Saving money on your bills is probably the biggest consideration when looking at the energy efficiency of an appliance, but it also goes a long way towards helping the environment in the long run. Like all appliances, washing machines are subject to the energy efficiency grading of A+++ down to G, with A+++ being the most efficient and G being the least.
It’s argued that the closer you have to an A+++ rated appliance the more you save, and while this might only amount to a few pence with each wash, it can quickly add up over a year.
In some respects the technology you use will inform its efficiency, a machine with more functions might cost you more money but may have energy saving settings for you to utilise. Additionally, if you live in an area where electricity is cheaper at night, you might be able to use this to your advantage, shaving extra money off your bills.
