About Us

Based in Essex, JW Gray offers a nationwide service for the design, installation, test and maintenance of lightning and surge protection and earthing systems.

Our design team is ATLAS accredited and all our engineers are NVQ qualified to industry standards. Our contracts department conducts an individual service to ensure that you receive the system that exactly meets the requirements of your site and that your installation is carried out to the highest standards.

All our engineers are CSCS card holders and have achieved either an NVQ2 or NVQ3 qualification in lightning conductor engineering, as well as holding an SSSTS qualification.

The Electricity at Work Regulations 1989 require that lightning protection systems are tested regularly in accordance with BS6651 or BS EN 62305. We recommend your system is tested at intervals of 11 inspection and testing months, meaning across a 12-year period your system will have been tested throughout every season of the year.

Part of PTSG – the UK’s leading specialist services provider

JW Gray operates as an independent company. However, we have the enormous advantage of being part of Premier Technical Services Group Ltd (PTSG). PTSG is the UK’s leading provider of specialist services to the construction and FM sectors. It operates five business divisions:

Nationwide Operations

The name Gray has been associated with lightning protection since 1835. We believe we are the oldest trading company providing lightning protection services within the UK and possibly even Europe. Our strong reputation has been achieved through the same professional approach to every contract, regardless of its size or value.

We are founder members of the Association of Technical Lightning and Access Specialists (ATLAS) and are also members of the Steeplejack and Lightning Protection Training Group (SLPTG). Quality and safety take priority above all else and as part of our in-house quality management system, we undertake a completion check on all our installations before hand-over.
