Winter is coming! The car scrapers are out and there’s no hiding from the fact that temperatures are falling. Now is the ideal time to think about how you can protect your business from the nightmare scenario of frozen – and potentially burst – pipes over the holiday period.

By following our precautionary measures, you can keep your business Winter Wise and minimise the risk of a nasty freeze this winter.

  • It may seem obvious but keeping your business warm is one of the best ways to prevent any pipes from freezing. Keep your premises heated, and if your business is going to be closed for a period of days, consider keeping the heating on a low setting while you are away.
  • If possible, leave doors open including cabinets and cupboards. This will help the air circulate and encourage the warmth to move to those hard to reach crevices pipework is normally located in.
  • If the property is vacant over winter, consider turning off the water supply and draining the system. It’s also a good idea to regularly visit a closed business to check for any issues.
  • Pipes can be protected by applying insulating tape directly on or around the pipes. Water pipes, tanks or toilet cisterns in unheated outbuildings or exposed places should also be insulated. If not in use over winter, consider having them drained.
  • Minimise draughts, which can cause pipework to freeze, by fitting draught excluders on doors and windows. Always ensure that you have adequate business insurance in place as leaks and burst pipes can be very costly to your business.
  • Get Winter Wise now and be prepared! Find and know how to use your stopcock and have the phone number of an emergency plumber to hand. Have an emergency kit ready which includes important contact numbers and an emergency supply of fresh, clean drinking water.
