Every street light is cleaned and serviced every six years. The lamps in the units are regularly changed. A detailed electrical test is carried out at six-yearly intervals in accordance with the Institution of Electrical Engineer’s Regulations and a detailed structural inspection is carried out at every visit. All this work is carried out by the County Council’s Maintenance Contractor, currently SSE Contracting Ltd. To identify faulty lights night inspections are carried out on a monthly interval. Units requiring attention are noted and the Maintenance Contractor is instructed to carry out a repair.
