Building Control fees were adjusted from 15 January 2018, with the integration of some categories of work, which will simplify the fee determination process. The new structure more accurately reflects the process, and time taken on projects, for both the administrative and technical roles. This is reflected in service improvements with regard to plan checking and site inspections.
