About Grayling UK
Grayling is one of the UK’s most connected communications agencies, helping brands, businesses and organisations navigate complexity, shape conversations and make a meaningful impact through smart thinking, cultural insight and creative ideas.
Our people are in equal parts exceptional professionals and wonderful human beings. We’ve been recognised as one of The Times and Sunday Times Best Places to Work 2026, reflecting the culture our people have built together across Grayling. It’s a culture grounded in trust, transparency, ambition and care, where talented people are empowered to do exceptional work while building meaningful careers.
We’re now looking for a Commercial Controller to join our Commercial Finance team and play an important role in the financial performance of our UK business.
The opportunity
This is a senior commercial finance role with the opportunity to work closely with leaders across Grayling's UK business, helping them understand performance and make well-informed commercial decisions.
You’ll take ownership of key areas of the UK P&L and lead our forecasting and budgeting processes, but this role goes beyond reporting the numbers. We’re looking for someone who can turn financial information into useful commercial insight – identifying risks and opportunities, challenging assumptions and helping leaders make better decisions around investment, resourcing and performance.
You’ll build trusted relationships with senior stakeholders across the business, combining strong financial judgement with the confidence to ask the right questions and provide constructive challenge.
What you’ll do
- Own key areas of the UK P&L, providing clear insight into performance and identifying emerging risks and opportunities.
- Lead UK forecasting and planning, partnering with Business Unit leads and senior stakeholders to develop robust assumptions and deliver accurate, timely forecasts.
- Lead the annual budgeting process, from planning and stakeholder submissions through to accurate delivery into Oracle EPM.
- Provide commercial analysis across areas including P&L performance, client profitability, staff utilisation and overhead spend, explaining the drivers behind performance rather than simply reporting the numbers.
- Partner with senior leaders on forecasts, proposals and business cases, providing insight and constructive challenge to support decisions around resourcing, investment and business performance.
- Support commercial and client contract decisions, working with Legal and other colleagues to identify and manage financial and commercial risks.
- Support effective cash flow management and work closely with Group Finance on month-end reporting and wider financial requirements.
- Make financial reporting easier to understand and more useful, helping colleagues outside Finance use financial information to improve performance.
- Build strong relationships across Grayling and become a trusted commercial finance partner to senior stakeholders.

- Strong Excel modelling skills and good PowerPoint capability.
- Strong organisation and attention to detail, with the ability to manage competing priorities and deadlines.
