About us

Welcome to Ergéa. We enable the potential of healthcare.

Ergéa is the leading service provider of Managed Equipment Services (MES) for the NHS and the private health sector in the UK. With more than 20 years of operational experience, we bring a wealth of expertise and a deep understanding of the challenges facing our clients in the UK and Ireland.

Ergéa UK was formed in 2022 following the acquisition of two market-leading medical service companies – Althea UK and Medipass Healthcare – by Ergéa Group, a pan-European cancer care and diagnostic imaging services platform.

Ergéa UK by numbers

Our story

The Ergéa Group has been formed through acquisitions in the healthcare sector, bringing together companies with distinct business models and company cultures. We chose the name Ergéa to symbolise our new, unified identity and the patient-centric mindset we share across the group.

Like Western medicine itself, the name Ergéa has Greek roots. In Greek, érgo means ‘work’, and ygeía means ‘health’. The blending of these two words as Ergéa can be roughly translated to “working for health”.

The translation ‘working for health’ captures our ambition to bring better healthcare to the place where it has the most significant impact – at the patient interface. This is where the healthcare system meets the patient to make a difference in each individual’s life.


Our journey

We have a storied history dating back to 2002 when we were the pioneers in vendor-independent managed equipment services (MES) in the UK. Since then, we’ve become the leading MES player in the UK market – driven by our excellent service record and commitment to supporting NHS and private hospitals.

Over the years, our service offering has expanded to include maintenance services and specialist MES services across a broad range of service modalities, including radiology, radiotherapy, endoscopy, cardiology and surgical theatres. As we’ve grown the breadth of our service offering, we’ve consistently helped our customers implement the latest medical technologies and optimise their processes, enabling better medical outcomes and improved patient experiences.

As we move forward, we remain committed to serving our customers in the same spirit of partnership, diligence and integrity that have helped us gain their trust and secure our market-leading position in the UK.

Here are some key milestones on our journey.
