Been with Atlantic Gas Electricity (trading name of Scottish and Southern Energy) for 5 years now ,never had any problems with billing and they have always refunded any over payments every year. I usually get a customer loyalty free months gas electricity every January but they must have stopped this perk this year :(. Overall happy with service customer service is excellent although a couple of new smaller energy companies have entered the market last couple of years and their prices are slightly cheaper .

Atlantic recently wrote to me with their price increases so I went on a few comparison websites which all came up with big savings by switching to First:Utility. It's a hassle to switch suppliers so I rang Atlantic to check if there were any better deals they could offer. Southern Electric, of which Atlantic are a division, have an on-line tariff called 'Go Direct' (which they don't advertise!). So they have moved me on to that, saving me around 20% annually. This is not far off the saving I apparently could have achieved by switching, plus the First:Utility tariff that the comparison websites all used was a variable monthly payment for your actual usage, not spread out over the year, so they weren't actually comparing like-for-like. I've found this is often the case with these price comparison websites. The sales advisor I spoke to at Atlantic was very helpful, unlike the call centre at First:Utility who took ages to answer and then couldn't really be bothered. After making the change and sticking with Atlantic I reivewed First:Utility - the very clear message from virtually all reviewers was 'stay well clear'. Their customer service seems to be non-existent whereas I've always had a good experience with Atlantic. It's a shame they don't publicise this cheaper tariff, but then I suppose it's not in their interest - just like the banks!

We've been with Atlantic for a good few years now and I do rate them (have both our gas and electric with them). Thumbs up for paperless billing, always quick to send out a revised bill if they send you an estimated version and we've received a loyalty discount in the form of cashback straight into our account.

So long as a company such as Atlantic Electric and Gas remains cheap and service good and customer relations good then I will continue forever. Mess up and I move.
