The service

Evidence for your
proposed work.

A Certificate of Lawfulness can provide formal confirmation that proposed work is lawful and does not require a planning application. It is particularly useful for future sales, remortgaging and avoiding uncertainty before construction begins.

Existing and proposed drawings
Scaled plans and elevations clearly show the property before and after the work.

Application preparation
Where instructed, we prepare and submit the application information to the local planning authority.

Important
The council decides whether the proposal meets the relevant permitted-development rules. Starting before a certificate is granted is at the homeowner’s own risk.

Common questions

Useful things
to know.

Is a certificate compulsory?

Not always, but it gives formal evidence that the proposed work is lawful. It can be valuable when selling or refinancing the property.

Can this be used for a loft conversion?

Yes, where the proposed loft conversion is intended to fall within permitted-development rights. The property and proposal must be assessed against the relevant limits and conditions.

Does this replace Building Regulations approval?

No. Planning and Building Regulations are separate processes. A habitable loft conversion will also require Building Regulations approval.
