An empty building is a liability that grows quietly. Most owners discover the scale of it only after something has already happened — a break-in, a burst pipe left running for weeks, or an insurer declining a claim over a condition nobody had read.
Here is what actually matters, roughly in the order it matters.
Start with your insurance policy
This is the step people skip, and it is the one that costs the most.
Most commercial property policies change substantially the moment a building becomes "unoccupied", usually after 30 or 45 consecutive days. Cover can narrow to fire and lightning only, and continued cover typically depends on conditions such as:
- Notifying the insurer in writing that the property is unoccupied
- Documented inspections at a stated frequency, often weekly or fortnightly
- Water, gas and electricity isolated at the mains
- Letterboxes sealed and the building secured to a specified standard
Read the unoccupancy clause before you do anything else. Every measure below is easier to justify once you know what your policy actually requires, and an undocumented inspection regime is the most common reason a claim fails.
Remove the reasons to break in
Opportunistic entry is driven by what is visible and what is rumoured to be inside.
Clear the building. Copper pipe, cabling, boilers, lead flashing and catalytic converters in an abandoned vehicle are all worth stealing. Metal theft causes damage far exceeding the value of what is taken — a stripped roof leads to water ingress that ruins a building in one winter.
Take out anything that identifies the previous use. A building that obviously used to be a pharmacy or an electronics unit attracts a different class of attention.
Deal with the appearance of neglect. Accumulated post, overgrown grounds, flyposting and unrepaired damage all signal that nobody is watching. Broken windows genuinely do attract more broken windows.
Physical security, in order of value
- Secure the perimeter first. Fencing or hoarding with no easy climbing aids. Most intruders enter at the back, away from the road.
- Harden the openings. Steel screens on ground-floor doors and windows, and on any window reachable from a flat roof, bin store or wall.
- Light it. Motion-activated lighting on approaches. Cheap, and it removes the cover intruders rely on.
- Isolate the services. Drain down the water system in particular. Escape of water in an empty building is one of the largest sources of loss, and it runs undetected for weeks.
- Remove climbing aids. Skips, pallets, scaffolding and wheelie bins left against a wall are a ladder.
Squatting: the legal position
This is widely misunderstood, so it is worth stating plainly.
Squatting in a residential building has been a criminal offence in England and Wales since 2012, under section 144 of the Legal Aid, Sentencing and Punishment of Offenders Act. Police can act.
Squatting in a commercial building is generally not a criminal offence. It is a civil matter, and removal means going to court for a possession order. That process takes time and money, during which you have no access to your own building.
Two practical consequences follow. First, prevention is enormously cheaper than removal — by the time someone is inside a commercial property, your options are slow and expensive. Second, do not attempt to remove occupants yourself: using or threatening violence to enter a property where someone is present and opposed to entry is itself an offence under the Criminal Law Act 1977. Take legal advice.
Where guarding fits
Physical measures deter the opportunist. They do not deter someone who has watched the building and knows nobody comes.
A visible security presence changes that calculation, and it also gives you the inspection record your insurer wants. What it should include:
- Patrols at irregular times. A predictable 9am visit every Tuesday tells anyone watching exactly when the building is empty.
- Written, time-stamped reports for every visit, with photographs. This is your evidence for both insurers and any future possession claim.
- Immediate escalation for signs of attempted entry, so a first attempt does not become a successful second one.
- Internal checks, not just a walk round the outside — water ingress and early squatting both show up inside first.
For long-term voids, guarding is often cheaper than the alternative once you account for a single escape-of-water claim or a contested possession action.
A short checklist
- Unoccupancy clause read; insurer notified in writing
- Water, gas and electricity isolated; system drained
- Valuable metals and identifying signage removed
- Perimeter secured; climbing aids cleared
- Ground-floor and accessible openings screened
- Motion lighting fitted
- Letterbox sealed; grounds maintained
- Inspection schedule running, with written records
- Keyholder and escalation contacts documented
If you have a property standing empty in Birmingham or the West Midlands and want a straight answer on what it needs, get in touch. We can usually have guards on site within 24 to 48 hours, and we will tell you if patrols are enough rather than selling you a static post you do not need.
