Customer Testimonial

John was quick to respond to my fault-finding request of faulty dimmer lights and did not push for an upfront ‘call-out fee’ as others do. Fitted it in to suit my time as a full-time worker and quickly discovered it was a faulty switch. Which was promptly fixed. Thank you

Client Reviews

John replied to the message quickly and managed to carry out the EICR at ease. He found two faults, and the dimmer switch was faulty, which he fixed all on another round. Got the report right after.
