HOMEOWNERS who build without planning permission risk being ordered to demolish their projects.

In some cases, however, applying for retrospective planning permission can offer a solution, though it is not guaranteed to resolve the issue. Simon Rix, director and senior planning permission consultant at Planix.uk, outlined key points for homeowners to consider.

Mr Rix said: "My advice would be not to panic, but not to ignore the situation either.

"First, establish whether permission was actually required and whether the development complies with any relevant permitted development rights or existing consent.

"If permission was required, obtain advice on the planning merits of the development and whether a retrospective application is likely to succeed."

Recent Government figures reveal that councils across Yorkshire and the Humber issued 410 planning enforcement notices between July 2025 and June 2026, an 11 per cent increase on the previous year.

Retrospective planning permission can be sought under Section 73A of the Town and Country Planning Act 1990, which allows applications for development already completed without approval.

Councils assess these applications on their planning merits, considering factors such as impact on neighbours, design, and compliance with local plans.

However, the fact that the work is already complete does not guarantee approval.

If the development is deemed unacceptable, permission can be refused and homeowners may be required to alter or remove the structure.

Investigations into unauthorised work often begin with a neighbour’s complaint, a site visit, or information received by the council.

Depending on the findings, the council may request a retrospective application, issue an enforcement warning notice, or begin formal enforcement action.

Enforcement notices can require homeowners to stop using the development, alter it, or remove it entirely, potentially at significant cost.

Since April 2024, the general time limit for enforcement in England has increased to 10 years for most breaches, replacing the previous four-year rule.

In cases where a council has already taken action, seeking professional advice promptly is essential.

Enforcement notices come with limited appeal periods, and the correct response will depend on the individual circumstances.

Retrospective planning permission is not a way to bypass planning rules and does not guarantee approval.
