With so many gas and electricity suppliers in the energy market, you’d be forgiven for feeling a bit confused. That’s why we specialise in taking the hassle out of your hands and switching you to great deals year after year. We find energy deals from a wide range of suppliers including, the Big Six, medium to small-sized providers and even ‘green’ energy companies.
The Big Six UK Energy Suppliers
The Bix Six Energy suppliers in the UK are British Gas, E.ON, EDF Energy, nPower and SSE. Together, they’re responsible for supplying 74% of UK households with gas and electricity. While these companies dominate the supplier market, back in 2004, the Big Six energy providers accounted for all of Great Britain's energy customers.
