I am a widow (previously married to a non-DIY person). I have a contract with BG for virtually anything that goes wrong in my home - about £750 per year.
They use local plumbers, Dynorod, electrical people, manufacturers' service people .... there is no way that I would transfer from BG to a new company like PRIME TIME PLUMBERS.
Vana's marketing was excellent - she really hit the market. She even admitted that she needs a new venture-capital firm to come on board - as well as Lord Sugar. (Did you see Lord Sugar running his hands at the end of that presentation?)
