If you are in the process of buying a property and there are concerns that planning permission may be missing, it is completely understandable to feel unsure about how serious the risk is and what you should do next. Unauthorised works can affect a property’s value, future saleability, and even lead to enforcement action.
This guidance explains how to find out whether planning permission exists and the practical steps that can help reduce risk before you proceed with a purchase.
Understanding the issue or context
Planning issues often come to light during conveyancing searches, surveys, or when alterations are obvious but paperwork is incomplete. Sometimes records are missing due to age, administrative error, or changes in how local authorities stored information.
Buyers are often left asking:
- whether permission was never obtained
- whether records simply cannot be found
- what happens if enforcement action is taken later
The key issue is not just identifying whether permission exists, but understanding how to protect yourself if it does not.
The legal rules or framework
In England and Wales, most structural alterations, extensions, or changes of use require planning permission, unless they fall within permitted development rights.
Local planning authorities keep records of granted permissions, but older approvals may not always appear in standard online searches. The absence of a record does not automatically mean permission was never granted, but it does raise a risk that needs to be managed.
Enforcement action is usually time-limited. In many cases, if unauthorised development has existed for a certain period without action, the local authority may be prevented from taking enforcement steps. However, this depends on the type of development and the facts involved.
Because of this, buyers should not rely on assumptions and should take active steps to clarify the position.
Practical steps to take
If you are concerned that there may be no planning permission at all, the following steps can help bring clarity and reduce risk:
- Contact the local authority directly
Ask the planning department to search archived or older records that may not be visible online. - Request seller documentation
Ask the seller for any historic approvals, plans, or correspondence relating to the works. - Review surveyor comments carefully
Surveyors often flag alterations that appear inconsistent with the property’s age or records. - Consider a lawful development certificate
In some cases, this can formally confirm that enforcement action is no longer possible. - Discuss indemnity insurance
Planning indemnity insurance may offer protection if permission cannot be confirmed, provided no contact has already been made with the council.
These steps allow you to make an informed decision before committing to the purchase.
Common pitfalls to avoid
Buyers can unintentionally increase their risk by:
- Assuming missing records mean no problem
- Proceeding without raising queries through their solicitor
- Contacting the council too late, affecting insurance options
- Ignoring survey warnings
Avoiding these pitfalls helps ensure that risks are identified and managed before exchange of contracts.

This depends on how long the works have existed and the type of development.
What is planning indemnity insurance?
It is insurance that can protect against losses if enforcement action is taken in future.
