Revealed: the hidden energy wasters in your home

Originally published 16 July 2019. Some figures have since changed - see our latest guides.

We rely on appliances every day. Cutting them out entirely is not practical, but we can be responsible and limit energy use wherever possible. Tackle these hidden energy wasters as a place to start.

1. Washing machines and tumble dryers

Modern washing machines are more economical, but inefficient use makes them big energy wasters. Not filling loads and washing too hot are the common mistakes. Detergents work effectively at 30 degrees. Air drying clothes saves substantial electricity and extends garment life.

2. Standby devices

Entertainment devices draw power on standby. The biggest culprits are wireless routers, printers, set-top boxes, hi-fis, chargers, games consoles, alarm clocks and TVs. Turn them off when not in use, and use an extension lead so you can switch several off at the wall.

3. Inefficient fridge-freezers

An A+++ rated fridge uses around 80% less energy than a D-rated one. Avoid leaving the door open and defrost the freezer whenever ice builds up.

4. Draughts and poor insulation

A draughty, poorly insulated home means fighting an uphill battle with heating, losing warmth before you benefit from it. This costs money all year, not just in winter.

5. Old or inefficient central heating

An outdated boiler is a major energy waste. A-rated boilers convert over 90% of energy into heat, while G-rated boilers waste more than 30%, around £30 lost per £100 of bill. Since 2010, all newly installed boilers must be A or B rated by law. Checking your boiler rating indicates your current efficiency.
