The energy bill soars. What can I do with my central heating system?


The winter energy bill surge is more likely to take households by surprise this year and yes, working from home will even add more weight to your energy consumption. You might know some energy-saving tips such as opening the curtains to let the sun in if it is a sunny day, leaving the oven door open after cooking (be careful if the children are around) and even training your pet to sit on your laps.



Considering over 55% of the energy bill is from heating and hot water according to Energy Saving Trust (Apr 2020), it is worth getting some expert tips on using heating controls and maintaining your heating system to reduce your energy bills.


  • Lower your average temperature 1 degree less. Ideally, the indoor temperature is between (18 - 20 degrees). With just one degree difference, you can save up to £80/year according to Uswitch.

  • Only heat your home when you need it. If you keep the heating on all day (even low heat), you are losing energy all day.

  • Making sure your system water is clean. Over time, your central heating system will accumulate dirty water (sludge) and it can block pipes and radiators. So the radiators do not work properly or get to temperature. Free of sludge will mean that your heating system is more efficient. If you are not sure, always check with a qualified gas engineer and if necessary, you may need your system Powerflushed.

  • If possible, get a smart meter. With a smart meter, you are more aware of how much you are spending in real-time and understand where your energy goes. All the energy suppliers are installing them as a part of an upgrade to the UK’s energy system. You can always ask your supplier.

  • Last but not least. Check your boiler's lifespan. If your boiler is over 10 -15 years old and even if it is still working, consider a modern condensing boiler. Most current condensing boilers are A-grade which mean they have efficiencies of around 95% while the older boilers are typically 60-70% efficient. Replacing an old G-rated boiler with an A-rated one you could save £205 per year according to the Energy Saving Trust.

Reducing our energy use is a WIN-WIN, not only does it save us money but encourages us to think about our carbon footprint as well as how to live a more sustainable net-zero future.
