The Role:
Brook Green Supply (BGS) is a leading independent B2B energy supplier, delivering tailored energy supply and Net-Zero solutions to industrial and commercial consumers.
Reporting to the Head of Policy & Regulation, the Sustainability Manager will own sustainability across the business. The role combines operational and reporting discipline with customer-facing thought leadership, policy insight, and commercial product development.
Brook Green’s direct operational footprint is relatively modest, but its greatest impact is through the energy it sources, manages, and delivers for industrial and commercial customers. This role will help Brook Green move beyond supply by supporting customers to decarbonise, reduce emissions, and consume greener energy.
The Sustainability Manager will work closely with Policy & Regulation, Trading, Commercial, Business Development, and Marketing teams to shape Brook Green’s sustainability strategy, strengthen its market voice, and turn operational learning into practical customer insight.
Essential Functions of the Job:
Policy insight and thought leadership:
- Develop and lead Brook Green’s internal and external sustainability strategy, aligned to business priorities, customer needs, and market developments.
- Establish Brook Green as a credible sustainability thought leader through policy insight, customer content, webinars, and external engagement.
- Monitor sustainability policy developments and identify opportunities for Brook Green to influence policy in line with the interests of the business and its customers.
- Work with Commercial, Business Development, and Trading teams to develop sustainability propositions that help customers decarbonise, reduce emissions, and consume greener energy.
- Translate sustainability trends, regulation, and market signals into clear, practical insight for customers and internal stakeholders.
