From service callsto major projects.
CESS is a Sydney commercial service and project contractor supporting businesses, facilities and construction clients across Electrical, Mechanical Electrical, Data & Communications and Audiovisual.

One commercialcontractor.
Our work ranges from reactive service calls and ongoing commercial maintenance through to workplace upgrades, fitouts, refurbishments and larger project packages, for businesses, facility and property managers, builders and commercial clients across Sydney and NSW.
We don't compete purely on lowest price. We compete on professionalism, reliability, quality, communication and coordination — and on being the contractor that identifies issues early and takes responsibility for its scope.
Most relationships start with a single service call. The goal is to be the contractor you rely on, for the small jobs and the big ones.



Service you can rely on
Faults, repairs, alterations and upgrades across four core services, from the same commercial contractor every time.
Four core services, one team
Electrical, mechanical electrical, communications and AV delivered in-house, so fewer contractors to organise.
Technical problem solving
We test and investigate before recommending anything, and explain what we found and the options.
Project capability
Our team has experience working in Tier 1 environments, with SWMS, ITPs, as-builts and O&M manuals as standard.
We do whatwe say.
Safety
Planned and performed in line with legislation, Australian Standards and safe work procedures.
Quality
Compliant, organised installations completed to a high standard.
Reliability
Realistic commitments, followed through. Issues raised early, never hidden.
Communication
Clear, timely updates from enquiry to handover.
Accountability
We take responsibility for the work within our agreed scope.
Continuous improvement
Lessons from every job feed back into estimating, delivery and documentation.
The peopleon yoursite.
Licensed, ticketed and site-ready. The team that estimates your job is the team that coordinates it, installs it, tests it and hands it over — so there's always someone who knows the scope inside out.
