Review any permitted development rights that may apply. If the development was lawfully carried out under agricultural permitted development, that is a complete answer to the enforcement notice. Your planning consultant can assess whether this argument is available on the facts.

Step 4: Decide Whether to Appeal, Comply, or Negotiate

You have three realistic options: appeal the notice, comply with the notice within the compliance period, or seek to negotiate a revised requirement with the local planning authority. Doing nothing is not an option — non-compliance with an enforcement notice is a criminal offence and can result in unlimited fines.
If you appeal, the notice is suspended while the appeal is pending. This means you do not have to comply during the appeal process. Appeals are determined by the Planning Inspectorate and can take several months to over a year. A well-founded appeal can result in the notice being varied or quashed entirely, or planning permission being granted on appeal.
If the breach is genuine and the notice is correctly framed, it may be more cost-effective to negotiate with the council over the compliance steps or timescale, or to submit a retrospective planning application. Some councils will agree to a compliance timetable that is more workable for the farm business.
If you intend to appeal, your planning adviser should submit the appeal to the Planning Inspectorate via the Appeals Casework Portal before the 28-day deadline. An appeal submitted one day late is invalid.

Practical Implications for Your Farm Business

An enforcement notice affects not just the development in question but your ability to sell, mortgage, or diversify the holding. It will appear in any local land charges search, and it remains registered against the land even after compliance. If you are in the process of buying or selling a farm and an enforcement notice is discovered, understanding its scope and compliance status is critical to completing the transaction. More broadly, a proactive approach to planning compliance — auditing your holding's planning status before problems arise — is far less costly than dealing with enforcement after the fact. A farm planning audit identifies both the risks and the opportunities on your holding, including permitted development rights you are not currently using.
