 'Spoke to Steve on the phone initially to try and gauge the problem. His son Jordan (family business) arrived on the way home from a local job. Identified faulty RCD was the problem almost immediately, ordered replacement parts, replacing asap. Really friendly, took time to listen, courteous on site. Sorted a problem that is known to be a pain so efficiently. Price was excellent too! Also refitted my induction hob FOC that another company had declared was the source of the problem and had left dangerously unsafe. Cannot recommend highly enough, and will be my go to call for all future.'
