Principal Consultant – Utilities in Slough

Hoare Lea is a human-centric and planet-conscious engineering consultancy. We offer intelligent and sustainable solutions to complex design challenges for the built environment throughout the UK and further afield.

We provide a wide range of engineering and consultancy services, including acoustics, air quality, building services (MEP), fire, lighting, security and sustainability. Together, our highly skilled teams use technical expertise and problem-solving skills to bring buildings to life. We ensure that whatever the building, its design is outstanding, and its operations meet the needs of the communities it serves.

We are committed to providing an environment where everyone can realise their unique potential. In joining Hoare Lea, you will experience a business that enriches your knowledge, supports your wellbeing, and welcomes your individuality. You’ll have the opportunity to participate in our 9-day fortnight scheme, thriving community groups, varied social and networking events, and extensive professional and technical development schemes. We also offer an extensive benefits package, including private medical cover, an electric vehicle salary sacrifice scheme, stock options, and 25 days of annual leave (increasing with service), alongside flexible and hybrid working.

We’re looking for a Principal Consultant to join our Advisory & Advocacy (A&A) team, at the forefront of utilities, infrastructure, and the UK’s energy transition. A&A operates at the earliest stages of large, multi-phase developments, helping clients unlock infrastructure strategies, secure capacity, and de-risk delivery in constrained systems. This role bridges utilities consultancy and grid strategy. You’ll understand connections, diversions (OHL, HP gas and more), and infrastructure delivery. You’ll know how to unlock solutions where standard approaches fall short. We work across the full lifecycle: moving, protecting, and enabling infrastructure, while coordinating across architects, engineers, and other key stakeholders.

The primary areas you would be working in within the Advisory and Advocacy team are:

• Utilities & Infrastructure - Our team combines deep technical expertise with strategic insight to support clients in securing timely, cost-effective, and futureproof connections.
• Energy Economics - Achieving Net Zero Carbon is intrinsically linked to an energy transition that presents challenge and opportunity in equal measure.
• Grid Services - Supporting the transformation of the UK to an all electric nation, working in a challenging environment to get the best from our electrical network.

To be successful in this role you will need:

• A 2:1 degree or above in a relevant subject, with strong analytical thinking and an appetite for solving complex problems.
• Proactive and adaptable approach, with the resilience to navigate evolving project requirements and client needs.
• Enthusiastic about engaging with the challenges of decarbonisation, infrastructure delivery, and the transition to low-carbon energy.
• Proven experience in utilities, in a related infrastructure field, and/or grid codes and connection processes.
• Proficient in 2D/3D AutoCAD and/or Revit.
• Experience in running projects both independently and in a team environment.
• Comfortable challenging the status quo and exploring innovative utility solutions for new connections and diversions.

To apply simply complete a CV profile and submit your application. If shortlisted, one of our recruitment team will be in touch to arrange an introductory call to discuss the role and your experience in more detail. From there, successful candidates will be invited to attend a panel interview, either via Microsoft Teams or in person at one of our offices.

If there are adjustments or accommodations that we can put in place to help you participate and give your best at any stage of the recruitment process, please let us know.
