Official Role Title: Senior Cost Manager – IT & Transformation (banking)

Location: London, Chatham or Wolverhampton – 3 days in the office

Salary: £75,000 – £85,000 + up to 25% bonus, pension + benefits

A well-established UK lender is looking for a Senior Cost Manager to take ownership of the cost agenda across both their on-premise IT estate and their cloud-native Transformation programme. It’s a role with real breadth covering budgeting, forecasting, performance reporting, and cost governance across a large and fast-evolving technology landscape.

This is a chance to step into a senior role that combines hands‐on financial ownership with strategic business partnering. You’ll lead the end‐to‐end cost process, from budgeting and forecasting through to cash accounting, capitalisation and depreciation. You’ll also be the key Finance voice within IT and Transformation, working closely with leadership to shape spend profiles, challenge plans, and tell a clear cost story that senior stakeholders can act on.

It’s not just about managing numbers – it’s about helping the business understand them. You’ll build driver‐based models, explain variances, identify cost‐saving opportunities, and make complex financial data accessible to both technical and non‐technical audiences. You’ll also play a central role in developing FinOps capabilities, simplifying models, and improving insight quality across the function.
