Clerk of Works: an old role, a current need
Historically the Clerk of Works was the owner's eyes on site — checking workmanship and adherence to drawings. The role has largely disappeared from residential work, leaving most homeowners without an independent technical voice.
Building Control's narrower job
Building Control inspects against the Regulations at defined stages. It is not present continuously, and it is not concerned with workmanship beyond the regulatory threshold.
Filling the gap
Modern services like BuildJourney fill the same gap the Clerk of Works used to fill — a homeowner-facing technical advisor, framed around today's Building Regulations.
