What is a lawful development certificate?
If you want formal confirmation that the existing use of a building is lawful for planning purposes, or that your proposed development does not require planning permission, you can apply for a Lawful Development Certificate(LDC). An LDC can be useful in situations where you need assurance that a particular use, operation, or development is lawful under planning legislation.

Applications for a Lawful Development Certificate can be submitted online to your local council using Planning Portal. You must include enough detail and evidence to support your case; if the information is insufficient, your application may be refused.
Common Questions
There is no single legal definition of "habitable room", as its use and meaning are subject to context. Generally, a habitable room is a space in a building that is designed for people to live, sleep, or spend extended periods of time in, but does not include bath or toilet facilities, corridors or utility rooms.
In many cases, you can extend a house without applying for planning permission by using what's known as permitted development rights, provided certain limits and conditions are met. However, if your plans go beyond these restrictions, you will likely need to apply for householder planning permission.
You do not need planning permission to move internal walls.
Removing a load bearing wall will require building control approval as it is altering the structure of the property. You will be required to provide a report from a structural engineer who will provide structural calculations.
Work on internal walls may also affect fire escape routes, ventilation, drainage or electrics. These should be considered during the design process and work should be carried out by a member of the competent person scheme where possible.
Changing from a commercial use (use class E) to residential(use class C3) falls under permitted development rights, meaning an application for planning permission is not required.
To use the permitted development right you must meet the rules and regulations set out in legislation, this includes submitting an application for prior approval to the local planning authority. The full list of conditions is available on the government website, or our online application form will tell you whether you are eligible.
If you are not eligible for the permitted development right, you will have to submit an application for full planning permission.
Planning permission is not required for the installation of a stair lift, however, if you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.
Stairlifts must be installed in line with BS EN 81-40:2020 which focuses on safety requirements for the installation of stairlifts.
