We've been with British Gas for years but the standard of work (especially on the plumbing side) has gone downhill since that side of the business was fulfilled by dynorod culminating in them taking 4 attempts to fix our leaking toilet (which they cause to leak in the first place) and culminated in us needing (and them paying for) a new bathroom floor and a new kitchen ceiling.
Unsurprisingly i want to find a new provider (if nothing more than for the plumbing cover). Who do people recommend that use plumbers that actually know what they are doing?
