How much is the average gas and electricity bill per month?

Published on:

Last updated:

Calculating the average gas and electricity bill across the UK is difficult as it depends on a variety of factors. The cost of your own bill will depend on the type of property you live in, where you live, the heating system that you have, the energy efficiency of the property, the number of people living there, and your personal usage.

What’s the average gas bill per month?

The average annual gas bill for 2021 (Opens in a new window) was £575, or £47.92 each month based on government statistics from an annual use of 13,600 kWh/year. 

That’s an increase of 3.2% last year compared to the prices for 2020.

What’s the average electricity bill per month?

The average electricity bill per year for 2021 (Opens in a new window) was £764, based on annual consumption of 3,600 kWh/year. That’s £64 per month, an increase of 7.5% on 2020. 

In total that brings the combined average gas and electricity bill to £1339 per year. 

However, energy prices have increased since these numbers were collected last year. On 1 April 2022 increased by almost £700. This means that Direct Debit customers paying default tariffs saw their annual bills rise from £1,277 to £1,971 per year (based on average usage). The price cap is predicted to rise again this October. You can contact your supplier if you're going to struggle with payments.

Your bill could be lower or higher than this amount, even if you’re paying the price cap at the moment, as it will depend on your individual usage.

Why are energy bills so high right now?

Households are facing a steep increase in their energy prices this year due to supply and demand on the global wholesale market.

This demand has driven up the amount providers pay for gas and electricity - and that cost is now being passed onto the consumer.

The energy price cap only affects you if you live in England, Wales or Scotland. 

In Northern Ireland, energy prices are governed by the Utility Regulator. You can find out more about the help available with paying your energy bills (Opens in a new window) on the Consumer Council website. 

What makes up my energy bills?

Your gas and electricity bills are not just the cost of the energy you have used. In fact, your energy bill is made up of lots of different costs.

The wholesale price of the gas and electricity (the amount it costs your energy supplier to buy it) makes up just over a third of your energy bill.

Networking, or the amount it costs to use and maintain the pipes and wires used to get the gas and electricity to your home, accounts for just over a quarter of your bill.

Operating costs, which are the expenses the energy company has to cover, also make up a proportion of your bill. 

Energy companies are also included in a number of government-backed programmes to save energy and reduce emissions. The cost of these is passed on to users and adds a percentage to energy bills.

VAT (Value Added Tax), profit margins and other costs make up the remainder of your energy bill.

How can I use less gas and electricity?

Now you know the average gas and electricity bill across the UK and what makes up your bill, you might be thinking about how you can save energy and cut your bills.

Luckily there are a lot of ways to do this without even switching supplier.

If you want to save on your energy bills, you can start by being sensible about using your heating and lights.

Insulation is also very important, helping to keep homes warm in the winter and cool in the summer. If you don’t have decent insulation or double glazing, then you’re obviously going to have to spend some money to save. 

If you are thinking of selling your home, you may wish to improve your EPC certificate rating.  This may help you sell your home more quickly and may increase its overall value. 

Energy Saving Trust have a guide to Energy Performance Certificates (EPCs)(Opens in a new window)which has with useful tips on how to make improvements to keeping your home warm and save you money. 

Making sure you unplug phone chargers, not leaving things on standby and using energy efficient light bulbs will also help reduce your bills.

How can I spend less on gas and electricity?

Unusually, at the moment you won’t save money by switching suppliers. Once any fixed rate has ended, you’ll be moved onto your energy company’s standard variable tariff. This tariff is cheaper than any fixed rate being offered currently. 

I am struggling to pay my energy bills – what can I do?

It can be very stressful if you are struggling with your energy bills.  You may be worried about getting into debt and unsure how you will manage to afford to heat or power your home. 

Continuing to pay your bills is important, so get in touch with your supplier before you miss a payment or get into debt.  There are lots of ways that your supplier can help including working out a payment plan that works for you.
