Energy and carbon saving

In partnership with Brunel University, we are sharing these tips to help you reduce the units you use.

On their own, these changes may seem small, but collectively they can make a significant difference.  

Turn your heating down 

  • Each degree you cut your home thermostat will result in a 4% reduction in your energy consumption - that's a £100 saving per year based on a typical home. (MoneySavingExpert)
  • When indoors, try and keep the living room temperature at a maximum of 21°C and other rooms at 18°C, which is also considered an ideal temperature for most people to sleep.
  • Leaving your gas central heating on low all day is not cheaper; only put it on when you need it. (Students Organising for Sustainability, via Brunel University)
  • Using radiator thermostats will allow temperature control in individual rooms, so that rooms that are less well used - or not needing to be heated - can be isolated and use less energy.   

Reduce the water you use

  • Only boil the amount of water you intend to use, ensuring you follow the minimum water levels of your appliance.
  • Run your dishwasher when it is full, and be careful with excessive rinsing and use of kitchen and bathroom taps.
  • Switching from baths to a 4-minute shower will most likely result in a saving on your heating bills.   
  • Cutting just a minute off your shower time could save £207 a year in energy bills, and a further £105 a year in water bills if you have a meter - that's £312 a year, based on an average 4-person household. (MoneySavingExpert)
  • Try and only wash full loads and run on lower heat settings. It is estimated that switching to full loads and only washing on 30 degrees could save a typical household £73 a year. (MoneySavingExpert) 

Switch it off

  • Unplug all chargers when devices are fully charged. Overcharging uses unnecessary energy and can reduce the lifespan of the battery.   
  • Turn off lights when not in use and, where possible, switch to energy-saving lightbulbs.
