Contracting & Service
Sigma Engineers holds government electrical contractor approval. We take installations from drawing through inspector clearance to energisation — and then keep them running.
Service 01
Complete electrical systems up to 11 kV HT — cabling, earthing, lighting and power distribution, executed to drawing and handed over tested.
Service 02
Electrical installation drawings prepared and taken through Electrical Inspector approval, so energisation is never held up by paperwork.
Service 03
Erection and commissioning across electrical and process instrumentation for plants and utilities.
Service 04
Annual and comprehensive maintenance for environments where downtime is not an option.
Service 05
Consultancy and monitoring to bring down connected load, power factor penalties and running cost.
Service 06
Workshop and on-site repair for the rotating and static equipment that keeps a plant live.
Share a BOQ, a drawing or just a description of the load. You will get a worked quotation with makes, ratings and delivery.
