Saw this in Metro newspaper yesterday and sounded like a fantastic deal; you limit the risk of getting into trouble during the coldest months by covering your central heating from 30th September until 31st March for £2 a month, and all you'd pay (God forbid!) is just £99, including labour and parts!!
Ad says 'Guaranteed same or next day response if you have no heat or water'.
Came to check the spec online and just realised that this special price is only available over the phone at 0845 678 8131.
Online prices are £160 in London and £130 elsewhere.
