Where’s the job?

Scope of Works

• Inspect and test heater elements, thermostat and control wiring to identify the fault

• Remove heater cover, check internal terminals for corrosion and clean where safe to do so

• Replace faulty heating elements, thermostats, timers or control modules and refit covers

• Repair or replace damaged mains wiring and connections and test earthing and RCD operation

• Run electrical safety tests, demonstrate operation and advise on controls or replacement options

• Remove and responsibly dispose of failed parts and provide a short written report and next steps

Typical Cost

Time on Site

Diagnostics typically 1–2 hours; a simple element or thermostat swap usually 1–3 hours; a full heater replacement 3–6 hours. Restricted access, corroded wiring, needing a second electrician or waiting for ordered parts will extend time

Questions to Ask Your Tradie

• Are you registered with NICEIC or NAPIT and insured for electrical work

• Can you provide an itemised quote including labour, parts and disposal before you start

• Will you isolate the circuit and issue an electrical safety test or confirmation on completion

• Do you expect to need replacement parts that require ordering and what are the lead times

• What guarantee do you provide for labour and parts and will you supply paperwork

• Could access, scaffolding or permission from a freeholder be needed for this repair

How to Avoid Surprises

• Clear the area around the heater and ensure easy access to the consumer unit

• Reserve parking close to the property and tell the tradie if access is via a communal corridor or loft

• Tell the tradie if the property is leasehold or a flat so they can check freeholder consent if needed

• Flag any known asbestos or unusual panelling around the heater so the engineer can plan safely

• Secure pets and provide good lighting so work can proceed without delays

• Ask how long parts will take to arrive and whether a temporary fix is possible while waiting
