Job description

We are looking for an organised and personable individual to carry out high level energy assessments for small businesses in Surrey. You’ll need a basic understanding of how to improve sustainability through energy in buildings and the capability to learn quickly in the role. The role would suit someone looking to build experience and expertise in the commercial energy sector, with the potential to train as a Non-Domestic Energy Assessor.

‘Energy Check’ is a new project run by Zero Carbon Guildford (ZCG) as part of our Sustainable Business Network. Around 30% of Surrey’s emissions are from commercial premises, and whilst SMEs are agile, and can collaboratively make significant reductions in Surrey’s overall carbon footprint, they often lack the resource, knowledge and funding to take action. This project aims to support 30+ small businesses by providing high level energy assessments which give actionable recommendations to reduce energy use, bills and improve sustainability.

Zero Carbon Guildford is a Surrey-based charity tackling environmental challenges with practical, local solutions that make a real difference. From supporting energy efficiency in homes to monitoring water quality and reducing food waste, we’re helping to make Guildford and Surrey greener, healthier, and fairer places to live.

This role is part of the Community Energy People project, funded by the National Lottery.
