Oakrange Engineering Ltd


Our business has been providing technical equipment and onsite calibration to the automotive industry for the past 25 years. We are proud to include amongst our clients Jaguar, Aston Martin, Mercedes Benz, the VW Group and many more.

The "claim and blame" culture is having serious repercussions for dealers, their customers, their employees and the vehicle manufacturers. There is increased policing by the HSE, Trading Standards, the public and product liability insurers.

Our onsite calibration and electrical services are presented as sensible cost effective measures for your compliance and reassurance.

For our part, we are increasing our commitment to training and our work with manufacturers. We have also upgraded our qualification to ISO9001:2008, with accreditation by TÜV, to reflect our increasing work with European manufacturers.

Our work passes through over 2000 independent audits per year, we make no unsubstantiated claims, and we have factual evidence of our performance standards and therefore guarantee our work.

We have always worked at continual improvement for our clients; it is that commitment that ensures we maintain our reputation, and our service standards to you.

Periodic Inspection

(Required under the electricity at work Act 1989) fixed wire testing - is the testing of circuits contained within the fabric of your building. This includes the socket outlets, lighting and various other circuits. Our fixed wire testing and inspection service includes:

  • Periodic inspection Testing and documentation of all electrical circuits within the building.
  • Full certification of your building to IEE Wiring Regulations, 17th Edition.
  • Documentation of work presented on IEE standard reports to comply with legislative and insurance requirements.
  • All life threatening faults highlighted.

Where premises are recently acquired or facilities expanded, we also provide a survey and reporting service to ensure your operations are not compromised by poor electrical layout. For example, multiple compressors and/or multiple vehicle lifts should be on individual isolators to ensure any fault on any one item does not result in isolating all items.

We will advise according to legislation any improvements, requirements or recommendations which may be required. We will also advise the extent of material and labour involved to carry out such work by local contractors. We do not carry out the work, or otherwise compromise our independent advisory position.

"The abuse of electrical systems etc, and their lack of maintenance are major causes of fire and can also result in death and injury. We would draw your attention to the Electricity at Work Regulations 1989 which make requirements to ensure electrical installations and portable electrical appliances are safe in use."
