About the role

We’re looking for a friendly, organised and proactive Finance Officer to join our small and welcoming team. This role is ideal for someone who enjoys working with detail, likes helping others understand finance processes, and wants their work to genuinely make a difference. This role is only being offered in a full time, permanent capacity.

You’ll be right at the heart of the organisation, supporting our finance and grants work and helping keep things running smoothly behind the scenes. The role is mostly home‑based, so you’ll need a safe and suitable space to work from. We’ll provide a laptop and phone, and you’ll spend at least one day a week with the team in our Leatherhead office.

If you enjoy variety, collaboration, and being part of a purpose‑driven organisation, this could be a great fit.

• Working with our external IT support when needed

• Contributing ideas to improve how we work across finance, HR, IT and office processes

• Getting involved in team events and wider organisational activities

• Pitching in with other admin tasks as needed — we’re a small team and support each other

About you

You’re approachable, well‑organised and comfortable working with numbers and systems. You enjoy helping others, take pride in doing things accurately, and are happy juggling a range of tasks. You will be confident, with the ability to seek out and solve problems on your own initiative, whilst working within a supportive framework.

You’ll need:

• An AAT Level 2 qualification or equivalent hands‑on finance experience

It’s a bonus if you have:

• Confidence working with senior colleagues or Trustees
