5 simple strategies to improve energy efficiency

Originally published 19 November 2013. The figures and the Green Deal scheme referenced have since changed - see our latest guides.

The cost of energy in the UK rose substantially over the years before this was written. Effectively managing your household power consumption and heat dissipation can save hundreds of pounds a year on bills and lower carbon emissions. Here are five ways to improve energy efficiency.

1. Improve your insulation

A well-insulated loft together with cavity wall insulation could improve efficiency and save a meaningful amount per year, particularly in older houses. At the time, subsidised loans were available through the Green Deal scheme, which has since closed.

2. Install a more energy efficient boiler

If your boiler is more than a few years old or constantly malfunctioning, check its efficiency grade. If it is graded D or lower, consider switching it out. Recent advances mean the initial outlay can be clawed back over the following months. Government schemes have at times part-funded replacements for eligible households.

3. Keep your fridge and freezer full

It costs more energy to cool air than solid matter, and solid or liquid matter conducts temperature more effectively. Keeping both tightly packed, but not overloaded, reduces the energy your cooling appliances use.

4. Turn your thermostat down

Reducing the temperature of your home by one degree can cut your heating bill by up to 10%. Minute lifestyle changes accumulate vast savings over time.

5. Unplug or switch off at the wall

Laptops, DVD players, televisions and chargers still use electricity on standby or plugged in. Switching them off at the wall when not in use significantly reduces overall power consumption.
