Engineer rang before he came, and came as arranged. Polite and professional. I was advised when booking that servicing 2 boilers, one gas water heater and two gas hobs would take 3 hours. I learnt two days before they came it was going to cost £370 plus VAT, which I thought was expensive but for 3 hours work plus travelling wasn't extortionate. However engineer was only there for an hour and half including completing paperwork. Which proved astronomically expensive per hour, especially as our church is struggling financially to survive. Would I use them again ? No I'll be trying to find someone cheaper.
