Thrifty tumble-drying tips

  • Choose a more efficient tumble dryer to keep your bills down.
  • Fully fill Try to fit the maximum load in your tumble dryer every time.
  • Use a high spin speed on your washing machine This will get your washing as dry as possible before using your tumble dryer.
  • Clean the lint filter every time you use the machine A blocked filter prevents the hot air from circulating freely, so clothes take longer to dry.
  • Position your dryer in a well-ventilated room This will stop the tumble dryer from overheating.
  • Sensor models Dry clothes for ironing together with other clothes. Start the load with an iron-dry setting, remove the clothes for ironing, and then put the rest on a cupboard-dry program.
  • Minimise use Make the most of good weather by drying your clothes outside, and leaving the tumble dryer switched off.
  • Fasten duvet covers to stop small items getting trapped inside the cover and staying damp
  • Untangle everything between your washing machine and your dryer - large knots of washing take longer to dry
