Sorry for late review,slipped my mind!
In January of 2015 I got Aidan to replace a leaky copper cylinder. He came on time when he said he would and immediately got stuck into the work. He kept at the job until it was done and didn't waste time at all. In all it only took him about 2 hours to remove and replace the cylinder.
The only delay was waiting to siphon out the water from the cylinder (which is a slow job anyway).
I was very impressed by his knowledge and as I'm familiar with building work, I knew he was correct in all he said! Unlike other tradesmen who try to create extra work for themselves and charge crazy prices, I found Aidan to be very genuine and down to earth in his price. I will have no trouble getting him again for other jobs that crop up.
Note to public-for doing a straight forward replacing a copper cylinder-if a plumber tries to tell you its going to take all day and cost an arm and a leg to do the job-run away and phone Aidan instead!
