GOSH MEP works partnership: design, decarbonisation and safety notes for engineers
Reviewed by Joe Ashwell

First reported on The Construction Index
30 Second Briefing
Dalkia has partnered with Sisk and BDP to deliver full mechanical, electrical and public health (MEP) services for Great Ormond Street Hospital’s £300m Children’s Cancer Centre, integrating air source heat pumps as the core of the site’s decarbonisation and long-term energy strategy. The MEP programme and construction sequencing are tailored to keep the existing hospital fully operational within its current footprint, limiting service interruptions to advanced clinical and treatment areas. The scheme is set to be the first major healthcare project to pass through the Building Safety Act Gateway process, testing new regulatory and assurance requirements.
Technical Brief
- Dalkia is responsible for installation and commissioning of all MEP systems, not just design support.
- Scope covers building services infrastructure for advanced clinical, general patient care and specialist treatment environments.
- Construction and MEP sequencing are engineered to maintain continuous operation of existing wards within the constrained footprint.
Our Take
Dalkia’s recent appointment to deliver a low‑carbon energy centre for the British Museum suggests its MEP role at Great Ormond Street Hospital is likely to emphasise electrification and heat‑pump‑led systems rather than traditional gas plant, which has implications for resilience planning and maintenance regimes in a paediatric clinical setting.
Within our 840 Infrastructure stories, Dalkia appears increasingly in complex public‑sector refurbishment and energy‑transition roles, signalling that Great Ormond Street Hospital is aligning its back‑of‑house MEP strategy with the same decarbonisation and lifecycle‑cost priorities now seen at cultural and transport estates rather than treating it as a standalone healthcare build.
