Reviews from the Google profile Coutts Electrical publish. They are not location-tagged, so none is presented as a job in this town.
I had a bank holiday DIY emergency and needed someone to come out and make it safe and get our power back on. Coutts answered and Max was round within a couple of hours. Really easy communication, no hassle and easy to deal with, will definitely be using them for future jobs.
Very happy with electrical work undertaken by Max of Coutts Electrical, and his team. They installed an electric radiator and new light in the kitchen. They offered advice and were professional and tidy. Would highly recommend.
Max responded very quickly to my request to review an electrical fault and efficiently dealt with the issue. I’m delighted that I’ve found Max and will definitely be calling upon him for any future electrical work.
