Electrical Supervisor

Electrical Supervisor
Welwyn Garden City / Harlow | Data Centres | Permanent
£60,000 - £70,000
If you’re an Electrical Supervisor who wants to work on data centre projects without being stuck on one huge site for years, this is a good opportunity to take ownership across a number of technically important schemes.
You’ll be working across data centre projects in Welwyn Garden City and Harlow, with individual projects around the £1m mark. The work is expected to involve critical electrical infrastructure, white space upgrades, containment, LV power, structured cabling, security systems, controls interfaces, commissioning support and live environment coordination.
These are not basic commercial installs. They are fast-moving data centre projects where quality, sequencing, access, safety and communication all need to be controlled properly.
The role
You’ll be responsible for supervising electrical works on site, making sure labour, subcontractors and specialist installers are working safely, efficiently and to the right standard.
That means managing day-to-day site activity, checking progress against programme, coordinating materials, raising issues early and supporting the Project Manager with QA, reporting, snagging and handover.
You’ll be expected to walk the job, understand what is happening on site and keep control of the installation.
What you’ll be doing
Supervising electrical installation works across live data centre environments.
Managing electricians, subcontractors and specialist suppliers on site.
Coordinating containment, LV distribution, small power, lighting, structured cabling, security systems and controls interfaces.
Making sure works are installed to drawings, specifications, RAMS and project standards.
Checking progress, reporting issues and supporting short-term lookahead planning.
Managing permits, access, logistics, materials and site coordination.
Supporting QA checks, snagging, test sheets, commissioning records and handover documentation.
Working closely with the Electrical Project Manager, site team, client representatives and other trades.
Maintaining high standards around health and safety, housekeeping and quality.
Helping drive the job through to completion without letting standards slip.
What you’ll need
You’ll need experience supervising electrical works within data centres, commercial fit-out, M&E contracting, critical environments or technically demanding building services projects.
Data centre experience would be a strong advantage, but good electrical supervision experience from live or fast-moving projects will still be considered.
You should be confident reading drawings, coordinating labour, managing subcontractors and dealing with the practical issues that come up on site.
Experience with containment, LV power, structured cabling, security systems, BMS interfaces, testing, commissioning support or live environment works would be useful.
You’ll ideally hold SSSTS or SMSTS, ECS or CSCS, and have a strong electrical background.
The right person
You’re organised, hands-on and technically sharp.
You can manage the site team, keep people moving and spot problems before they become delays.
You do not need to be micromanaged. You know how to control a workface, keep standards high and communicate clearly with the Project Manager.
You’ll suit this role if you want responsibility, variety and exposure to data centre projects where the detail matters.
This is a good opportunity for an Electrical Supervisor who wants to work on technically demanding data centre projects with a salary of £60,000 - £70,000 depending on experience.
