National Schedule of Rates – Electrical Services 2026/2027

The National Schedule of Rates – Electrical Services 2026/2027 is a specialist cost and pricing reference covering electrical services maintenance and repairs, alterations and Builders Work in Connection (BWIC).

Designed for use across most conventional building types, the schedule provides comprehensive cost guidance for electrical services and associated building works. It is particularly suited to professionals involved in maintenance, repair, alteration, estimating, cost assessment and the management of building services projects.

As well as electrical services rates, the schedule includes dedicated rates for Builders Work in Connection with Mechanical & Electrical Installations (BWIC), providing cost guidance for the building works required in connection with services installations, alterations and maintenance.

Electrical Services & BWIC Rates

The Electrical Services Schedule of Rates brings together rates and cost information covering electrical services maintenance and repairs, associated mechanical and electrical services, and Builders Work in Connection (BWIC).

The inclusion of BWIC rates makes this schedule particularly useful where electrical or building services work requires associated building alterations or remedial works. This can include work required to accommodate, modify, repair or reinstate the building fabric in connection with mechanical and electrical installations.

The schedule is therefore suitable for assessing both the services work and associated building work that may form part of a maintenance, repair or alteration project.

Builders Work in Connection (BWIC)
