Market leaders in engineering design for high pressure pipelines and associated infrastructure – keeping energy moving efficiently and reliably throughout the UK and Ireland.
Visit the Premtech websitePremtech is a company within National Gas. We are the UK's foremost engineering design consultancy specialising in high-pressure onshore pipelines and associated infrastructure for the energy sector. We have more than 15 years’ experience in designing complex pipelines and installations for gas transmission and distribution networks across the country – encompassing both new pipelines and installations, and existing asset upgrades.
Innovation in pipeline design
We adapt and tailor our extensive range of services to the specific requirements of each client or project. We can provide everything from engineering consultancy or design management, through to fully integrated design and engineering services. We have vast experience of working on innovative, nationally significant projects in highly regulated environments.

Pioneering pipelines for net zero gases
As the energy industry transitions to net zero, Premtech is at the forefront, applying advanced technologies, innovation and engineering expertise to support the future of energy.
Our dedicated team, Premzero, focuses on designing pipelines and installations, including repurposing existing natural gas infrastructure, to transport hydrogen, carbon dioxide and biomethane.
Our areas of expertise include:
Pipeline and installation design
For high-pressure natural gas, hydrogen, carbon dioxide, liquid fuel and multi-product pipelines.
3D modelling
Including Building Information Modelling (BIM) and Digital Twin for gas installations, including pipework, ancillaries and civil infrastructure.
Hazardous area classification
To identify, assess and classify areas where there is a potential for a hazardous atmosphere, using recognised industry standards.
Site surveys
Drone-based scanning, laser scanning, cathodic protection (CP) surveys and visual asset health surveys.
Design assurance
Including design reviews, approvals and appraisals (GL/5, G/35, G/17, PS/5) in various disciplines for both natural gas and hydrogen.
Digital and virtual reality (VR) visualisations
For operation and maintenance training, digital construction, stakeholder and public engagement, and safety studies.
Design project management
Comprehensive oversight and management of pipeline and installation design projects.
Partnerships
We have a supply chain with the breadth and depth of expertise to support our projects, offering services such as stress analysis, including finite element analysis (FEA) through to planning and environmental consultancy.

Multi-disciplinary engineering expertise
Premtech has a highly experienced team of multi-disciplinary engineers, with expertise spanning mechanical, process, civil, cathodic-protection, electrical and instrumentation engineering. Our engineers are supported by dedicated Computer-Aided Design (CAD) specialists, a digital team and skilled 3D-modelling and virtual reality (VR) technicians.

Advanced visualisation technologies
We use virtual reality (VR) and mixed reality (MR) to enhance pipeline design visualisations. Our capabilities include 3D visual renders, animations and desktop VR representations of pipeline-related sites, operations and construction activities. This technology can transform the way projects and assets are managed, enhance public and stakeholder engagement on critical pipeline developments, and support training and safety management.

Mentoring and recruitment
We recognise the need to attract and develop new talent for the industry – and with the challenge of net zero, this has never been more important. Our senior staff have considerable experience in the industry, which we use to mentor and coach our junior staff to become tomorrow’s engineers and managers – and continue our legacy.
