Retail and hospitality crime in the UK is at its highest level on record, and London businesses are absorbing a disproportionate share of it. The British Retail Consortium’s 2025 Crime Survey recorded more than 20 million theft incidents nationally last year, alongside a sharp rise in violence and abuse against staff. Against that backdrop, an increasing number of London businesses are reassessing whether their existing intruder alarm actually does what they think it does, because for a lot of premises, the honest answer is no.
An alarm that simply makes noise when triggered is only part of the picture. What actually determines whether an incident gets a meaningful response, police attendance, a keyholder alerted, evidence captured, comes down to how the system is specified, monitored and registered, not just whether it’s fitted.
The Standard Most Businesses Don’t Know Exists
Since June 2019, any monitored alarm system installed with the aim of securing a police response has needed to conform to BS 8243, the British Standard covering how alarm systems generate and confirm genuine alarm conditions before police are asked to attend. Without meeting this standard and being registered for a Police Unique Reference Number, a system simply won’t trigger a police response at all, regardless of how loud the siren is or how quickly the alarm actually goes off.
Qualifying for a URN also means the system must be installed by an NSI or SSAIB approved installer and connected to a properly listed Alarm Receiving Centre. A lot of London businesses, particularly those operating from older premises or relying on a system installed years ago, are unknowingly running alarms that don’t meet this standard, and would find that out only at the worst possible moment, when police response actually matters.
Why Older Systems Are Becoming a Bigger Problem
There’s also a practical deadline affecting a large number of existing systems. Legacy alarm connections relying on older telecoms infrastructure are being phased out, with providers increasing prices and switching off legacy services entirely. Businesses still running these older connections risk losing both police response eligibility and, in some cases, valid insurance cover, unless they upgrade to a modern, dual-path digital connection installed by an accredited provider.
For a London business that hasn’t reviewed its alarm system in several years, this combination, ageing infrastructure being withdrawn alongside record crime levels, makes now a particularly important time to check exactly what’s actually installed and whether it still qualifies for the level of response the business is assuming it has.
What a Properly Specified System Actually Provides
A genuinely effective business alarm system goes well beyond a siren on the wall. It should be monitored around the clock by a listed Alarm Receiving Centre, registered for police response where eligible, installed and maintained by an accredited installer to current British Standards, and integrated sensibly with other building security, CCTV and access control, so an incident triggers a coordinated response rather than an isolated alert that someone has to notice and act on manually.
London businesses reviewing their current setup, particularly those operating from premises with valuable stock, cash handling, or a history of previous incidents, should look into professional security alarm systems for business to establish whether their existing provision genuinely meets current standards or needs upgrading.
The Insurance Angle Businesses Often Miss
Beyond the direct security benefit, insurers are increasingly specific about what they expect from a commercial alarm system before offering competitive terms, or in some cases, before offering cover at all. A system that’s compliant, properly monitored and installed by an accredited provider isn’t just more effective at deterring and responding to crime, it can directly affect the cost and availability of a business’s insurance. A business relying on an outdated or non-compliant system may find this out only when a claim is challenged or a renewal comes back with unexpected conditions attached.
Don’t Wait for a Renewal or an Incident to Find Out
Reviewing an alarm system tends to fall down the priority list precisely because it’s working, in the narrow sense that it makes noise and hasn’t caused an obvious problem. That’s a low bar given what’s actually at stake. A system that’s quietly non-compliant, running on infrastructure being withdrawn, or missing police response eligibility altogether looks identical to a properly specified one right up until the moment it’s actually needed, and by then it’s too late to fix.
What London Businesses Should Do Next
Given how significantly retail and hospitality crime has escalated, reviewing an alarm system that hasn’t been assessed in years isn’t an unnecessary precaution, it’s a reasonable response to a genuinely changed risk environment. A few questions are worth answering honestly: is the current system registered for a Police URN? Is it connected through modern, accredited infrastructure rather than a legacy connection facing withdrawal? And was it installed and is it maintained by a properly accredited provider?

If the answer to any of those is uncertain, that uncertainty is worth resolving now, while it’s a planning decision rather than something discovered in the middle of an actual incident.
