Finance underpins everything we do at B Lab UK. As we continue to grow the B Corp movement, the way we manage our resources, systems and financial insight matters more than ever. As Finance Manager, you’ll be at the heart of that work — ensuring strong financial operations, robust controls and clear reporting that enable our teams to make confident, values-led decisions.

This is a role for someone who enjoys combining technical expertise with collaboration and purpose. You’ll work closely with colleagues across the organisation, acting as a trusted finance partner while continuously improving how we plan, report and operate. In return, you’ll have the opportunity to help shape a financially resilient organisation that exists to use business as a force for good.

B Lab UK is part of the global B Corp movement, with the mission to inspire and enable people to use business as a force for good. Certified B Corps seek to redefine success in business by putting social and environmental impact on a par with profit. There are now over 10,000 B Corps spanning 102 countries and 160+ sectors, with many well-known brands including Patagonia, The Guardian, Giff Gaff and Divine Chocolate. 2,700 of those businesses are in the UK.

As Finance Manager, you’ll lead the day-to-day finance operations at B Lab UK, ensuring high-quality financial reporting, strong controls and effective oversight of transactional finance. Reporting to the Head of Finance, you’ll oversee our outsourced accounting service, manage our in-house Accounts Receivable function, and play a key role in budgeting, forecasting, audit and financial planning.

Working collaboratively as a strategic partner, you’ll help embed efficient and effective ways of working that support organisational growth, sustainability and impact.

What you’ll be doing

• Managing and liaising with our outsourced accounting service to ensure accurate and timely financial records.

• Overseeing invoicing, income collection and aged debt reporting.

• Preparing monthly management accounts, including analysis and narrative for budget-holders and the Leadership Team.

• Developing and maintaining financial procedures and controls to protect B Lab UK’s assets.

• Supporting financial planning, including budgeting, forecasting and financial modelling.

• Providing clear financial insight to support strategic and operational decision-making.

• Supporting the annual audit process and statutory accounts under Charity SORP.

• Line managing the Senior Finance Officer and Credit Controller, supporting their development and performance.

• Contributing to Finance & Operations projects, including systems and process improvements.

The kind of things we’re looking for…

• A qualified accountant (ACCA, CIMA or equivalent experience) who is committed to ongoing professional development and raising the bar in their practice.

• Strong experience preparing management accounts and confidently explaining financial information to non-finance colleagues in a clear, supportive way.

• Demonstrable experience establishing, improving and maintaining robust financial controls and processes.

• Experience of budgeting, forecasting and financial modelling, with an improvement-focused approach that looks beyond the status quo.

• A solid understanding of charity finance, including statutory accounts, VAT and audit processes (or the motivation and capability to develop this quickly).

• Proven ability to line manage and support a small team, bringing out the best in others and fostering collaboration.

• Strong communication skills, with the confidence and integrity to guide stakeholders through complex financial matters.

• An analytical, solutions-focused mindset, with experience developing systems or processes that help teams go further together.

• A clear commitment to justice, equity, diversity and inclusion, and to being a force for good through your work.

• A belief in the power of finance and business to contribute to a more just, inclusive and sustainable future.
