Switchgear control and maintenance

Place the care of your high and low voltage power equipment in safe hands.

Our extensive experience incorporating all types of HV equipment allows us to offer a maintenance package that is tailored specifically to your site requirements, all supported by a 24/7 emergency call out service.

As defined by the Electricity at Work Regulations 1989, owners or operators of HV equipment must ensure that their equipment is maintained and operated in a safe manner to minimise the risk of injury to personnel. Such management systems should include, but would not be limited to:

  • an appropriate safe system of work
  • policies and procedures covering the installation, commissioning, maintenance and operation of high voltage equipment
  • records highlighting the responsibilities and training requirements of personnel
  • an appropriate audit regime to monitor and maintain the effectiveness of procedures.

Our construction and maintenance team has HV authorised engineers, together with competent and experienced personnel to assist with substation inspections and planned switchgear maintenance. This ensures that your HV network is fully compliant with the relevant legislation, including the Electricity at Work Regulations 1989 and the HSG 230 requirement to keep electrical switchgear safe.
