I would also endorse John Powers. We had a broken boiler before Christmas and called several people. I then called John who gave a reasonable quote and said he could take a look that evening which he did. He was professional, reliable and skilled. I would highly recommend using John.
Another recommendation. John has done a couple of jobs for me and been brilliant both times. Good prices and quick to respond.
John sent a member of his team very promptly when we had a leak in our bathroom. They were very efficient and sorted out the problem. I would certainly recommend using them .
I would also like to recommend John Powers. He came round on Saturday after my boiler stopped working on Friday night. He had the parts ready and did a great job cleaning the old system and issuing me with a certificate that no other plumbers were ready to do. I will also ask him for a quote to change the whole system.
