How to Save Money on Your Energy Bills This Winter: UK Tips That Actually Work
Why Winter Energy Bills Hit So Hard in the UK
When the temperature drops, energy bills tend to spike and many UK households feel the strain. With standing charges rising and unit costs still well above pre-2022 levels, finding ways to trim your winter energy usage has never been more important. The good news is that a mix of quick fixes, smart habits, and longer-term changes can make a real difference to your monthly outgoings.
Whether you are renting or own your home, there are practical steps you can take right now to bring those bills down. Here is a comprehensive guide to saving money on your energy bills this winter, with tips that are specifically relevant to UK households.
1. Switch to a Cheaper Energy Tariff
The single biggest action you can take is to check whether you are on the best available tariff. The energy market has shifted significantly, and many people are still sitting on expensive standard variable tariffs when cheaper fixed deals are available.
Use a comparison site like Octopus Energy or Uswitch to see what deals are on offer. Some suppliers offer £50 or more in credit when you switch, which can take the edge off those first big winter bills.
What to look for when switching
- Fixed vs variable: A fixed tariff locks in your unit rate for 12 months, protecting you from mid-winter price hikes.
- Exit fees: Check whether the tariff charges a fee if you leave early. Many do not.
- Green tariffs: Some renewable tariffs are now cheaper than fossil fuel equivalents.
- Refer-a-friend credit: Suppliers like Octopus Energy offer £50 credit for both you and a friend who switches.
2. Turn Your Thermostat Down by One Degree
It sounds almost too simple, but lowering your thermostat by just one degree can cut your heating bill by up to 10%. The ideal temperature for a living room is between 18 and 21 degrees Celsius, and many people have their thermostats set higher than necessary without realising it.
If you are wearing a jumper indoors and still feel warm at 20 degrees, there is no need to push the temperature to 22 or 23. Every degree above 21 adds roughly 10% to your heating costs over the winter months.
3. Use Smart Heating Controls
Smart thermostats and TRVs (thermostatic radiator valves) give you far more control over where and when your heating runs. Instead of heating the whole house to the same temperature all day, you can zone your home and only warm the rooms you are actually using.
Smart controls worth considering
- Smart thermostats like Nest, Hive, or Tado learn your routine and adjust heating automatically.
- Smart TRVs let you set different temperatures for each room from your phone.
- Heating schedules ensure the boiler only fires when needed, not when you are asleep or out.
According to Energy Saving Trust, installing smart heating controls can save a typical household between £75 and £150 per year.
4. Bleed Your Radiators
If your radiators are cold at the top and warm at the bottom, they have trapped air inside and are not working efficiently. Bleeding them is a quick DIY job that costs nothing but a radiator key (about £1 from any hardware shop).
Once bled, your radiators will heat up faster and more evenly, meaning your boiler does not have to work as hard or run as long to reach your target temperature. This is one of the easiest budget home improvements you can do yourself.
5. Draught-Proof Your Home
Draughts are one of the biggest causes of heat loss in UK homes, particularly in older properties. Sealing gaps around doors, windows, chimneys, and floorboards is cheap and surprisingly effective.
Quick draught-proofing wins
- Draught excluder strips around door and window frames cost around £5-£10 per room.
- Chimney balloons or chimney sheep stop warm air escaping up unused fireplaces.
- Letterbox flaps with brushes prevent cold air pouring in through the front door.
- Radiator reflector panels behind external-wall radiators bounce heat back into the room instead of losing it through the wall.
Energy Saving Trust estimates that draught-proofing around windows and doors alone can save around £25-£50 per year, while chimney draught-proofing adds another £20-£30 in savings.
6. Wash Clothes at 30 Degrees
Modern washing powders and detergents are designed to work effectively at 30 degrees Celsius. Dropping from 40 to 30 degrees reduces the energy used per wash by roughly 40%, and most everyday loads will come out just as clean.
If you have a heavily soiled load, use a 30-degree stain setting rather than bumping up to 60. Reserve hot washes for towels and bedding once a month to keep bacteria in check.
7. Stop Using the Tumble Dryer
Tumble dryers are among the most expensive appliances to run in any home. A typical vented dryer costs around £1.50-£2.00 per cycle, and many households run them daily during winter. That adds up to £40-£60 per month.
Instead, use heated airers (which cost around 10-15p per hour to run), hang clothes on indoor drying racks near radiators, or use a dehumidifier in a small closed room to speed up drying. A dehumidifier running for a few hours uses far less electricity than a single tumble dryer cycle.
8. Check If You Qualify for Energy Grants and Schemes
There are several government and supplier-backed schemes that can help with winter energy costs, and many people miss out because they do not know they are eligible.
Schemes to check
- Warm Home Discount: A £150 rebate on your electricity bill if you receive certain benefits or have a low income.
- Winter Fuel Payment: Tax-free payments for people born before a certain date to help with heating costs.
- Energy Company Obligation (ECO4): Free insulation, boiler upgrades, and heating improvements for eligible low-income households.
- Great British Insulation Scheme: Free or discounted cavity wall or loft insulation for homes in lower council tax bands.
Contact your energy supplier or check the GOV.UK website to see which schemes you qualify for. It is also worth asking your supplier directly about any hardship funds or grants they offer, as some have additional support that is not widely advertised.
9. Insulate Your Hot Water Cylinder
If you have a hot water cylinder with an old or thin jacket, fitting a new British Standard insulating jacket (at least 80mm thick) costs around £15-£20 and can save you around £20-£30 per year. The jacket pays for itself within months and keeps your water hotter for longer, reducing how often your boiler needs to reheat.
10. Switch Off Standby and Cut Phantom Load
Many appliances continue drawing power when switched off at the wall but left plugged in. Televisions, games consoles, microwave ovens, and phone chargers are common culprits. This phantom load can add £50-£80 per year to your electricity bill.
Use standby shutdown plugs or smart power strips that cut power automatically when devices go into standby. Alternatively, just get into the habit of switching things off at the wall when not in use.
11. Compare Your Energy Usage With Others
Many energy apps and supplier portals now let you compare your usage against similar homes in your area. If your usage is significantly higher, it could indicate an issue with your heating system, insulation, or an appliance that is drawing more power than it should.
Getting a smart meter installed (free from your supplier) gives you real-time data on your energy use and makes it far easier to spot where savings can be made.
12. Consider Longer-Term Investments
If you own your home and have some budget to invest, longer-term improvements can dramatically reduce your energy bills for decades to come.
- Loft insulation: Topping up to 270mm can save £150-£200 per year.
- Cavity wall insulation: Can save £150-£250 per year for a typical semi-detached home.
- Double or triple glazing: Reduces heat loss through windows by up to 50% compared to single glazing.
- Heat pump: With the Boiler Upgrade Scheme grant of £7,500, an air source heat pump can lower heating bills significantly, especially if you are coming off oil or LPG.
Many of these improvements can be subsidised or fully funded through ECO4 or the Great British Insulation Scheme, so always check eligibility before paying out of pocket.
Small Changes Add Up to Big Savings
You do not need to do everything on this list to see a difference. Even implementing three or four of these tips can cut your winter energy bills by £100-£300 over the season. Start with the free and low-cost changes like bleeding radiators, draught-proofing, and turning the thermostat down, then work towards the bigger investments as budget allows.
