End-to-End Retrospective Planning Support for Homeowners, Developers and Commercial Operators
If development work has already been carried out without the required planning permission, a retrospective planning application may be necessary to regularise the position and reduce enforcement risk.
At Liongate Planning, we provide a fully managed retrospective planning service across London and Cambridge. We assess your current situation, prepare the required planning documents, and manage the submission process with a clear strategy aligned to local policy and authority expectations.
Our approach is professional, practical, and focused on giving you the strongest possible route toward regularisation.

A Planning-Led, Compliance-Focused Approach
Retrospective applications require careful handling, especially where planning policy, design, amenity impact, and enforcement considerations overlap.
Our planning consultancy background allows us to build applications strategically, not just administratively. By addressing key policy points early and presenting a clear planning rationale, we help reduce delays, minimise risk, and improve the quality of submission.
This approach is especially valuable for:
- Completed extensions and alterations
- Roof and rear additions
- Outbuildings and ancillary structures
- Change-of-use and mixed-use situations
- Cases with potential or active enforcement concerns

Frequently Asked Questions (FAQ)
What is a retrospective planning application?
A retrospective planning application is submitted after development has already taken
place without the required planning permission, to seek formal planning approval.
Can I still get permission after works are completed?
In many cases, yes. Approval depends on planning merits, policy compliance, design,
and local context. A well-prepared application is essential.
Will a retrospective application stop enforcement action?
Submitting an application can be an important step, but enforcement outcomes vary by
case and authority. We provide strategy-led advice to reduce risk and support compliance.
Do you handle the full process?
Yes. We provide end-to-end support including review, strategy, documents, submission,
and council liaison.
Do you work with both residential and commercial projects?
Yes. We support retrospective applications for homeowners, landlords, developers, and
commercial operators.
Do you offer services in London and Cambridge only?
Our core focus is London and Cambridge, but we can also review and support suitable
projects in other UK locations.
