Commercial electrical supplies vary according to building layout, connected machinery and the existing circuit design. Before replacement, it is important to assess the board, protective devices, labels, cable arrangements and available capacity.

• Review the board and circuits serving your business.
• Discuss the suitability of protection and any necessary alterations.
• Plan electrical isolation and minimise avoidable disruption.
• Complete installation, checks and relevant documentation for the agreed scope.

A new board does not automatically solve faults elsewhere in the wiring.

At a shop or commercial workshop in Yate & Chipping Sodbury, a board may serve distribution to shop floors and stockrooms. It helps to identify circuits that cannot be interrupted without affecting staff or equipment and to clarify access to the electrical cupboard.

Tell us when the building is occupied and whether other businesses use the same supply. Shutdown arrangements need to be agreed before any work starts.

Existing EICR reports, circuit schedules and safely taken photographs can help us plan a survey. Never remove electrical covers or approach exposed conductors to take pictures. A visit may be required to check the installation, determine suitable equipment and confirm the work needed.

The quotation should identify materials, isolation, testing, documentation and any exclusions. Work on specialist machinery or unusual hazardous installations must be assessed separately.
