Validity of planning permission
Could you please advice how long a planning permission is valid for once approved by the local authority council
My area comes under the London Borough of Hounslow
It is generally 3 years from the time of receiving planning permission to the point of completion of the works.
If you are unsure then the best thing to do is to contact your local planning authority and ask them.

Once you have obtained planning permission you have 3 years, from the date of the approval, to start the work. Once you have started the work, which is presuming you have Building Regulations approval in place, and the Local Authority have carried out a commencement inspection, the application will last indefinitely.
