Building regulation fees and charges tables

Building regulation fees and charges - Table B

Standard charges for:

certain small buildings, extensions, and alterations to dwellings.

Where work comprises more than 1 domestic extension the total internal floor areas of all the extensions shown on the application may be added together to determine the relevant charge. Please note however, the area of loft conversions may not be aggregated to an extension, but a 50% discount can be applied. If the extension(s) exceed 100m2 or 3 storeys in height, then Table D applies (subject to a minimum plan charge equal to a minimum build cost of £100,000).
