High electricity and gas bills - how you can reduce them

Find out how to reduce high electricity and gas bills with these easy steps

Why is my electricity or gas bill so high?

There is a number of reasons as to why your energy bill is higher than you expected. These could include the bill being based on an estimated rather than actual energy use, inadequate insulation, a cold spell, having just moved to a new home and lots more. Here we take you through the main causes of high energy bills and what you can do to avoid them in the future and how we can help you now if you're struggling to pay your bill.

Find out the main reasons your bill can increase

Is my energy bill accurate?

If your bill’s based on estimated reading it might not accurately reflect your energy use. So first of all, check to see if your bill has been estimated.

If the answer’s yes, check your meter. If you can see a lower number than the figure on your bill, get in touch with your supplier. With a more accurate reading, they may well re-issue (and possibly reduce) your bill.

If your energy use has dropped because of an unseasonably warm spell or if you’ve moved into a new property, an estimated bill might not reflect your energy use accurately.

Am I on the right tariff?

It may surprise you to learn that a lot of UK homes overpay on their energy bills simply because they aren’t on a competitive tariff.

Unfortunately at the moment due to the energy crisis, it is difficult to find a competitive deal anywhere.

Have I used more energy this winter?

If you're of pensionable age, disabled, have severe health problems or are on a low income, you may be entitled to extra help during the winter. We've listed the other government schemes and benefits below.

In 2022 the government also introduced additional cost of living support if you're eligible. Find out more

How to save energy in the summer

During the warmer summer months we naturally use less electricity – we keep the heating off, showers cool and don't need the lights on for as long. However, there are still ways you can reduce your electricity bill and save even more in summer. Find out some of our top tips for saving energy during the summer

Is my home properly insulated?

One of the most common reasons for high energy bills is poor insulation. The better your insulation, the more value you get for every unit of heat you use. Read more about insulating your home properly, guiding you through the various types of insulation available and the government subsidies available to help with your insulation costs.

We're working with trusted suppliers to get homes across Britain properly insulated. Even if you're home is insulated it may not be up to the current standard.

Here are the savings insulation can save you on your bills each year:

  • Cavity wall and loft insulation together can save you up to £995 per year on bills(4)
  • Solid wall insulation installed can save you up to £710 per year on bills(5)

Am I heating my home efficiently?

Natural gas is by far the most popular heating fuel in the UK and when used with a modern condensing boiler, one of the most affordable. Read our blog on gas vs electric heating.

Is my heating system programmed properly?

According to the Energy Saving Trust, turning down your thermostat by just one degree can result in a saving to the average household of up to £90 per year. In addition to this simple change, you can also take control of the timing and zoning of your heating. Your rooms don’t need to be heated if you’re not using them so if you’re asleep, out of the house, or not using certain rooms, you can save money by switching off your heating.

Is a new gadget or appliance adding to my bill?

A new appliance like a heater or tumble drier can bump up your energy bill but our love of gadgets will also have an effect. The graph below shows that while some items like cookers and washing machines have become more energy efficient over the years, ‘consumer’ electronics such as game consoles, home computers etc. are a growing part of our energy use.
