Fuse box repair costs depend on the fault type. A single MCB or RCD replacement typically costs £80–£180 including the part and an hour's labour. More complex faults requiring extensive diagnostic testing may cost more. We always confirm the cost before proceeding with any repair work. Pricing is consistent across all East London postcodes.

An MCB that keeps tripping is doing its job — it has detected an overcurrent or fault condition on that circuit. Common causes include: an overloaded circuit (too many appliances drawing too much current), a short circuit in a connected appliance, damaged cable insulation, or a faulty MCB that has become over-sensitive. We test the circuit systematically to identify the exact cause.

RCD tripping in wet weather almost always indicates moisture ingress — either in outdoor wiring (garden lighting, outdoor sockets, or external fittings), in a bathroom fitting, or in underground armoured cable. This is particularly common in East London terraces and maisonettes where older wiring or external cable runs may have degraded. The RCD is detecting current leaking to earth through the moisture. We use insulation resistance testing to locate the affected section of wiring.

You can try resetting an MCB by pushing it firmly back to the ON position after it trips. If it immediately trips again, there is a genuine fault on that circuit and you should not keep resetting it. Leave it in the tripped position and call us. Repeatedly resetting a tripping MCB on a faulted circuit can damage wiring and appliances, and may create a fire or shock risk.

A tripping protection device means your electrical installation is detecting an abnormal condition. While the tripping itself is a safety mechanism, the underlying cause needs to be investigated. An overloaded circuit, damaged cable, or leaking appliance left unaddressed can cause fire or electric shock. We recommend booking a diagnostic visit promptly.

If your main switch is in the ON position but all circuits are dead, check whether your supply has been interrupted externally (contact your network operator's emergency line on 105 for power cuts). If the street has power but your property is completely dead, it may be a supply fault at your meter or incoming supply — this requires your DNO (Distribution Network Operator) to attend, not an electrician. If some circuits are dead but others are live, this is likely an internal fault we can diagnose and repair.

We advise honestly on this based on what we find. If the board has a single easily-replaceable fault, repair is usually the right choice. However, if the board is outdated (rewirable fuses, no RCD protection, or over 25 years old), has had multiple failures, or is failing an EICR, a full consumer unit replacement provides better long-term value and significantly improves safety. Many East London properties still have old fuse boards — we provide both options and let you decide.

Yes — we aim for same-day fuse box repair across both Tower Hamlets and Newham for non-emergency faults. For emergency situations such as a total loss of power or burning smell from your consumer unit, we respond immediately at any hour. Call 07852 280 518 and we will confirm our earliest available slot based on your location.

Yes — fuse box faults in HMOs and rental properties require particular attention because a faulty consumer unit can affect multiple tenants simultaneously and may have compliance implications for the landlord. We repair all consumer unit faults in rental properties across East London, issue the correct electrical certification, and can carry out a full EICR at the same visit if the landlord requires it for their Electrical Safety Standards (Private Rented Sector) obligations.

Yes — we cover Hackney (E8 Dalston, E1/EC2 Shoreditch) and Waltham Forest (E17 Walthamstow, E10 Leyton) for same-day and emergency fuse box repairs. These areas have a high proportion of Victorian and Edwardian properties with older consumer units that are more prone to faults. Call 07852 280 518 for the fastest response in your area.

A fuse box repair involves replacing a specific faulty component — such as a single MCB, RCD, or RCBO — while leaving the rest of the board intact. A fuse box replacement (consumer unit upgrade) involves removing the entire board and installing a new one. Repair is appropriate when the board is fundamentally sound and only one component has failed. Replacement is recommended when the board is old, lacks RCD protection, has multiple failing components, or is failing an EICR. We assess and advise honestly on the best option for your specific situation.

Yes — we repair consumer units and distribution boards in commercial properties across East London, including offices, retail units, restaurants, warehouses, and HMOs. Commercial fuse box faults can have significant business impact — loss of power to a retail unit or office is a genuine emergency. We provide 24/7 emergency fuse box repair for commercial customers across all East London boroughs, including Canary Wharf, Shoreditch, Stratford, Barking, and Ilford.
