Trainee / Junior Energy Assessor (On-Site)

A fantastic opportunity has arisen for an enthusiastic and detail-oriented Trainee or Junior Energy Assessor to join our growing team. This is an excellent entry point for someone looking to build a long-term career in energy efficiency, retrofit, and building performance, contributing to meaningful work that improves homes, reduces carbon emissions, and supports the UK’s journey to net zero.

We are a small but growing, award-winning sustainability consultancy based on Gloucester Road, Bristol. We deliver retrofit, testing, and consultancy services across the UK, helping clients meet PAS 2035 and other sustainability standards.

This is a site-based role that will often involve overnight stays Monday to Friday across the UK. Applicants must be comfortable with regular travel and staying away from home during the week.

You’ll typically visit homes to carry out Domestic Energy Assessments (EPCs) and will gain experience in air tightness testing, ventilation testing, cavity wall inspections, and retrofit assessments. Accuracy, consistency, and attention to detail are essential - high-quality assessments form the foundation for retrofit and decarbonisation projects.

As you develop in the role, you’ll be cross-trained in complementary services, providing a clear path for professional growth within the company.

• Identify potential risks or anomalies during assessments and report them appropriately
• Keep up to date with industry guidance, tools, and assessment best practice
• Provide flexible support to other parts of the business as needed

• Retrofit Assessment (PAS 2035)
• Airtightness Testing (ATTMA L1)
• Ventilation Testing (Part F)
• Borescope / cavity wall inspections
