EXCLUSIVE: YPO reveals 29 modular construction firms appointed to MMC framework

YPO, the UK’s largest public sector buying organisation, has launched a new Modular Buildings and Modern Methods of Construction (MMC) framework.

The framework has appointed 29 specialist firms to provide off-site, modular solutions for public sector projects, including healthcare builds.

“The framework provides a fully compliant route that eliminates the need for trusts to run their own complex construction procurements. All contractual terms, supplier checks, and regulatory requirements have already been completed, allowing procurement teams to focus on project-specific needs,” Michelle Walker, Head of Procurement Service and Supply Solutions at YPO, told Building Better Healthcare.

Walker said the model reduces the time between identifying a clinical requirement and appointing a delivery partner.

The framework runs over a four year period from 18 March 2026 to 17 March 2030 and covers the UK, Guernsey, Jersey, and the Isle of Man.

According to the award notice listing, there is £500m against every lot but the value "may be shared with other lots.”

How the framework is structured

The framework enables NHS trusts and other public sector organisations to procure modular buildings across health, education, housing and justice settings.

It is organised into lots that distinguish between temporary and permanent modular solutions, allowing buyers to align procurement routes with clinical need, estate strategy and project duration.

“The framework is designed to support a wide spectrum of healthcare buildings, from temporary wards and outpatient units to fully permanent clinical facilities, diagnostics suites, staff welfare areas and specialist healthcare environments,” said Walker.

Temporary modular buildings are suited to short-term capacity pressures, seasonal demand and refurbishment programmes. Permanent solutions are intended for long-term estate investment and integration with existing infrastructure.

“When deciding which route to take, trusts should consider the intended duration of use, clinical compliance requirements, site constraints, funding availability, and whether the ability to relocate or repurpose the building in the future would add operational benefit,” said Walker.

For healthcare, Lot 3 covers the purchase of buildings, while Lot 4 enables hire to support short-term or flexible capacity requirements.

The framework also supports both direct award and further competition, enabling faster mobilisation than traditional tendering.

“The award criteria allowed suppliers to demonstrate their experience in healthcare through case studies and other evidence around specification, project management, logistics, sustainability and factory processes, with a minimum score required for them to be appointable,” said Walker.

Supplier reaction

Health Spaces highlighted the role of off-site construction in delivering projects within operational hospital environments.

“Many of our projects have benefitted from off-site construction methods, allowing us to deliver quickly and efficiently,” Joseph Bonner, Tenders and Bids Associate from Health Spaces, told Building Better Healthcare.

“At Peterborough Hospital, for example, we unlocked a previously inaccessible site for a new urgent treatment centre by lifting modular units over an existing building. Similarly, at James Paget University Hospital, our Concept Ward project demonstrated how volumetric modular solutions can pair single-bed rooms with multi-bed bays, creating flexible, modern clinical spaces.”

The company said the framework supports consistency in procurement standards.

“The requirement for the Common Assessment Standard ensures we are on a level playing field with other providers, while YPO’s dedicated construction team gives practical guidance and support from the outset. This level of collaboration is rarely seen in traditional procurement pathways,” said Bonner.

McAvoy Modular Offsite has also been appointed to the framework.

Ciara McVeigh, Head of BID Management at McAvoy, told Building Better Healthcare feels McAvoy’s appointment to the healthcare specific lots “demonstrates our strength and reliability as a trusted partner to support the NHS and wider public sector with rapidly deployable, future-ready modular healthcare infrastructure”.

“This is the first framework aligned with the Procurement Act 2023 to cover such a wide range of modular building solutions,” McVeigh added.

“This also helps to significantly streamline procurement, which is so important for a sector that is often under pressure to deliver care facilities quickly.”

“We’re proud to be part of this forward-thinking framework, helping the NHS and public sector organisations deliver vital healthcare infrastructure at pace and respond more effectively to the challenges they face,” said McVeigh.

Sustainability focus

Alongside procurement efficiency, the framework aligns with NHS sustainability objectives.

“With a strong emphasis on sustainability, including reduced waste, lower carbon outputs, and the ability to reconfigure or relocate buildings, the framework aligns closely with NHS Net Zero priorities,” said Walker.

Modular construction can reduce material waste and carbon emissions, while allowing buildings to be adapted, relocated or reused as service needs change.
