Alf gave us a price and gave us a starting date. They came on the expected day and told us exactly what was going to happen each day. we had a new boiler and tanks etc were removed so it was a messy job. Ben went out of his way to minimise the mess and even found a small gas leak on my hob which was mended. They finished when they said they would, even working late to finish the job. Alf checked that everything was ok a couple of days after. An impressive job, thank you.
