Extreme Heat: Resilience of NHS Infrastructure

Viscount Stansgate Excerpts

Tuesday 30th June 2026 Lords Chamber

[Baroness Merron (Lab)]

Yes indeed, and I go back to my point about the £6.75 billion estates safety fund, the whole intention of which is to target the most serious risks, such as those the noble Baroness refers to. Vital projects will attract that funding. They include overheating risks such as broken chillers, outdated air-handling units and, if needed, refrigeration—in other words, where there is a need for urgent upgrades.

[Viscount Stansgate (Lab)]

My Lords, last night, here in the House, the Parliamentary and Scientific Committee, of which I am president, held a meeting on the effects of extreme heat in the workplace. During that meeting, reference was made to the fact that, during last week’s heatwave, several MRI machines failed. Will my noble friend extend an invitation to the Physiological Society, which has done a great deal of work on the effects of heat on the human body, and consult it on possible ways these types of events can be avoided?

[Baroness Merron (Lab)]

My noble friend raises an important point. It is important to note that extreme heat particularly affects buildings with poor insulation and limited natural ventilation, which, by their very nature—I am describing many health settings—heavily rely on such measures if there is heat-generating equipment like imaging suites and IT systems. Also, 11% of buildings in the NHS estate are older than the NHS itself, which gives some sense of the scale. We have committed £10.5 million in research funding to develop effective cooling solutions that can be used across the whole system. It may well be that the organisation to which my noble friend refers is part of that, but I will take his suggestion back to the department.
