Certification of the completed building is done shortly after completion ideally. There are two types of Certificates :

Opinion of Compliance with Planning Permission 

This is usually done by the designer of the Planning Permission and confirms that the project is in substantial compliance with Planning Permission and any Planning Conditions , contributions etc. It confirms that all the statutory statutory requirements have been met and that the physical form of the building matches that of the Planning Permission.

Opinion of Compliance with Building Regulations 

The designer(s) of the works for construction will certify the completed works as being in compliance with the Building Regulations. In the construction design phase the designers will design the works , structure, building envelope and services to meet the building  regulations.

In the course of the construction works they will carry out inspections to ensure that the works as designed are being built in accordance with their specifications.

On the basis of these inspections and other confirmations / certs from the other designers/ installers  ( See under) they will satisfy themselves that the materials and workmanship on the job meet the requirements of the building regulations.

From the Client’s perspective this means that the necessary professional oversight is carried out from design to completion and that the joint insurance responsibility for the completed works rests with the Contractor and the Professional (as Certifier).

In certain instances where a Design / Build contract is used – ( The contractor designs and constructs the works for construction  ) , the contractor’s engineer or architect ( with their own Professional Indemnity Insurance will design and inspect the ongoing works and certify on completion.

Professional Institutes recommend against professionals certifying completed (covered in) works that they have not designed and inspected during construction phase and Professional Indemnity Insurers can exclude this service for the same reasons.
