Gas, electricity, water, internet and other utilities are important services and basic amenities that ensure you’re able to live a comfortable life. While not all utilities are essential, they do contribute to a good standard of living and most people wouldn’t be without them. Comparing utility bills and comparing energy deals can help you to find the best possible price for these important services.

Last update: February 2021

Prices can vary significantly between suppliers, so it’s important to ensure that you shop around before signing on the dotted line. To show you just how easy it is to compare utilities prices and bills – and to see how much you could save by switching – we’re taking a closer look at utilities and how to get the most for your money.

List of utilities

Before you begin comparing utility bills, it’s important to understand exactly what’s meant by utilities. While the exact services that are considered utilities can vary, in most cases, a list of utilities will look something like this:

  • Gas
  • Electricity
  • Water
  • Internet
  • Phone services

Of these, the most important utilities are gas, electricity and water. However, as gas and electricity are significantly more expensive than water, these are the two utilities that will probably make up the majority of your essential household payments.

Average utility bills in the UK

Some utilities, like internet and phone services, cost the same no matter how many people are using them. However the cost of others, like gas, electricity and water, increases as consumption goes up.
The table below shows how the price of average gas and electricity bills has changed over the past 10 years and the average amount that UK households currently spend on energy.

Fuel 2009 2014 2019
Gas £582 £752 £663
Electricity £488 £592 £713
Total £1070 £1344 £1376

As the table shows, gas and electricity bills have gone up significantly over the past 10 years. This is true even though the total amount of energy we’re using as a country is actually falling.
There are a number of different reasons for this. One of the main factors is the price of wholesale fuel. Thanks to dwindling resources, energy suppliers are having to pay more for their gas and electricity. These price hikes are inevitably passed on to the end user.
Networking costs, which make up around a quarter of your bill, have also increased. These are the costs involved in building, maintaining and operating the gas pipes and electricity wires that distribute energy around the country.
Suppliers have also seen their operating costs increase over recent years. They’re spending more on marketing, sales, customer service and all other aspects of running a retail energy business. Like networking costs, these are also passed onto the consumer.
Last but definitely not least, taxes, charges and environmental levies make up a big part of your energy bill. All gas and electricity has Value Added Tax (VAT) added to it by the government. This is set at 5% and is the same across all supplier
If you live alone or with just one other person, or if your home is well insulated, your annual energy bill could be much lower than the national average. However, if you have a busy household and a property with single glazing, poorly fitting doors and no insulation, you could end up spending a lot more.
The average costs of other household utilities are:

  • Water – £415 per year
  • Internet – £363 per year
  • Line rental (required for phone and broadband connection) – £240 per year

That means that, in total, UK households are looking at spending an average of £2,394 on household utility bills.

Which energy supplier should I choose?

If you feel like you’re currently paying too much for your gas and electricity, you may find you can save money by switching supplier. This is because different suppliers have different rates with some considerably cheaper than others.
To give you an idea of just how much you could save, the most expensive standard variable tariffs cost customers an estimated £1,042 per year. However, the cheapest suppliers charge just £873 per year for the same services. That’s a difference of £169 per year.
Ofgem, the energy industry regulator, has capped average energy costs at £1,042. That means a typical household shouldn’t spend any more than this on their average gas and electricity supply. However, if you have a big house, a big family or a poorly insulated property, you may still find your annual payments exceed the cap.
Although a lot of energy companies price their tariffs in order to meet the Ofgem price cap, there are a growing number that work to offer their customers cheaper deals. These companies often place a real emphasis on affordability and offer a good choice of low cost tariffs.
However, for a lot of customers, price isn’t everything. While most people want a good deal on their utility bills, a lot also want to enjoy good quality customer service, easy access to digital tools, accurate billing and a hassle-free connection. This is why it’s not always a good idea to choose an energy supplier based solely on costs.
Here are a few things to consider before choosing your energy supplier:

  • Price
  • Length of contract
  • Access to digital tools
  • Average customer review
  • Choice of tariffs
  • Fuel mix – how green is their energy?
  • Customer service

You’ll be able to find information about a supplier’s customer service and customer score online. You should also be able to find impartial customer reviews on sites like TrustPilot. Taking the time to properly research a supplier, and read through reviews, should make it easier to find the right energy company for your household.

Comparing utility bills to find the best deal

If price really is the most important thing to you, you can start your search by comparing the cost of various energy tariffs. The easiest way to do this is by using an impartial comparison service. This will save you a lot of time and hassle and allow you to compare a number of different utility bill options at once.
When looking at available tariffs, you’ll see that there are two main options available: fixed rate and standard variable rate deals. If you choose a fixed rate deal, you’ll pay the same amount for each unit of gas or electricity you use throughout your fixed period. If you choose a standard variable rate, the amount you pay will fluctuate in response to changing wholesale energy prices.
In general, fixed rate tariffs are cheaper than standard variable rate deals. You’ll say an average of 10% by choosing a fixed rate deal. It’s important to renew your fixed rate tariff when your initial contract period expires. Most energy companies automatically move customers onto standard variable rate tariffs when their fixed rate deals end. It’s estimated around 54% of consumers are on a default variable rate deal, meaning that they could be paying over the odds for their energy.
If you have a prepayment meter, Economy 7 meter or require another type of specialist service, you’ll need to compare these specific deals before choosing your supplier.
