Safety Approach

Safety is a priority that we set above all else within H&MV Engineering and we are uncompromising in implementing our health & safety policy.


Zero Lost Time Accidents Since Inception

Eliminating accidents

Eliminating accidents is our number one priority. All our projects need to be safe for both our staff as well as our customers.

Eliminating Down Time

Power outages can have serious consequences and this is why we have a well developed set of unique skills and quality procedures to eliminate down time.

What’s the key to achieve this?

Highly Qualified Staff

We pride ourselves in having the best skilled workforce in our industry. Our team is not only highly qualified, but are also constantly developing their skills to keep up with the newest technologies and safety requirements.

High Voltage Projects

Comprehensive Turnkey Services

We take you through the whole project – from project design stage to supply, installation and commissioning of 3.3 kV to 400 kV transmission and distribution networks, project supervision and management.


Extensive expertise in the design and build of contestable projects to Distribution Network Operators (DNO), Distribution System Operators (DSO) and Transmission System Operators (TSO) functional requirements.


Over the years we have established our quality system and procedures to ensure client’s projects are delivered to a high level of quality and exceed expectations.


Our dedicated team of qualified commissioning engineers – with over 20 years experience in the high voltage industry, ensure projects are on time and without risk by having all the necessary test equipment at their disposal.
