Essentia helps Whipps Cross Hospital to save £600k per annum with Energy Performance Contract


Essentia’s award-winning sustainability team supported Barts Health NHS Trust to procure an operations and maintenance Energy Performance Contract (EPC) which delivers 20% carbon savings and a fully managed energy service with a 1.45-year payback.

The requirement

The client wished to establish a managed service contract for the operation and maintenance of its central boiler house and associated plant, including a water bore hole.  The Trust sought to connect the installed, but unused, combined heat and power engine to a newly upgraded high voltage system.

The Trust intended to deliver financial and carbon savings, outsource servicing and billing, maximise existing assets, improve business continuity and reduce the cost of ongoing backlog maintenance.

Essentia’s approach

Essentia’s flexible energy performance contract (EPC) framework and contract documentation provided Whipps Cross with a clear, simple and streamlined process to establish an operations and maintenance contract for its energy infrastructure, which also delivered guaranteed savings.

The Essentia team understood the key drivers and ensured the supply chain was fully briefed to deliver the highest quality submissions for evaluation.  Essentia provided fit for purpose contract documentation and partnered with the client and supply chain to ensure smooth and efficient delivery of the project.


Whipps Cross appointed Engie to deliver the project, which delivers a 20% carbon saving and pays back in 1.45 years.  The Trust also achieves guaranteed energy and maintenance cost savings of over £600k per annum.

Essentia’s strategic partnership with Tees, Esk and Wear Valleys NHS Foundation Trust has been instrumental in developing a long-term sustainability plan which embeds sustainability into the everyday business of the Trust, and has set them on course to deliver a £1.5 million energy saving project.

The client

Tees, Esk and Wear Valleys NHS Foundation Trust provides a range services for people living in County Durham and Darlington, the Tees Valley and most of North Yorkshire.

With over 6,500 staff and an annual operating income of over £300 million, it delivers services by working in partnership with local authorities, clinical commissioning groups and a range of other providers.

The issue

The Trust is keen to demonstrate that it has a sound environmental management plan and has sustainability at the heart of its operations as well as cut emissions in-line with Government targets.

After a competitive tender process, the Trust chose to work with Essentia, having been impressed by its award-winning sustainability team.

Our approach

Essentia has now acted as a strategic partner to the Trust for four years, helping them to establish its SDMP and working with the Trust to drive continuous improvement.

The project included its three main sites – Roseberry Park, West Park Hospital and Lanchester Road Hospital – all of which have significant energy demands.

The planned works include the installation of combined heat and power (CHP) and, unusually, significant solar energy generation.

Using Essentia’s industry-leading energy performance contracting (EPC) framework to procure a preferred supplier from its highly skilled supply chain.

Throughout all its work with the Trust, Essentia worked closely with the estates and facilities management team to advise them on areas of efficiency and cost savings and supported the wider Trust to embed sustainability in its daily activities.


Essentia and the Trust have been able to identify opportunities for energy efficiencies and the use of renewables as well as begin to embed a culture of sustainability into the business operations of the Trust.  The programme is set in the context of the wider-Trust objectives, and benefits patients and staff alike.
