Site Supervisor – Domestic Retrofit Projects (ASHP & Solar Installations)

We are seeking a hands-on Site Supervisor to support the delivery of domestic retrofit projects, primarily focused on replacing electric heaters with Air Source Heat Pumps (ASHPs) and installing solar PV systems in residential properties.

This role would suit a qualified electrician, gas installer, or similar tradesperson looking to step into—or who has recently stepped into—a supervisory role. A valid CSCS card is essential, and experience working on the tools in a domestic setting is highly desirable.

Key Responsibilities:

• Supervise operatives, subcontractors, and day-to-day site activities.
• Conduct site inductions, safety briefings, and toolbox talks, ensuring attendance is recorded.
• Monitor and enforce health and safety procedures in line with CDM 2015 and company RAMS and permit-to-work processes.
• Review and approve RAMS; issue permits for specific works as required.
• Display and enforce site rules and ensure welfare facilities are clean and operational.
• Undertake daily site safety inspections, including checks on waste management and general compliance.
• Support the Project Delivery Manager in coordinating work schedules and site activities.
• Manage site deliveries and logistics, ensuring minimal disruption to residents.
• Keep the Site File and project records updated.
• Ensure first aid provisions are in place and up to date.
• Lead daily briefings and accurately report incidents, including near misses.
• Liaise with internal teams and external stakeholders to address and resolve on-site issues promptly.
• Assist with external inspections (e.g., H&S inspectors) when required.

Experience and Qualifications – Essential / Desirable:

• Experience in domestic construction, ideally involving retrofits, heating systems, or renewables.
• A positive, proactive attitude with a willingness to lead by example.
• CSCS card (essential).
• Trade qualification (e.g., electrician, gas installer, heating engineer) – highly beneficial.
• Knowledge of health and safety requirements; SMSTS, SSSTS or equivalent qualification is a plus.
• Strong communication and organisational skills.
• Ability to read and interpret construction drawings and specifications.
• First Aid trained (preferred).
• Understanding of legal responsibilities, welfare standards, and environmental compliance.
