Big Energy Savings Week

Posted on Jan 15, 2026

Big Energy Saving Week is here to help people save energy and money at home! The Energy Saving Trust and the Department for Energy Security and Net Zero are supporting individuals to take action. The week shines a spotlight on energy efficiency and helps people understand what support schemes are out there, which can help keep their homes warm without extra cost.

The timing of Big Energy Saving Week is important as it lands on one of the coldest weeks of the year, when energy bills are often at their highest and households can feel under the most pressure.

Energy costs can be a serious burden, especially for low-income households, the elderly or those living in poorly insulated homes. Around 12 million UK households are struggling with energy costs, and Big Energy Saving Week is about more than just saving money, it’s about health and wellbeing too.

Small changes really do matter. Simple actions such as switching to LED lightbulbs or turning down the thermostat slightly can add up to make a real difference to your energy use and bills.

Energy-saving home investments

Making improvements to your home can make a real difference to your energy bills. From inexpensive fixes to higher-level investments, here are some of our favorite ways to take your energy saving to the next level.

• Home insulation – Around 60% of your home’s heat loss is through the walls and roof. Investing in good quality insulation can be very beneficial in lowering your energy bills long term. Depending on the size of your home, loft, and cavity wall insulation costs around £1,000. Do you qualify for free home insulation? Take a look here.
• Double (or even triple) glazing – Upgrading your windows will improve how your home keeps in the heat during the cold weather. The lifespan of double glazing is around 20-35 years. Is it time to replace your windows?
• Replace your boiler – Modern boilers are more energy efficient than older models. An energy efficient boiler could save you up to £840 a year! The typical cost of a new boiler ranges from £1,700 – £3,500. With these types of savings, you’ll have earned your investment back in just over 2 years!
• Replace older appliances – It might be worth replacing old appliances which are ready to be retired with a new energy efficient model. ‘A’ grade are usually the most efficient and ‘G’ being the least. Check out the Energy Saving Trust for more info on energy labels for appliances and Sust-it which ranks products by energy use.
• Heat pumps – Air source heats pumps are a new, innovative way to heat your home. They use electricity to take heat from the air and use that heat in your home. The saving from investing in heat pumps will soon outweigh the larger upfront investment! You may qualify for a grant to help towards the cost of an Air Source Heat Pump.
