Finance Business Partner - Opex

At National Grid, we keep people connected and society moving. But it’s so much more than that. National Grid supplies us with the environment to make it happen. As we generate momentum in the energy transition for all, we don’t plan on leaving any of our customers in the dark. So, join us as a Finance Business Partner, and find your superpower.

We’re looking for a confident and commercially minded Finance Business Partner to join our Electricity Transmission Finance team, supporting the Asset Operations function. This is a high impact role providing financial leadership across a c.£160m operational expenditure portfolio, driving performance, efficiency and strong financial discipline in a complex, regulated environment.

You’ll work closely with senior leaders across Asset Operations and Finance, influencing key decisions relating to operational performance, cost management, investment trade-offs and efficiency delivery. This role offers strong exposure, commercial breadth and the opportunity to shape financial outcomes across a critical part of the network.

This role is based out of our Warwick office, and we’d hope to see you at least two days per week, but you’re welcome to be in the office more often if that would work best for you. We’re happy to discuss any additional flexibility in working patterns or requirements that you feel could help to make this job work for you!

What You'll Do:

Act as the lead finance partner for Asset Operations, providing insight, challenge and decision support.
Identify and drive efficiency and productivity opportunities, embedding them into forecasts and plans.
Support regulatory and strategic decision-making, assessing cost, risk, reliability and consumer value trade-offs.
Own the performance narrative, translating actuals, forecasts, risks and opportunities into clear actions.
Lead month-end reporting, budgeting and forecasting, including variance analysis and business commentary.
Develop insight into key cost drivers (labour, contractors, maintenance, inspections, repairs and support costs).
Provide robust challenge to ensure forecasts are evidence-based and aligned to operational plans.
Ensure strong financial governance, including accurate Opex/Capex classification and audit-ready reporting.
Improve data quality, reporting and MI, enabling better, faster decision making across the business.

What You'll Have:

Fully qualified accountant (ACA, ACCA, CIMA or equivalent) or equivalent experience.
Strong commercial mindset with confidence to challenge and influence stakeholders.
Excellent stakeholder management and communication skills, with the ability to operate credibly at senior levels.
Experience working with large and complex datasets and driving insight-led decision making.
Strong understanding of financial governance, controls and risk.
A focus on what matters most to the business, making sure time and effort is going into the areas that will have the biggest impact.
trong experience in budgeting, forecasting, financial reporting and performance management.
Ability to translate complex financial data into clear, actionable insight.

Don’t meet every single requirement? Studies have shown that women and people of colour are less likely to apply for jobs unless they meet every single qualification. At National Grid, we are committed to building a diverse, inclusive, and authentic workplace for everyone. So, if you’re excited about this role but your experience or qualifications don’t match the job description exactly, we encourage you to apply anyway. You might just be the right person for our growing business in this role or another one.

What You'll Get:

Up to £77,000 dependant on experience

As well as your base salary, you’ll receive a bonus based on personal and company performance, a competitive contributory pension scheme, and access to a range of flexible benefits including share plans, salary sacrifice schemes and wellbeing support.
