Affinity Trust

Affinity Trust is a values-led not-for-profit support organisation with national impact, where finance plays a central role in supporting sustainable, high-quality services for people with learning disabilities, autism and complex needs.

## Interim Senior FP&A Manager

**Location:** Thame (Oxfordshire) with hybrid working (minimum, 2 days per week in the office) and occasional travel

**Contract:** Interim, Fixed Term Contract until 31 March 2027

**Salary / day rate:** £60,000 per annum (pro rata)

**Reports to:** Head of Finance

### Role Overview

Affinity Trust is looking for an experienced Interim Senior FP&A Manager to bring senior finance capacity, challenge and insight across a complex, multi-site organisation.

This is not a routine reporting role. We are looking for someone who can quickly get under the skin of operational performance, understand the financial drivers behind service delivery, and help senior leaders make better, faster and more informed decisions.

You will work closely with the Head of Finance, Finance Business Partners, Divisional Directors and operational leaders, providing high-quality analysis, forecasting, commercial insight and constructive challenge. The work will span income, workforce costs, agency and overtime spend, utilisation, fee rates, contract performance, forecasting assumptions and recovery planning.

This is a senior individual contributor role, adding experienced capacity where it is most needed, to help maintain pace across key priorities, and strengthen the link between financial insight and operational action.

### The Assignment

You will be joining at a point where strong financial planning, clear analysis and senior business partnering are critical to supporting sustainable services.

Your work will include:

- Leading robust forecasting and scenario modelling across a complex operational portfolio
- Providing senior finance business partnering to divisional and operational leaders
- Analysing key cost drivers, particularly workforce-related costs such as agency, overtime, sickness and staffing ratios
- Reviewing income, fee rates, local authority funding assumptions, utilisation and contract performance
- Supporting tenders, contract reviews, business cases and service sustainability analysis
- Helping identify whether financial pressure is driven by fee levels, operational delivery, workforce deployment or a combination of factors
- Translating complex financial information into clear insight, options and practical recommendations
- Supporting the head of finance and wider finance team with additional senior capacity during a period of increased demand

### About You

You will be a qualified accountant with ACCA, CIMA, ACA or equivalent, and substantial experience in senior FP&A, finance business partnering or commercial finance roles.

You will be confident working with senior stakeholders and able to bring both grip and judgement. You will know how to challenge assumptions constructively, explain complex financial information clearly, and turn analysis into action.

You are likely to have worked in a complex, multi-site or operationally demanding environment, where financial performance is closely linked to workforce planning, contract income, service delivery and operational decision-making.

### You Will Bring

- Strong FP&A, forecasting, modelling and management reporting experience
- Advanced Excel and analytical capability
- Credibility with senior operational and finance stakeholders
- Experience supporting budgeting, reforecasting, recovery planning and performance improvement
- The ability to work at pace, prioritise well and operate with a high level of autonomy
- A practical, commercial and solutions-focused approach

Experience in social care, healthcare, supported living, charity or not-for-profit settings would be helpful, but is not essential. Experience with Local Authority funding, high-volume staffing models, workforce cost pressures or interim turnaround environments would be particularly valuable.

### Additional Information

Please note, if you are successful, we may need to complete a Disclosure and Barring Service (Criminal Record) check at the relevant level for the role. This will be paid for by us.

    Affinity Trust Jobs - Interim Senior FP&amp;A Manager


Business Manager

At Affinity Trust we support over 1,000 people with learning disabilities across England and Scotland, helping them live as independently as possible. We've been supporting people with learning disabilities for more than 25 years. 

We are dedicated to supporting people with learning disabilities to live the lives they want to. Whether helping someone to live in their own home, providing opportunities to make new friends, or supporting people into work, we aim to ensure that those we support can live life to its fullest.

We support people with a range of needs, from those who need little support to people who require round-the-clock, specialist support. We have a strong track record of supporting those with more complex needs, including people who other organisations have not been able to support appropriately.

We are a growing, national charity. Underpinning our success is our belief that everyone with a learning disability has the right to an active and fulfilling life.

Many of the people we support have come from institutional settings. We have worked with them to transform their level of independence and often, as a result, their quality of life. 

Supported living is our main area of support and we are committed to offering this model to people with learning disabilities in preference to residential care homes.

National charity that supports over 900 people with learning disabilities across England and Scotland, enabling them to live as independently as possible.
