Last updated: 1 August 2026 — Scotland Leak Detection
A property factor water leak in a Scottish tenement means the factor instructs repairs to common pipes, then bills each flat its share under the title deeds or Tenement Management Scheme. The factor cannot force an owner to fix a leak inside their own flat. If a factor stalls, Under One Roof recommends escalating to the council’s Environmental Health team.

What a property factor actually does
If you own a flat in a Scottish tenement, you probably have a property factor managing the building. A property factor water leak tests what that factor actually does, because the role is narrower than most owners assume. A factor is a managing agent, appointed collectively by owners to arrange maintenance and repairs to the parts everyone shares: the roof, the close, and any common pipework serving more than one flat.
The factor doesn’t own the building and doesn’t decide who pays what out of thin air. Their authority comes from the management agreement each owner signs, and from the title deeds that set out how costs get split. When a leak turns up in a shared pipe, the factor’s job is to get a contractor out and invoice owners for their share. They are not an insurer, a plumber, or a court.
We see this most weeks in older sandstone blocks across Glasgow and Edinburgh, where one supply pipe serves four or six flats. Nobody chose that layout, but a leak in that shared section is everyone’s problem, and the factor has to coordinate the fix.

Spotting the source before anyone pays a penny
A thermal scan like this one shows where moisture is tracking through a wall, before plaster starts to bubble. For a factor, that image is the starting point for every decision that follows: common pipe or private, and which flat’s cost share applies.
Common repairs vs your own flat
The single most important distinction in any tenement water leak is whether the pipe belongs to everyone or to one flat alone. According to Citizens Advice Scotland, Scottish Water is responsible for mains pipes up to the property boundary, and the owner is responsible for pipework within it. That private line usually stops at pipes serving a single flat.
Shared supply pipes are different. Citizens Advice Scotland notes that owners share responsibility for maintaining these, and repair costs are split per the title deeds, or the Tenement Management Scheme where the deeds don’t say. This is the split a factor works out before a repair van gets booked.
Where a property factor water leak decision usually lands
In practice, three situations come up again and again:
- A leak inside one flat’s own pipework. That owner sorts it and pays for it. The factor’s role stops at passing on a complaint from a neighbour.
- A leak in a shared supply pipe, the roof, or a common wall cavity. This is the factor’s remit. They instruct the survey and repair, then split the bill.
- A leak where the source isn’t obvious yet. This is why a factor often calls in outside help before committing anyone’s money.
How owners’ cost shares work
Once a factor confirms a leak sits in common pipework, the next question every owner asks is how much they owe. The answer sits in the title deeds first. Many older tenements have a deed of conditions setting fixed shares, sometimes equal, sometimes weighted by floor area. Where the deeds are silent, the Tenement Management Scheme sets the default, splitting costs equally among the flats that benefit.
A factor’s invoice after a common repair should show the total contractor cost and each flat’s calculated share. A good factor points to the clause in your deeds rather than just quoting a number.
This is also where a factor-commissioned survey covering the whole block earns its keep. One independent report on the leak’s location and cause gives every owner the same evidence, so nobody can argue the split was guesswork.
Got a leak the factor needs evidence on
We work with factors and owners across Scotland to pinpoint the source of a leak in common pipework, without opening up walls or floors unnecessarily.
Why factors commission leak detection reports
Before a factor authorises an expensive repair to common pipework, most will commission an independent leak detection survey first. Common repairs in a tenement can run into thousands of pounds once scaffolding and reinstatement are added to the plumbing itself. A factor who instructs that spend without solid evidence is exposed if an owner disputes the bill later.
A proper survey does two jobs. It confirms whether the fault is genuinely in shared pipework or sits inside one flat, which changes who pays entirely. And it gives the factor a written, insurance-approved report for the buildings insurer, the contractor, and any owner who wants to see the basis for their share.
Non-invasive methods matter to a factor’s decision
Non-invasive detection, using thermal imaging, acoustic listening equipment, or tracer gas, finds the leak without breaking into walls speculatively. For a factor weighing owners’ disruption against a contractor’s day rate, that matters. Our own water leak detection service finds the source first, so the factor can make an informed call.
When a factor is slow to act
Factors manage dozens of buildings at once, and a leak that isn’t an emergency can sit in a queue longer than any owner would like. Water coming through a ceiling is urgent. A slow seep damaging a common wall over weeks is the situation where owners most often feel stuck, watching damage spread while nothing visible happens.
Under One Roof, the tenement advice service, sets out a clear protocol: work out whether the source is an individual flat’s pipe or something common, check the title deeds, and notify insurers of what’s technically called an escape of water. If the leak comes from a common pipe or the roof, owners should claim on the block’s common buildings insurance where one exists. Where an owner or a factor won’t act, escalate.
Left unrepaired, a common leak compounds. Damp spreads into neighbouring flats and the repair bill grows. Reporting the leak in writing, with a dated record, protects your position if the repair is delayed.
The escalation path, step by step
When a factor is dragging their feet, or one owner won’t cooperate, there’s a recognised order of steps rather than an argument in the close.
1. Confirm the source and the responsibility
Establish whether the leak is common or private, and check the title deeds. A written report from an independent survey settles this if there’s any doubt.
2. Notify your insurer
Tell your buildings or contents insurer about the escape of water. If it’s a common pipe, this may fall to the block’s shared policy rather than your own cover.
3. Notify the factor in writing
Put the report and your request for action in an email or letter rather than a phone call. This creates the paper trail the escalation route relies on.
4. Escalate to Environmental Health
Where a factor or an owner still won’t act, Under One Roof recommends escalating to the council’s Environmental Health team, who can intervene where a property causes a nuisance.
What a factor cannot do
It helps to be clear about the limits, since owners sometimes expect a factor to have powers it doesn’t have. A factor cannot enter a flat without the owner’s permission, cannot force payment beyond normal debt recovery, and cannot compel a reluctant owner to allow access.
This is where the gap between a factor’s role and a statutory body’s power matters. Per Citizens Advice Scotland, Scottish Water can send a warning letter and obtain a warrant from a Justice of the Peace to force entry after 24 hours, repair it, then bill the owner. A factor has no equivalent power.
What a factor can do
- Instruct surveys and repairs to common pipework
- Apportion costs per the title deeds or Tenement Management Scheme
- Claim on the block’s common buildings insurance
- Pursue unpaid invoices through debt recovery
What a factor cannot do
- Enter a private flat without permission
- Force an owner to allow access for repairs
- Decide cost shares outside the deeds or statute
- Compel instant payment from a reluctant owner
Trace and access cover is worth understanding too. Price-comparison service Confused.com notes it pays for finding a leak and accessing it, including lifting floors or cutting into walls, and for making good the damage that search causes. It does not cover repairing the pipe itself, and commonly runs up to around £5,000, usually included as standard in buildings insurance.
Getting a survey moving without the wait
If your factor has agreed a leak needs investigating but the timeline feels open-ended, you don’t have to wait on their contractor list. Any owner can instruct an independent survey. That evidence speeds things up, since the factor no longer needs a diagnostic visit before briefing a repair contractor.
The Association of British Insurers estimates that escape of water costs insurers about £1.8 million in payouts every day, which shows why insurers expect a clear report before settling a claim. A same-day survey gets that evidence to the factor quickly, whether the leak is common or private.
Don’t let a small problem become a big one
Whether you’re an owner waiting on your factor or a factor needing evidence before instructing repairs, we can survey the block and hand over an insurance-approved report the same day in most cases.
Frequently Asked Questions
No. The factor arranges and instructs the repair, but owners pay for it collectively. Costs are split per the title deeds, or the Tenement Management Scheme where the deeds are silent, and the factor invoices each flat its portion once the work is done.
No. A factor’s authority covers common parts of the building, not the inside of a private flat. They can request access and escalate concerns, but cannot compel entry or force repairs. That kind of enforcement sits with bodies like Scottish Water or the council, not the factor.
Put your report in writing with dates, so there’s a clear record. Tenement advice service Under One Roof recommends checking title deeds, notifying your insurer, and escalating to the council’s Environmental Health team if the factor or a responsible owner still won’t act.
Usually the block’s owners, split the same way as any other common repair cost, since the survey is part of establishing and fixing the fault. Some blocks recover this through the buildings insurance policy under trace and access cover, subject to its terms and limit.
Check whether the pipe serves only your flat or several. A supply pipe feeding just your kitchen is usually your responsibility; a stack serving multiple flats is common. An independent survey can confirm the exact route and source when it isn’t obvious from the damage alone.
Yes, any owner can commission an independent survey, particularly if the source is unclear or the factor’s timeline is too slow. Having that report in hand often speeds up the factor’s process, since they no longer need a diagnostic visit before briefing repair contractors.
Often, yes, through the block’s shared buildings policy if a common pipe or the roof is the source. Water damage is usually covered as standard, and many policies include trace and access cover, commonly up to around £5,000, though not the pipe repair itself.
