Question: What is an M&E Clerk of Works?
Answer: An M&E Clerk of Works is an experienced building services professional appointed to inspect the mechanical and electrical installation on site on behalf of the client. Their role is to check that the installation is being carried out in accordance with the drawings, specifications, Building Regulations, British Standards and good practice, and to report on quality, progress and any defects.
Unlike the contractor's own supervision, the Clerk of Works is independent and represents the interests of the client, helping to ensure that what is designed is actually delivered.
Question: Why appoint an M&E Clerk of Works?
Answer: Building services are often concealed above ceilings, within risers and behind walls, so defects can be difficult and expensive to identify after completion. An M&E Clerk of Works identifies issues while they can still be corrected, reducing the risk of latent defects, commissioning failures, performance shortfalls and disputes.
Independent inspection is particularly valuable on design-and-build contracts, where the contractor controls both design and installation, and on projects with demanding performance requirements such as BREEAM, Passivhaus or net zero carbon targets.
Question: What does an M&E Clerk of Works inspect?
Answer: Typical inspection activities include:
- Checking installations against approved drawings and specifications
- Verifying equipment and materials match the approved schedules
- Inspecting pipework, ductwork, cable containment and fixings
- Witnessing pressure testing, flushing and insulation
- Reviewing fire stopping around services penetrations
- Checking plant room layouts, access and maintainability
- Witnessing commissioning of HVAC, electrical, fire and controls systems
- Reviewing test certificates, O&M manuals and record drawings
- Attending progress meetings and issuing inspection reports
Question: When should an M&E Clerk of Works be appointed?
Answer: Ideally the Clerk of Works is appointed before mechanical and electrical first-fix begins so that early installation quality, coordination and fire stopping can be checked. Inspections then continue at agreed intervals through second fix, commissioning and handover. Part-time appointments, such as one or two visits per week, are common and cost-effective for most projects.
Question: How does an M&E Clerk of Works differ from an M&E consultant?
Answer: The M&E consultant designs the systems and may provide periodic site visits to review general compliance with the design. The Clerk of Works provides more frequent, detailed and hands-on inspection of workmanship and installation quality. The two roles are complementary, and the Clerk of Works will typically report to both the client and the design team.
Question: What reports does an M&E Clerk of Works provide?
Answer: After each visit the Clerk of Works issues a written inspection report with photographs, identifying compliant work, defects, non-conformances and outstanding items, and tracking their close-out. At the end of the project a final report summarises the installation quality and any residual issues to be addressed before handover.
Question: Can an M&E Clerk of Works assist with commissioning and handover?
Answer: Yes. Witnessing commissioning is one of the most valuable parts of the role. The Clerk of Works verifies that systems are balanced, controls operate correctly and performance meets the specification, and reviews commissioning certificates, test results, O&M manuals and record drawings before practical completion. This helps to avoid the performance gap between design intent and actual building operation.
