You dont need planning permission for some building work. This is called permitted development.
You can find examples of common projects at the Planning Portal. This will tell you if your project is covered by permitted development, which means you won’t need planning permission.

Lawful Development Certificate - Proposed development
If you are still unsure whether planning permission is needed, you can submit an application for a Certificate of lawful development. This is not the same as planning permission, but if a Certificate is issued (because we agree that planning permission is not required) then it is proof that your development is ‘lawful’.
Please note that a fee is payable for a Certificate of lawfulness of proposed development which is half the normal fee. For a ‘householder’ development (such as an extension) , this means a fee of £90. If you wish to apply to confirm that something you have built already does not require planning permission, then a full fee would be payable, which is £190 for a householder development.
