Start with the free and cheap wins

Before buying anything, check your tariff, ask your supplier for a smart meter, and look at where your energy actually goes. Heating and hot water make up most of a typical UK home's energy use, while appliances, cooking and lighting make up much of the electricity bill.

Devices that need no installer

• LED bulbs – a quick swap with an immediate effect on lighting use
• Smart plugs – schedule heaters, lamps and chargers
• Standby savers – cut power to TV and games consoles
• WattLock – one per socket circuit, plugged straight in

How to choose

Match the device to the problem. If you leave lights on, LEDs and timers help. If heating is your biggest cost, controls and draught-proofing matter most. For a simple fit-and-forget addition to every socket circuit, WattLock is designed to be plugged in once and left alone.
