Empty homes turn small leaks into major damage because nobody is there to notice, and most Scottish homes have no meter to give a warning. Insurers commonly restrict cover after 30 consecutive days empty. Before winter, either keep background heating on or drain the system down, and arrange regular inspections.
Holiday Homes and Empty Properties: Managing Leak Risk
A leak in an occupied house gets noticed within hours. The same leak in a cottage in Argyll that sits empty from October to Easter has all winter to work, and the owner finds out in April when the door swings open onto collapsed ceilings and a smell that has had months to establish itself. Scotland’s holiday lets, second homes, inherited properties awaiting sale and rentals between tenants all share the same core weakness: no occupant, no early warning.
This guide covers why an empty property water leak does so much damage, the insurance small print that catches owners out, the heat-or-drain decision every winter, and the routine that keeps a distant property safe.
What’s in this guide
Why empty properties get hit hardest
Three things protect an occupied home from leaks, and an empty one has none of them. Nobody hears the drip or spots the stain. Nobody runs the heating that keeps pipework above freezing. And in Scotland there is not even a bill to raise the alarm: most households are unmetered, paying for water through council tax, so a leak can run for months without costing a penny more or leaving any trace on paper.
Winter concentrates the risk. Scottish Water reported around 3,100 bursts on its network in winter 2023/24, with over 30% happening on customer property, and unheated buildings freeze first. The classic empty-property disaster is a small pipe split during a cold snap in January that thaws and flows freely in February, discovered at half term.
Unoccupancy clauses: the insurance catch
Here is the part many second-home owners only learn after the damage. Standard home insurance quietly changes once a property sits empty. Specialist insurer HomeProtect, for example, treats a home as unoccupied once it has not been lived in for more than 30 consecutive days, and restricts escape of water cover for temporarily unoccupied homes between 1 October and 1 April, precisely the months a Scottish holiday home stands empty. On its dedicated unoccupied policies, escape of water is excluded altogether. Terms differ between insurers, but the pattern of a 30 or 60 day limit with winter water restrictions is common across the market.
The conditions attached matter as much as the exclusions. Insurers typically expect background heating or a fully drained system in winter, and regular documented inspections, in HomeProtect’s case at least every 14 days for long-term empty homes. Miss the conditions and a claim can fail even inside the cover period. Our guide to how home insurance treats water leaks explains the escape of water basics; for an empty property, read your policy’s unoccupancy definition before anything else.
Heat it or drain it: the winter decision
Scottish Water’s Protect your Pipes campaign gives the framework for winter: heat, insulate, protect. For an empty property that translates into a genuine either-or decision, and both answers are respectable.
Keep background heating on
- Pipework stays above freezing through cold snaps
- The house stays aired and ready for short-notice visits or guests
- Usually satisfies insurer heating conditions, check the required setting
- Works best paired with insulated pipes and tanks and a timer or frost stat
Drain the system down
- No water in the pipes means no burst, the surest protection there is
- Suits properties left all winter with no visits and no heating
- Needs doing properly: water off at the stopcock, taps run empty, heating system treated per its type
- Recommissioning takes effort in spring, and the house cannot host guests meanwhile
What does not work is the halfway house: heating off to save money, water left on, and hope. That combination produced a large share of the winter callouts we attend. Our Scottish winter pipe protection guide covers lagging, frost stats and draining down in detail.
The key-holder plan
Every empty property needs a named person within reach of it, holding keys and a short written brief. For a holiday home in Dumfries and Galloway owned from Glasgow, or an Ayrshire cottage owned from London, that person is the difference between a damp patch and a ruined house.
What the key-holder brief should contain
- Where the stopcock is and proof it turnsThe first job in any water emergency. Our guide to finding the stopcock helps you document it once, properly.
- An inspection routine that matches the policyIf the insurer requires a check every 14 days, the routine is every 14 days, dated, with photos.
- What to look for on each visitCeilings, under sinks, around the boiler and hot water cylinder, toilet cisterns, the smell of the place when the door opens. Damp has a smell that arrives before stains do.
- Boiler pressure noted each visitA sealed system quietly losing pressure between visits is a leak announcing itself early.
- Who to phoneOwner, insurer, plumber, and a leak detection company for anything that cannot be seen.
Leak sensors and shut-off valves: worth it, with limits
Technology has made distance ownership easier. Wireless leak sensors under sinks and beside cylinders send a phone alert when they get wet, smart thermostats report the indoor temperature daily, and automatic shut-off valves can close the supply the moment abnormal flow is detected. For a property nobody visits weekly, a few sensors and a connected thermostat are cheap insurance and we would encourage them.
Be honest about the limits, though. Sensors only watch the spots they sit in, batteries and signal fail quietly, and an alert from 200 miles away still needs a key-holder to act on it. Detectors shorten the time a leak runs undiscovered. They do not find the leak, and they do not replace the inspection routine your insurer requires.
Arriving at an empty property to find a water leak
If you open the door to running water or fresh damage, the order is: stop the water at the stopcock, open taps to drain the pipes, keep clear of any electrics that got wet, and photograph everything before you touch it. Our guide to the first ten minutes after a burst pipe walks through each step.
If the house is damp but you cannot see a source, resist the urge to start lifting carpets on a guess. A leak that ran unseen in an empty house has usually travelled, and the wet room is often not the leaking room.
Frozen pipework needs particular care: a pipe that froze may have split in several places, and each split only shows itself as the ice thaws. Our frozen pipes guide covers safe thawing. For anything hidden, call us on 07700 152 467 and we will pinpoint the damage before repairs begin, with a written report your insurer will want for the claim.
Frequently asked questions
How long can I leave my house empty before insurance is affected?
Commonly 30 to 60 consecutive days, depending on the insurer. HomeProtect, for example, classes a home as unoccupied after more than 30 consecutive days without anyone living there, and restricts escape of water cover for empty homes over winter. Check your own policy’s unoccupancy definition and conditions.
Should I turn the water off in an empty house?
If nobody needs the supply, yes. Turning off the stopcock removes most of the risk at a stroke, and draining the pipes afterwards removes nearly all of it. For winter absences the choice is between a properly drained system and background heating with the water left on. Water on, heating off is the worst of both.
Would a leak show up on a water bill in Scotland?
For most homes, no. The majority of Scottish households are unmetered and pay for water through council tax, so consumption never appears on a bill. An empty property can leak for months with no financial signal at all, which is why physical inspections and leak sensors matter so much.
Are smart leak detectors worth fitting in a holiday home?
For a property you cannot check weekly, yes. Sensors under sinks and near the cylinder, plus a thermostat that reports temperature remotely, shorten the gap between a leak starting and someone knowing. They complement rather than replace the inspection visits your insurer is likely to require.
What should I do if I find damp but no obvious leak in my empty property?
Stop the water at the stopcock, photograph the damage and get the leak located professionally before any repairs or drying begin. Water that ran unnoticed in an empty house has usually travelled from its source, and a detection survey with a written report also gives your insurance claim its evidence.
