1. The 1-Degree Rule

Resolution: I’ll turn the thermostat down by just 1°C.

  • Reducing room temperature by 1°C can cut heating bills by ~8–10%

  • Most homes are overheated without realising

  • Habit framing: comfort, not cold

Top Tip: 18–19°C for living areas, 16–18°C for bedrooms


2. Heat the Room You’re In

Resolution: I’ll stop heating empty rooms.

  • Close doors

  • Use TRVs properly (not all on “5”)

  • Don’t fight unused space

Your boiler works harder the more space you ask it to heat.


3. The “On Earlier, Off Sooner” Habit

Resolution: I’ll stop blasting the heating.

  • Turning heating on earlier at a lower temperature is more efficient than sudden high demand

  • Boilers work best at steady loads

Modern condensing boilers are most efficient when running gently for longer.


4. Stop Using the Boiler as a Light Switch

Resolution: I won’t keep turning the heating on and off all day.

  • Constant cycling = wasted gas

  • Use a programmable timer instead of panic-boosting


5. The Annual Boiler MOT

Resolution: I’ll service my boiler every year.

  • Improves efficiency

  • Reduces breakdowns

  • Can spot issues before gas bills creep up


6. Lower Flow Temperature, Higher Savings

Resolution: I’ll ask my engineer to optimise my boiler.

  • Many boilers are set too high from install

  • Lower flow temps = better condensing = less gas used


7. Bleed Radiators Once a Year

Resolution: I’ll stop heating air instead of rooms.

  • Cold spots mean wasted energy

  • Takes 5 minutes

  • Improves heat output instantly


8. Upgrade Controls Before Upgrading the Boiler

Resolution: I’ll make my heating smarter, not bigger.

  • Smart thermostats

  • Zoning

  • Weather compensation


9. Don’t Block the Heat You’re Paying For

Resolution: I’ll stop blocking radiators.

  • Sofas, curtains, furniture = trapped heat

  • Room feels cold → thermostat goes up → bill goes up


10. Ask a Gas Engineer, Not Google

Resolution: I’ll get advice that actually fits my home.

  • Every property heats differently

  • A 5-minute conversation can save hundreds over a year
