Graeme came out to give us a quote which was a fair one. We used a different company only because of a personal recommendation.

I cannot find a single fault with these guys. I took a bit of a flyer by going with a company I had no dealings with and only a recommendation from this site, but it paid off. They were out to see the job in no time and gave us a date for the work just a few days away. They fitted a quality boiler for a very competitive price. They were in and out in a single day with minimum fuss. We are very happy with the boiler. Quality of service was excellent. Everything was explained and they came through on all their promises. I would definitely recommend them as quality tradesmen to trust. Thanks.

Sean has done an excellent job in replacing my combi-boiler. He responded very promptly to my request for an estimate which was by far the fairest out of 4 local tradesmen. He's a pleasant, polite young man and a VERY hard worker--didn't even stop to drink his cups of tea !! I am recommending him to all my friends.

DNA was the only company that responded to my request to fit a new toilet. I was flexible regarding the fitting time and Joe kept me informed of his availability to complete the job. Very reasonably priced compared to quotes from British Gas and HomeServe. Superbly neat installation including boxing in of pipework.
