We now have an opportunity for an Electrical Supervisor to join our M&E Projects team across the South of England. You will oversee the installation, testing, and commissioning of electrical fire safety systems including fire alarms, emergency lighting, and associated systems across a range of residential and commercial sites. This is a field-based role and flexibility to travel across multiple sites is essential.

We are passionate about making a difference and obsessed with quality. Our goal is to build a world where every resident can sleep safely at night, knowing their home is 100% compliant.

• Quality and Compliance Management – Ensure all electrical works including fire alarm installations, emergency lighting systems, and associated electrical systems are completed to Harmony, BS5839, BS5266, and industry standards. Carry out timely checking of works on site and ensure accurate data input and record keeping throughout.
• Site Management – Oversee site set up and sign off, stock management, delivery of prelims, pre‑condition surveys, and post inspections to allow for final sign off by the Project Manager. Identify and flag variation opportunities to the Project Manager immediately.
• People Management – Resolve day to day issues, boost team morale, manage conflict, and identify resource requirements. Maximise the productivity and utilisation of colleagues and subcontractors on site.
• Quality Control – Ensure all electrical works are certifiable and compliant, delivered to both client and Harmony expectations. Carry out regular spot checks, record findings accurately, and ensure all certification and test documentation is completed correctly at each stage.
• Client Management – Attend pre‑start meetings and ensure the site is always tidy and representative of Harmony’s brand. Carry out onsite resident liaison where required and communicate works clearly to those affected.
• Communication – Provide regular progress updates to the Project Manager and weekly reports to the client. Attend calls as needed and agree reporting frequency with the Project Manager.
• Health and Safety – Implement Harmony's H&S policy across all sites. Induct new trades, ensure completion of all relevant H&S paperwork, deliver regular toolbox talks, and maintain a safe working environment through ongoing training and auditing.

• Proven experience in an electrical supervisory or senior trades role within fire safety or a closely related discipline.
• Hands‑on experience with fire alarm systems and emergency lighting installations, including testing, commissioning, and certification to BS5839 and BS5266.
• Experience running projects to time and on budget across multiple sites.
• Comfortable working flexibly across the South of England, with a willingness to travel as required.
• Strong understanding of relevant electrical regulations and compliance requirements.
• A strong problem solver who sees things through to completion.
• Ability to build and maintain good working relationships with clients, subcontractors, and colleagues.
• Proactive, confident, tenacious, and resilient.
• An ambassador for Harmony's values and behaviours on every site.

This is a chance to run live sites for one of the UK’s fastest-growing fire safety specialists – the kind of work where you can see what you’ve delivered at the end of every week and know it makes residents safer. At Harmony, we ask a lot — and we give a lot back. The hours are real, the standards are high and the work is demanding, but for those who show up, deliver and go the extra mile, the rewards follow.
