It is the first time that the Trusts have joined together to manage facilities and estates services across all local NHS services, including health centres, hospitals and community services.

The seven-year deal is with Leicestershire Partnership NHS Trust, University Hospitals of Leicester NHS Trust and the Leicester City, Leicestershire County and Rutland Primary Care Trust Cluster.

Under the £300m FM part of the contract, Interserve will provide investment to improve the buildings and facilities.

The deal includes delivery of catering, cleaning, maintenance and security across more than 550 NHS buildings and properties, totaling 490,000m2 and nearly 3,100 beds.

The second part of the contract also includes a new partnership to make the best use of the NHS buildings and estate and, using Interserve’s supply-chain provider Capita Symonds, will support the NHS in delivering major modernisation projects.

This is expected to take the final value of the deal up to £700m over the term.

The signing of this contract follows a two-year procurement process which has seen the NHS organisations come together to develop and then secure the multi-million pound agreement, having selected Interserve as their preferred provider in September.

Adrian Ringrose, chief executive for Interserve said: “This joined up approach of combining facilities and estates services is the first of its kind in the UK, supporting the efforts of the NHS to shape services around the patient experience.

“As an experienced provider in delivering services in a clinical environment, this is a great opportunity for Interserve to work with the Trusts to redefine their services and their hospitals.”
