Inspection schedule
It is the homeowners responsibility to ensure Building Control is asked to inspect works at the relevant stages for the building project.
Failure to request an inspection at the relevant stage, may result in our request to expose elements of the building works at the homeowners cost. If a completion inspection is not requested we will be unable to sign-off the works and therefore not issue a completion certificate.

General note
The inspecting surveyor will advise when additional inspections are required. Inspections are carried out to ensure compliance with the minimum standards of the building regulations. Client specifications on other issues are not commented upon provided the minimum standards of the building regulations are met.
For items not listed above please ask the building control surveyor upon commencement of works for a list of needed inspections. For multiple work types in same job different inspections can be done at same time.
Installers certificates and test results, where appropriate, will need to be checked before a completion certificate can be issued (eg boilers, electrical, etc).
Completion certificates and occupation certificates are useful documents and can aid you to achieve a speedier process when you come to sell your property.
