Leading the way in carbon capture infrastructure to ensure a sustainable future for the UK

At United Infrastructure, our team specialises in the design, construction, and maintenance of complex, critical infrastructure across the energy and pipeline sectors for high-profile industrial and commercial clients. We are leading the way in developing the UK’s first CO₂ pipelines by combining technical expertise with a strong commitment to social responsibility. Our approach ensures tailored solutions that deliver exceptional local and regional benefits while remaining cost-effective, compliant, and sustainable.

We provide full turnkey engineering, procurement, construction, and commissioning services. We combine self-delivery with the best the world can offer to ensure a best-for-task, best-practice solution that meets all project requirements. We deliver highly tailored services to match our solution to each project, client, and community in which we work. Our reputation is built on the delivery of complex, critical infrastructure projects, with a substantial history of undertaking complete design and construction responsibility. Our strength lies in managing highly specialised inputs from others, scoping needs, and leveraging our supply chain to fulfil component design and ensure construction is completed on time.

Our process

How we deliver

Appraise

This initial stage is predominantly carried out by authorities and regulators, working with developers, to assess the technical, environmental, safety and economic feasibility of proposed projects.

Select

We step in at this stage, to support activities that analyse and select potential site locations and route options, including geological, hydrogeological, geotechnical, and topographical studies. United Infrastructure provides consultancy support for pre-FEED, FEED, and early stakeholder engagement.

Pre-FEED

Refinement of conceptual designs

Completion of detailed surveys for pipelines

Stakeholder engagement and consultation

FEED

Detailed engineering designs

Equipment specifications

Refined cost estimates and project schedules

Early engagement for consenting, licences and permissions for key interfaces such as utilities.

Support for Development Consent Order (DCO) preparation

Initial environmental impact assessments

Preliminary consultation with local authorities and stakeholders

Define

At this stage, the project is further defined, with detailed documentation to develop the critical path for the project including long-lead items, organisational planning and project parameters, defining the technical requirements and estimating investment costs. United Infrastructure provides additional consultancy support for FEED finalisation and DCO process:

Finalisation of engineering designs

Ground investigations

Support cost estimates and project schedule development

Assess criticality of materials for long lead items

Challenge constructability drawing on our decade-long experience

Risk assessments and mitigation strategies

Support formal public consultations

Assist in preparing and submitting DCO applications

Completing Environmental Impact Assessment

Execute

We deliver UK-led solutions drawing on global best-in-class expertise, with a highly collaborative approach to ensure trust, strong relationships, and mitigated risks.

Achieving first of a kind projects – together

We deliver under a highly collaborative approach, working hand in hand with our clients, our supply chain, and the community, establishing a shared vision, culture, and unified performance targets to ensure we build trust, establish strong relationships, and drive high levels of engagement from all parties. This ensures that together we can identify risks and develop mitigations early to deliver on time, on budget to high levels of satisfaction for all involved.

Engineering: Pragmatic, constructability-focussed design, leveraging our expertise as a builder.

Procurement: Unrivalled performance for UK major onshore pipeline delivery ensuring cost efficiency and resilience.

Construction: Extensive experience in complex pipeline projects, with a focus on safety, community satisfaction and sustainability using a UK workforce and supply chain.

Pre-commissioning and commissioning: Streamlined processes to ensure operationally ready handover.

Our partnership with LBCCS

CO2 transportation and storage in the UK

In April 2025, we were selected by Liverpool Bay CCS Limited (LBCCS), a member of the global energy-tech company, Eni, as one of the primary contractors to deliver CO2 Transportation and Storage (T&S) infrastructure. The ULIS project is worth approximately £250 million over a three-year period.

This facility will be instrumental in enabling the landmark HyNet CO₂ pipeline, which aims to unlock a low carbon economy for the north west of England and north Wales. The pipeline will be the first step in unlocking the benefits and ambitions of the wider HyNet North West project and achieving the UK’s net zero target by 2050.

The HyNet CO₂ pipeline will take CO₂ captured by industrial emitters across the region and transport it through new and repurposed infrastructure to permanent storage in depleted natural gas reservoirs under the seabed in Liverpool Bay.

ULIS has been chosen by LBCCS to work on the pipeline as part of an engineering, procurement, installation, and commissioning (EPIC) project. The pipeline will start in Ince, Cheshire, and ULIS will cover over 34 km of new pipeline, in conjunction with 24 km of existing pipeline, which will finish in Point of Ayr, North Wales.
