Electrical and plumbing work in-house
The appropriately qualified team handles both parts of the agreed job through one point of contact.
Specialist Services
No hot water, repeated tripping or a system that needs replacing? AB Electrical assesses the fault and repair options. Our appropriately qualified in-house team handles the electrical and plumbing work required.

A failed element or thermostat is different from a damaged tank. We assess the fault, tank condition, service history and repair cost before recommending a repair or replacement.

AB Electrical handles electric and heat-pump systems, electrical work for solar hot water, dedicated circuits and changeovers. The appropriately qualified in-house team carries out the electrical and plumbing parts of the agreed job through one point of contact.
No hot water is disruptive, but it does not always mean the system is beyond repair. For replacement, the household’s demand and the available installation space also need consideration.
Keep away from wet electrical equipment, burning smells or a repeatedly tripping system. Do not open covers or reset it again. For smoke, fire or immediate danger, leave and call 000. A shock or tingle from taps or metal fittings needs immediate emergency and distributor advice, not a routine booking.
You deal with the same electrician throughout your electrical work. If a fault is caused by our installation or repair workmanship, we put it right at no extra charge.
The appropriately qualified team handles both parts of the agreed job through one point of contact.
The recommendation accounts for the fault, tank condition, repair cost and suitable replacement options.
Many component repairs can be completed on the visit. Parts availability and additional faults may require follow-up work.
Operation is checked and the work explained, including any remaining work or follow-up needed.
Repairs are often completed in one visit, typically one to three hours, where the fault and available parts allow. New installations are typically completed in a day; required extra work can change that timing.
The qualified team isolates as needed and checks the electrical supply, components and plumbing.
Compare a component repair with replacement where appropriate. Planned work is quoted in writing; urgent faults are discussed on the call.
Complete the agreed electrical and plumbing work in-house, with any extra circuit work included in the scope.
Check operation and explain the work, system controls and any follow-up required.
