About the Role
As a Site Manager, you will take day-to-day responsibility for the safe, compliant and efficient delivery of retrofit and decarbonisation works across your assigned sites, ensuring all works are completed in line with programme requirements, quality standards, resident commitments and PAS 2030/2035 frameworks.
Working closely with the Project Manager and the wider delivery team, including Retrofit Assessors, Designers, Coordinators, Resident Liaison Officers and supply chain partners, you will lead site coordination, subcontractor supervision and quality assurance.

As the primary site-based lead, you will be accountable for health and safety, quality control, housekeeping, resident engagement and subcontractor performance. Your role will be key in ensuring sites are well managed, audit-ready and delivered to a high technical and customer-focused standard.
This is an 18 to 24 month fixed-term contract, with the potential for a permanent position depending on future workload in the area.

- Promote a positive site culture focused on safety, quality, professionalism and right-first-time delivery.
- Contribute to continuous improvement through lessons learned and feedback.
