A completion certificate from Brent Council Building Control (or an approved inspector) confirms your works comply with Building Regulations. It is essential for selling or re-mortgaging — lenders and conveyancers require it. We manage the inspection sequence and close out sign-off as part of every Complete package.
Extensions and loft conversions in Brent that change the building's energy characteristics require an updated EPC (or SAP/SBEM calculation as part of Part L compliance). We include Part L calculations in every Complete and Bespoke package.
