GOSH appoints Dalkia, Sisk and BDP for £300m Children’s Cancer Centre MEP works

Great Ormond Street Hospital has taken a major step forward with its planned £300m Children’s Cancer Centre after Dalkia agreed a partnership with Sisk and BDP to deliver the mechanical, electrical and public health works. It is a significant healthcare package for one of the UK’s best-known hospitals, and it underlines how important specialist engineering is in a live clinical environment.

Project overview

Great Ormond Street Hospital’s Children’s Cancer Centre is one of the most important healthcare schemes currently moving through the UK pipeline. The project is expected to deliver a major new clinical facility in central London, with MEP works forming a core part of its delivery.

The scheme is especially notable because it combines high-value healthcare construction with the technical demands of a specialist children’s cancer treatment environment. That means the building services are not just supporting the project; they are central to the way the facility will function.

Delivery partners and key stakeholders

Dalkia is taking responsibility for the MEP side of the project, bringing specialist engineering expertise to a highly complex hospital scheme. Sisk is part of the delivery team as main contractor, while BDP is contributing design input and technical coordination.

That combination is important because hospital projects depend on close collaboration between contractor, engineer and designer from the start. In a scheme like this, the success of the building depends on how well the team can align design intent, clinical requirements and construction delivery.

Great Ormond Street Hospital is the long-term operator and end user of the building. Its clinical teams, patients and operational staff will shape the way the centre performs in practice, so the project has to be built around real healthcare needs rather than purely architectural ambition.

Construction and technical details

The MEP package is one of the most critical parts of any modern hospital project. Mechanical systems handle ventilation, temperature control and air quality. Electrical systems provide power, lighting, emergency resilience and support for specialist equipment. Public health systems cover water, drainage and wider building safety functions.

In a children’s cancer centre, those systems become even more important. The facility will need to support highly sensitive clinical spaces, strict performance standards and long-term operational reliability. That means resilience, maintainability and sequencing will all be crucial throughout the build.

The fact that this is a live hospital setting adds another layer of complexity. Construction teams will need to manage disruption carefully, maintain safety standards and coordinate closely with hospital operations. That is one of the reasons hospital projects are so demanding, and also why specialist MEP contractors are so valuable on schemes like this.

Why it matters

This project matters because Great Ormond Street Hospital is one of the most recognised specialist hospitals in the country. Any major investment there is going to attract attention, both because of the clinical importance of the site and because of the construction complexity involved.

It also matters because healthcare remains one of the strongest and most technically demanding sectors in UK construction. Large hospital schemes continue to generate significant opportunities for contractors, consultants and specialist engineers with the right experience. In particular, MEP packages remain central to project success because they determine how the building will perform over its lifetime.

The project also creates opportunities beyond the headline contract. Commissioning, controls, specialist systems, maintenance planning and phased integration all tend to become part of the wider delivery picture on hospital schemes. That means the project can support a much broader supply chain than just the core delivery team.

Construction market angle

From a market perspective, this is the kind of project that strengthens the reputation of everyone involved. A major GOSH scheme carries weight because it demonstrates the ability to operate in a technically demanding, high-profile and highly sensitive environment.

The partnership structure also suggests a joined-up approach rather than a fragmented delivery model. That is usually a positive sign on a healthcare scheme, where long-term performance matters just as much as initial construction. Hospitals do not just need buildings that look complete; they need buildings that work reliably every day.

For the wider construction industry, this is another reminder that healthcare remains a strategic opportunity sector. The projects are complex and exacting, but they reward firms that can combine technical competence with discipline, coordination and delivery certainty.

Writer’s opinion

This feels like the right kind of team for a project of this scale and importance. Great Ormond Street Hospital does not need a flashy delivery story; it needs a dependable one. In a scheme where building services are so central to performance, the quality of the technical team is just as important as the size of the investment.

What stands out most is the role of the MEP package. It may not be the most visible part of the project from the outside, but it is one of the most critical. In a children’s cancer centre, those systems help shape the environment in which treatment happens, so they carry real operational and clinical significance.

There is also a wider industry lesson here. Healthcare construction continues to reward contractors who understand that delivery is about more than structure and finishes. It is about systems, resilience and long-term usability. That is why projects like this remain so important in the UK market.
