Excellent. They came out on a Sunday evening to a job caused by the external electricity supply. They were reliable and pleasant to deal with. Thanks to them my tenant was very satisfied.Trustindex verifies that the original source of the review is Checkatrade.
Great Service. Richard and young apprentice arrived on time assessed the issue and quickly concluded that the issue was caused by old lights which were faulty. They replaced with new lights and tidied up all the cabling. They were polite and very clean. Would recommend them and use their services again.Posted on Google

Some common questions we answer
Why is my circuit breaker tripping frequently?
This could be due to overloading the circuit, a short circuit, or a ground fault. Mostly, to resolve this, you can basically avoid overloading the circuit. If the issue persists, contact us immediately.
Why are my lights flickering?
Flickering lights can be caused by loose connections, faulty switches, or overloaded circuits. Check for loose connections and try replacing the bulb. If the problem continues, contact us immediately.
Why is my electrical outlet making noise?
Noisy outlets can be caused by loose connections or faulty wiring. Avoid overloading the outlet and unplug any devices connected to it. If the noise persists, contact an electrician.
My electric heater isn’t working. What should I do?
First, check the thermostat settings and ensure the circuit breaker is switched on. If the issue persists, it may be due to a faulty thermostat, wiring problem, or a damaged heating element. Consult our local electricians for inspections and repair.
