International CSR Excellence Award
A Silver Award this week at the Green Apple Environment awards in London is wonderful recognition for the environmental improvements driven by Rosh Engineering. The Green Apple Environment Awards aim to recognise, reward, and promote environmental best practice around the world.
An example of our commitment to environmental best practise is the adoption of Greenovoc water based industrial paint that dries in an hour at temperatures as low as 6oC. No other paint delivers the protection and has the versatility and the environmental benefits. It is increasingly recognised throughout both the power industry and industry more widely.

Purchase of JMD Engineering Profiles Ltd. And the creation of Rosh Fabrications
The purchase of the neighbouring JMD Engineering means Rosh Engineering now has its very own Fabrication Shop, providing bespoke fabrications for Rosh’s own site operations and direct to all our customers. Rosh can now inspect, design, manufacture, paint, and install almost all its customers’ needs in house.
Rosh Fabrications follows ISO 9001, 14001 and 45001 ensuring the quality of our products, environmental management and the health and safety of our workers.
Northern Powergrid has adopted the innovative, environmentally friendly Greenovoc Speacility Coating for all its transformers and HV plant painting after carrying out trials with Rosh Engineering. The industrial paint dries at temperatures as low as 6oC in under an hour. A unique attribute for a water based zero VOC industrial paint.
Rosh Engineering Awarded ISO45001 Standard for Health & Safety
Great achievement for Rosh Engineering to have been awarded the new ISO45001 standard for Health & Safety which supersedes the OHSAS18001 which we have held for more than 12 years. Both OHSAS18001 and ISO45001 share a common goal: to reduce workplace injuries, illnesses, and deaths. The biggest difference between the two standards is how they approach that goal. Specifically, the new ISO45001 standard emphasises a more holistic approach to safety risk management — one that is integrated into an organisation’s core business processes.

Appointment of Project Engineer Bob Salsbury
Bob Salsbury joins the growing team at Rosh Engineering as project engineer. Bob brings enormous experience within the power industry having most recently worked for Scottish & Southern Energy (SSE). Bob will be managing a number of power transformer repair and refurbishment projects within the electricity supply industry as well as for large industrial customers. Customers in the Rosh Engineering portfolio stretch throughout the length and breadth of the UK, Ireland, Northern Europe with plans to expand further afield. Based out of Rosh Engineering’s Blaydon on Tyne factory Bob joins as the works expand increasingly into the renewable energy sector with large numbers of transformers being returned for off-site refurbishment to compliment the on-site capabilities of the business.
The founder of Rosh Engineering, Roy Dormer died on 9 April aged 91. He had just lived as many years as he could and it was not COVID-19 related. Having left school at 15 he went to night school to further his qualifications before joining Brush Transformers Ltd in 1950. On becoming Chief Test Engineer and Quality Manager his love of transformers grew into a passion. His work led to the discovery of where the hottest spot on a transformers active part really is through to thermal design work that resulted in changes to the American standard. He later became MD of a transformer cooling manufacturing plant in the North East before starting Rosh Engineering in 1981. Even into his 80s he loved nothing more than helping young engineers at Rosh, sharing his wisdom and love of the grey boxes that quietly hum and too many just take for granted.
