Supporting Mount St. Mary’s College with 100% Funded LED Lighting and Boiler Replacement Projects

About the School

Mount St. Mary’s College, established in 1842, is one of the oldest independent schools in the UK. Situated across two campuses – the Senior School (Mount St. Mary’s College) with 360 students and the Junior School (Barlborough Hall Prep School) with 190 students – the institution provides education for over 550 pupils in total.


The school’s historic buildings, while full of character, present ongoing challenges in terms of energy efficiency. Aged lighting systems and heating infrastructure have long driven up energy consumption and maintenance costs.

The Challenge

Mount St. Mary’s faced two significant infrastructure challenges:

1. Outdated Lighting

The school’s classrooms, corridors, and sports facilities were fitted with legacy lighting systems, resulting in high electricity consumption and poor-quality lighting environments. Upgrading to energy-efficient LED lighting would not only improve the learning and teaching experience but also deliver long-term savings.

  • Annual savings: Substantial reduction in energy costs
  • Payback period: Estimated at 4 years
  • Additional benefits: Better lighting quality, lower maintenance

2. Aged Boiler Systems

The school operates two central plant rooms with a total of six floor-mounted boilers, all over 25 years old. Reliability had become a concern, and the high maintenance costs were impacting the annual budget.

  • Annual gas spend: ~£400,000
  • Projected efficiency gain: 25%
  • Estimated annual savings: ~£100,000
  • Improved reliability: Stable heating supply across all school buildings

Despite these challenges, like many independent schools, Mount St. Mary’s faced constraints in allocating capital for such significant upgrades.

A Word from the School

“Working with Sustainable Energy Finance was a very positive experience. The projects were complex, particularly due to the age of our buildings and the nature of the funding requirements, but their team took the time to understand our operations and delivered tailored funding solutions that worked for us. Their guidance and expertise helped us move forward on essential infrastructure upgrades that would otherwise have been delayed. We wouldn’t hesitate to work with them again.”
