The Company

Gren is an infrastructure-led energy company building the next generation of local utilities across the Baltics and the UK.

We develop, own and operate energy infrastructure that helps deliver cleaner, more reliable and more affordable energy to businesses and communities. We're investing in long-term energy solutions that support the transition to a lower-carbon future.

The Opportunity We're looking for an Accounts Assistant to join our growing finance team and play a key role in supporting the business's day-to-day financial operations.

You'll join a small, close-knit team split across Glasgow and London. We work together regularly, with team meet-ups throughout the year and occasional travel to London. We operate a hybrid working model, with office-based working on Tuesday, Wednesday and Thursday, and home working on Monday and Friday.

This is a varied, hands-on role that combines core finance responsibilities with the opportunity to take ownership of important business processes. You'll be responsible for supporting accounts payable and receivable activities, processing financial transactions, completing reconciliations and helping ensure the finance function runs smoothly and efficiently.

In addition to supporting the day-to-day finance function, this role will take ownership of administering Government subsidy claims. Working closely with the Operations team to gather and validate data, prepare submissions, and manage claims through to payment. Using Excel to monitor timelines, submissions and receipts, you'll play a vital role in supporting business revenue, working capital and cash flow.

This role would suit someone who enjoys working in a fast-paced, high-performance environment, takes ownership, uses initiative and focuses on solutions rather than problems. You'll be highly organised, motivated, collaborative and tenacious, with a genuine pride in getting the details right.

• Build and embed subsidy claim processes, ensuring claims are accurate, timely and compliant


• Proactively follow up with Government bodies and counterparties to ensure payments are received on time


• Support month-end activities and provide general assistance to the wider finance function


• Identify opportunities to improve finance processes, controls and systems


• Document ways of working to support consistency, compliance and scalability as the business grows


• Provide general administrative support where required, including management of company mobile phones

The Person We're looking for someone who enjoys working with numbers, is proactive and has the persistence to see things through to completion.

You will bring:

• AAT qualification, part-qualified ACCA/CIMA status, or equivalent practical finance experience


• Experience across accounts payable, accounts receivable, reconciliations and general finance administration


• Strong attention to detail and a commitment to maintaining accurate financial records


• Good understanding of financial controls and working within a structured and compliant environment


• Strong Excel skills are essential, with the ability to work confidently with large datasets, trackers and financial information


• Experience using accounting software, with NetSuite experience an advantage


• Experience managing multiple priorities and delivering work accurately and on time


• A track record of using initiative, taking ownership of tasks and seeing them through from start to finish


• Strong communication skills and confidence dealing with suppliers, customers, Government bodies and internal stakeholders


• A proactive approach to problem solving and continuous improvement


• The ability to work independently while also collaborating effectively with colleagues

The following would be advantageous, but are not essential:

• Experience within the energy, utilities, infrastructure or renewable energy sectors


• Awareness of Government subsidy schemes such as RHI, ROCs or CfDs


• Experience working within a shared services, multi-site or private equity-backed business
