HV Installation

Specialists in high voltage installation and support services

Slaters Electricals are specialists in high voltage installation and support services. Our installation division primarily operates from a dedicated base in Sheffield, with additional skilled engineers based at our Head Office and main works in Newcastle upon Tyne.

Your high voltage assets should be installed to the highest standards to ensure safe and efficient operation and to manage Health and Safety risks. We are experienced industry leaders in this field having provided installation and cabling services for HV electrical equipment including transformers, switchgear and package substations across the UK since 1994.

Our site engineers include highly trained & qualified APs (Authorised Person) and SAPs (Senior Authorised Person) with extensive experience of testing and switching equipment up to 33kV. We are fully certified under all the major accreditation schemes including NICEIC, ECA, SafeContractor, Achilles UVDB Verify and ISO 9001 & 14001. We work in tandem with DNOs to ensure that all LV and HV assets are properly controlled and managed throughout site works, if necessary.

We regularly install HV equipment supplied by other companies. However, where possible, we recommend that clients use our full package HV solution to benefit from the efficiency and control of Slaters handling their complete project – from system planning and equipment supply, to installation and ongoing maintenance.

We also offer a specialist HV subcontractor service for main site contractors and building services contractors.
