Due to rising costs, many providers have removed their deals from the market, so we're unable to switch you right now

Wait! Read this before you get quotes…

Spiralling energy costs have forced many suppliers to remove their tariffs

What this means for you:

  • We probably can’t save you any money right now because there aren't enough tariffs to compare
  • We hope we can help you save in the future – but we don’t know when that’ll be
  • If you go direct to energy suppliers’ websites you might find better deals

We believe in always doing the right thing for our customers – which is why we’d rather tell you now,
so you don’t waste time quoting if we probably can’t help you.

Npower was one of the UK’s ‘big six’ energy suppliers. It supplied gas and electricity to millions of people across the UK.

The company has been acquired by E.ON, so it’s currently in the process of handing over all its existing customers. Npower isn't accepting new customers, but you can still get a great energy deal from another provider by comparing energy quotes.

Npower tariffs: What did they offer?

Npower offered a range of tariffs, including:

Standard variable tariffs (SVT)

An SVT means the price you pay for energy could rise as well as fall. There’s no exit fee for switching tariffs or suppliers.

It’s usually the most expensive type of tariff to be on.


On a prepayment tariff, you pay for energy before using it. You can have a gas or electricity meter, or both. You top-up a meter using a key or card.

A prepayment tariff usually puts you on an SVT. This can be more expensive than a fixed energy deal.

Fixed-rate tariffs

Fixed-rate tariffs lock in a fixed price for a set amount of time – usually 12 to 24 months. You must agree to have a smart meter installed in your home to be on one of these tariffs.

You’ll probably be charged per fuel if you want to leave a fixed-rate deal early. You won’t be charged if you’re still in the 14-day cooling-off period though, or if you’re in the 49-day ‘switching window’ before the contract ends.

Make sure you consider exit fees when comparing gas and electricity prices.

Dual fuel tariffs

You could get a discount from choosing one supplier for both your gas and electricity.

As well as saving money on energy, a dual fuel deal can be more convenient. You’ll have just one bill to pay and one supplier to deal with.

Green tariffs

Green fixed-rate tariffs are a good choice for the environmentally conscious as some or all of your energy will be generated using renewable sources, like wind or hydro power.

Npower isn’t accepting new customers and current customers are being moved to E.ON.

You can still use our energy price comparison tool to find tariffs relevant to you and start comparing prices.

There’s no set price for gas and electricity. It depends on how much you use. So, a family of four would generally have a bigger bill than someone who lived on their own. Also, a bigger home with more rooms tends to cost more to heat than a flat, for instance.
