We’re at a big turning point at SGN.
The world is changing fast — expectations from customers,
communities, regulators and our stakeholders are rising. Technology is moving
quicker than ever. We need to catch up and then stay ahead if we want to be the
best GDN in the UK. We need to make sure we’re set up for success. We’re
already making great progress with a new CEO and Executive Team, a new COO
function and we’ve just moved from five to nine regions in our Southern
network, creating closer communities for our people. We’ve opened a Business
Services Centre, giving everyone easier access to the services they need,
and we’ve brought in 550 new vans, with hundreds more on the way.
But this is just the beginning. We’re focusing on three
big goals:
Supporting our frontline first
Cutting waste, not corners
Working smarter, together
We’ve already started work on a five-year programme that
will help us achieve our goals, and our journey will continue over the next 3-4
years.
We’re now offering fantastic opportunities
for colleagues to help us on this exciting journey.
The FSP / BPR Project Support role is responsible for
supporting the effective delivery of the Finance Simplification Programme (FSP)
and Business Process Review (BPR). Working closely with Programme and
Initiative Leads, the role ensures delivery activities are tracked and governed
effectively, enabling progress against time, cost, and quality objectives.
We deliver safety, warmth,
and comfort to homes and businesses. Every role, whether in the office or on
the front line, plays a key part in this mission. Here’s how you will
contribute…
Your Role and Impact
As
the Senior Portfolio Delivery Manager, you will be responsible for the
oversight and delivery of a complex portfolio of business programmes and
projects. You will work at the intersection of strategy, governance, and
execution—ensuring that transformation initiatives are aligned with corporate
objectives, risks are effectively managed, and benefits are realised.
Lead the strategic planning, coordination, and delivery of a portfolio of programmes aligned to business priorities.
Manage interdependencies, resource allocation, timelines, and budgets across the portfolio to optimise delivery and value.
Engage with senior stakeholders and executive sponsors to ensure alignment, resolve escalations, and drive decision-making.
Own and evolve portfolio governance structures, ensuring effective reporting, risk management, and benefit realisation.
Provide leadership and coaching to programme and project managers, supporting the development of best practices across delivery teams.
Monitor performance across the portfolio using key KPIs, providing insights and recommendations for improvement.
Act as a key partner to Finance, HR, IT, and other functions to ensure cross-functional alignment and integration of change initiatives
What You’ll Bring

Strong knowledge of portfolio and programme management methodologies (e.g. MSP, MoP, PMI, Agile-at-scale).
Exceptional stakeholder management skills with experience working at executive/board level.
Ability to navigate ambiguity, influence cross-functional teams, and drive clarity in complex environments.
Strong commercial acumen, with experience managing budgets, forecasting, and business cases.
Expertise in risk, issue, and dependency management across multiple concurrent programmes.
Experience in regulated or complex organisational environments (e.g., utilities, financial services, healthcare) is a plus.
Relevant professional certifications (e.g. MSP, MoP, PMI PgMP, Agile) are desirable

you but you’re not sure you tick every box, we’d still love to hear from you.
You might be just who we’re looking for – now or in the future and we have a
