What is a Building Inspector Building Inspector invoice?

A building inspector invoice records fees for inspecting construction works for compliance with Building Regulations. In England and Wales, building regulations enforcement is handled either by the local authority building control department or by private Approved Inspectors (AIs), now referred to as Registered Building Inspectors (RBIs) under the Building Safety Act 2022 reforms. Private building control businesses work for developers, homeowners, and contractors to provide inspections at key stages of construction — foundations, structural frame, drainage, insulation, fire stopping, and final completion. Fees are charged as a one-off project fee covering all stages, or per-inspection. The invoice should clearly identify the scheme or project, the inspection stages covered, and the certification to be issued on completion.

How to invoice as a Building Inspector building inspector

Private building control fees are typically collected as a lump sum at the start of the project, covering all inspection stages. Issue the invoice at the commencement of the scheme and release the completion certificate only after all stages are satisfactorily inspected and the final payment is confirmed. For large residential developments with multiple plots, phase billing by plot or phase is practical. Issue invoices aligned to plot starts or practical completion. Under Building Safety Act 2022 reforms, higher-risk buildings (HRBs — buildings above 18m or 7 storeys) are now regulated by the Building Safety Regulator. Ensure your invoice references the correct regulatory framework for the project type.
