What To Look For In A Vacant Property Security Provider

Whether it’s a block of flats or one of several commercial properties, a vacant property carries insurance requirements to meet, liability if someone’s hurt or a fire starts, and a condition to protect until it’s let, sold or redeveloped.

Your security provider can be involved in all three.

But choosing the right vacant property security partner is harder than it sounds, because most providers claim the same things on paper.

How To Judge A Vacant Property Security Provider Before You Sign

Asset managers, commercial landlords, housing associations and local authorities all run into the same difficulty when they compare quotes. The fairest test of any vacant property security company is what it can prove, which can be checked before anything’s signed.

Knowing the questions to ask your vacant property security provider gets you started and then it’s about following up and running your own checks, for example checking licensing, Approved Contractor Scheme (ACS) approval, inspection records, response times, difficult sites and mobilisation.

Licensed Officers You Can Check On The SIA Register

Every officer who guards a vacant property or holds its keys should carry a Security Industry Authority (SIA) licence. Security guard and key holder are both licensable roles. And there’s no need to take anyone’s word on it.

The SIA’s register of licence holders is public.

You can search it on GOV.UK using an officer’s 16-digit licence number, or their surname plus details like date of birth and security role. Ask each shortlisted provider for the licence numbers of the security guards they’d deploy to your site.

Licensing is only half the issue.

We’d also advise asking how officers are screened.

BS7858 is the British Standard code of practice for screening people who work in a secure environment and it’s the benchmark to expect for anyone given access to an empty property, since the people holding your keys are part of your security measures too.

Any professional security provider should be able to tell you who carries out its screening. At ProFM Group, every officer is SIA licensed and vetted to BS7858 (our screening runs through the National Screening Agency).

Then there’s asking who employs the officers on your site.

Some providers subcontract shifts, so it’s worth knowing whose SIA-licensed security personnel you’re relying on, and who answers for them if a security breach happens on their watch.

At ProFM, all our guards are employed directly, so you don’t have to worry about us subcontracting your site’s security.

ACS Approval & Accreditations That Match The Work

Officer licensing checks individuals.

ACS approval checks the company behind them, assessing the whole business (from staff training to financial management and health and safety) against a standard the SIA sets. According to the SIA’s own guidance for buyers, most approved contractors are scored against that standard every year, with independent assessors verifying the results.

You can confirm any provider’s status on the SIA’s register of approved contractors.

If a company describes itself as an ACS-approved security company but doesn’t appear there, that tells you what you need to know. That guidance also says approved contractors can only subcontract to other approved contractors, unless the SIA gives permission.

The same logic applies to every badge on a provider’s website.

We’d recommend checking that each certificate carries a current date, and that its scope covers the vacant property services you’re buying, since a provider can hold an accreditation for one part of its business and not another.

NSI Gold, for example, is relevant when you’re relying on CCTV monitoring and monitored alarm systems, because it’s an approval scheme for how security systems and their monitoring are delivered.

Inspection Records Your Insurer Will Accept

Your insurer judges your security largely on paper.

If you ever need to make a claim, you’ll have to show that the visits and property checks your policy required happened, and when.

Unoccupancy conditions vary from policy to policy, so check your own wording.

But as Insurance Business UK reported in October 2026, typical conditions for unoccupied buildings include internal and external inspections every seven days, with a log written at the time of each visit, ideally timestamped.

A usable inspection log should show:

• the date and time of each visit, recorded when it happened
• who carried out the inspection
• internal and external checks, including secure doors, windows, access control points and vehicle access
• photographs of the vacant building, timestamped in the provider’s own system
• any defects or signs of forced entry, and the action taken

Regular property inspections also catch slower problems — a leak, or rubbish piled against a wall that adds to your fire risks — before they become insurance claims.

We’d argue that record matters as much as the security patrols themselves.

ProFM Group’s regular inspections, patrol audits and detection reports come as standard.

They won’t guarantee a claim is paid (nothing can), but they answer most of what insurers ask about security at your vacant property.

Evidence of Response Times

The useful measure of a response time — the one worth comparing between providers — runs from the moment an alarm activates to the moment an officer arrives on site.

So ask who monitors your alarm systems, and when along with what the process is for despatching officers.

At ProFM Group, alarm monitoring runs from our National Operations Centre (NOC), a control room staffed around the clock.

Our VPOD units are visually verified, so an activation gives the NOC immediate notification with images, and operators can confirm unauthorised entry before anyone’s dispatched.

That cuts false call-outs, which means officers go to real incidents rather than a fox crossing the yard of a vacant building.

Our average alarm response time is 30 minutes across our contracts and locations.

Options For A Site With No Power Or Welfare Facilities

Plenty of vacant premises, from commercial units to empty buildings on industrial estates, have no mains power.

And many have no heating or working toilets either.

That rules out some physical security measures, but it shouldn’t mean going without site security.

A good provider of vacant property security will have more than one option for you.

ProFM Group’s VPOD alarms and mobile CCTV towers are solar powered (the towers give you temporary CCTV surveillance, with remote monitoring from our NOC).

Where a manned presence is needed, officers can be stationed in marked patrol vehicles. Steel security screens and doors, along with Heras fencing, deal with unauthorised access and forced entry without needing power at all, while our mobile patrols team can add scheduled vacant property security patrols on top.

How Quickly Cover Starts & How Easily It Changes

Look for a provider that starts every vacant property security contract with a site assessment, because without one, any proposal is guesswork.

Every ProFM Group mobilisation begins with one, so the physical security measures we propose reflect how your vacant property could be entered and what your insurer expects.

Speed matters too.

In our experience, empty buildings are at their most exposed in the days after they’re vacated, and we can put a physical presence on site the same day, usually within hours.

A vacant or void property rarely stays the same for long either. A tenant signs, demolition is scheduled or a refurbishment turns it into a construction site.

Your provider should scale cover up or down alongside the project, rather than tie you to a package built for day one, so your vacant property protection changes when your plans do.

Warning Signs Your Provider Isn’t Worth It

Whether you’re buying void property security for one empty property or a whole portfolio, most warning signs come down to missing evidence. Be cautious if a provider:

• can’t or won’t share licence numbers for the officers they’d deploy
• doesn’t appear on the SIA register of approved contractors
• describes itself as “number one” or “best in the UK” with nothing to back it up
• has no sample report from its vacant property inspections to show you
• gives a vague response time, or won’t say whether it’s an average or a guarantee
• won’t say whether officers are its own staff or subcontracted

Each makes your choice harder to defend to an insurer or a board, or makes it harder to trust that provider to keep your property secure.
