At Kearney Group Diagnostics (KGD), we believe that every vehicle tells a story — and it’s our job to keep that story running smoothly. Based in Hemlington, our mission is simple: to deliver high-quality, reliable, and transparent vehicle diagnostic services for individuals, businesses, and fleets across the UK. Whether it’s a car, van, truck, or bus, our expert team combines cutting-edge diagnostic technology with years of hands-on experience to keep drivers safe, vehicles efficient, and businesses moving.

Our journey began with more than just a love for engines and electronics — it began with heart. Catherine Kearney, the inspiration behind our company name, was a woman whose kindness, strength, and dedication continue to guide everything we do. Catherine believed in hard work, honesty, and helping others — values that remain at the very core of Kearney Group Diagnostics today. Her spirit drives our commitment to providing exceptional service with a personal touch, ensuring every customer feels respected, valued, and cared for.

Over the years, Kearney Group Diagnostics has grown from a small operation into a trusted name in the automotive industry. We pride ourselves on offering a full suite of services including Car Diagnostics, Van & Light Commercial Vehicle Diagnostics, Truck & Bus Diagnostics, Fleet Services, and even an online shop that offers automotive accessories, CarPlay systems, battery trackers, and more. Customers can also book services directly through our online shop, blending convenience with top-tier automotive expertise.

What truly sets us apart is our people. Our technicians are not only highly trained but genuinely passionate about their craft. We don’t just read fault codes — we interpret them, understand the bigger picture, and provide practical, long-lasting solutions. Every diagnostic comes with a detailed report, explained clearly and honestly, so our customers always know exactly what’s going on with their vehicle.

We also understand how vital time is — especially for those who rely on their vehicles for business. That’s why we offer flexible booking options, including our Emergency Out-of-Hours Diagnostic Report service, available 24/7 for urgent needs. We’re here when you need us most — because breakdowns don’t stick to a 9-to-5 schedule, and neither do we.

At Kearney Group Diagnostics, we don’t see our work as simply fixing vehicles — we see it as keeping lives and livelihoods on the move. From local drivers to nationwide fleets, our mission remains the same: deliver precision, reliability, and care in every service.

Catherine’s legacy continues to live on through the dedication of our team and the trust of our customers. Every diagnostic check, every service, and every smile from a satisfied customer is a reflection of her values — compassion, commitment, and community.

Kearney Group Diagnostics — driven by expertise, powered by passion, and inspired by Catherine.
