Leaving a property empty in winter

Check insurance and heating requirements

Read the building-insurance conditions before leaving. The policy may require a minimum heating setting, the water to be isolated or drained, and regular recorded inspections. Follow the policy and the heating-system manufacturer’s guidance; do not assume that switching everything off is safest.

Reduce avoidable plumbing risks

• Disconnect outside hoses and, where the installation allows, isolate and drain exposed outside pipework.
• Confirm the internal stop tap and local isolation valves operate without forcing them.
• Repair small leaks, running toilets, dripping taps and unreliable valves before the property is left unattended.
• Insulate accessible pipes in lofts, garages and other unheated spaces, keeping valves and joints visible for inspection.
• Do not leave a tap running as a general freeze-prevention measure; it wastes water and does not protect every section of pipework.

Arrange inspections and emergency access

• Give a trusted keyholder the stop-tap location, alarm details and contact numbers.
• Agree how often the property will be checked and keep a dated record if the insurer requires it.
• During cold spells, look for loss of water, damp patches, unusual boiler pressure, dripping overflow pipes and cold areas around exposed plumbing.
• Make sure post, bins and exterior appearance do not advertise that the property is empty.

What to do after a freeze

Do not simply restore full pressure and leave. Inspect accessible pipes first, then open the supply slowly while someone watches for leaks. A split may only begin to leak as the ice melts. If there is any doubt, keep the supply isolated and arrange an inspection.
