Little-known supplier has topped the energy best buy tables

Challenger GB energy supply launches cheapest energy tariff

There's a new name at the top of the energy best buy tables, and it's one you may not be familiar with.

GB Energy Supply has stormed into top spot with the Premium Energy Saver tariff, which will set back the average user just £870 a year, much cheaper than the rest of the market.

Who is GB Energy Supply?

Established only last year, GB Energy Supply is based in Broughton, near Preston.

The firm says that it can keep its prices low by having very little overheads, preferring to grow its business through word of mouth rather than popping up in the media.

GB Energy Supply is a simple, single tariff provider which doesn't charge exit fees.

However, as it's a new company it hasn't had a lot of time to build a customer base or develop much of a reputation.

It seems that the Big Six are falling further and further behind their smaller competitors with only npower and Scottish Power appearing in the top 10. First Utility and Extra Energy dominate the rest of the table with their competitive deals.

Make sure you find the best deal for you depending on what's available in your area as well as your average energy consumption. The best way to do this is by shopping around - why not start with the energy comparison centre?
