Boiler Prep Checklist: Getting Your Heating Ready for Winter

The worst time to discover your boiler has a fault is the coldest week of the year — when engineers are busiest and a breakdown is most disruptive. A short autumn checklist can help you avoid it.

Before the Cold Snap Hits

  • Book your annual boiler service — ideally in September or October, before demand peaks.
  • Bleed every radiator in the property to remove trapped air and restore even heating.
  • Check your boiler's pressure gauge is within the manufacturer's recommended range.
  • Test your heating on a full cycle, including hot water, rather than just switching it on briefly.
  • Insulate any exposed external pipework to reduce the risk of freezing and bursting.

Know Your Emergency Plan

Make sure you know where your stopcock is, keep your boiler's model details handy, and save a trusted engineer's number in your phone. If your boiler does fail in winter, having this ready means a much faster fix.

Book your winter boiler service now and avoid the January rush — we offer fixed-price servicing and priority booking for returning customers.
