Projects






Hardtech HV’s project capabilities have evolved to cover the full range of customer demand in the sectors we work in, from small remedial works defined in service through to multi million HV Systems for new developments.
As part of the System Engineering Group we apply the Systems Engineering methodology to all of our project works and that gives greater emphasis on early validation of our plans to ensure the implementation work runs seamlessly on site.
This structured approach to HV System projects aligns well with the statutory processes used within DNO and IDNO energisation requirements which allows us to move smoothly through the necessary pre-energisation gateways as an Independent Connection Provider (ICP).
Our in-house front line team allows us to ensure that the quality of every joint and termination on projects is treated with the same skill and care as the planning, design and equipment specification is in the back office team.
