Building control fees and charges

Guidance on building regulation charges - with effect from 1 April 2025.

New dwellings, flats and conversions

The charges for building regulations work are intended to cover the cost of the service. Two methods we may use to establish the charge for building work are:

  • individually determined charges or
  • standard charges

Individually determined charges

Charges are individually determined for larger and/or more complex schemes, which include work consisting of the following:

  • erection of more than 4 dwellings
  • erection of more than 4 new flats 
  • conversion of a building into more than 4 flats
  • erection of dwellings where the floor area of each dwelling exceeds 300m2 in area
  • two or more dwellings where there is a repeat of house/flat type designs
  • converting a large existing building into a single dwelling, and the cost of that work is more than £25,000
  • more than two dwellings are formed from a single dwelling
  • building work of more than 3 storeys above ground level
  • any Table A work and including the above schemes, which will be subject to a Regularisation Certificate Application
  • applications subject to a reversion charge (work reverting from an approved inspector to us)

Standard charges

The charges for most domestic extensions and alterations are known as standard charges and are listed in Table B.
