We have no idea who to use to fit our new boiler, being 'corgi/gas safe' registered is not enough of a reassurance after a horrible scam pulled off by a supposed registered plumber last week.
We have a few quotes, B.gas very pricey but the only ones we trust. Leakbusters seemed very competent we have yet to receive a quote.
we live in NW london and have a really old system to change to combi.
any experiences of good middle-range companies?
thankyou
