Senior Project Planner in Harrow

Be part of one of the largest upgrades to the UK power network in decades — a transformative, high-value project that will shape the nation's energy future. We're looking for a Senior Project Planner to lead the planning and coordination of complex, critical works within the power sector. If you're passionate about technical delivery, safety, and managing large-scale infrastructure projects, this is your opportunity to make a tangible impact.

In this role, you'll take ownership of planning activities across a key section of this nationally significant programme — from pre-construction to handover. Your leadership will be vital in driving safe, efficient, and high-quality project outcomes.

• Develop and maintain compliant, robust project programmes aligned to the project's business objectives.
• Plan and sequence works using collaborative, efficient construction methodologies.
• Monitor programme performance, identify risks, and drive corrective action.
• Lead planning through tender, design, procurement, and construction phases.
• Collaborate with clients, stakeholders, and the supply chain to manage interfaces and timelines.
• Provide commercial insight into programme impacts, production rates, and sequencing.
• Engage with commercial, design, and delivery teams to build realistic, achievable plans.
• Prepare and present progress reports, trends, labour efficiencies, and mitigation strategies.
• Support continuous improvement across planning processes and systems.
• Mentor and develop junior team members, sharing planning best practices.

• Skilled in programme development from first principles – able to interpret drawings, perform quantity take-offs, apply output rates, determine durations, and logically sequence works.
• Confident communicator who can present complex programmes clearly to internal teams and external stakeholders.
• Experienced with planning software such as Primavera P6 and/or Asta Powerproject. Familiarity with Synchro, Navisworks, Power BI, or Asite is desirable.
• Strong contractual awareness, ideally with experience of NEC contracts.
• Engineering background preferred, with strong understanding of project lifecycle, including scope, schedule, cost, and quality management.
• Proven experience planning large-scale infrastructure or power projects, preferably substations and high-voltage works.
• Degree in Civil Engineering, Construction Management, or a related field. Chartered Membership of CIOB is desirable.

• Long-term stability on a high-profile national infrastructure project.
• Career-defining opportunity with visibility, responsibility, and real impact.
• Supportive, inclusive culture where your contribution is recognised.
• Exposure to a diverse, integrated supply chain and multidisciplinary teams — including structures, MEP, facades, and more.
