About Us - National Gas Services

Leaders in pipeline maintenance

Who we are

National Gas Services, previously known as “PMC” was established in 1975 as the emergency response unit, servicing the national and local network of gas pipelines.

Today, our technicians and engineers continue to work across the pipeline network from strategically positioned depots in England, Scotland and Wales. We have developed such a large portfolio of specialist skills and experience that we are considered the leading authority on emergency and planned solutions in the field of pipeline repair, replacement, maintenance and intervention.

Our expertise spans a wide range of materials and pressures used in both Gas Transmission and Distribution. We undertake works as Principal Contractor, contractor and sub-contractor.

Our focus on safety and commitment to protecting the environment is our top priority. 

We have established key relationships with customers and stakeholders and work with each customer to understand their issues and needs and develop bespoke solutions. 

Leaders in innovation

We are constantly innovating and creating solutions that benefit our clients. We regularly create bespoke solutions for specific pipeline issues and work in conjunction with design contractors to undertake design approvals.

Some examples of recent innovations include the following:

  • Vent and sealant line epoxy repair technique. An in-house innovation that allows repair to the valve while the gas stays live, resulting in significant savings.
  • Sealant point epoxy support, a process that installs an epoxy support base around a below ground sealant point adaption to provide support during reinstatement.
  • Lapping tool. This is a repair method that avoids the need to replace a valve. This has been used multiple times to repair and recover valves, resulting in significant savings.
