The NHS’s commitment to achieving Net Zero emissions by 2040 is entering a pivotal stage. Back in July, NHS England required all Trusts and Integrated Care Boards (ICBs) to submit their updated green plans, and now the emphasis is squarely on delivery. Strategy must translate into real, measurable action across estates and facilities.
This next phase of climate action coincides with a unique opportunity. Targeted funding via the Public Sector Decarbonisation Scheme (PSDS) is enabling NHS bodies to invest in energy-efficient infrastructure, from smart metering and insulation, to low-carbon heating systems and intelligent energy platforms. For those receiving support, now is the time to embed the digital foundations that will underpin long-term carbon reduction, operational resilience, and clinical benefit.
Yet many Trusts still face significant barriers: fragmented data, inconsistent reporting, manual processes, and limited visibility into how, when, and where energy is being consumed. This is where energy management technology plays a critical role.
Data is the missing link in decarbonisation
For NHS estates teams, decarbonisation isn’t just about boilers, lighting, or electric vehicle (EV) fleets. It’s about data. Without a clear understanding of energy use at both macro and micro levels, it’s almost impossible to identify waste, prioritise upgrades, or track progress.
This information gap remains one of the biggest blockers to sustainable healthcare. Without the ability to effectively pinpoint energy usage inefficiencies, and benchmark performance across different sites, teams will struggle to identify the investments likely to build the biggest impact, and stay on track to meet Green Plan targets and 2040 Net Zero goals.
Hospitals and healthcare facilities are among the most energy-intensive buildings in the public sector. Yet many Trusts still lack the granular data needed to identify inefficiencies and target improvements effectively. With a smart energy monitoring system, powered by IoT sensors and analytics, NHS organisations can gain real-time visibility into energy usage down to the level of individual rooms and devices.
A real-world example: turning data challenges into actionable insights
One NHS organisation recently partnered with MRI Software to transform how they manage energy across a complex network of hospitals, clinics, and healthcare facilities. Like many Trusts, they faced the mounting challenge of delivering on ambitious carbon reduction goals while also improving operational efficiency. The pressure to demonstrate measurable progress against emissions targets had intensified, particularly with mandatory Net Zero deadlines on the horizon and heightened board-level scrutiny of sustainability performance.
However, the path to transformation was not straightforward. One of the first barriers the Trust encountered was around monitoring and compliance. Monthly energy reporting was time-consuming and often incomplete, with limited visibility into usage trends, performance anomalies, or site-level variances. This made it difficult to generate accurate reports for the board — or assess the effectiveness of previous interventions. Strategic planning was also hindered by a lack of forward-looking insight. The Trust needed to forecast future carbon reductions aligned to NHS Net Zero milestones for 2025, 2030, 2035, and 2040, yet had no robust mechanism for modelling emissions projections against evolving carbon factors or capital plans.
Data quality and fragmentation
A further challenge stemmed from data quality and system fragmentation. Much of the Trust’s energy information was reliant on manual input, legacy spreadsheets, or siloed platforms. This made the process prone to billing errors, data duplication, and significant gaps in historical reporting. Incomplete or inaccurate records weakened the credibility of internal reporting and undermined the Trust’s ability to secure investment for sustainability projects.
Perhaps most critically, the energy team faced a cultural and communications challenge. While the facilities team understood the scale and importance of the Net Zero agenda, they struggled to secure sustained engagement from clinical departments, operational managers, and senior leadership. There was a need to raise awareness, increase accountability, and build a more collaborative approach to energy management.
To address these intersecting issues, the Trust deployed MRI Energy as a centralised platform to digitise reporting, consolidate disparate data sources, and provide a unified view of energy performance across their estate. The solution allowed the organisation to ingest and validate a wide range of data sets, including utility billing records, half-hourly Automated Meter Reading (AMR) data, historic consumption figures, and carbon emissions factors. The system also integrated Degree Day weather variables to contextualise consumption patterns and support accurate forecasting. By automating data collection and validation, the Trust could ensure greater accuracy, reduce the administrative burden, and unlock strategic insight that was previously out of reach.
Creating a sustainable and compliant energy future
This transition not only improved internal reporting and regulatory compliance, but also empowered the Trust to proactively identify opportunities for savings, support board-level decision-making, and build the case for continued investment in energy efficiency and sustainability.
The introduction of MRI Energy provided the Trust with a digital foundation for transforming how energy data is used across its operations. One of the most immediate benefits was the automation of reporting processes. Previously, staff were spending significant time gathering, cleaning, and compiling data from multiple sources. With the new platform in place, routine reports were generated automatically, reducing the risk of human error and freeing up internal resources to focus on strategic initiatives rather than administrative tasks.
Another critical improvement was the early detection of anomalies in energy usage. By integrating real-time metering data with automated alert systems, the platform allowed the energy team to quickly identify unusual patterns or unexpected consumption spikes. Whether caused by faulty equipment, system inefficiencies, or behavioural changes, these anomalies could now be investigated and resolved before escalating into larger cost or compliance issues.
Tracking performance
The Trust also benefited from improved tracking of key performance indicators (KPIs). This visibility made it easier to measure progress against emissions benchmarks, operational efficiency targets, and cost-reduction goals. With clearly defined metrics, the Trust could assess the effectiveness of its energy interventions and adjust its strategy in real time.
Scenario modelling further enhanced the Trust’s strategic capabilities. With the ability to forecast performance against future emissions factors and regulatory milestones, the energy team could visualise the likely impact of different interventions over time. This forward-looking capability proved essential for long-term planning and informed the development of phased investment programmes to meet 2025, 2030, and 2040 sustainability milestones.
Improved communication with senior stakeholders was another key benefit. Using tailored dashboards and visual reporting tools, the team could present complex energy data in a clear, accessible format. This helped strengthen engagement at board level and across departments by turning data into actionable insight. Decision-makers were better equipped to understand progress, support investment, and champion sustainability across the wider organisation.
One year into the implementation, the Trust is already seeing tangible results. Energy-saving opportunities are being identified and actioned more quickly, the accuracy and reliability of internal reporting have improved, and there is a growing sense of ownership and accountability around sustainability performance.
The clinical case for energy insight
While the environmental and financial benefits of smart energy management are well documented, its critical role in supporting clinical environments is often overlooked. In hospitals and healthcare settings, maintaining optimal environmental conditions, such as temperature, air quality, and lighting, is not just a matter of efficiency, but of patient safety and recovery. This is especially true in high-dependency areas like operating theatres, intensive care units, and medication storage facilities, where even minor deviations can have serious consequences.
With MRI Energy integrated alongside IoT sensors and smart building management systems, estates teams are gaining the ability to monitor and manage these conditions in real time. For example, the platform enables facilities teams to maintain consistent ward temperatures, which not only enhances patient comfort but also supports infection control protocols by reducing temperature-related risks.
The system can also be configured to continuously monitor cold storage units such as fridges used for medications or vaccines, ensuring they remain within specified temperature ranges. Any deviation from acceptable thresholds triggers an alert, allowing for swift intervention before spoilage or loss occurs, which helps maintain compliance and avoids unnecessary waste.
Perhaps most importantly, the integration of MRI Energy with IoT technology supports automated fault detection. When performance thresholds are breached, whether due to equipment malfunction, external temperature changes, or other factors, the system can immediately generate maintenance alerts. This approach reduces unplanned downtime, enhances operational resilience, and helps align estate management with the Care Quality Commission’s (CQC) expectations for safe, effective clinical environments.
Investing in infrastructure
Implemented well, smart energy management has the potential to act as a catalyst for broader transformation across the NHS estate. As Trusts invest in capital upgrades, energy platforms support a parallel shift towards intelligent infrastructure. In this context, buildings are no longer static assets; they become responsive environments where performance is continuously monitored, maintenance is predictive, and systems operate only when needed.
The scale and diversity of the NHS estate makes this shift both necessary and powerful. With many facilities ageing and under pressure to decarbonise, the ability to capture and act on real-time data has never been more valuable.
MRI Energy enables healthcare providers to integrate energy data directly with CAFM systems, establishing a clear link between asset condition and operational performance. This connection supports more informed maintenance strategies and ensures investment is targeted where it will have the greatest impact.
IoT sensors extend visibility even further, capturing granular data on air flow, lighting levels, humidity, and occupancy in high-priority zones. Combined with an analytics engine, this insight allows for automated building controls, adjusting HVAC settings, reducing lighting, or shutting down idle equipment based on environmental triggers. These dynamic adjustments help optimise both comfort and efficiency without relying solely on manual intervention.
In addition, MRI Energy supports forward-looking planning. The platform’s forecasting capabilities allow organisations to estimate the carbon impact and financial return of planned decarbonisation projects, providing an evidence base for prioritising investment.
This isn’t a vision of the future — it’s already being done. NHS Trusts are increasingly adopting these connected, data-led approaches as they work toward Net Zero and build more resilient, intelligent infrastructure from the ground up.
Elevating estates with a system-wide view
As Integrated Care Systems (ICSs) mature, the need for joined-up visibility across estates is becoming more urgent. NHS leaders want to move beyond siloed facility management and toward a system-wide perspective, where data can be analysed across multiple organisations, geographies, and property types.
MRI Energy makes this possible with flexible reporting structures and hierarchical site architecture. Estates and sustainability teams can drill down into the energy performance of individual buildings or zoom out to evaluate an entire Trust or ICS. This adaptability provides a strategic advantage in an environment where regulators, boards, and the public increasingly demand transparency and accountability.
Beyond compliance, this broader view unlocks opportunities for cross-system collaboration. For example, procurement teams can use shared energy profiles to negotiate collective contracts or prioritise sustainability-aligned vendors. Multiple sites can collaborate on capital funding bids, improving their chances of securing decarbonisation grants by presenting unified plans. By benchmarking performance across regions, Trusts can share lessons, highlight innovation, and accelerate progress through peer learning.
MRI Energy acts as a common platform that connects these efforts, helping NHS organisations move from local improvements to coordinated, regional-scale impact.
A call to action
With less than a year remaining before the Green Plan deadline, NHS Trusts and Integrated Care Boards (ICBs) must act decisively. For those receiving support through the Public Sector Decarbonisation Scheme (PSDS), this is a pivotal opportunity to demonstrate leadership and measurable progress. For others, it’s a chance to build a stronger business case for future funding by laying the groundwork now.
In either case, success will depend on the quality and accessibility of data. Without clear, reliable insight into current energy performance and the impact of interventions, it will be difficult to track progress or justify investment.
