Doing my annual trawl through energy price comparison sites, the company that's come up twice as being the cheapest is called "Spark" . I've never heard of them, has anyone used this supplier, would they recommend them ?
We have a good tariff with nPower at the moment. But nPower have been useless. We've not had a bill generated in over a year! We chased this many many times. Even if they remain cheaper we will move when the discounted/locked-in period ends.
