1. Electrical Energy-Saving Tips

Turn electrical appliances off at the mains

Most electrical appliances can be safely turned off at the mains without interrupting their programming, including TVs, games consoles, laptops, computers and small kitchen appliances like kettles and toasters. 
 
To make life easier, smart plugs automatically turn your devices off standby and can be controlled remotely from your mobile. Alternatively, timer plugs turn your appliances on and off depending on the schedule you set.

Avoid watching DVDs on games consoles

Games consoles use more energy than traditional DVD or Blu-Ray players, so why not dig out your old DVD player next time you want to watch a film? Just remember to switch every device off at the mains when it’s not in use. 

Turn the brightness down on your TV

Reduce the brightness on your TV to save energy. Most TVs also have a range of customisable settings, so you can switch off any additional features you don’t need.

Unplug devices once fully charged

Charging your phone overnight might seem like the best option to power your device for the day ahead, but this can waste energy. Instead, keep an eye on your phone as it charges in the evening, then unplug it once it’s full to save energy. 

Unplug devices once fully charged

Have a blackout night and turn off all non-essential appliances

Challenge yourself to a blackout evening once a month, where all non-essential appliances are switched off. Instead of watching TV, gaming or scrolling on your phone, play board games or read a book.

 

If this doesn't sound like your thing, work on getting into a good daily routine. Before you go to bed, go round and turn all your appliances off every day.

Upgrade your lighting

Once your less-efficient fluorescent or halogen bulb stops working, upgrade to LED bulbs for long-lasting, bright, and extremely efficient lighting. Better yet, opt for an LED smart bulb which you can control using your smartphone or tablet. If you're someone who leaves lights on by mistake, this could save lots of energy over a year.

 

New LED bulbs last for 50,000 hours, which is roughly 50 years based on an average use of 1000 hours a year. 

Upgrade your lighting

Simon Oram, Smart Home Category Manager at Toolstation said:

 

“While turning off the lights when you’re leaving the room is a great habit to pick up, it may also be worth switching to LED smart lightbulbs around the home. These can connect to a range of smart home providers such as Alexa, Google Assistant, Apple Siri and more. Smart LED lightbulbs can take the pressure off, so in the event that you forget to flip the switch off on your way out, you can do so from your phone.”

Use rechargeable solar lights at night

Invest in rechargeable LED solar lights that you can charge outside during the day, then bring them inside or move to a dark garden corner to use at night. Although this is harder during the winter, with less sunlight available, try positioning them in a bright spot with no shadows or a sunny window. 

 

Solar lights need no additional wiring which makes them perfect for lighting up dark gardens without cabling and using mains electricity.

Sarah Gale, Lighting Category Manager at Toolstation said:

 

“Solar lighting can be used both indoors and outdoors – so long as they’re charged outside first. Although charging solar lighting is harder during the winter, with less sunlight available, try positioning them in a bright spot with no shadows or a sunny window.

 

“Outdoor lighting may be the first to go when it comes to energy saving as the home is often the priority. However, rechargeable solar lights can be a great addition to your front or back garden both for ambiance and to light garden paths.”

Install motion sensor lights

Switching to motion sensor lights inside and outside your home can help save energy. The motion sensor is activated by movement and works on a timer, so the lights will switch off automatically when you leave the area.

Sweep hard floors instead of vacuuming

Avoid switching on the vacuum cleaner and use a broom to sweep any hard floors in your home, including wood, vinyl and tiles. Sweeping doesn’t take any longer than vacuuming and saves energy. 

Dust lightbulbs and radiators often

Dusty lightbulbs and radiators can reduce their efficiency, so keeping them clean is essential. Removing dust can make your home brighter and warmer while improving air quality.

Keep your fridge two-thirds full

A well-stocked fridge stays cooler than an empty one, so keep it at least two-thirds full if possible. Less space for air to circulate means less energy is needed to maintain the temperature.

Clean your refrigerator coils

To keep your fridge working efficiently and save energy, you should regularly clean the condenser coils at the back of the appliance. Condenser coils can quickly accumulate dust and debris, meaning they can’t release heat and cool the system efficiently, which uses more energy.      

 

Consult the instruction manual for your fridge if you're not sure.

Remove limescale from your kettle

Limescale build-up inside your kettle can make it less efficient, as it acts like an insulator around the kettle’s heating element.  This means more energy is required to heat the water. De-scaling your kettle often ensures it’s working well and can prolong its life.

Regularly defrost your freezer

Excess ice inside your freezer makes it less efficient. Ice acts like an insulator, making the freezer’s motor work harder to cool the air inside, so defrost it regularly to save energy. 

Open a window when cooking

Instead of switching on your kitchen extractor fan, open a window while cooking to save energy.

Keep your freezer full

Like refrigerators, freezers also work more efficiently when full, as less energy is needed to cool the air inside. 

Set your fridge and freezer temperatures correctly

The optimal temperature for your fridge is 5˚C and -18˚C for your freezer. Setting the temperature lower than this will waste energy and makes little difference to your food’s freshness. 

Clean your oven

Regular cleaning can make your oven more energy efficient by helping it reach the desired temperature faster and allowing more even heat distribution. 

2. Food & drink energy-saving tips

Only boil the water you need

When boiling the kettle, only fill it with as much water as you need. Heating excess water wastes energy, so if this isn’t already a habit in your household, it’s one of the most effortless changes you can make. 

 

Alternatively, boil a whole kettle in the morning and save the rest in an insulating flask to use throughout the day.

Only boil the water you need

Put lids on pans when cooking

Putting a lid on your pan helps retain heat, enabling you to cook at lower temperatures, reduce cooking time and save energy. 

Use microwaves and air fryers instead of the oven

Many foods are suitable for cooking in the microwave, which uses much less energy than an oven. Microwaves only heat the food itself rather than the air around it, and air fryers save energy because they're smaller and aren't heating much empty space. Not only will this save money, but it can also be quicker to cook certain foods in a microwave or air fryer. If you already have one, it might be time to use it more! 

Use microwaves and air fryers instead of the oven

Batch cook meals

Meal prep for the week ahead to save time and energy. You’ll only have to turn on the oven or hob once to cook everything, then reheat each portion in the microwave. 

Boil pasta for two minutes, then let it sit to finish cooking

Instead of boiling your pasta on high heat for the time specified on the packaging, try cooking it for just two minutes, then leave it to rest with a lid on for ten minutes. Although it may take a little longer, this method saves energy.

3. Heating energy-saving tips

Bleed radiators regularly

Does your home take a while to warm up after turning on the heating? Are your radiators cold at the top and warm at the bottom? They may need bleeding. Plus, they’ll use less energy to heat your home, saving money on bills. 

 

Use a radiator key or slotted screwdriver (depending on your radiator type) to let trapped air out of your radiators.

Bleed radiators regularly

Danielle Robinson, Central Heating Category Manager at Toolstation:

 

“Firstly, you’ll want to check that your heating is turned off so that the radiators aren’t too hot to touch. Next, you’ll need to locate the radiator bleed valve – usually found on the top corner of the radiator, they look like a round hole with a square inside. Once located, open the valve to release the air, then insert the radiator key and slowly turn it anti-clockwise for around a quarter turn. As the air escapes, you should hear a hissing sound that will stop once the radiator has been fully bled. To finish, close the valve and then check your radiator function by switching on your central heating and hot water and waiting for your radiators to heat up.”

 

Take a look at our guide on How To Bleed A Radiator for more information.

Service your boiler regularly

Ensure your boiler is working efficiently with regular servicing carried out by a gas safe engineer. Services identify problems like limescale deposits and leaks before they worsen or become costly to repair, helping to prevent heat loss and saving you money in the long run.

Danielle Robinson, Central Heating Category Manager at Toolstation: said:

 

“It may seem like another expense but it’s recommended to have your boiler serviced by a professional at least once a year – and ideally ahead of winter. Small problems, can quickly become big problems and so it’s best to get any potential boiler issues identified as soon as possible.”

 

“A boiler service can check that your boiler is working as efficiently as possible as well as check for any water or gas leaks.” 

Clean and protect your central heating system

Corrosion can cause build ups of sludge, limescale and debris in your central heating system, which can cause cold spots in your radiators and make it harder to heat up your home. Central heating additives flush out your pipes and radiators to keep them working at maximum efficiency, while inhibitors and protectors prevent bacteria, sludge and limescale build up. 

Clean and protect your central heating system

Danielle Robinson, Central Heating Category Manager at Toolstation said:

 

“An efficient central heating system is imperative for winters in the UK – and if they go wrong, they can be costly to fix. That’s why it’s important to make sure you’re doing all you can to help maintain your central heating system.” 

 

“It’s recommended to regularly use central heating cleaners to remove any rust or limescale that could be building up. This can boost the efficiency and longevity of your central heating system which will save you money in the long term. You can also use boiler silencer fluid after cleaning to reduce any boiler noise. If your boiler is leaking or regularly losing pressure, you may also benefit from using a central heating leak sealer to address the problem.”

Buy thermal curtains

Thermal curtains will help keep heat inside your home. Instead of buying new curtains, you could sew a thermal lining into your drapes.

Invest in an electric blanket

Electric blankets can be cheaper to run than central heating, as you’ll only need to switch them on for a short amount of time to feel warm. Plus, they provide direct heat to a small area around you rather than heating an entire room. 

Choose a high tog duvet

Invest in a high tog duvet for the winter to stay warm and save money on heating overnight.

Fill gaps between floorboards

If you have exposed wooden floorboards, fill in any gaps with specialist wood filler or putty to prevent heat loss. 

Keep your hot water cylinder toasty

If you have a heat-only or system boiler, you’ll have a hot water cylinder somewhere in your home – probably in an upstairs airing cupboard. Water is heated periodically throughout the day and stored in the tank ready for use. A cylinder jacket can reduce your energy usage by keeping the hot water cylinder warmer for longer.

Keep your hot water cylinder toasty

Danielle Robinson, Central Heating Category Manager at Toolstation said:

 

“Insulating your hot water cylinder is a quick and easy way to ensure that the water you’ve heated stays hot. If you already have a jacket installed, it may be worth checking the thickness and if necessary, replacing it with a new one. Energy Saving Trust recommends that hot water cylinder jackets should be at least 80mm thick for optimum performance.”

Purchase a chimney balloon

Chimney balloons or chimney sheep seal the flue to stop heat from being lost. Use them when the fireplace isn’t lit, or if you have a disused chimney, they can be installed permanently. 

Paint the outside of your house a dark colour

Have you ever thought about why islands like Santorini are dotted with white houses? White reflects heat away, which keeps homes cooler in scorching Greek summers. 

 

Black absorbs heat from the sun, so if you're considering repainting your home any time soon then a dark paint will help keep more of the heat from the sun inside in the winter. Colours like dark grey, navy blue or black can add to your home’s aesthetic appeal while offering a practical energy-saving solution. 

Install radiator reflectors

Radiator reflectors prevent heat from being lost through the walls. They are a sheet of reflective insulating foil that’s installed behind the radiator panel to reflect heat back into the room, keeping your home warm and saving energy. 

Install radiator reflectors

Tiffany Hall, Insulation Category Manager at Toolstation said:

 

“At a relatively low cost, foil insulation can be installed behind your radiator to ensure heat is kept in your home by reducing what is lost through the walls. Well-fitted radiator reflector foil could help to reduce the amount of energy needed to heat your home and could also help to keep the room warmer for longer once the heating is switched off.”

Use space heaters

Heat small spaces efficiently with a space heater. For example, if you don’t want to switch on the central heating when working at home, invest in an electric heater for your home office.

 

If you want to heat your entire home, central heating will save much more energy - but space heaters are great if you only need to keep one small room warm. 

Sarah Gale, Heating Category Manager at Toolstation said:

 

“If you’re just in one room and it isn’t necessary to heat the whole home, it can be more cost efficient to rely on a space heater than to wack on the central heating. These portable yet powerful heating systems warm up small indoor areas quickly which is perfect for those working from home looking to heat just the office.”

Turn down your heating

Depending on how much you lower your heating, you could save hundreds yearly. Reducing the temperature on your thermostat can save about 4% energy for every degree you lower it. 

Turn down your heating

Danielle Robinson, Central Heating Category Manager at Toolstation said:

 

“In the wintertime, we want our heating to keep us warm. However, you might not notice the effects if you were to lower the thermostat by a degree or two. This means you and your family could still get the benefit of a warm home, but you could save a bit of money when the energy bill comes.

 

It’s also important that your heating is set to come on for a time when you and your family can feel the benefit. For example, you could cut the midday heating burst particularly if no one’s in, but a mid-evening radiator switch-on could be considered more essential, particularly if you’re looking to cosy up to the TV”

Be mindful when using extractor fans

Extractor fans should only be used when necessary, as they can remove excess heat from your home. Switch them on when you start cooking, then turn them off once you’re done. 

 

However, air flow and extractor fans serve a purpose, protecting the home from mould and mildew and keeping us healthy. Make sure you're using the extractor fan often enough that moisture doesn't build up. 

Buy a humidifier

Humidifiers add moisture to the air, making your home feel warmer. However, they can cause problems with mould and damp if your home is not adequately heated and ventilated, especially in the winter. To avoid this, we recommend maintaining the humidity level between 30% and 50%. 

Invest in warm clothing

One of the best ways to save energy is to layer up with warm clothes in winter. Thermal tops, leggings, underwear and socks are excellent investments for your wardrobe. 

Get letterbox draught excluders

Letterboxes can create a draught, causing heat loss. Use draught excluders around the letterbox and under external doors to keep heat inside your home. 

Cover hard floors with carpets or rugs

Hard floors can add aesthetic value to your home whilst being practical to keep clean, but they don’t retain heat well. Add rugs or carpets to keep your home warm.

Fill any holes in exterior walls

Non-essential holes in exterior walls allow heat to escape. Filling them in helps prevent heat loss, making your home more energy efficient. Use wall filler or putty for a quick and effective solution. 

Clingfilm windows and doors

Adding an extra barrier to your windows and doors with clingfilm can prevent heat loss and drafts, acting like double or triple glazing. Although this is only a short-term fix, it is inexpensive and helpful during the colder months. 

4. Laundry energy-saving tips

Wash laundry on a low or eco setting

Most laundry, apart from underwear, activewear, bedding and towels, can be washed at lower temperatures. It’s also better for your clothes, preventing colour loss and other signs of wear. Refer to the manufacturer’s handbook for recommended settings. 

Wash laundry on a low or eco setting

Don’t overfill your washing machine

Overfilling your washing machine makes it less efficient, so you may have to rewash your clothes and waste energy.

Avoid drying clothes on radiators

Drying clothes on radiators prevents heat from dissipating around the room effectively. It also makes your radiators work harder to reach the desired temperature, using excess energy.

 

If you need to dry clothes inside, place a dehumidifier next to your clothes airer. The dehumidifier will suck the moisture out of the air surrounding your clothes so they can dry much faster.

Avoid using the tumble dryer

Throwing your freshly washed laundry straight into the tumble dryer can be tempting, but this uses a lot of energy. Instead, try air drying your clothes to reduce your bills, especially during the summer months when clothes dry quickly outdoors. 

Avoid using the tumble dryer

Clean the filters on your tumble dryer and washing machine

Lint and debris can quickly accumulate in the filters of your washing machine and tumble dryer. Clean them regularly to ensure your appliance runs efficiently.

Invest in a washing-up bowl

Filling a washing-up bowl to do the dishes is more efficient than running the tap, saving water and energy.

5. Water energy-saving tips

Spend less time in the shower

Cutting down on the time you spend showering is another way to save energy and water. Try showering in under 4 minutes to keep bills down. 

 

Also, taking showers instead of baths can cut energy costs.

Spend less time in the shower

Fit a water-saving showerhead

Use less energy and water when you switch to a water-saving showerhead. Water-saving showerheads reduce the water flow, which is set to its maximum on regular showerheads. Plus, you’ll still get the same great showering experience without any pressure loss. 

Shower at work or the gym

If your workplace or gym has shower facilities, make the most of this to lower your energy costs at home. 

Turn off the shower when lathering up

Although interrupting your shower may seem unappealing, you can save water and energy by turning off the tap while you lather up.

Turn the tap off when brushing your teeth

Another simple way to cut your water consumption is by turning off the tap while you brush your teeth.

Fill the dishwasher

Before running a dishwasher cycle, ensure it is full to avoid wasting energy.

 

Washing up is also great way to conserve energy - just make sure to use a washing up bowl rather than running the water continuously.

Fill the dishwasher

Reduce your combi boiler’s water flow temperature

Most combi boilers are pre-set with a higher flow temperature than needed. Reducing it to between 40˚C and 50˚C can save energy. Be aware that this tip is only suitable for combi boilers, as lowering the flow temperature in hot water cylinders below 50˚C can cause legionella bacteria in the water supply.

 

Make sure to consider the distance the water has to travel to get to your hot taps - the further the water has to travel, the more it will cool down on the way. Consult a heating engineer to determine the best temperature to set the water flow temperature to optimise it for comfort and energy saving. 

Danielle Robinson, Central Heating Category Manager at Toolstation says:

 

“Depending on the combi boiler model, you can usually adjust the boilers flow temperature by opening the flap to reveal the digital display. Once you’ve done this, you’ll likely see two dials or settings – one which controls the hot water from your taps and the other controls the radiators in your home. You’ll just need to adjust the temperature for the radiators and can usually adjust the temperature slightly – without noticing too much of a difference. If you do adjust your boiler settings, it’s useful to take a picture or write down a note of the current settings so you can readjust should you need to."

Turn off your boiler’s pre-heat function

Many combi boilers have a pre-heat function, meaning water in the system is always kept at a specific temperature to provide hot water on demand. Turning off the pre-heat function can save energy, especially if hot water isn’t required for most of the day while you’re at work. 

Turn off your boiler’s pre-heat function

Danielle Robinson, Central Heating Category Manager at Toolstation says

 

“The pre-heat function on a boiler allows hot water to always be ready whenever you turn on a tap. However, using this setting could mean you’re heating water unnecessarily if you’re not using it for hours on end e.g. overnight or during the working day. If it works for your routine, turning off the pre-heat function could save you quite a bit on heating without inconveniencing you too much. It may mean you have to wait slightly longer for the shower to get warm in the morning but it will save your boiler from firing up all day and night unnecessarily.” 

Put a timer on your boiler

Set a timer on your boiler, so water is only heated when needed. This tip can be followed for any boiler type. 

Danielle Robinson, Central Heating Category Manager at Toolstation says:

 

“It’s unlikely you’ll need your radiators and hot water on constantly – even in the height of winter. If it works with your daily routine, it may be worth setting a timer on your boiler so that it’s only firing up when you’re there to benefit from it. For example, if you know you shower morning and night, it could be worth making sure water is only heated for these times. Likewise, if you know you’re out of the house for work, it’s worth making sure the heating is just on when you’re up and getting ready in the morning and when you return from work."
