 Trustindex verifies that the original source of the review is Google. We first met Danny the boss who was so very helpful and understanding and we booked DT Ekectrical in for the job. We then had George from DT Electrical change old storage heaters for eco panel ones. He was so incredibly efficient, organised and cleaned up after himself. We have already booked our next job with DT Electrical. Superb service and totally recommend.
