Fees and costs
The cost depends on the type and value of the work.
From 1 April 2025:
- £839 if the work was done before May 2005 and is valued under £9,300
- £494 if you are applying for a letter of comfort for an expired warrant issued under the former building acts
- if the work is valued over £9,300, a higher fee will apply based on the national building warrant fee scale
We review these fees every year.
