About Delta HV

Delta HV is a specialist high voltage electrical engineering and installation company, based in the South East and delivering projects across the UK.

We specialise in high voltage substation installations, upgrades and modifications for clients across both the regulated and private sectors.

With over 30 years of combined experience spanning engineering, project management, construction, installation and commissioning, our integrated teams provide a genuinely end-to-end service; on time, within budget and to the highest standards, with value engineering embedded throughout.

To strengthen our delivery capability, we established an in-house Protection & Control Panel manufacturing facility; originally created to support our own substation projects through greater quality control, programme certainty and supply chain resilience.

That capability has since evolved into a dedicated standalone service, supplying bespoke Protection & Control Panels to utilities, contractors and industrial clients throughout the UK.Our mission is straightforward; to work safely, efficiently and cost-effectively, delivering a complete solution and a quality end product for every client.
