Energy prices are at record levels. So we put our heads together to come up with some simple steps to help trim your bills.

Key takeaways

  • To reduce energy bills use energy-efficient gadgets and appliances (e.g., A+++ rated), and turn off devices when not in use

  • Upgrade to efficient appliances like smart thermostats and programme your heating to match your schedule

  • Contact your supplier if energy-saving measures aren’t enough. Options like prepayment meters can help manage bills

  • It's always worth running an energy price comparison to see if you could switch to a cheaper deal and lower your bills

How to save energy

The energy saving tips below give you some tools and tactics that will help you save gas and electricity at home.

We recommend comparing energy prices first to check if you're paying more than you need for gas and electricity.

To compare quotes, simply run an energy comparison.

We've included estimated figures from the Energy Saving Trust to illustrate the potential energy savings that you could make.

Boiler and heating tips

Turn down your thermostat by one degree

It's a simple change, but lowering your thermostat by just one degree can reduce your heating bills significantly, potentially saving up to £80 a year.

Considering that heating and hot water account for nearly half of your energy bills, this small adjustment can make a big difference.

Upgrade older or inefficient boilers

Considering a new boiler? You can save energy by upgrading your old boiler to a new A-rated condensing boiler with a programmer, room thermostat, and thermostatic radiator controls.

For a detached house, moving from a G-rated to an A-rated boiler could save around £260 per year - according to a study of boiler efficiency from the Energy Saving Trust.

Adjust your combi-boiler's flow temperature

Set the flow temperature between 60ºC and 70ºC for effective heating in winter, and lower it to 50ºC to 55ºC in milder weather.

If you have a hot water cylinder, invest in an insulating 'jacket'

Stop your water cylinder from cooling down and re-heating by insulating it with a 'jacket.'

If you already have one, upgrade it if it's not at least 80mm thick.

If your radiators have cold patches, bleed them

Bleed your radiators regularly to prevent air being trapped inside.

Trapped air creates cold spots and makes your heating system less efficient - costing you more to heat your home.

If your radiators are making gurgling sounds, taking longer to heat up, or you can feel cold patches near the top - it's time to bleed them.

WarmZilla's guidance on how to bleed a radiator is a great place to start if you've never done this before.

Get your boiler serviced to ensure it's running optimally

You should get your boiler serviced every 12 months, and many boiler manufacturers require this to keep your warranty valid.

If you have boiler cover, you can usually get your boiler serviced for free through your policy.

If you don't have boiler cover, we'd recommend comparing boiler cover plans to keep your boiler running well and keep things cheap if anything goes wrong.

Check your boiler pressure

If your boiler pressure is too low it takes more energy to heat your home - according to WarmZilla, the ideal range for most boilers is between 1 and 1.5 bar. Any lower, and you should repressurise.

Appliance tips

Turn off standby appliances

By simply turning off appliances at the plug, you could save around £40 a year. Smart plugs or timer plugs can help manage this automatically, ensuring you're not wasting electricity on devices that aren't in use.

Install a smart thermostat

Smart thermostats can make your heating more efficient by only warming the rooms you are using. They can also be controlled remotely via your phone, which means you can adjust your home's temperature from anywhere.

Buy energy efficient appliances

When it's time to replace old appliances, choosing those with high energy-efficiency ratings is key. For instance, an A+++ rated washing machine can save you money over time when compared to a less efficient model.

Wash clothes at a lower temperature

Simply washing your clothes at 30 degrees instead of 40 degrees can lead to energy savings.

And if you combine it with cutting down on one wash cycle per week, you could save £22 over the course of a year.

Use the tumble dryer sparingly

Tumble dryers are very expensive to run. So if you can avoid using one, so much the better.

What's more, if you skip the tumble dryer in the spring and summers and rely on clothes worse and warmer ambient temperatures instead, you can save up to £45 per year.

Instead, use a dehumidifier to dry your clothes faster.

Get a smart meter to monitor your usage

Being aware of your energy consumption is the first step towards making informed changes.

Installing a Smart Meter lets you track your consumption with accurate and real-time information. Learn more about how they work with our guide to Smart Meters.

Adjust your fridge and freezer settings

The Food Standards Agency recommends keeping fridges at 5°C and freezers at -18°C. Anything colder than this is a waste of energy and money.

Most modern fridges and freezers have temperature gauges that you can adjust yourself, but if you have older appliances with a numbered dial, you can buy a fridge thermometer to check and refine your temperature settings.

Energy efficient home improvements

Invest in double glazing

Double glazing not only reduces your heating bills, it also helps to cut down on noise from outside.

If you replace single glazing with A++ rated double glazing in a semi-detached home, you could save up to £140 annually.

Draught-proof your property

Draught-proofing your home is a cost-effective way to save heat and money, potentially reducing your heating bills by up to £70 a year.

Simple measures like sealing cracks and using plastic linings for windows can make a big difference.

Check your roof insulation

Heat rises, and without proper insulation, it can escape through your roof. While insulating your loft can cost several hundreds of pounds upfront,

It's estimated that adding 270mm of insulation to an uninsulated home can also shave around £340 off your energy bills each year if you live in a detached house.

Invest in cavity wall insulation

Cavity wall insulation is a thermal barrier that fills the gap between two brick walls in a house, preventing heat loss.

Not all homes are suitable for cavity wall insulation, especially those with narrow cavities, poor brickwork, or exposure to damp.

Cavity wall insulation costs around £4,600 for a detached house and £2,700 for a semi-detached. But can substantially cut your energy bills over time

If your home is suitable, install solar panels

Solar panels are devices that capture energy from the sun and convert it into electricity. Also called photovoltaics (PV), they can be installed on a property’s roof or in the garden.

The average domestic solar panel system costs around £7,000, including installation costs, according to the Energy Saving Trust.

A typical solar panel system can save you around 50-70% on your electricity bills.

Plus, you can actually make money from your solar panels. When your panels generate more electricity than your household can use, this excess electricity can be exported to the grid to be used by others.

How much energy does the average household use?

These figures are examples of annual energy usage in the average household. Your bill may be higher or lower depending on your energy consumption. Bear in mind, too, that your bill also includes standing charges.

Energy usage

Gas (kWh per year)

Electricity (kWh per year)

Low (1-2 people)

7,500 kWh

1,800 kWh

Medium (2-3 people)

11,500 kWh

2,700 kWh

High (4-5 people)

17,000 kWh

4,100 kWh

Compare energy quotes

In the current energy market, switching providers to save money might not always be possible. However, under normal circumstances, comparing energy quotes can lead to savings on electricity and gas.

The process involves providing personal and supplier details, and MoneySuperMarket offers a platform to compare costs, savings, and early leaving fees. Understanding the difference between fixed and variable rates is crucial, and when you decide to switch, the new supplier will handle the process without interrupting your supply.

Winter Fuel Payments are changing, but you may still be eligible

Under reforms spearheaded by Chancellor Rachel Reeves, the Winter Fuel Payment is no longer paid to all Britons of state-pension age. But you can still get it if:

  • You were born before the 23rd of September 1958

  • You live in England, Wales, or Northern Ireland

  • You're in receipt of certain benefits, such as Pension Credit, Universal Credit, or Income Support.

Not sure if you qualify? Read our writeup on the recent changes to the Winter Fuel Payment.

If you're on low income, you may qualify for social tariffs

If you're on a low income or claiming certain benefits, you may qualify for social tariffs from your energy provider.

Cold Weather Payments are available if you're claiming certain benefits

If you're claiming certain benefits, including Universal Credit, you may qualify for the Cold Weather Payment - an extra payment of cash for each week of cold weather in the winter.

Look into the Warm Home Discount

The Warm Home Discount gives vulnerable and low-income households a one-off payment to help with energy bills in the winter.

If you live in Scotland, you may qualify for the Winter Heating Payment

The Winter Heating Payment (WHP) is available for those in receipt of certain benefits, like income support and pension credits.

The WHP is not based on temperature and is paid regardless of the weather.

Other forms of energy-related social security the Scottish government provide are:

  • Child Winter Heating Payments

  • Pension Age Winter Heating Payments (replacing the Winter Fuel Payment)
