Certificate of Lawfulness Application

If you want to be certain that an existing conservatory is lawful for planning purposes or that your proposed conservatory does not require planning permission, we can apply for a certificate of lawfulness on your behalf.

The Government has introduced a process called a Certificate of Lawfulness application. This procedure follows a similar route to a full planning application, although in the case of proposed works the application is not advertised and there is no consultation with neighbouring properties. In the case where the development has already taken place, this is advertised and consultation with neighbouring properties is carried out.

The process normally takes around 3 - 4 weeks to complete, around half the time of a full planning application.

The main benefit of ensuring that you have either a Certificate of Lawfulness or full Planning Permission should that be required, is when ownership of the property is transferred to another party there are no unnecessary delays in respect of planning matters, which appear to be the case at the present time.

Retrospective Planning Permission

We can also provide you with plans for a Retrospective Planning application where a conservatory has been built and Planning Permission should have been granted. As with any application, approval cannot be guaranteed. This type of application is often required during a house conveyance.


As stated above, around 35% of conservatories will require Planning Permission. A conservatory is treated in exactly the same way as a normal domestic extension in terms of Planning Permission.

Regretfully the myth that most conservatories are exempt from Planning Permission is often made worse by some conservatory suppliers/cowboys, that simply side step the issue or place the Planning Permission back onto the client with the use of small print in a contract.

Breaches of Planning Permission for conservatories are often found years after the conservatory has been built, when a homeowner is trying to sell a property. The buyers Surveyor will complete a survey on the property and it is their job to find any breaches of Planning Permission, this is made even more obvious today with the fact that all Planning Applications are now on-line and it is very easy to check if a conservatory has Planning Permission Approval.

WARNING - If it transpires after the conservatory has been built, that Planning Permission was required, then it is the HOME OWNER THAT IS RESPONSIBLE for rectifying the breach of Planning Control, not the installer of the conservatory.

If you have to remove or re-size your conservatory - even years after its been built, then this can prove to be an expensive task.

We would advise that if you are unsure if you require planning permission for your conservatory, that you contact your Local Authority and speak to a Planning Officer.
