Simply Electrical Contractors

Find the cause before replacing parts

Repeated tripping, a dead circuit or an intermittent fault can have several possible causes. Effective fault finding uses inspection, testing and a logical process to narrow the problem down rather than guessing or repeatedly replacing components.

Simply Electrical Contractors investigates electrical faults across London in homes, rental properties, shops, offices and other premises. Useful information includes when the problem started, what was in use at the time and whether recent building or electrical work has taken place.

Once the fault is located, the electrician will explain what has been found, any immediate safety action and the options for repair. Where further work or replacement parts are required, that next step is made clear.

Work this service can include

  • RCDs, RCBOs or breakers that trip
  • Sockets, lights or circuits with no power
  • Intermittent electrical problems
  • Damaged accessories and loose connections
  • Faults affecting homes or operational premises

Common questions

Useful information before you enquire

For advice about a specific property, contact the team with the postcode and job details.

Common causes include a faulty appliance, damaged cable, moisture, an overloaded circuit or a problem with a protective device. Testing is needed to identify the actual cause.

No. Repeatedly resetting a circuit without finding the cause can be unsafe. Disconnect obvious suspect appliances and arrange professional testing.

Yes. Share as much detail as possible about when the fault occurs, weather conditions, equipment in use and any recent changes to the property.

Straightforward repairs may be possible once the cause is confirmed. More extensive work or specific parts may require a separate quotation or return visit.
