London Stansted Airport

We have been providing operation and maintenance support for the electrical distribution system at Stansted Airport since 1993.


London Stansted Airport is an international airport located in Essex. It serves 200 destinations across Europe, Middle East and Africa and serves as a base for a number of major European low-cost carriers.



Stansted Airport serves over 28 million passengers each year. The airport is supported by an electrical distribution system that comprises 56 high voltage (HV) substations and 104 transformers as well as the associated high voltage and low voltage (LV) cables connecting from the main 33kV intakes down to street lighting supplies. It has different categories of supply importance from critical (affecting aerodrome licensing requirements) to non-essential. Supporting these different supply categories requires varying equipment and system design with a variety of switchgear types from different manufacturers.


Approach and innovation

It is critical to Stansted Airport that their operations remain safe, resilient and efficient, our role is vital to ensuring this is achieved through our operation and maintenance support.

The scope of work we are delivering includes:

  • Scheduled asset replacement including cable, transformers, LV and HV switchgear, batteries and chargers
  • HV and LV cable installation and jointing
  • Electrical infrastructure design, project management and project delivery
  • Supply and connection of emergency generation including ongoing monitoring of assets



Our work with Stansted Airport helps keep London’s third busiest airport operational. The operation and maintenance work we deliver has also resulted in quantifiable cost savings, productivity gains, increased compliance, improved environmental outcomes and enhanced customer satisfaction among airport partners and users.
