How To Reduce Your Gas Usage and Utility Bills 2021


With gas prices rising by ridiculous levels it may be worth checking a number of things which will help to reduce your overall usage of gas. I have spent the last three months implementing a number of the things shown in my list below and overall my gas usage has dropped and my bills have remained the same. Hopefully there will be something listed below which you can implement to help you achieve the same or reduce your costs all together.

How To Reduce Your Gas Usage and Utility Bills 2021


The biggest way to reduce your gas usage and reduce your utility bills is to stop wasting the heat that the gas is producing. This may seem obvious but how many times do you walk down a street and see a house with all the windows open and the combi boiler flue on the side of the house producing steam, showing the occupants have also got the heating on. If the ambient temperature outside is low enough to open all the windows why do you need the heating on? The best way to reduce wastage is to optimise how you use your heating system. Listed below are a number of items to consider


  • Roof insulation – Is there a thick layer of high specification insulation material?
  • Windows – consider changing to double glazing. 
  • Drafts – Gaps in doors, windows, floors and ceiling all increase wastage of heat. This includes open chimneys. If your not using it block it up.
  • Floor insulation – Are your floor boards insulated?
  • Central heating pipes – Are they insulated to ensure they are providing optimum hot water to the radiators and not other none essential areas. For instance in old homes with suspended floors check that the heating pipes are lagged. You can lose around 25% of your heat by using unlagged pipes.
  • Wall Insulation.

Heating Appliances

  • Open flame gas fires – 70% of all the heat generated by an open flame gas fire goes up the chimney. That 70% wasteage of your burnt gas. Speak to a gas fire retailer or showroom regarding changing to a high efficiency glass fronted gas fire. Or, better still, block up the chimney and use a flueless (no chimney) product for your secondary heating needs. Or, before you do that, ask if you really need secondary heat. If yes, products to consider include a bioethanol fireplace or electric fire. Why? Every product that uses a chimney draws heat from your home regardless of whether the appliance is being used or not. This is due to the air convection process that is required to make the appliance work.
  • Gas boiler – If your gas boiler is old and inefficient it may be time to upgrade to a new modern version. A 24kw boiler with a 70% rating is wasting 7Kw per hour of gas. Check your gas bill to find out how much you pay per kw. Then times that by how many hours per year your boiler is switch on. You’ll most likely get a shock at how much money your wasting.
  • Radiators – Add a product like ENDOTHERM to your radiator watee as it has been proven to reduce heating bills by up to 15%. Also clean dust off your radiators as it creates insulation that refuces heat radiation. If possible add reflectors on the wall side of the radiator to direct heat into the room and not into the walls.

Other Considerations

  • Install a smart meter then you can monitor your usage accurately and avoid estimated bills.
  • Install thermostatic radiator valves and adjust them to a temperature level that makes the room comfortable.
  • Adjust your room thermostat to a comfortable level. It was reported on TV that just trimming your thermostat from 22 degrees to 21 degrees could reduce your gas bill by £50/year.
  • Adjust all the radiators so the hot water from the boiler heats the rooms that are being used. For instance an unused spare bedroom does not need to be at 22 degrees all the time. Adjust the radiator valves.
