Matt Tulley, redevelopment director at Imperial College Healthcare NHS Trust, said the facilities at St Mary’s Hospital were “no longer fit for purpose”.

“Despite spending millions of pounds every year on maintenance, we can’t keep up with the rate of deterioration, which is why we are now seeing an increase in major building failures,” he said.

“We urgently need a new hospital, and we now have a once-in-a-generation opportunity to secure a future-proofed, landmark facility alongside wider regeneration that will bring even wider benefits for local communities.”

A second round of consultations has opened, following a first round earlier this year, with the trust aiming to submit a planning application in spring 2027.

If approved, construction may begin by 2030 and completion may be possible by 2035.
