Two-fifths of Brits avoid thinking about the approaching colder weather altogether so it doesn’t spoil their summer. To help the nation get prepped for winter, Smart Energy GB today launches the ‘Winter Prep Checklist’ created in partnership with National Energy Action and ‘Sort Your Life Out’s’ professional organiser, Dilly Carter. 3 weeks before winter: Check the settings on your heating and hot water timer. 2 weeks before winter: You may need to bleed your radiators every few months. 1 week before winter: Taking care of draughts before the temperatures drop means you'll stay warmer and save on heating costs once winter sets in.
