Decarbonisation (EPC)

We support businesses to plan and deliver practical decarbonisation works that improve building efficiency, while protecting day-to-day operations. From targeted upgrades to heat decarbonisation, we combine our engineering expertise with our maintenance support to help your business reach its energy and carbon goals. Our Commercial EPC Compliance strategy focuses on the elements of your building that make the biggest difference to your Energy Performance Certificate (EPC) rating and the operational costs.

Commercial EPC Assessments & Improvement Strategies

Improving an Energy Performance Certificate (EPC) rating starts with understanding how your building performs today. Our engineers carry out comprehensive site surveys to assess existing building services, identify opportunities to improve energy efficiency and develop practical recommendations that align with your operational and budgetary requirements.

Whether you’re targeting minimum EPC compliance, reducing operational costs or planning a phased decarbonisation programme, we provide clear, prioritised upgrade strategies supported by indicative cost plans. From quick-win improvements to longer-term capital investment, we’ll help you build a realistic roadmap towards improved building performance and lower carbon emissions.

Heat Recovery Systems

Heat recovery is typically one of the most cost-effective starting points when it comes to building decarbonisation, by capturing the energy that is being wasted. Our engineers are experts at assessing how your existing systems operate and identifying where upgrades are needed or where heat recovery systems can be implemented. They will consider things such as:

Retrofitting heat recovery to existing air handling units (AHUs)
Replacing outdated heat exchangers with higher-efficiency options
Optimising control strategies to deliver recovered heat
Updating ventilation systems

Our suggestions will support your wider heat decarbonisation strategies to cut carbon emissions by reducing the amount of new heat that needs to be generated.

Heat Pumps (Air & Ground Source)

Our engineers will provide a full lifecycle service for your building’s heat pump. This includes both air source and ground source heat pumps. They will consider each business individually, looking at the specific needs of each building, such as the existing heating and cooling systems, noise constraints and planning considerations, integration with existing systems, and any opportunities to provide both heating and cooling from the same plant.

We will design control strategies that ensure a low-carbon heat source is used as the primary generator when we have introduced heat pumps alongside the existing plant. With this, the aim is that conventional boilers will provide top-up or backup only when required.

Condensing Boilers

If your building is on a journey towards full heat decarbonisation, high-efficiency condensing boilers are vital. By upgrading your old, non-condensing boiler to a modern condensing unit, you can see immediate reductions in your carbon emissions and fuel costs. Our expert team will evaluate your current boiler plant to find the most efficient and suitable upgrade options. This may include:

Replacing legacy boilers with newer, condensing models
Reconfiguration of circuits to maximise condensing operations
Integrating with new or existing BMS for closer control and monitoring

We will also look out for opportunities to reduce system temperatures so that boilers and future heat pumps can operate at their maximum efficiency.

Looking for a Complete EPC Strategy?

Decarbonisation isn’t about installing a single technology – it’s about understanding which improvements will deliver the greatest impact for your building. Our Commercial EPC Compliance Hub brings together guidance on EPC regulations, compliance requirements and practical upgrade strategies to help you plan with confidence.

Whether you’re looking to improve your EPC rating ahead of a lease renewal, understand your compliance obligations or develop a phased investment plan, you’ll find expert advice and resources to help you get started.
