    Fees for other domestic work, like removing an internal wall or chimney breast, are based on the estimated cost of works. There's no fee payable for cavity wall insulation. Works being carried out for a person with a disability may not carry a fee.

    * You cannot use a Building Notice application for building work to an existing dwelling that increases the floor area of dwelling by more than 10m² or creates a new storey with a floor area of more than 3m².

    ** If you are making an application for more than one of these works at the same time, then only one fee will be charged - if the works include the installation or extension of a heating system that is the fee that will be charged, otherwise the fee will be for a replacement combustion appliance.

  • Fees based on estimated cost of work

    All non-domestic work and some domestic work is based on the estimated cost of the works excluding VAT. The fee is then calculated on a sliding scale.
