Why it matters
If water in pipes freezes, it expands and can split them. When it thaws, the leak can cause serious damage before anyone notices. Boilers' condensate pipes can also freeze, stopping the boiler from working.
Sensible settings
Before you go away in winter:
- Use the boiler's or thermostat's frost protection or holiday mode if it has one
- Alternatively, set the thermostat low and leave the heating on
- Leave the boiler powered on so its frost protection can work
- Open loft hatches and cupboard doors where pipes run, to let warmth reach them
- Know where your stopcock is in case of a leak

Empty properties and second homes
Properties left empty for longer may need draining down or regular checks. Smart thermostats let you monitor and warm a property remotely. Check your home insurance, as policies often have conditions for unoccupied homes.
