National Schedule of Rates – Mechanical Services 2026/2027

The National Schedule of Rates – Mechanical Services 2026/2027 is a specialist cost and pricing reference providing rates for mechanical services maintenance and repairs, together with dedicated rates for Builders Work in Connection (BWIC).

Designed for use across most conventional building types, the schedule provides comprehensive cost guidance for mechanical services and associated building works. It is a practical reference for professionals involved in maintenance, repair, estimating, cost assessment, property management and building services.

Mechanical Services & BWIC Rates

The Mechanical Services Schedule of Rates provides rates for mechanical services maintenance and repair works, together with Builders Work in Connection (BWIC) rates associated with mechanical and electrical installations.

The inclusion of dedicated BWIC rates makes the schedule particularly useful when mechanical services work requires associated alterations, repairs or other works to the building fabric.

This allows users to assess the cost of both the mechanical services work and the associated Builders Work in Connection as part of maintenance, repair and alteration projects.

Builders Work in Connection (BWIC) Rates

A key feature of this schedule is its inclusion of rates for Builders Work in Connection with Mechanical & Electrical Installations.

BWIC covers building works carried out in connection with mechanical and electrical services installations. Such works may be required when services are installed, altered, repaired, maintained or replaced and associated modifications to the building fabric are necessary.

The inclusion of BWIC rates provides a valuable cost reference for assessing associated building works alongside mechanical services maintenance and repair requirements.
