Our Story

Who we serve is less important than how well we serve them

Who We Serve

For 30 years Pennine have provided first-rate calibration services to a variety of clients—all sizes and across many disciplines. Our first big customer was British Coal in 1985. Our largest by far now is HSE. We're proud to say we've been awarded their calibration contract on three successive occasions—the only company to have it since HSE began outsourcing their calibration and maintenance requirements in 1999. That should say something about how we serve as well.

  • Electrical & Electronics
  • Railway
  • Vehicle
  • Aircraft
  • Marine
  • Defence (inc MOD)
  • Utility Companies

We Go To Great Lengths For Our Customers

Siemens Power Generation came to us with a calibration requirement involving length measurements up to 6 metre—even beyond in some cases. We could not find a suitable subcontractor that measured up. So Pennine decided to create our own internal facility that did—centered around a SIP MUL 3000. We had to remove part of our building's external wall to site the 3.5 ton unit. But Siemens was delighted. And we couldn't be happier with our new dimensional laboratory for UKAS length measurement up to 3 metres.

How We Gave Life Jackets New Life

HSE recently replaced their life jacket fleet and we saw the opportunity to improve the service we provided. An audit of our sub-contractors had revealed weaknesses so we saw great benefit in bringing the routine servicing in-house. This would enable a quick turnaround and at a lower price so we contacted the manufacture and became approved as an official service centre. The new lifejackets have been getting along swimmingly ever since.


We Were Morrison PLC’s Answer To A Hire Authority

Morrison PLC found their way to being a large international building and maintenance company. But then they found themselves without suitable 17th Edition test equipment. So Pennine found it for them, albeit with one small catch. We had the equipment on hand—ready to hire—but were not an approved supplier. What to do? We agreed to hire the equipment without formal paperwork or an order number so we could help the customer in a critical emergency. Our flexibility led to formal supplier approval and the…well, founding of a long term relationship.

We Made HSEkit A Site To Behold

Health and Safety Executive asked us to host their certificates online and this was the beginning of a bespoke website that has developed rapidly to become an invaluable resource for HSE's equipment users. We added photographs of all equipment and instrumentation, their user manuals and certificates. There is a dynamic and growing user knowledge base and a customer support platform that provides an efficient base for dealing with routine and urgent support requests. Working closely with HSE we created a site to behold in a relatively short period of time. The site had to be attractive as well as functional so we now have a facility for photographing equipment to a high standard which together with professional design makes the site appealing and memorable. The customer found the end product and design content to be picture perfect.
