A mission to remove delays and restore productivity
For almost 40 years, Turnkey Instruments – a leading developer and manufacturer of industrial instruments – has been focused on researching, developing, and delivering accurate and user-friendly products, while consistently backing them with excellent customer service.
Today, Turnkey Instruments provides environmental monitoring instrumentation, brake testing, and vehicle compliance testing equipment to regulatory bodies, vehicle manufacturers, transport operators, and inspection or testing centres.
The Search for a Responsive IT Partner
When Turnkey Instruments started to look for IT support, the problem wasn’t the technology – rather, it was how the support was delivered. They had struggled to find an IT company that genuinely listened and reacted to their needs. Instead, everything felt impersonal. Logging issues through a portal slowed things down, and as a result, when problems cropped up while senior staff were off-site, progress stalled. Employees were left feeling helpless, waiting for issues to be resolved. Over time, IT was not supporting the business anymore – it was getting in the way.
Ultimately, what they really wanted was simple: an IT partner that listened, reacted quickly, and stayed ahead of the curve – without forcing people into systems that did not suit how they worked. That search came to an end when Layer 4 was launched.
A decision built on trust
Fortunately, thanks to an existing long-standing professional relationship, when Turnkey Instruments heard that Mark Hill was setting up Layer 4, the move came naturally. Years of trust, understanding, and collaboration had already laid the foundation for a strong partnership. As a result, Turnkey was confident that this would be an IT company built around people, not processes for the sake of it.
IT support without barriers
Reliability, responsiveness, and consistency were not optional; they were critical. From day one, the difference was clear. Instead of portals and queues, staff had access to real people who understood the business. Crucially, if an issue arose – whether someone was on-site or not – support was only a phone call away.
As issued occured, problems were dealt with quickly and calmly. Communication was clear. More importantly, rather than just fixing issues, Layer 4 focused on strengthening the overall IT environment, making it more robust and reliable for the long term.
Beyond the day-to-day IT support, Layer 4 also supplies us with our data SIMs for our customer environmental monitoring devices. These devices are used not only in the UK but also around the world.
Dave Brooks, General Manager, Turnkey Instruments said: “The staff know that if I am not on site, help is only a phone call away and it will be dealt with in a timely manner. As a result, thanks to Layer 4, our IT is now more robust.”
Confidence across the business
Today, the impact is felt across the whole team. Staff no longer feel stuck when something goes wrong. Instead, they know support is available, responsive, and proactive – even when key decision-makers are off-site.
As a result, the business now benefits from:
- Faster issue resolution
- Greater confidence in IT systems
- More resilient infrastructure
- A support partner that genuinely listens and reacts
Most importantly, IT now quietly does its job in the background – enabling the business to operate smoothly, wherever people are working.
