"Fantastic service. Honest, reliable and genuinely goes above and beyond to make sure you get a repair that is not going to cost you a fortune. Nigel sourced a second hand reconditioned part which saved us a huge bill. Really appreciate the honest approach."
"Phillips Auto Electrical was recommended to fix a crazy problem with my Ford Transit Custom — every time it rained or was damp the traction control light would come on and the temperature gauge would stop working. They diagnosed and fixed it when others couldn't."
"Ian from Call Out Electrical conducted an inspection of the electrical system on a new house purchase for me. He was very responsive and flexible, hard working and highly competent. He's also a lovely guy who went the extra mile. Highly recommended!"
