Happened to have a conversation with my Gran where it turns out she had her boiler replaced and the old one removed by BG, total cost £3,000. Plus they charged for an Energy Performance Certificate (EPC).
I looked online and it took seconds to find the same boiler new for around £700. We had our boiler removed and replaced last year due to a leak by a regular Engineer (not BG) and total cost was £1,900.
I have written to BG complaining about the cost, the unnecessary EPC (she didn't even know she had had it done) and for a breakdown. They wrote back basically saying no to a breakdown and that I could contact a Solicitor but they didn't think I would gain anything.
I then wrote to the energy company Ombudsman they have have written back saying it's nothing to do with them either.
I would appreciate any thoughts as to where to go from here as I definitely think they have overcharged her.
