Testing & Commissioning
Even when the best possible approach has been taken, equipment will fail from time to time. If your equipment fails, we offer a fast responsive service to help you restore supplies as quickly and as efficiently as possible.

Whatever the fault, you can leave it entirely in our hands to resolve

At HVSS, we pride ourselves on offering impartial advice so that, during the fault process, you can identify whether to opt for an urgent / immediate repair or apply another strategy, such as installing a temporary generator.

Our teams will manage the system so that your electricity supplies are restored at the earliest possible opportunity.

In the case of a cable failure, we will organise teams to complete excavation and reinstatement of groundworks, we will co-ordinate the trade teams necessary to effect a repair and we will then test and commission the finished article so that your electrical network is restored to a fully operational state.

Whatever the fault, you can leave it entirely in our hands to resolve.
