Building control fees and charges

A guide to our building regulation charges from 1 April 2023 which includes charges for:

  • new dwellings, flats and conversions
  • domestic extensions and alterations
  • all other work (excluding domestic alterations and extensions and the creation of new dwellings)

The charges for our building regulations work are intended to cover the cost of the service. We establish the charge for building work using either, individually determined charges or standard charges.

Individual charges are normally determined for larger and more complex schemes. Building work that is carried out to benefit a disabled person, is charge exempt.

  • All other Charges which are set out in Tables A, B, C1 C2 now include VAT (at the standard rate of 20%)
  • *Additional Fee - DIY Electrical Work * To reflect the Local Authority’s costs, if relevant electrical work is to be carried out using a Part P registered electrician or an electrician qualified to issue an appropriate electrical certificate for work under BS 7671, then the standard charges are significantly reduced as shown in Tables A and B. However, if anyone other than such a specialist electrical contractor undertakes the electrical work, then an additional charge of £384 including VAT is to be added to the Standard Charges for the Full Plans Submissions Inspection and Building Notice Charges.
  • These charges have been set by the Authority on the basis that the building work does not consist of, or include, innovative or high-risk construction techniques (details available from the Authority) and/or the duration of the building work from commencement to completion does not exceed 18 months.
  • The charges have also been set on the basis that both the designs and the building work are to be undertaken by persons or companies that are competent to carry out the relevant design and building works. If they are not, your application may subsequently incur supplementary charges.
  • Multiple work reductions - Where it is intended to carry out several types of works at the same time (eg a loft conversion and a separate extension or perhaps a garage conversion and a dormer extension etc), then the combined Plan Charge can be reduced. The reduction is calculated by paying the full amount for the most expensive category and then the other work category charge can be reduced by 50%.
