Please note that making applications via the Planning Portal will incur an additional cost.
Types of Building Regulations Application
Building Notice
Can only be used for works to domestic properties, but not for buildings containing flats with shared access. Recommended for minor internal works or simple extensions. With a Building Notice, all of the Building Control Charge is paid at time of deposit and attracts VAT
Full Plans application
Must be used for works to non-domestic buildings or buildings containing flats with shared access, but also recommended for new dwellings and larger more complex domestic extensions. With a Full plans application, the charge is usually split – with a plan deposit charge payable at time of deposit – with the site inspection charge being invoiced when works commence on site. VAT is applicable.
Regularisation
This is a retrospective application - for works that have either been either commenced or completed (without the benefit of Building Control approval).
The Regularisation charge is not subject to VAT – but attracts a surcharge of 30%
