Integrated energy specialists
By bringing together Optimi, Heighway Energy, Heighway Construction, and Heighway Plant, we provide four distinct areas of expertise – integrated into one seamless service. Our clients don’t have to coordinate multiple contractors or balance conflicting schedules. With Heighway Group, every stage is managed under a single, accountable delivery partner.
Our teams understand the infrastructure demands of the UK power sector and work closely to meet them – delivering safe, efficient, and cost-certain results from start to finish.

A market leader in high voltage jointing, mechanical integration, and electrical installations – delivering quality and compliance across all systems up to 400kV.
Civil engineering & groundworks
Specialists in HV compound civils, reinforced concrete foundations, ducting, and site access. Our team supports the power sector with safe and scalable groundworks expertise.
In-house plant & equipment hire
A dedicated in-house fleet including cranes, MEWPs, dumpers, cable drum trailers, and HIAB lorries. Fully certified operators ensure seamless site execution.
EHV & commissioning specialists
Experts in Extra High Voltage (EHV) systems, protection, and commissioning. Optimi manages the design, testing, and delivery of complex infrastructure up to 400kV.
Delivering fully integrated projects
Why hire four separate contractors when one partner can deliver it all? At the Heighway Group, our divisions work as one coordinated team – delivering end-to-end infrastructure solutions across the UK power and distribution network.
We begin by understanding the full scope of your project – technical requirements, delivery schedules, safety priorities, and budget constraints – and then build a clear, structured plan that aligns every specialist team to a common goal.
From first brief to final commissioning, we offer complete project clarity.
Consultation
We engage early to define your technical needs and operational goals, ensuring every decision made from day one leads to a more efficient and cost-effective outcome.
Planning
Our planning team scopes, sequences, and budgets every element of delivery, setting realistic timeframes and creating clear responsibilities for all involved teams.
Installation
With civil, mechanical, electrical, and plant services delivered by our in-house teams, we execute every installation phase with full coordination, transparency, and technical care.
Commissioning
We oversee the full commissioning process – from test preparation and system integration to energisation and post-commissioning support – all delivered to the highest safety standards.
A commitment to excellence, safety & innovation
At the Heighway Group, we work on critical infrastructure projects across the UK – projects that must meet the highest levels of performance, reliability, and regulatory compliance. Every decision we make is grounded in safety, guided by technical knowledge, and focused on results that last.
Excellence
Each division is staffed by experienced professionals with a proven track record in the energy sector. We apply rigorous quality control throughout every project, from material selection to final commissioning.
Safety
We operate with zero compromise on safety. Our teams follow strict protocols across all civil, mechanical, and electrical workstreams, and we continue to maintain an excellent safety record with no major incidents.
Innovation
As energy systems evolve, so do our methods. We embrace new tools, processes, and sustainable practices to improve efficiency, reduce emissions, and build the next generation of energy infrastructure.
Working with the best
Our clients trust us to deliver high-value, mission-critical infrastructure. From national grid operators to independent distribution network owners, we work with partners who demand reliability, accountability, and proven experience.
“Working with Heighway LTD made our project really easy to manage. Because they offer such a wide range of services, Heighway was able to take on the project in its entirety. This meant we had one point of contact, which saved us the headache of liaising with and attempting to coordinate several different contractors.”
– Jack Lonsdale, Project Manager
