Where’s the job?

Scope of Works

• Inspect consumer unit and hot water fuse or fused spur to identify the failed component

• isolate and test the hot water circuit using appropriate equipment and PPE

• remove and replace the failed fuse, cartridge or fuse link with the correct rating

• replace or fit a new fused spur/isolator where required and secure connections

• test the circuit and RCD/MCB operation, label the work and restore supply

• provide a brief report and advise if further wiring or immersion heater work is needed

Typical Cost

Time on Site

Most simple fuse replacements take 30 minutes–1 hour on site; jobs that include tracing wiring faults, replacing an isolator or working in lofts can take 1–3 hours and may need a second visit.

Questions to Ask Your Tradie

• are you a qualified electrician and registered with a competent person scheme

• will you provide an electrical safety certificate or minor works certificate for the job

• what rating fuse will you fit and will you explain why that rating is correct

• if you find damaged wiring, what are my options and ballpark costs for repairs

• will you need loft access or work at height and will that add to the price

• do you carry common replacement parts or will you need to order anything that could delay completion

How to Avoid Surprises

• ensure clear access to the consumer unit and hot water cylinder or cupboard

• let the electrician know about loft access, tight cupboards or concealed cylinders in advance

• check nearby parking or loading restrictions for a van and tell the tradesperson if permits are needed

• keep pets away from the work area and remove stored items from cupboards to speed the job

• ask about potential follow-up visits for wiring repairs and budget for extra costs if faults are found
