Vacant and void properties are one of the most overlooked security risks in the UK. Whether your property is sitting empty between tenants, awaiting redevelopment, or caught in a legal process, an unoccupied building is a prime target for thieves, vandals, squatters, arsonists, and fly-tippers.
At Guard Mark Security, we provide professional vacant property security services and void property protection across the entire UK. With over a decade of experience and more than 500 properties secured, our SIA-licenced officers, 24/7 CCTV monitoring, and scheduled inspection programmes give property owners, landlords, and developers complete peace of mind from day one.
One call is all it takes. Your empty property could be protected within 24 hours.
Why Vacant & Void Property Security is Essential
Unoccupied buildings face a unique set of risks that occupied properties simply do not. The moment a property becomes vacant, the threats begin:
- Theft and metal theft: Copper piping, lead, electrical fittings, and fixtures are regularly stripped from empty buildings.
- Vandalism and criminal damage: Without a visible security presence, vacant properties become easy targets for opportunistic vandals.
- Squatting: Over 22,000 squatters illegally occupy commercial properties in the UK each year — and evicting them without legal support is costly and complex.
- Arson and fire risk: Unoccupied buildings are at significantly higher risk of fire, whether accidental or deliberate.
- Fly-tipping: Empty sites attract illegal waste dumping, which carries legal and financial liabilities for the property owner.
- Insurance invalidation: Most UK vacant property insurance policies require weekly inspections. Failure to comply can void your policy entirely.
The consequences of ignoring these risks can be devastating: costly repairs, delayed sales or developments, legal complications, and the loss of your insurance cover when you need it most.
Did You Know? Weekly Visits May Be Required by Your Insurer
Most UK insurance policies require vacant properties to be visited at least once a week. Failure to comply can invalidate your policy — meaning your insurer may refuse to cover losses caused by theft, vandalism, fire, or flood. Our scheduled inspection service keeps your property fully compliant, so your coverage remains intact.
Types of Vacant & Void Properties We Secure
Guard Mark Security provides vacant and void property security solutions for a wide range of property types across the UK, including:

- Residential properties and houses between tenancies or during probate and estate management
- Development and construction sites during planning delays or phased construction works

- Housing association and local authority void properties during decants, relocations, or demolition programmes
Whether your property is a single vacant flat or a large multi-site commercial portfolio, we have the experience and resource to protect it.
Our Vacant Property & Void Security Services
We deliver a comprehensive range of empty property security solutions, fully tailored to the size, location, risk level, and insurance requirements of your property.
1- Scheduled Property Inspections
Our SIA-licensed security officers carry out regular inspections on agreed dates, tailored to your insurance requirements. During each visit, we conduct thorough checks of the interior and exterior, including all doors, windows, locks, and access points.
We check for signs of forced entry, water damage, damp, pest activity, and any maintenance issues that could escalate into a costly problem.
Inspection frequency can be set at daily, weekly, or bi-weekly intervals — whatever your insurer demands and your risk level requires.
2. Interior & Exterior Security Inspections
Every visit includes a thorough inspection of both the interior and exterior of your property. Our team checks for signs of forced entry, broken locks, damaged windows, and any evidence of trespassing or vandalism on the outside.
Inside, we look for pest activity, water leaks, electrical issues, and any other risks that could compromise the safety or structural integrity of your property.
3. Detailed Inspection Reports
After every visit, you will receive a comprehensive written report within 24 hours. The report covers all areas inspected, any issues identified, their level of urgency, and recommended actions.
This gives you a clear and documented record of your property’s condition at all times — essential for insurance purposes and peace of mind.
4. Utility Meter Readings
Unauthorised use of gas, electricity, or water in vacant properties is more common than many owners realise. Our officers take meter readings during every visit and include them in your inspection report, so you can quickly identify any unexplained usage and take action before costs escalate.
5. 24/7 CCTV Monitoring & Emergency Response
Our SIA-licensed CCTV monitoring officers keep a watchful eye on your property around the clock. If a threat is detected — whether it’s a break-in, fire, gas leak, or any other emergency — our team responds immediately and alerts the appropriate emergency services to minimise risk and damage.
6. Keyholding Services
Guard Mark Security holds a secure set of keys to your property, enabling our team to carry out scheduled inspections and respond rapidly to emergencies — without you needing to be on-site. Our keyholding service also ensures your property remains compliant with insurance requirements and accessible to authorised personnel at all times.
7. Flexible & Customised Security Packages
No two properties are the same, which is why we don’t believe in one-size-fits-all solutions. Whether you have a single vacant unit or a large portfolio of properties across the UK, we will visit your site, assess your security needs, and build a package that works for you — from basic weekly inspection plans to full multi-site management with CCTV installation.

Frequently Asked Questions (FAQ)
Below are the most common questions our clients ask about vacant and void property security services in the UK.
How often does a vacant property need to be inspected?
Most UK insurers require vacant properties to be inspected at least once every seven days. Some policies may require more frequent visits depending on the property type and risk level.
Guard Mark Security can tailor your inspection schedule to meet your exact insurance requirements and provide written evidence of every visit.
What are the biggest risks to an unoccupied property?
The main risks to empty and unoccupied properties include theft (especially metal theft), vandalism, squatting, arson, fly-tipping, water damage from burst pipes or leaks, and insurance policy invalidation due to lack of inspection compliance.
Will my insurance cover a vacant property without regular inspections?
Most vacant property insurance policies require proof of regular inspections — typically weekly. If you cannot demonstrate that inspections took place, your insurer may reject your claim.
Guard Mark Security provides detailed written reports after every visit, giving you full documentation for insurance purposes.
Do you provide security services for a single vacant property?
Yes. We work with individual property owners as well as large portfolio managers. Whether you have one vacant property or one hundred, we will build a security solution tailored specifically to your needs.
What is the difference between a vacant property and a void property?
The terms are often used interchangeably. ‘Vacant property’ typically refers to any unoccupied building, while ‘void property’ is commonly used in the housing association and local authority sector to describe residential units that are empty between lettings. Guard Mark Security provides specialist security for both.
Can squatters be removed from a vacant commercial property?
Squatting in commercial properties is not a criminal offence in England and Wales, meaning the police cannot assist with removal.
Property owners must obtain a court order to evict squatters, which is both time-consuming and expensive. Preventing access in the first place through regular security patrols and CCTV monitoring is far more cost-effective.
How quickly can you start securing a vacant property?
In most cases, we can begin securing your vacant or void property within 24 hours of your initial enquiry. Contact our team today for a free assessment and rapid deployment.
