What our clients say
Trusted by engineers, researchers, and procurement teams in some of the world’s most demanding sectors.
“I would highly recommend RF Com Ltd as an excellent supplier to work with. I only wish all of our suppliers were as efficient, responsive, and helpful. We have been working with RF Com Ltd for a number of years, and they have consistently gone above and beyond to support our requirements. Whether we need price history on components or assistance sourcing hard-to-find parts, they always do their utmost to accommodate our needs, while remaining highly competitive on price. Their customer service is outstanding, and we can always rely on receiving a prompt response. It has been a pleasure working with them, and I would not hesitate to recommend RF Com to others.”
— Sharon McIlhone, Procurement, Leonardo
“RF Com just gets it. Finding suppliers who understand what a university research group needs — small quantities, fast turnaround, no minimum order headaches — is harder than it should be. RF Com are a genuine exception. Every technical question I’ve thrown at them has been answered properly, not with a copy-paste from a datasheet I’d already read. Quick, knowledgeable, and genuinely helpful.”
— Research Associate, School of Engineering, University of Glasgow
“It has been a pleasure working with RF Com over the past eight years. Their team consistently responds to RFQs promptly, provides regular updates, and maintains excellent communication throughout every stage of the procurement process. What truly sets RF Com apart is their willingness to go the extra mile. Whether sourcing hard-to-find components, identifying suitable alternatives for obsolete parts, or helping us establish reliable repair solutions, they have always been proactive, resourceful and supportive. Their transparency, responsiveness, and customer-focused approach have made them a valued supplier. We know we can approach them with any requirement, and they will always do their utmost to find the right solution. We highly value our long-standing relationship and would confidently recommend RF Com to any organisation looking for a dependable and knowledgeable supplier.”
— Natalie Hay, Project Leader, Leonardo
“The only supplier I’ve found in the UK who actually understands cryogenic RF. Sourcing components for a dilution refrigerator RF chain isn’t like normal procurement. RF Com understood the application immediately. The cryogenic isolators they recommended were exactly right for our qubit readout chain. Genuinely useful guidance, not just a product push. Fast delivery and solid technical support throughout.”
— RF Systems Engineer, Quantum Hardware Development Team
