Keep reading to find out how some changes can save you more than £300 a year.
1. Switch energy supplier
If you haven't switched your energy supplier or tariff recently, there’s a good chance you could save a lot of money. That’s because you will probably be paying out-of-contract rates. These are often the pricier deals on the market, even though they're price capped.
Out-of-contract rates, also called standard or default tariffs, are the automatic rates for customers who have not chosen their energy tariff or who took no action when their fixed deal expired.
Our research reveals that you could save around £200 in a year by switching from a standard or default tariff set at the level of the price cap to the cheapest available deal. How much gas and electricity your home uses will partly determine how much you can save.
11 million households are on a standard or default tariff, according to energy regulator Ofgem, meaning there are likely big savings you could make on your energy bill.iklan
How often should I switch energy tariff?
If you let a fixed tariff run out, you'll end up on a standard variable tariff, and you could end up paying hundreds of pounds a year more than you should on your energy bills.
Most fixed tariffs last a year so, to avoid overpaying, switch once a year to a cheaper deal, timing the switch to coincide with your contract ending.
Unless a particularly enticing deal comes along you don't need to worry about switching more often than this.
We've crunched the numbers and found that, over a two year period from September 2018, switching twice or even four times a year wouldn't have saved a medium energy user more than switching just once a year. Some suppliers charge exit fees for switching mid-contract, which would eat into your savings, and it's more hassle.
There may be exceptions to this rule if energy prices drop dramatically a few months after you've switched; it could be worth checking a price comparison site if you see in the news that energy prices are at record lows mid-way through your contract.
2. Install and use heating controls
If you don’t already have a room thermostat, programmer and thermostatic radiator valves, installing them – and using them well – could save a typical home £70 a year according to the Energy Saving Trust. It will also cut your home’s carbon emissions by 305kg a year.
Heating controls should let you:
- set your heating and hot water to turn on and off to suit you
- heat only the parts of your home that need it
- set different temperatures for different areas of your home
- keep your home at a temperature that’s comfortable, without wasting heat.
Reducing room temperatures by just 1ºC can cut heating bills by another £55 a year so put on a jumper before you turn up the heating.
If you only need to heat one room in your house, it may be cheaper to use a portable electric heater and keep the thermostat turned down. For those who live alone or work from home, investing in an electric heater could save on heating bills over time as you're not heating the whole house unnecessarily.
These let you operate your heating remotely via the internet using your mobile phone, tablet or computer. Some also have sophisticated features, such as learning your routine or adjusting settings depending on the weather forecast.
Whether a smart thermostat could save you money will depend on your lifestyle, how efficiently you control your heating already and whether you’d prefer it to using traditional heating controls. Find out whether smart thermostats are worth it.
3. Replace light bulbs
Energy-saving light bulbs can help you to cut your energy bills easily. An LED light bulb costs around £1.71 a year to run . Over its lifetime, it could cut around £180 from your energy bills, compared with an old-style bulb.
Remember, energy-saving light bulbs last longer than traditional ones.
|Type||Lifetime||Annual running cost|
|Halogen||2,000 hours (around 2 years)||£8.42|
||10,000 hours (10 years||£2.04|
||25,000 hours (25 years)||£1.71|
LEDs are the most energy-efficient light bulbs, and use almost 90% less energy than traditional incandescents. LED bulbs can cost less than £3 for one, and some can pay for themselves through energy savings in a few months. To find out more, see our light bulb reviews.
Already use energy-saving bulbs? Remember to switch off lights when you leave the room, and use the best bulb for the size of room or the job it will do.
4. Cut draughts
Stopping heat from escaping through unwanted gaps around doors and windows could help you save around £20 a year in a typical home, according to the Energy Saving Trust. Plus, you could save even more with professional draught-proofing. Take a look at the following areas:
- Windows Use draught-proofing strips around the frame. Brush strips work better for sash windows.
- Doors Use draught-proofing strips for gaps around the edges, and brush or hinged-flap draught excluders on the bottom of doors.
- Chimney and fireplace If you don't use your fireplace, use an inflatable pillow to block the chimney, or fit a cap over the chimney pot. If you have an open chimney, this alone could save you £15 a year.
- Floorboards and skirting Floorboards need to move, so use a flexible silicone-based filler to fill the gaps.
- Loft hatches You can prevent hot air escaping by using draught-proofing foam strips.
Already repaired large draughty areas? Consider smaller holes that let in air, such as keyholes and letterboxes.
5. Choose energy-efficient appliances
If you're replacing an appliance, you can cut your electricity bills by choosing the most energy-efficient model. For example, running costs for washing machines, depending on size, vary between £15 and £63 a year.
The most visual indication of a product’s energy efficiency is its EU energy-efficiency rating. But we test energy consumption in a way that reflects how you actually use different appliances, so we can more accurately tell you which ones use less energy. For example, we test washing machines on the 40°C cottons program most commonly used by Which? members, while the EU Energy Label tests are 60% based on the 60°C cottons program.
In our lab tests, we reveal the annual running costs for every large appliance, from TVs to dishwashers. You can use the results of our tests to find out how much appliances cost to run, and which ones will be the cheapest.
How much money energy-efficient appliances can save you per year
- Washing machine: £48
- Tumble dryer: £96
- Fridge-freezer: £69
Our research shows that swapping power-guzzling kitchen appliances for energy-saving models could save you up to £213 a year.
6. Get a new boiler
More than half of what you spend on energy in a year goes on heating. So replacing an old, inefficient boiler with a modern energy-efficient one makes a big difference to your bill.
If you upgrade an old G-rated gas boiler to a new A-rated condensing model, including a programmer, room thermostat and thermostatic radiator valves, you could trim your fuel bills by as much as £205. That’s based on the latest estimates from the Energy Saving Trust for a semi-detached home. And if you live in a detached home you could save £315 a year.
If you don’t currently have heating controls, installing them at the same time will help you to save even more money.
A condensing boiler is a good choice if you’re looking for efficiency. They capture waste heat released from the flue, and use it to heat water returning from your central heating system.
But a new boiler is expensive, costing between £1,240 and £3,840 when you include installation. Expect to pay at the higher end of the scale if you’re replacing a conventional heat-only boiler with a condensing combi boiler. So if saving money is your priority, it’s probably not worth replacing your boiler until it’s beyond repair.

7. Home insulation
Insulating both your loft and cavity walls can save you up to £315 a year.
Laying loft insulation to a thickness of 270mm in a typical non-insulated three-bedroom semi could trim £150 a year from energy bills, as less heat will be lost through the roof.
Insulating cavity walls can save up to £165 a year in a semi-detached house. Solid-wall insulation, although more expensive to fit, could save you £225 in the same type of house.
Already installed loft insulation? Even if you already have some loft insulation, you could save an extra £14 a year by topping it up from 120mm to the recommended 270mm.
8. Quick energy-saving tips
If you’re pushed for time or money, have done everything else on this list or simply want to get started cutting your energy bill straight away, try these tips:
- Understand your energy bill. It’s the first step in knowing how much gas and electricity you’re using, and where you can cut back. A smart meter will tell you how much energy you use in real time, or you can buy an energy monitor.
- Don’t leave your gadgets on standby. This could save you up to £35 a year, according to the Energy Saving Trust.
- Fit a water-efficient showerhead. These keep your shower feeling powerful while cutting down on your hot water use.
- Only run your washing machine and dishwasher when they’re full, and use energy-efficient programs. Dry your washing outside, rather than using your tumble dryer.
- If you live alone, it may be cheaper to use an electric heater for the room you're using, rather than heating the whole house.
9. See if you're eligible for free cash
Money off your electricity bill, money towards installing solar panels or insulation, and grants for buying a new boiler are just some of the schemes currently on offer to help you save money on energy, for less.
10. Keep your energy bill under control
Paying your energy bill through direct debit means you spread your energy costs over the year, and avoid big shock winter bills. Providing your energy supplier with regular meter readings will keep your bill as accurate as possible. This helps to avoid building up a big credit or debit balance.
If you think you've been paying too much and are in credit with your energy supplier, send it meter readings. You can ask for a credit refund at any time, even if it doesn't fit with your energy supplier's automatic refund policy.
Your right to do this is set out in suppliers’ licence conditions. These say that it must refund credit promptly when you ask, unless there are reasonable grounds not to.
It will check whether your payments and credit will cover your predicted use over the next year, and require an up-to-date meter reading to make sure that a refund won’t result in debt or increased payments in future. You’ll typically need to contact customer services or fill in a refund request form online.
Do remember that if it's summer, you should be building up credit for winter. But if you're owed money, don't hold back. Contact your energy supplier and ask for a refund.
