TNS Contractors was appointed  to deliver a comprehensive mechanical and electrical upgrade to the station’s heating and cooling infrastructure as part of the operator’s wider Net Zero strategy to eliminate fossil fuel heating systems across its estate by 2030.

The project involved the complete removal of the existing oil-fired heating installation, including the decommissioning and removal of the oil storage tank, boiler plant, associated heating pipework, pumps, valves and ancillary equipment. Environmental ground testing was undertaken following the tank removal to verify the area was free from contamination prior to reinstatement, ensuring the works were completed safely and in accordance with environmental best practice.

To replace the legacy system, TNS Contractors installed a new energy-efficient Variable Refrigerant Flow (VRF) heating and cooling system, supplemented by electric panel heaters where required to provide complete climate control throughout the station. A new mechanical distribution board was installed, together with a new sub-main supply, ladder rack containment system and all associated power and control infrastructure.

The installation also incorporated a new Building Management System (BMS) with Learnd remote monitoring, enabling intelligent control, energy monitoring and remote fault diagnostics. System operating schedules, temperature set points and user permissions were configured in accordance with Greater Anglia’s heating, cooling and environmental policies to maximise efficiency while maintaining passenger and staff comfort.

Our works included all associated mechanical and electrical installations, containment, cabling, commissioning and testing. Delivered within a live operational railway station, the project required detailed planning and phased delivery across both normal operating hours and out-of-hours possessions to minimise disruption to passengers and station operations whilst maintaining the highest standards of safety and workmanship.

The completed scheme has modernised the station’s mechanical and electrical infrastructure, replacing an ageing fossil fuel heating system with a low-carbon, intelligent solution that improves reliability, reduces maintenance requirements and significantly lowers operational energy consumption. The project represents a key step in Greater Anglia’s ongoing investment in sustainable infrastructure and an enhanced environment for both passengers and staff.
