Brook Green Supply • United Kingdom • Added on Sep 7, 2026
Apply →

As the new Sustainability Manager, you will serve as the central architect of the company’s environmental strategy, bridging the gap between internal operations and external market influence. You will lead the charge on Scope 1 and 2 reporting while simultaneously acting as a strategic consultant for commercial teams, ensuring that green energy products translate into tangible value for industrial clients.

This role is uniquely positioned at the heart of the UK energy transition. While managing the firm’s own footprint is essential, your primary impact comes from enabling massive industrial decarbonization through policy leadership and innovative supply solutions. You are not just reporting data; you are actively shaping the narrative of how a B2B supplier can accelerate a net-zero grid.

This suits someone who possesses a deep technical understanding of the UK energy market and thrives in a fast-paced environment where they can build a function from the ground up. You should be a persuasive communicator who enjoys translating complex carbon regulations into actionable commercial insights.

Job FAQs

What are the main missions and responsibilities of this role?

You will be the primary owner of the company's sustainability roadmap, balancing operational discipline with strategic thought leadership. This involves establishing a robust framework for Scope 1 and 2 emissions reporting, ensuring all carbon accounting is accurate and aligned with regulatory requirements like REGOs and ROCs. Beyond data, you are responsible for driving the commercial application of sustainability. You will partner with trading and business development teams to create decarbonization products that help heavy energy users reduce their environmental impact, effectively acting as an in-house consultant for both the business and its clients.

Key learning opportunities for this job

This role offers an exceptional vantage point into the complexities of the UK energy transition. You will gain deep expertise in energy policy, carbon market dynamics, and the specific regulatory mechanisms governing renewable energy certificates. As the lead for EcoVadis and potentially ISO certifications, you will master the nuances of global sustainability ratings. Furthermore, building a team from scratch provides high-level leadership and functional design experience that is rare in more established corporate structures.

How does the ideal candidate look like (experience, skills)?

The ideal candidate brings a potent blend of technical carbon accounting skills and commercial acumen. You should have a proven track record in the UK energy sector, with specific experience in ESG reporting frameworks and a clear understanding of the drivers behind industrial decarbonization. Soft skills are just as critical; we look for a credible communicator who can stand in front of brokers and C-suite stakeholders to explain market signals. Experience with EcoVadis, SECR, or Science Based Targets (SBTi) will significantly distinguish your profile.

Advice to stand out and make a successful application

To stand out, move beyond general sustainability concepts and demonstrate a nuanced understanding of the B2B energy supply landscape. Use your application to show how you would bridge the gap between reporting (compliance) and product development (growth). Highlight specific instances where you have translated complex regulatory changes into commercial opportunities. Brook Green is an agile, non-legacy business, so demonstrating an ability to work at pace and build structure where none exists will be highly valued.

What aspects of the company's sustainability is this role likely to focus on?

The primary focus is Scope 3 enablement; although you report on the company's modest direct footprint, the real work lies in the carbon intensity of the energy supplied to customers. You will focus on improving the transparency and 'greenness' of the energy mix. Additionally, there is a strong emphasis on governance and transparency. You will be tasked with elevating the company's external ratings and ensuring that claims regarding renewable energy supply are backed by rigorous data and policy alignment.

What are the main challenges someone in this role might face?

A significant challenge will be managing data integrity in a fast-moving energy market where regulatory goalposts frequently shift. You will need to maintain high reporting standards while the business continues to scale rapidly. Additionally, you may face the challenge of influencing external stakeholders and policy-makers to align with the interests of industrial consumers. Balancing the commercial drive for growth with strict sustainability commitments requires constant negotiation and strategic thinking.

How could a typical day look like for someone in this position?

Your day might begin by reviewing policy updates from Ofgem or government departments to assess their impact on current energy products. You might then shift to a meeting with the Trading team to discuss how carbon market fluctuations affect customer decarbonization strategies. Afternoons are often spent on content creation, perhaps preparing a webinar for brokers or refining the sustainability section of the annual report. You will also dedicate time to team management, guiding your colleagues through the operational steps of EcoVadis accreditation or office energy efficiency projects.

What are the opportunities for professional growth and development in this role?

As the business grows, this role is designed to evolve into a senior leadership position. You will have the opportunity to build and scale your own department, potentially expanding your remit into broader corporate strategy or dedicated policy advocacy. Success in this role places you at the intersection of finance, energy, and climate tech, providing a pathway to Chief Sustainability Officer (CSO) roles or specialized strategy consulting within the energy sector.

The main stakeholders you might be interacting with

Internal collaboration is broad, requiring daily interaction with the Head of Policy & Regulation, as well as the Trading, Marketing, and Business Development teams. You are the link that connects these functions to the sustainability agenda. Externally, you will be a key face of the company for B2B customers and energy brokers. You will also engage with industry bodies, regulators, and certification providers like EcoVadis to ensure Brook Green maintains its position as a market leader.
