Upon approval of your planning application your building regulation drawings and engineers’ calculations will be submitted to building control for an application, this is to ensure all the information we have provided is double checked and compliant by a third party before work commences. This also goes for the builder too, the inspector will ensure the builder has followed our plans and installed them correctly resulting in a certificate, signing off the project. Once the application has been submitted you will receive a name and number of your assigned inspector who your builder can contact to arrange the different site visits, this should be normal practise for the builder.
