Npower sent out 12m unsolicited energy saving light bulbs in late 2009

Npower customers switching to the energy supplier's paperless billing service will receive a free electricity monitor in return, provided they've never had one before.

The free 'smartpower' monitors provide real time information on how much electricity is being used in your home, and how much it's costing you.

Free energy monitors

Energy monitors are widely available and usually cost around £40, but Npower is the latest in a series of energy suppliers - including British Gas, Eon and Scottish and Southern Energy -  to provide them free of charge to its customers.

If your supplier isn't offering free monitors, our smart meters and energy monitors review shows you three Best Buys that won't break the bank.

Smart meters and energy monitors

Despite their name, the smartpower monitors are not to be confused with smart meters, which the government wants to roll out to every home by 2020.

While smart meters transmit details of energy use to your supplier - and so remove the need for meter readings - energy monitors are designed to help you cut energy consumption by allowing you to keep track of how much energy you're using.

If you're not sure about the difference between smart meters and energy monitors, you're not alone. Which? research reveals that one in three Which? members is still baffled by the difference. For details of how each one works, have a look at our guide - smart meters and energy monitors explained.

Energy savings

Npower claims that electricity monitors are proven to cut energy consumption by up to 15% in the first year - but any savings will vary between households and will depend on behavioural changes.

Energy monitors are just one way of helping you control your energy use. We've put together a list of energy-saving Best Buy appliances - from washing machines to fridge freezers - which pair low running costs with top-class performance.

Lower your gas and electricity bills

You can compare energy prices and switch to a new gas and electricity supplier on Which? Switch. People who switched with us between 1 October and 31 December 2013 are predicted to save an average of £234 a year on their bills.
