Case Study: How A&F Sprinklers Reduced Non-Negative Test Results by 90%

A&F Sprinklers Transforms Drug Testing into a Culture of Care

A&F Sprinklers Ltd (“A&F”) designs, installs, and maintains automatic fire sprinkler systems across the UK, delivering trusted solutions for over 40 years. Known for precision and a people-first approach, the company leads the industry in safety, innovation, and
operational excellence.

A&F’s commitment to wellbeing goes beyond fire protection. It shapes how it supports its workforce. From site protocols to drug testing, the company is setting new standards for what proactive safety looks like. It’s why A&F treats drug testing as a thoughtful system designed to protect its people.

“Our mission is to spearhead and pioneer the industry. We’re always looking for more efficient ways to do things…safer ways to do things. We pioneer health and safety here.”

Dan Clayton, Group HR, Compliance & ESG Manager

Their ethos is simple but powerful: measure twice, cut once. That mindset informs everything from engineering decisions to employee wellbeing. It’s why A&F approaches drug testing as a considered process designed to protect their people, not as a disciplinary measure. When they introduced active drug testing three to four years ago, the goal was to be proactive, using workplace drug testing as a deterrent to reduce risk, not as a punishment. Whatever the situation, people come first. Their ISO 45001 accreditation underscores that A&F delivers on its commitments.

The Challenges With Traditional Workplace Drug Testing

Before adopting Intelligent Fingerprinting, A&F relied solely on for-cause testing; a reactive method that didn’t align with their preventive mindset. Without a scalable solution, testing felt inconsistent and intimidating. It lacked structure, created uncertainty, and failed to reflect the company’s broader commitment to prevention and care. The approach made testing feel more like a consequence than a safeguard.

As the business grew, so did the challenges. Today, A&F employs 140 staff directly and works with more than 300 subcontractors across the UK. With teams spread across a wide range of sites and sectors, maintaining consistent standards became increasingly complex. They needed a system that could scale with them and reinforce their values at every level.

“One of the main things we do across all our sectors, whether it’s the office or a construction site, is routinely and randomly drug test all our employees and subcontractors.”

From Punishment to Protection: A Cultural Shift in Testing

A&F decided to introduce a routine drug testing programme and set out to build a system that reflected its values. Just as importantly, it needed something that could be deployed nationwide without disrupting operations. That’s what led the company to Intelligent Fingerprinting.

“The process is efficient, seamless, non-invasive, and portable, which is great for us because we have sites all over the country. It’s painless.”

Dan Clayton, Group HR, Compliance & ESG Manager

For Dan and his team, the goal was not only operational but also cultural. They set out to shift the perception of drug testing from punishment to protection, embedding it within a broader commitment to employee wellbeing. In many organisations, drug and alcohol testing carries a negative reputation, often viewed as a threat. A&F aimed to replace that stigma with a sense of shared responsibility for safety. This internal cultural shift helped make testing a routine part of operations, fostering trust and acceptance among employees.

Some staff were initially hesitant, influenced by misconceptions about the invasive nature of other testing methods and uncertainty over what drug testing would mean for them. The A&F team responded with education and empathy, taking time to explain the process and address individual concerns. Once employees understood how fingerprint-based testing worked, perceptions began to shift.

Intelligent Fingerprinting supported the rollout directly, with the Customer Experience Team working closely with A&F to tailor the implementation. They helped managers introduce the system in a way that felt personal, respectful, and aligned with company values.

“The support we got was phenomenal. The training guided us on how to approach each individual. We used that methodology to put our people at ease.”

Dan Clayton, Group HR, Compliance & ESG Manager

Today, fingerprint sweat-based testing is a routine part of life at A&F. It is woven into daily operations, embraced by the workforce, and seen as a practical way to reinforce shared responsibility.

90% Fewer Non-Negatives and a Workforce That Feels Protected

Since adopting Intelligent Fingerprinting, A&F has seen clear and measurable improvements in both safety culture and testing outcomes. The shift has not only changed how testing is done, it has changed how people feel about it. Alongside this cultural change came a significant operational result, A&F has seen a dramatic drop in non-negative results, creating a far safer workforce.

“There are two key results: One, our team is more appreciative of why we do it and it’s talked about more. Two, our non-negatives have dropped nearly 90% across the board.”

Dan Clayton, Group HR, Compliance & ESG Manager

The impact goes beyond numbers. The new approach has helped build a stronger sense of trust and wellbeing among staff and contractors. Employees now view testing as part of a broader commitment to their safety, not just a compliance requirement.

A reduction of that scale signals more than just improved compliance, it reflects a safer, more alert workforce. By increasing the frequency of random workplace drug testing, A&F has successfully used the process as a deterrent. Employees understand that testing is consistent and impartial, which discourages risky behaviour before it can impact safety. This proactive approach not only reinforces the expectation of a drug-free workplace but also helps A&F avoid dangerous incidents and the significant costs associated with them. Employees know they are coming into a safe environment and feel confident their employer is actively looking after their health, safety, and wellbeing.

The Intelligent Fingerprinting Solution

A&F recently transitioned to an employee-owned trust, reinforcing their commitment to transparency, shared responsibility, and long-term sustainability. This shift reflects their belief that when employees feel empowered and valued, the entire organisation thrives. As ISO 45001 accredited pioneers, A&F continues to grow with safety, wellbeing, and employee satisfaction at the heart of every decision.

Their journey offers a blueprint for other organisations looking to modernise workplace safety. By rethinking drug testing as a tool for care rather than control, companies can foster stronger teams, reduce risk, and build cultures that truly support their people.

A&F understands that safety isn’t just about tools. It’s about trust. By choosing a drug testing solution that prioritises dignity, speed, and discretion, they’ve built a culture where safety is proactive, not punitive.

“It’s about making sure people are safe and that other people are safe around them.”

Dan Clayton, Group HR, Compliance & ESG Manager

This approach proves that drug testing doesn’t need to be confrontational or stigmatizing. When delivered with empathy and clarity, it can strengthen relationships, boost morale, and reinforce a shared commitment to employee wellbeing. A&F’s success shows that rethinking workplace testing can lead to meaningful change.
