New builds and conversions

The Building Regulations 2000 (as amended). The Building (Local Authority Charges) Regulations 2010

In accordance with The Building (Local Authority Charges) Regulations 2010, charges are made by the Council in connection with their function relating to the Building Regulations.

These charges replace the previous statutory charges made under "The Building (Local Authority Charges) Regulations 1998", and the London Borough of Harrow Charges Scheme No.12 - 2023 and are applicable to any application received on or after 3rd April 2023.

The charges for Building Regulation work are required to cover the cost of the service.

There are two methods of establishing the building regulations charge for building work

  • standard charges
  • individually determined charges 

Standard charges

The charges for new dwellings and conversions to form dwellings and are listed in Tables A.  

These standard 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 12 months.

The charges have also been set on the basis that the design and building work is undertaken by a person or company that is competent to carry out the relevant design and building work referred to in the standard charges tables.  If they are not, the work may incur supplementary charges.

Individually Determined Charges

Charges are individually determined for the larger and/or more complex schemes and developments. This includes:

  • Work consisting of the erection or conversion of more than 10 dwellings, or
  • Work consisting of the erection or conversion of dwellings exceeding 3 storeys (including any basements) and/or where the floor area of a dwelling exceeds 300m2 (excluding any garage or carport)
  • Where buildings other than dwellings are converted to dwellings by a material change of use.

If your building work is defined as requiring an individual assessment of a charge, please email Building Control giving a description and details of the intended work, including plans where applicable; and preferably including build cost and estimated construction time. We aim to respond within one working day.
