About DNA
WE'RE EXPERIENCED, INDEPENDENT, AND COMMITTED TO DOING THE RIGHT JOB.
DNA is a Fife-based network infrastructure specialist providing design, installation, testing and technical support across Scotland and the wider UK.
Alastair Donaldson leads DNA, bringing over 30 years of hands-on industry experience.
The company was founded on a simple principle:
Recommend the solution the customer needs and deliver it the right way.
MEET ALASTAIR
Alastair Donaldson has spent almost three decades working across network infrastructure, structured cabling, fibre, wireless networking and connected security systems.
During that time, he has worked in defence, commercial, industrial, educational, and domestic settings. He has handled everything from simple installations to complex projects with unique building or operational challenges.
This means DNA considers each project without being limited to one product or technology.
Instead, Alastair looks at the full picture: how the building is used, what the customer needs, what infrastructure is already in place, and what will provide the most reliable, practical long-term solution.


WHY DNA?
Good infrastructure starts with good advice, personal service, and high professional standards.
Too often, customers get offered whatever a supplier happens to sell, but the real starting point should always be your needs.
Sometimes that means copper cabling, sometimes fibre or wireless, and often the best answer is a mix of technologies working together. What matters most is understanding which technology is right, where to use it, and why.
This is where DNA’s owner-led approach stands out. Clients get direct access to the expertise and decision-making behind their project, without going through layers of salespeople or account managers. When extra resources or specialist support are needed, DNA works with contractors, IT teams, facilities teams, and other professionals, while always keeping clear responsibility for the work we do.
In the end, customers get infrastructure designed for their building, business needs, budget, and long-term plans, not just a standard product. They also benefit from responsive service, deep technical experience, and the high professional standards of a specialist business.
HOW WE WORK
Expert technical help without the hassle.
Network infrastructure can get complicated. Our job is not to make things sound more complex. We explain what we recommend, why, and what it means for you in clear, simple terms.
We listen before recommending.
We begin each project with your needs, not our assumptions.
We explain the options.
If there’s more than one way to solve a problem, we’ll help you see the differences.
We don't overspecify for its own sake.
The most expensive option is not always the best choice.
We never cut corners just to offer a lower price.
Correct specification and professional installation matter.
We keep you informed.
Clear communication is built into every project, not added at the end.
We think beyond handover.
Your infrastructure should keep working well long after installation.
MORE THAN JUST CABLING
Expertise across different fields. A complete perspective.
Cabling is at the core of our work, but modern infrastructure usually goes beyond that.
DNA's experience spans:
Structured Cabling
Fibre Optic Networks
Wi-Fi Wireless Networking
Point-to-Point Wireless Links
CCTV & Video Survelliance
Access Control
Network Design
Testing & Certification
Project Management
Technical Support
Our experience in these areas helps us look beyond a single installation and understand how all parts of the infrastructure should work together.
For customers, this often means fewer suppliers, clearer accountability, and a solution built as a whole rather than in parts.
WHO WE WORK WITH
DNA supports customers across a range of environments, including:
No matter the environment, our approach stays the same: we find out what’s needed, recommend the right solution, and install it the right way.
