Martin Lewis has urged people to check whether they're eligible to save £200 before energy bills surge in price.

In his weekly Money Saving Expert newsletter, the finance guru said wholesale energy prices have gone up which will have a significant impact on people's energy bills.

With the cold winter months and many people continuing to work from home as the pandemic continues, energy bills can rise significantly.

Martin said wholesale gas prices have gone up 30% since November which means the cheapest energy deals have gone up by £50 a year, too.

He urged people to "check now" if they're on the best possible tariff and potentially see themselves £200 better off.

The money whizz advised that even if prices drop in future, the worst case scenario is that you will pay the small exit penalty to switch again.

He said: "It's better to be safe and pay less now."

The MSE founder explained over half of UK homes are on a big energy firm's standard tariff.

For those who are on such a tariff, the price of energy is governed by the energy price cap which moves every six months, with the next change being on April 1.

The cap will be based on wholesale prices in the six months preceding January 31.

Analysts at Cornwall Insight predict the price cap will rise by a whopping £87 per year on typical use, yet comparisons have to show savings against the current rate which Martin said "in reality, is likely a huge underestimate right now."

If you switch to a new provider, you could see yourself saving hundreds of pounds per year.
