Chesterfield Royal Hospital

C3 Group supported Chesterfield Royal Hospital, one of Derbyshire’s largest healthcare providers, with a comprehensive Heat Decarbonisation Plan designed to modernise infrastructure, reduce emissions, and support the NHS’s Net Zero Carbon goals. This project addresses one of the UK’s most energy-intensive public buildings, without disrupting patient care.

Project Overview

Designing a Low-Carbon Future for a 24/7 Facility

Built in 1984, Chesterfield Royal Hospital relied on an ageing gas-fired heating system producing 5,740 tonnes of CO₂ annually. C3 Group was appointed to develop a low-disruption, phased strategy to electrify the site’s heat systems – reducing emissions while improving long-term energy security and resilience.

What We Did

Feasibility-Driven Planning, Designed Around Patient Care

Our team delivered a detailed review of existing infrastructure and mapped out low-carbon alternatives that could be implemented without interfering with essential hospital operations.

Scope of Work:

Full site survey and heat demand modelling
Feasibility assessment for ground, air and water-source heat pumps
Building fabric analysis to reduce heat loss and improve efficiency
Electrical infrastructure assessment to support electrified systems
Engineering design for new heat generation and distribution systems
Alignment with NHS energy standards and PSDS funding eligibility

The result was a phased transition plan designed for reliability, compliance, and minimal disruption.

The Results

Cutting Carbon While Enhancing Care Environments

Chesterfield Royal Hospital is now on track to replace its legacy system with a fully electrified, low-carbon solution.

Key Outcomes:

Significantly reduced emissions in line with NHS net zero targets
Improved building efficiency and thermal comfort
Reduced reliance on volatile gas markets
A resilient energy system aligned with long-term operational needs
