Category: Access Control

The access control decision you make today will shape your security for years to come. It’s worth getting it right.

Card-based systems and biometric readers each solve different problems. Cards cost less upfront, scale easily, and keep you clear of the data protection complexities that come with storing fingerprints or facial templates. But they can be lost, stolen, or quietly passed to someone who shouldn’t have them. Biometric systems eliminate that risk entirely – nobody can lend their fingerprint – though they bring higher costs and stricter compliance obligations.

For most commercial premises, the answer isn’t choosing one or the other. It’s understanding where each technology makes sense within your building, and how proper monitoring ensures you actually know when something goes wrong.

The Big Picture

Before diving into the details, here’s what matters most:

• Card systems give you flexibility and simpler compliance. They’re cost-effective, easy to manage, and don’t trigger the special data protection requirements that biometric storage demands.
• Biometric systems provide certainty about who entered. The credential can’t be shared, borrowed, or stolen – which matters enormously for high-security zones.
• Hybrid approaches let you match authentication strength to risk. Use cards for general areas, add biometrics where you need absolute certainty about identity.
• Monitoring architecture determines whether you find out about problems in real time or eight hours later. This often matters more than the reader technology itself.
• Martyn’s Law introduces new legal requirements for premises with a capacity of 200 or more people. Access control moves from operational choice to compliance obligation.

Martyn’s Law: Why This Matters Now

The Terrorism (Protection of Premises) Act 2025 received Royal Assent on 3 April 2025. You have roughly 24 months before it comes into force, which sounds like plenty of time until you realise how much preparation it requires.

The law creates two tiers of obligation. Standard Duty applies to premises accommodating 200-799 people and requires documented public protection procedures covering evacuation, invacuation, lockdown, and communication. Enhanced Duty kicks in at 800+ capacity and adds requirements to actively reduce vulnerability to terrorist attacks.

Your access control system becomes central to meeting these obligations. Controlled entry points enable rapid lockdown when needed. Audit trails document who was present during an incident. Real-time alerts to your Alarm Receiving Centre support coordinated response when seconds genuinely matter.

The Security Industry Authority will provide regulatory oversight, with powers to investigate non-compliance. When they review your preparedness, they’ll want to see documented procedures, commissioning certificates, maintenance records, and evidence of regular testing. These demonstrate you’ve taken security seriously from the outset – not scrambled to add it when the inspector knocked.

Why Monitoring Architecture Matters More Than You Think

Picture this scenario: a door lock fails at 2am. Nobody notices until staff arrive eight hours later. You’re not just dealing with a broken latch – you’re managing an uncontrolled gap in your security perimeter that’s been open all night.

Insurers will scrutinise this. Investigators will question it. If something goes wrong during those unprotected hours, you’ll be held accountable.

This is where proper system design makes the difference. We build access control with robust monitoring architecture so silent failures become immediate alerts. When a door is forced, held open too long, or registers multiple invalid PIN attempts, that information reaches your Alarm Receiving Centre or control room straight away – not when someone finally checks the logs.

Access control systems designed to meet recognised British Standards don’t simply record who entered. They actively alert you the moment things go wrong, converting potential security gaps into actionable intelligence.

Card-Based Systems: What They Do Well

Card access translates the monitoring principle into daily operations. Every tap creates a timestamped record. Every rejected credential generates an alert. Every door alarm triggers a response.

When a cardholder attempts entry after hours, your monitoring team knows immediately. When someone forces a door, the alert reaches them in seconds. This means faster incident response and better evidence capture when it matters most.

Scalability That Grows With You

Card systems excel at adapting to changing needs. We can add new doors, issue temporary contractor credentials, or revoke access centrally without touching hardware at every entry point. You get control that grows with your organisation rather than constraining it.

Integration with CCTV links footage directly to access events, supporting investigations and insurance claims with evidence that holds up to scrutiny.

Resilience When Things Go Wrong

Battery backup maintains door control during power cuts. Dual-path signalling keeps your monitoring connection alive even when primary networks fail. For sites requiring continuous coverage, this resilience isn’t optional – because security vulnerabilities don’t wait for convenient business hours.

Biometric Systems: The Trade-Offs You Need to Understand

Biometric readers promise something cards can’t deliver: certainty about who actually used the credential. A fingerprint can’t be borrowed. A face can’t be lent to a colleague. For areas where you need absolute confidence about identity, this matters enormously.

But the technology brings complications worth understanding before you commit.

Accuracy depends heavily on sensor quality and environmental conditions. Dirt on readers, poor lighting, extreme temperatures, and the quality of stored reference templates all affect performance. A poorly specified system generates frustrating false rejections during busy shift changes and locks out legitimate staff when conditions aren’t ideal.

When specifying biometric readers, ask your installer about the device’s declared False Acceptance Rate and False Rejection Rate, environmental suitability ratings, and how failed-match events are logged for review. These details matter more than marketing claims about convenience.

Data Protection Obligations

Biometric data falls into the special category under UK GDPR – the same classification as health records and political opinions. This triggers obligations that card systems simply don’t have.

You’ll need a Data Protection Impact Assessment before deployment, along with clear signage at every reader explaining what you’re collecting and why. Your system needs role-based access controls limiting who can view or export enrolment templates, because insider threats are real. You’ll also need defined retention schedules and secure deletion protocols when people leave your organisation.

Miss any of these requirements, and you’re exposed to regulatory action that can make security breaches look manageable by comparison.

How Monitoring and Escalation Actually Work

When a door is forced, or an invalid credential is presented, that event needs to travel through a documented chain: from the field device through your control panel, along a transmission path to an Alarm Receiving Centre desk, where a trained operator interprets it and acts according to your specifications.

Your event alerts depend on threshold settings. Three failed swipes might trigger a desk alert for investigation. Forced-door signals or duress codes warrant immediate escalation – potentially to emergency services depending on your response protocols.

Operators follow established processing protocols, consulting your escalation tree, keyholder hierarchy, and site-specific instructions. Responses match your actual risk priorities, not generic templates.

Bi-directional communication ensures silent failures don’t leave you blind. Regular health checks between the operator and panel, conducted at defined intervals, catch developing problems before they become incidents.

We work with you to map these alert priorities and handoff procedures before commissioning, ensuring your monitoring architecture matches your risk profile rather than forcing you into off-the-shelf solutions.

Choosing the Right Technology for Each Zone

The choice between cards and biometrics shouldn’t be all-or-nothing. Most premises benefit from matching authentication strength to what’s actually at risk in each area.

Cards work well for general office access, visitor management, and areas where credential sharing poses minimal risk. They’re cost-effective, user-friendly, and avoid the data protection complexity of biometrics.

Biometric authentication makes sense for server rooms, chemical stores, data centres, and anywhere you need certainty that the authorised person – not just their card – actually entered. The higher cost and compliance overhead are justified when the stakes are high enough.

Hybrid approaches give you both. Card-plus-fingerprint dual-factor authentication verifies what someone holds and who they are. This is particularly relevant where your risk assessment justifies higher assurance levels.

When incidents occur, biometric logs tie individuals to events with certainty. Card logs only confirm a credential was present – not whether the authorised holder actually used it. This distinction matters when investigations happen.

Getting the Installation Right

A compliant installation starts with the installer’s certification, not the equipment brand. NSI or SSAIB accreditation confirms the company has been independently audited, maintains calibrated test equipment, employs properly trained technicians, and operates under quality-management oversight that catches problems before they reach your site.

Your access control system should be designed and installed in accordance with relevant British Standards – including BS EN 60839-11-1 for access control equipment, which establishes requirements for system design, event logging, and integration capabilities. These standards ensure your installation meets recognised best practice rather than improvised configurations that might underperform when tested by real incidents.

Documentation That Protects You

We provide commissioning certificates declaring conformity to the relevant standards, logs of door-hardware integration testing, and proof that event thresholds have been verified under real-world conditions. These documents support insurer requirements and provide an audit trail when incidents arise and questions get asked.

They’re also increasingly important for Martyn’s Law compliance. The SIA may request documentation showing your access control procedures and vulnerability reduction measures. Commissioning certificates and testing logs demonstrate you’ve implemented appropriate security measures – not just claimed you have them.

Maintenance: Your Insurance Against Silent Failure

A maintenance contract ensures logs remain intact, access rights stay current, and authentication devices function reliably when you need them. Defined response times, annual inspections, and remote health checks keep your system performing as designed.

Without proper maintenance, you risk silent failures that leave you exposed and incomplete evidence when incidents occur and your duty of care gets scrutinised. This isn’t a nice-to-have – it’s the difference between systems that actually protect and systems that create false confidence whilst vulnerabilities quietly develop.

Before You Go

You now have the framework to choose confidently and the questions to ask that reveal whether you’re getting genuine expertise or sales pitches.

Start by mapping your high-risk zones – server rooms, chemical stores, data centres, anywhere the consequences of unauthorised access justify stronger authentication. Consider your Martyn’s Law obligations if your premises accommodate 200 or more people, and factor these into your specification from the outset.

When requesting quotes from NSI or SSAIB-certified installers, ensure event-log integration, fire-alarm override, and annual maintenance are included as standard rather than optional extras that get value-engineered away later.

Don’t wait to retrofit monitoring architecture when your next security review demands it. Specify the audit trail, reader technology, and ARC integration your operations require today – because bolting on compliance after installation always costs more than getting it right first time.

Access control shouldn’t be an afterthought. Yet for many businesses, it’s exactly that – a system that’s been bolted on, patched up, or left to limp along because “it works… sort of.”

But here’s the thing: poor access control isn’t just inconvenient. It costs your business time, money and sometimes even its reputation. And those costs? They’re often hiding in plain sight.

Let’s explore how ineffective access control quietly undermines your business – and how upgrading it can be simpler (and more valuable) than you might think.

The Real-World Costs of Poor Access Control

When access control systems are outdated or poorly managed, problems creep in. Not necessarily all at once – but gradually, persistently and expensively. Downtime and disruption from lost keys, shared fobs and forgotten codes leave staff locked out and frustrated, or worse – let unauthorised individuals in. Without the ability to track entry, you face a serious challenge if theft, damage or compliance investigations occur. Productivity takes a hit too, as your team spends time chasing access or navigating clunky, manual systems. Older systems are often easier to bypass and provide little in the way of alerts or fail-safes, increasing security gaps. Non-compliance with fire safety or data handling regulations can lead to fines or reputational damage. And above all, the cumulative stress of dealing with all this wears down the people managing it day-to-day.

Additionally, the cost of constant maintenance or emergency call-outs to fix access-related problems adds up quickly. Whether it’s replacing lost keys, reprogramming entry points or chasing missing audit trails, every reactive task drains both time and budget. For larger sites with multiple entry points or rotating staff rosters, the admin overhead alone can become a full-time job. Even for smaller businesses, it’s a consistent distraction – one that undermines focus and interrupts smoother operations.

Spotting the Warning Signs

There are some clear indicators that your access control system isn’t pulling its weight. If your team is still managing access with physical keys – and no one is quite sure who holds which – or if entry relies on shared fobs or access codes that never change, it’s time to reassess. You might not have digital logs of who went where and when, or you’re struggling to restrict access to sensitive areas like server rooms or stock areas. Lost fobs might be a regular headache, and in some cases, your system may be running on outdated, unsupported hardware or software. Add in any recent security incidents – or close calls – and you’ve got all the signs of a system overdue for replacement.

Another subtle clue is when staff start finding workarounds – such as propping doors open or passing fobs between colleagues – because the system is too rigid or unreliable. These workarounds, whilst well-intentioned, undermine the very point of having access control in the first place. They introduce security risks and often go unnoticed until something goes wrong. In some cases, these behaviours also increase your liability in the eyes of insurers or regulators.

What Modern Access Control Looks Like

Access control has evolved – fast. Today’s systems offer smart, secure and user-friendly solutions, often using mobile credentials, biometric authentication, or programmable fobs. You can assign custom permissions, track real-time activity and manage access remotely from cloud-based platforms. Integration with other security systems, like CCTV or intruder alarms, ensures comprehensive protection. And crucially, you can phase upgrades in over time, minimising disruption whilst keeping security front and centre.

Modern systems are also more responsive to how people work today. Hybrid work, flexible schedules and multiple contractors all demand a system that allows quick updates to access privileges. Temporary passes, scheduled entry permissions and instant revocation all help reduce risk whilst maintaining operational flexibility. And because everything is logged automatically, audits become less stressful and far more accurate.

The Standards That Matter

When upgrading or installing access control, it’s not just about the kit. It’s about compliance. Several key standards and regulations must guide your decisions. BS EN 60839 defines performance and design standards for electronic access control systems. Any system that logs user data must also comply with GDPR and the Data Protection Act 2018. Fire safety regulations require access systems to fail-safe in emergencies and not hinder evacuation. And finally, NSI or SSAIB certification ensures you’re working with installers who follow best practice in design, installation and maintenance – so you don’t have to second-guess the system’s reliability. As a fully accredited provider, we follow these best practices in every installation we undertake.

Compliance isn’t a box-ticking exercise either. For insurers, proving you have the right systems in place – and that they’ve been correctly installed and maintained – can have a real impact on your premiums. For larger premises, or those with high-value stock or sensitive information, many insurers often insist on specific standards. Meeting these from the outset makes renewals easier and reduces the chance of claims being denied due to inadequate security infrastructure.

How to Upgrade Without the Headaches

Worried that upgrading your access control will mean weeks of disruption and confusion? It doesn’t have to. Here’s how we manage the process:

1. Site Survey: We assess your current system, security risks and staff movement patterns.
2. Tailored Design: We select access control points and permissions based on your needs, not off-the-shelf assumptions.

We design systems to meet compliance requirements and plan installations around your operations to minimise downtime. Your staff receive straightforward training to ensure the system is used correctly and confidently. And with our ongoing support in place, the result is a secure, efficient and compliant system that works as hard as your business does – without constant tinkering or stress.

Upgrades can often be phased, especially on larger sites. This means you can start with the most critical entry points or areas and roll out new infrastructure gradually, with minimal operational impact. We’ll help you create a roadmap that spreads out costs and avoids overwhelming your internal teams. And once the new system is up and running, the reduction in support calls and admin hassle often pays for itself within months.

Before You Go…

If you’re still dealing with poor access control – keys going missing, people getting locked out, permissions that are hard to manage – then it’s time to consider what it’s really costing you.

And more importantly, how much smoother life could be with a reliable, compliant, modern system that just works.

Because when access control is done right, it’s one less thing for your Responsible Person to worry about.

If you manage a venue or publicly accessible space in the UK, you’ve probably heard a lot about Martyn’s Law (also known as the Protect Duty and the Terrorism (Protection of Premises) Act 2025). For many, the prospect of new legislation brings a mix of anxiety and confusion, especially when it comes to what’s actually required to stay compliant. As an access control supplier, we talk to venue owners and managers every day who are worried about what Martyn’s Law means for their business, their staff, and the people who visit their sites.

The good news? While Martyn’s Law does introduce new expectations around security and preparedness, it’s not about forcing everyone to install expensive, high-tech systems or follow a one-size-fits-all checklist. Instead, it’s designed to help you take proportionate, sensible steps to keep your venue – and the people in it – safer from terrorism and major threats.

What Does Martyn’s Law Actually Ask of You?

Martyn’s Law applies to publicly accessible premises that can accommodate 200 or more people at any one time. If your venue meets this threshold, you will be legally required to comply. But what does that mean you need to do?

The heart of Martyn’s Law is about understanding your risks and being ready to respond. Rather than prescribing a set of technical solutions, the law asks you to look at your venue through a security lens: Where might you be vulnerable? How could someone exploit your entry points or crowd flows? What would you do if the worst happened?

In practice, this means carrying out a risk assessment, making sure your staff are trained for emergencies, and putting reasonable, practical measures in place to manage those risks. For a small community centre, that might mean simple procedures and regular drills. For a stadium or concert hall, the expectations – and the solutions – will naturally be more robust.

Crucially, Martyn’s Law doesn’t demand that you adopt specific technologies like multi-factor authentication, biometrics, or cloud-based systems. The law is flexible and proportionate: it’s about doing what’s reasonable for your particular situation, not ticking boxes or investing in unnecessary tech.

While Martyn’s Law officially passed in April 2025, it includes a two-year implementation window. This means your venue must be fully compliant by 2027. However, proactive planning now will save time and stress later.

How Access Control Can Support Your Compliance (and Your Peace of Mind)

So, where does access control fit in? While you’re not legally required to install any particular system, modern access control can be a powerful tool in your security toolkit. Imagine being able to quickly see who’s on your premises, restrict access to sensitive areas, or lock down parts of your site at the touch of a button. These capabilities don’t just help you manage day-to-day risks – they can make a real difference in an emergency.

Take visitor management, for example. Even a simple sign-in process – digital or paper – can help you keep track of who’s on-site, which is invaluable if you ever need to account for people during an evacuation or incident. For larger venues, electronic systems can provide instant reports and support your risk assessments by showing patterns or potential vulnerabilities over time.

Access control can also play a key role in your staff training. Including access procedures in your emergency drills helps ensure everyone knows what to do if they need to secure the building or guide people to safety. And when it comes to demonstrating compliance, having clear records of your processes and reviews can show that you’re taking your responsibilities seriously.

Best Practice Features: Going Beyond the Minimum

Of course, some venues want to go further than the legal minimum – especially if they face higher risks or simply want to set the gold standard for safety. This is where advanced access control features come into play. Things like multi-factor authentication, biometric entry, real-time monitoring, and integration with emergency services can all add extra layers of protection.

It’s important to remember, though, that none of these features are mandated by Martyn’s Law. They’re best practice options, not legal requirements. For some venues, investing in these technologies makes sense; for others, simpler measures are perfectly adequate. What matters most is that your approach matches your risks and resources.

Data security is another area where best practices and legal compliance overlap. While Martyn’s Law doesn’t set specific rules for data protection, the UK’s GDPR regulations do. If you’re collecting or storing information about staff or visitors, you’ll need to make sure your systems are secure and your data handling is compliant.

What Should You Do Next?

If you’re feeling overwhelmed, you’re not alone. The key is to start with your risk assessment – look honestly at your venue, your operations, and your people. From there, think about the practical steps you can take to make your site safer, whether that’s tightening up entry procedures, improving staff training, or considering an access control solution that fits your needs and budget.

And remember: Martyn’s Law is about being prepared, not about buying the most expensive technology or following a rigid template. It’s about showing that you’ve thought carefully about your risks and taken reasonable, proportionate action to manage them.

The UK Government’s detailed Section 27 guidance, which will provide final compliance criteria for Martyn’s Law, is expected in late 2025. Until then, businesses should follow interim advice via ProtectUK. A good place to start is the Free e-learning on ProtectUK

As highlighted in the recent Martyn’s Law webinar, be cautious of unofficial training providers using misleading endorsements or imagery. Until the Section 27 guidance is officially released, most legitimate training resources are available free from the ProtectUK platform.

Effective compliance also requires collaboration between access control providers, fire & security system installers, venue managers and local authorities. A joined-up approach ensures realistic and resilient security planning.

As also discussed in the Martyn’s Law webinar, public expectations around venue safety are increasing. Attendees are more likely to question visible gaps in security. For example:

• Why wasn’t that bag checked at the entrance?
• Why are those fire exit doors open and unattended?
• How come no one stopped that person tailgating?

We’re Here to Help
