Big Energy Saving Week 2026 is here, and being the start of this new year it's an ideal time to make sure your home heating is working smarter, not harder.
Wiser customers are already ahead of the curve, but there are even more ways to save energy, reduce bills, and lower your carbon footprint.
Read on to find out about limited time discounts on our most popular energy-saving add-ons!
Here are 7 practical heating tips to help you save energy right now:
1. Take Advantage of Room-to-Room Control
Heating every room all the time wastes energy. With Wiser’s smart radiator thermostats, you can set different schedules for each room – so you only heat the spaces you need.
2. Lower Your Setpoints by 1°C
Dropping your thermostat by just 1°C can cut heating costs by around 7%* without sacrificing comfort. Try it for a week and see the difference.
3. Activate Away Mode When You’re Out
Heading out for the day or away for the weekend? Switch on Away Mode in the Wiser Home app to reduce heating while you’re gone. It’s an easy win for both your wallet and the planet.
4. Optimise Your Heating Schedule
Review your heating schedule regularly. Align it with your routine so you’re not heating rooms when you’re asleep or out. Wiser makes this quick and simple.
5. Close Curtains at Night
Thick curtains help trap heat inside during colder evenings. Open them during the day to let in natural warmth from the sun.
6. Bleed Your Radiators
Trapped air makes radiators less efficient. Bleed them at the start of the season to ensure your system runs smoothly and uses less energy.
7. Service Your Boiler
An annual boiler service keeps it running efficiently and safely, helping you avoid costly breakdowns and wasted energy.
