Holiday cottages left empty in winter: frost protection priorities
A holiday cottage that stands empty for stretches of winter faces a real risk of frozen and burst pipework if the heating system is simply switched off between bookings. Reliable frost protection settings and monitoring matter more here than in a permanently occupied home.
Understanding an unoccupied holiday cottage before you spend money
Most modern boilers include a frost protection function that fires the system briefly if internal temperature drops too low, but this depends on the boiler being left powered on and the thermostat set appropriately rather than switched off entirely at the mains. Remote monitoring or smart thermostats let an owner or caretaker check the property is holding temperature without visiting in person, which is particularly useful for cottages some distance from where the owner lives.
An unoccupied holiday cottage — the facts that change the job
- Frost protection only works if the boiler is left powered on, not switched off
- Smart thermostats allow remote temperature checks between bookings
- Pipework in unheated parts of a cottage needs proper insulation regardless
- A trusted keyholder or caretaker check is valuable during longer void periods
- Water supply isolation may be worth considering for extended vacancy periods
Who should undertake the work
- Gas appliance work must be completed by a suitably qualified Gas Safe engineer
- Oil appliance work should be completed by a suitably qualified OFTEC technician
- Jamie Crawford Heating states both Gas Safe and OFTEC registration
Questions we get asked
- Should I turn the heating off completely between guests?
- This risks frozen pipework in cold weather — leaving frost protection active is generally safer for an unoccupied property.
- Can I monitor the cottage remotely?
- Smart thermostats and some boiler control systems allow remote temperature checks, which suits cottages you can't visit regularly.

Straight answers on an unoccupied holiday cottage
The honest position: Frost protection needs the system left powered and properly set, not switched off — remote monitoring adds peace of mind for cottages you can't check daily.
