Sorry for the delay in leaving feedback but it is best to wait until the job matures a little I think.
Six weeks on from completion everything is still looking good, no leaks and I am very satisfied with Kieran's work.
He was punctual, polite, knowledgeable and keen to offer advice. He work hard, quickly and with considerable skill.
I lost touch with my last plumber, I think he retired, so Kieran is now my new plumber of choice and I have at least one job that if he is not too busy he will be doing soon.
Thanks Kieran, see you soon
Mike
