What’s the average UK energy bill?

Whether it’s to lower your energy bills or to reduce your carbon footprint, most of us are thinking about how we can make greener choices at home. 

Energy use and how much carbon a home emits are measured in each property’s Energy Performance Certificate, ranked in bandings from A to G. 

How much are energy bills right now? 

Well, our latest analysis of properties that have recently been listed for sale and to rent shows that the greener a home is, the lower the average annual energy bill will be. The average monthly energy bill for a 3-bed semi-detached house with energy efficiency rating D is around £193, or £2,311 annually. 

Take a look at our energy bill tracker to see what you might pay annually, based on your EPC rating and property type:

Rightmove’s annual energy bill tracker

Average energy bill calculations are based on energy consumption data from the EPCs of all homes for sale on Rightmove in August 2024, combined with the latest energy meter data, factoring in the latest energy price cap for October – December 2024.

Where can I check the average energy bill for a property?

Within a home’s Energy Performance Certificate, you’ll find an estimated annual bill for heating, lighting and hot water. It’s a calculation based on the property’s condition at the time of the assessment. So, for example, if older single-glazed windows have been replaced with new double glazing since the certificate was created, this wouldn’t be factored in until a new certificate was produced. 

You’ll usually find a list of recommended home improvements within the certificate, too. Including how many points they’d likely add to your energy–efficiency score, as well as how much you could expect to save on your bills.  

How much energy a household uses will vary based on lifestyle, the number of people living there, and how energy efficient your property is to begin with.   

Why do homes with higher EPC ratings have lower average energy bills?

A greener home is one that is more energy efficient to run, which means it uses less energy to perform the same task as a more inefficient home. 

Homes with lower energy-efficiency ratings will require much more power to keep them warm, and well lit. Which is why they have higher energy bills, and higher carbon emissions, on average. 

Many homes in the UK were built decades or even hundreds of years ago with older materials and technology, which is why the average UK rating is a D. 

Making changes that make your home greener can not only save you money on bills, they also help to reduce the amount of carbon dioxide that a home emits. 

Right now, Office for National Statistics (ONS) figures show that around a quarter (26%) of UK greenhouse gas emissions come from our homes. 

How can I save money on my energy bills?​

There are lots of small things you can do to help reduce your energy usage at home. And, doing them all at once can result in a significant reduction in your energy bills. There are changes you can make that come with no or low costs, that could make a noticeable difference in the long term.   

These include things like adjusting your combi-boiler flow temperature, closing curtains and blinds, or applying for a smart meter, if you don’t have one already.  Take a closer look at 10 mistakes that could be adding £100s to your energy bill.

And there are other energy-saving improvements to consider, too. Such as looking into getting a smart thermostat, or checking whether your home could benefit from improved insulation.  

You might be wondering whether you could reduce your bills by switching to a different energy supplier, or locking in a better deal with your existing supplier. Our calculator will show you energy quotes bespoke to your household, including how much you could save.

How can I make my home more energy efficient?​

If you’re looking at making bigger changes to make your home greener, you might be considering retrofitting your home, which includes changes like adding solar panels, triple glazing, insulation, or converting to a heat pump. These changes are often the suggested improvements you’ll find on an energy performance certificate, so investing in them could also raise your home’s energy rating.   

While costs continue to be a barrier to households making these changes, the initial costs can be outweighed by the long-term benefits, which include:   

A lower carbon footprint:  

• Decarbonsing your home’s heat source, or reducing its reliance on fossil fuel heating, will reduce your home’s emissions    

Reduced energy usage:

• Our energy-saving guides detail the cost of making changes, and the savings you can expect to see on your bills 

A ‘green premium’ that could increase your home’s value:

• Our analysis shows that sellers who’ve improved their EPC rating from F up to a C could see an average house price increase of almost £56,000, on top of local house price growth (Rightmove Greener Homes Report 2023).

There are grants and schemes in place such as the Great British Insulation Scheme, and the Boiler Upgrade Scheme, which can help with a portion of the cost of green improvements.    

Where could happen to bills in the future?

For the period October to December 2024, the price cap has increased to £1,717. This is £149 higher (+10%) than the previous quarter’s price cap which was in place from July to September.

According to Cornwall Insights – an organisation that predicts what will happen to energy bills – energy prices could rise again under the January 2025 price cap. The next price cap update is due to be announced in November.

However, future price cap forecasts could change. This is because the price of wholesale gas can be affected by global events, which in turn impact the energy market.

Frequently Asked Questions: Your questions about energy usage and costs answered

What does a unit of energy cost right now?

The wholesale price of gas can go up and down, which means the underlying costs energy suppliers need to cover can change. So, to prevent companies from passing on large price rises to consumers – particularly the kind of hikes we’ve seen in recent years – the energy price cap is in place. The cap is set by energy regulator Ofgem: an independent organisation that works to ensure energy customers are treated fairly.   

The price cap amount takes into account any increases in wholesale prices, but does so in a proportionate way. The figures in the table below shows the maximum amount energy companies are able to charge customers, per unit, for the length of time the price cap is in place.

What’s the energy price cap and how will it affect what I pay?

The energy price cap was set up in 2019, to limit the effects of rising energy costs on households. From October to December 2024, the price cap has increased by 10% compared by the previous quarter, adding an extra £149 to household energy bills on average.

The regulator Ofgem sets the price cap, and it’s reviewed every three months.

The dates of upcoming price cap announcements, and the periods the updated price cap will cover are:

• 1 January to 31 March 2025, announced by 25 November 2024
• 1 April to 30 June 2025 announced by 25 February 2025
• 1 July to 30 September 2025, announced by 26 May 2025

How much power does a typical household use

Ofgem has outlined how much power you might expect to use based on the size of your property, and the number of people living in it.  

Energy is calculated in kilowatt hours, often called ‘units’, and it’s estimated that a typical household in England, Scotland and Wales will use around 2,700 kwh of electricity and 11,500 kWh of gas each year. Right now, gas is significantly cheaper than electricity per unit. Typically, gas will account for around 80% of a home’s energy usage, largely due to households’ current reliance on gas boilers.
