Premier Technical Services Group PLC (PTSG) is to provide vital lightning protection services for Transport for London.

The contract, signed with regular Tier 1 contractor Engie, involves 499 buildings at 109 sites in all. Engineers from the Group’s Electrical Services division will complete the annual maintenance of the lightning protection systems present on all buildings.

The Electricity at Work Regulations 1989 require that lightning protection systems are tested regularly in accordance with BS6651 or BS EN 62305. PTSG recommends that systems are tested at intervals of 11 inspection and testing months, meaning across a 12-year period, they will have been tested throughout every season of the year.

Transport for London is responsible for London’s network of principal road routes, for various rail networks including the London Underground, London Overground, Docklands Light Railway and TfL Rail. PTSG recently worked on another contract for TfL, having completed a hydrant testing contract for London Underground.
