Danny was thorough and knowlegable in his assessment of what needed doing for my boiler replacement, gave a competitive quote, was punctual and completed the job at the agreed time. There were a couple of quirks in my setup which required a little extra work doing but Danny did these at no extra cost to me, even when he had to get an electrician in. Another point worth mentioning is he is a registered Main dealer so you get a longer warranty on the fitted boiler. Danny was also pleasant throughout - I would definitely use GASolution again or recommend to others.
