Scottish Power was the most recent of the Big Six to cave in on cost, cutting its gas prices by 5% for 1.4 million of its customers from February 27.
The dominoes began falling when EDF dropped its standard gas prices by 5%. It was followed by British Gas that announced a 5% cut to single rate electricity bills. Next was SSE, which pledged to cut household gas prices by 4.5% from March 26.
npower and E.ON were the fourth and fifth big providers to move, cutting their prices by 5% and 6% respectively.
The benefits of switching
But even post the price cuts there are still several types of customers who could benefit from changing the deal they are on.
Recent research from MoneySupermarket found that consumers could still reduce their annual energy bill by 22% if they switched from their traditional energy supplier to the best deal. That's £282 per household and a staggering £3.5 billion worth of savings nationally.
However, gas and electricity market regulator, Ofgem says the majority of gas and electricity customers have never switched their providers. And this isn't surprising given how confusing it can be to determine whether you'd be better off by switching.
To help you decide, we take a look at just who could save money by switching their energy providers or tariffs.
If you have separate gas and electricity providers and standard prices for each
If your gas and electricity comes from different providers, you're probably paying top whack for your energy.
Getting your energy this way means that you'll be on standard prices for both your gas and electricity, which won't be the cheapest - and you'll be missing out on a dual fuel discount. You may also be able to get further discounts by paying by direct debit.
If you have inherited you provider and pay the standard price
If you simply stuck with the provider you 'inherited' from the previous owners or tenants when you moved into your current home, you could save by switching.
You may already get a dual fuel discount if the previous occupants switched to one provider for both gas and electricity, but you could still be able to save even more money by switching to a more competitive provider or tariff.
If you moved supplier after privatisation and pay the standard price
Many householders moved either their gas or electricity when the energy industry was privatised, so that they had a single provider for both utilities.
If you are among them, you will already benefit from a dual fuel discount, but will likely still be paying standard prices. Switching to a more competitive tariff and paying by direct debit could save you money.
Other available discounts
If you pay by direct debit on a monthly, rather than quarterly, basis you will qualify for a discount, while managing your account on the Internet with an online tariff will also reduce your bills. How to get the cheapest overall energy
Remember that the Big Six suppliers all put their prices up last summer, so the latest wave of price cuts don't actually negate the price hikes of 2011. If you went for a fixed-rate deal before the price hikes, then it won't be beneficial for you to switch at the moment.
If you're considering fixing your deal at the current prices because they have fallen, it might be better to wait because it is possible (though unlikely) that prices could drop further.
In summary, you can make sure you get the cheapest energy possible by getting both your gas and electricity from the same provider, managing your account online, paying by direct debit on a non-standard tariff - and by switching to the most competitive provider or tariff on the market.
