Civil engineering, mechanical and design, fully coordinated. Your project deserves a contractor who understands the full picture, with joined-up thinking, simplified procurement and infrastructure that performs as it should.
Enex Civils combines civil engineering, heat networks and design capabilities so you get joined-up thinking, simplified procurement and infrastructure that works exactly as it should. Switch between the seven service lines below.
We deliver the essential groundwork that forms the foundation of all infrastructure projects. From trenching and excavations to site preparation, drainage installation, ducting, chamber construction, RC works, paving works, and full surface reinstatement, our civil engineering teams operate across a wide range of environments. Whether working on greenfield developments or complex urban sites with existing utilities, we install infrastructure safely, efficiently, and to adoptable standards.
Every project starts in the ground. Our teams carry out critical earthworks that support drainage systems, heat networks, highways, and multi-utility installations. We manage trenching and excavation, pipe bedding and backfill, manhole and chamber construction, ducting, paving, and full reinstatement. Quality at this stage is essential, what goes in the ground today must perform reliably for decades, and we ensure it is delivered right first time.
Reliable and efficient groundworks services forming strong foundations for successful project delivery. We offer a comprehensive range of works, starting with site investigations and surveys to inform safe and effective delivery. Our works include site clearance, bulk and detailed excavation, utility trenching, and drainage installation, ensuring all underground infrastructure is installed accurately and in line with project requirements.
We also undertake in-situ concrete works, foundations, and substructures, alongside external works packages including road construction, paving, and both carriageway and footpath reinstatement. Our experienced teams work with precision and efficiency, delivering safely, to programme, and to the highest standards of quality.
We provide fully integrated heat network delivery, combining civil engineering expertise with coordinated mechanical installation to deliver a complete, end-to-end solution. Our civil works include trenching, excavation, ducting, chamber construction, and reinstatement, ensuring the network is installed safely, efficiently, and to adoptable standards.
Alongside this, we deliver mechanical installation through experienced specialist partners to install the pre-insulated steel pipework. With coded welding, rigorous pressure testing, and full material traceability, every system is installed to perform reliably long term. By coordinating both civil and mechanical elements under a single delivery approach, we streamline programmes, maintain quality, and provide clients with a dependable, fully managed heat network solution.
Proven drainage and water solutions installed to the highest standards, ensuring compliance and long-term performance. We specialise in the installation of foul and surface water drainage systems, including deep drainage and manhole chambers. Our experienced teams work to current regulations and best practices, delivering systems that are robust, compliant, and built for long-term reliability.
In addition, we provide excavation, backfilling, and reinstatement services in support of water main installations, working alongside utility providers and principal contractors to ensure safe, efficient, and compliant delivery. Our team understands the importance of maintaining programme, protecting existing services, and delivering high-quality reinstatement to required specifications.
We provide reliable civil engineering support for electric and gas utility installations, working in collaboration with utility providers, private clients, and developers. Our services include excavation for service routes, installation of ducting for electrical infrastructure, and careful backfilling and reinstatement in line with required specifications.
Our experienced teams understand the importance of protecting existing services, maintaining site safety, and minimising disruption to surrounding areas. We deliver all works efficiently and in compliance with current regulations, ensuring reinstatement is completed to a high standard across carriageways, footpaths, and public spaces.
We provide comprehensive design capability through our trusted design partners, supporting projects from initial survey through to construction-ready solutions. This includes early-stage investigations such as GPR surveys and utility mapping, enabling accurate understanding of existing ground conditions and constraints.
Building on this, we coordinate detailed design development, ensuring all civil engineering, drainage, heat network, and utility requirements are fully considered and aligned with project objectives. By integrating design with our delivery expertise, we help identify risks early, improve buildability, and ensure designs are practical, compliant, and ready for construction. This joined-up approach provides clients with confidence that projects are well planned, efficiently delivered, and set up for long-term performance.
Well-managed, efficient delivery of construction works, ensuring projects are completed safely, on time, and within budget. We take a proactive approach to project delivery, working closely with clients, consultants, and stakeholders to ensure smooth coordination on site.
From mobilisation through to completion, we manage resources, programme and quality to maintain progress and minimise risk. Our structured approach ensures consistent, reliable delivery across all projects, with safe, efficient site operations and clear reporting at every stage.
Every service line is backed by the full breadth of our specialist trades. Below, a closer look at the deliverables that sit inside each scope.
From enabling works and earthworks to drainage, utilities, structures and reinstatement, we deliver safe, high-quality civil engineering solutions to support projects from start to finish.
Civil engineering →Enabling works, excavation, earthworks, drainage, services, foundations and concrete works, delivered safely, efficiently and to specification.
Groundworks →Specialist civil engineering for heat networks including trenching, backfilling and reinstatement, delivered safely, efficiently and to the highest standards.
Heat networks →Manhole chambers, water main support, careful excavation and reinstatement working alongside utility providers.
Drainage & water →Safe and efficient excavation, installation support, backfilling and reinstatement for electric, gas, water and telecoms utilities, delivered to specification with minimal disruption to communities and networks.
Electric & gas →Route planning, clash detection, GPR surveys, construction drawings and O&M manuals, delivered in collaboration with our trusted design partners.
Design & consultancy →A clear, repeatable process. Five phases that keep programme, quality and safety on track from day one.
Early engagement with clients to shape better schemes, optimise route, and avoid problems downstream.
Material specification, supply chain coordination, programme development and method statements.
Site set-up, traffic management, GPR utility detection, welfare provision, ready to break ground safely.
Coordinated civil and mechanical works, integrated programme, daily supervision and quality control.
Pressure testing, commissioning support, reinstatement to adoptable standards, full as-built documentation.
Every project is different, but our approach remains consistent. We focus on collaboration, clear communication, and delivering high-quality infrastructure safely, efficiently, and to programme.
The best outcomes come from early involvement. We work with clients from feasibility and design stages, providing practical input that improves buildability, manages risk, and helps avoid issues later in delivery.
By managing civil engineering works and coordinating design and mechanical installation, we provide a joined-up delivery model. This reduces interface risks, improves efficiency, and ensures clear accountability throughout the project.
We maintain high standards across every stage of delivery. Through inspection, testing, and detailed documentation, we ensure all works meet required specifications, regulatory standards, and long-term performance expectations.
We deliver civil engineering and utility infrastructure across a wide range of sectors. Our experience working in varied environments gives us a clear understanding of the technical, operational, and programme requirements unique to each project.
