During the cold winter months, when temperatures regularly drop below zero, the freezing weather can cause damage to your business water pipes. This may potentially result in business downtime or even closure. So regardless of what the weather brings us this season, businesses should always take time to prepare for the worst.

Before locking up for the festive season, complete your business premises winter checklist to ensure your business is protected over the cold weeks ahead:

  • Locate your internal stopcock - it may be under the kitchen sink or in the staff toilets.
  • Make sure your office boiler has been serviced.
  • Closing for a few days? Leave the heating on low or drain down the system.
  • Insulate water tanks and lag your pipes. Remember not to leave any gaps at bends, valves, or fittings. Lagging material is available from all good DIY stores.
  • If there is a loft space, check loft insulation is in good condition.
  • Ensure pipes, cisterns, and tanks in unheated areas such as lofts are lagged.
  • Leave loft doors open to allow warm air to circulate.
  • Repair dripping taps - even a small trickle can result in frozen pipes.
  • Keep a separate supply of drinking water in case of emergency.
  • Make sure you have adequate insurance against plumbing and drainage emergencies such as burst pipes.
  • Note the name and number of an industry recommended plumber in case of emergency.
  • Castle Water’s contact and emergency contact numbers are listed below and can also be found on our website.
