Indicate if you have consulted a Structural Engineer and attach any structural calculations. These calculations may be sent to our Structural Engineer for appraisal. Please be aware, if the drawings and calculations are not clear and concise, it will take more time to process them which may incur additional fees. Find out more about appointing a Structural Engineer.
Works carried out

If a planning application was made in relation to the project, include the reference number.
A building regulation application does not qualify as planning permission. Find out more about when you need planning permission.
Full plans application can be approved subject to conditions which can then be cleared at a later date and/or on site. Select yes or no to agree or disagree with having a conditional approval.
You can allow us either five weeks or with your agreement an extension to two months to carry out the plan check and issue a decision notice. Select yes or no to agree or disagree to a time extension.

The floor area includes all the storeys of an extension or new build. It is calculated by reference to the finished internal faces of the walls enclosing an area. If at any point there is no enclosing wall, it should be calculated by reference to the outermost edge of the floor.
The estimated cost for works should be as they would be charged by a builder even if you are proposing to undertake any or all of the work yourself.
Please tick to confirm that you have read and understood the conditions that you are agreeing to.
