⚡ Major electrical upgrades are progressing at Pilgrim Hospital, Boston
Pilgrim Hospital is moving forward with a significant programme of high-voltage (HV) and low-voltage (LV) electrical infrastructure upgrades designed to strengthen the site’s power network, improve resilience and support future clinical services.
A key part of the programme is Substation 3, where a contract worth almost £992,000 was awarded to Sudlows Limited in February 2026. The works include upgrades to the main electrical switchboards and generator infrastructure.
This sits alongside a wider programme of investment across the hospital site, including new substations, underground cabling and upgraded power distribution.
The improvements are intended to support major developments at Pilgrim Hospital, including the new Emergency Department, modern clinical facilities and the continued rollout of digital systems such as electronic patient records (EPR).
🏥 Why does this matter?
Reliable electrical infrastructure is essential for a modern hospital. It helps power operating theatres, diagnostic equipment, IT systems, emergency services, medical technology and backup systems around the clock.
The work is being delivered in phases, with different substations and infrastructure elements progressing alongside wider developments across the hospital estate.
A further planning application has now been submitted for the construction of a new HV substation at the Pilgrim Hospital site:

⚡ What is an HV substation?
A high-voltage substation receives, transforms and distributes electricity around a site. At a hospital, this type of infrastructure can help increase electrical capacity, improve reliability and strengthen resilience as services, buildings and technology expand.
Together, these projects point to continued investment in the infrastructure behind patient care at Pilgrim Hospital.
A stronger power network means a more resilient hospital — helping support healthcare in Boston for years to come.
