The money Expert advises you should change Energy companies so I have save over £200 per year after a 2 hour call to SSE new call centre offshore which would usually have taken 3 minutes in the old days been with them 15 years - googled around it's so easy to do went with Octopus which voted them best provider last year too all done online too.....no smart meter need or if you have one they transfer it over no exit fee either...
