Not reliable as the appointment changed many times in short notice. The person arrived with no tools due to many issues and had to complete the work in a second appointment . Not recommended.

Putting your trust into a company when dealing with gas safety regulations is daunting. Not only do you need to be confident and safe in your choice but also feel you receive an honest quote. I had so many Engineers walk through my door and as soon as A&C arrived, I trusted them. I went with my gut and they were excellent! I have no hesitation in recommending this company to take care of you and your family. Thank you!

Simply the BEST! I would give them 10 stars if I could. Outstanding work, outstanding service, outstanding quality, outstanding level of detail and outstanding people. Shadi, Rabee and team, not only sorted out my leak, they undertook a major project to repipe my home, fix electrics, paint , put up new storage space, carpentry work , fixing walls etc. The first time that I have seen any builder finish weeks ahead of schedule. They are extremely well organised and operate to the highest degree of precision.

Bayley replaced a badly damaged bath drain for me which had caused a leak under the bath. He did an excellent job and thoroughly tested the drainage system, fixing and adjusting connections where needed. He also fitted a new shower tap for me at the same time. Bayley was friendly and polite and I had total confidence in his ability within a few minutes of his arrival. I would not hesitate to recommend him for plumbing work.

1. Turned up 1.5 hours late to my property. Didn’t even have the courtesy to call until 1 hour had passed. 2. Didn’t have the right tools to complete the job. Took one look at it, banged a hammer a few times, and said it can’t be done (for the record - the job was subsequently completed in about 20 minutes by a proper tradesman) 3. Left my property after 10 minutes. Then demanded I pay £80 call out charge, in spite of having done absolutely nothing and arriving 90 mins late. STAY AWAY from Electro Flame.
