How can I make my washing machine more efficient?
Most households use their washing machine around five times a week. This means that costs mount up. Here are some tips on how to make doing your laundry less expensive:
When possible, wash your clothes at 30 degrees C. This will save you around £10 off your annual bill.
Quick programmes are convenient, but try not to rely on them. They won't save you money, as the washing machine will have to heat the water up to a higher temperature in order to clean the clothes in a shorter space of time.
Fill your washing machine with the maximum load.
