Electrical fault finding and connections for electric hot-water systems. Plumbing, gas work and replacement tanks are quoted by the appropriate separate trades.
The work we do
Find the fault before replacing the system
No hot water does not always mean the tank needs replacing. A supply fault, failed heating component or control problem can produce similar symptoms. We assess the electrical side and explain whether a repair is suitable or a hot-water specialist needs to be involved.

Your property
Planning the work in Sydenham
For older houses, terraces and cottages in Sydenham, access behind walls and above ceilings matters as much as the fitting or equipment being installed.
Electrical fault or another part of the system?
The existing supply, isolation and protection must suit a replacement unit. Appliance labels and a photo of the switchboard help identify the electrical work needed.
Electrical or plumbing?
Tell us whether the system leaks, has no power or stops heating. Tank, pipework, valve and gas work are outside this electrical service.
Repair suitability
We consider the diagnosed fault, compatible parts and the condition of the unit before recommending electrical repairs.
How it works
From cold water to a repair plan
Assess the electrical fault
Check the reported symptoms against the system model, supply circuit and heating controls. The diagnosis establishes what can be repaired electrically.
Confirm parts and scope
Agree compatible replacement parts, the electrical work and price. Tank, plumbing or gas work is identified separately so the repair has a clear boundary.
Test and explain the result
Check the repaired circuit and heating controls, then explain normal operation, reheating time and any further work needed.

Hot-water electrical questions
Do you replace hot-water tanks?
This service covers electrical work. Tank replacement, pipework, valves and gas work need the appropriate hot-water or plumbing specialist.
Why is the water cold when the system appears to have power?
An electrical supply indicator does not confirm that the element or thermostat is working. Supply controls, wiring or the heating components may need testing; the tank or plumbing can also be involved. Tell us the system model and symptoms so we can establish whether an electrical assessment is appropriate.
What if the hot-water circuit keeps tripping?
Do not keep resetting a switch that trips. Leave the affected circuit off and arrange an assessment. A fault in the element, wiring or another component needs diagnosis before a repair is chosen. Keep clear of wet or damaged electrical equipment.
Can you check the electrical connection for a replacement system?
Yes. Send the proposed system model and electrical requirements before installation. We assess whether the existing circuit, isolation and protection suit it, and agree the electrical work separately from tank installation or plumbing.
What access should I arrange for the visit?
Keep the work area and switchboard accessible, tell us about parking or locked gates, and arrange entry to any rooms involved. Mention restricted ceiling or underfloor access when enquiring; you do not need to enter these spaces yourself.
