Been with bulb 12 months now on my pre payment meter and it doesn't seem to be the case when they say you save money , im only on electric but considering I'm in a 2 bedroom flat I'm using more than my mom does in her 3 bedroom house per month, and then also been lied to by saying we are untitled to a cold weather payment due to a child under the age of 2 and being on UC benefit as I'm on a low income payed job it doesn't help everytime I top up they take money from me even if I'm in credit.
