Protect your private electrical networks from faults

Due to the reliability of high-voltage switchgear and transformers, regular servicing is often overlooked. The same can be said of the protective equipment that remains inactive until called into action. Not maintaining and taking good care of these assets or waiting for a fault to occur can be severely disruptive, dangerous and costly to a business.

At Serconnect, we provide a range of bespoke and flexible maintenance agreements and services for all clients to make sure your electrical infrastructure remains in perfect operational order and is legally compliant.

Regular maintenance is essential for all electrical infrastructure, as faults can occur at any time. Addressing minor issues early reduces the risk of costly repairs, downtime, and equipment damage further down the line.

Sites with their own substation or transformer must comply with key UK regulations, including the Electricity at Work Regulations 1989, BS 7671, and the Distribution Code, as well as guidance from the HSE and ENA. These standards not only ensure the safe operation, maintenance, and integration of high-voltage infrastructure with the wider electrical network, but are also essential for meeting insurance requirements.
