Extreme Heat: Resilience of NHS Infrastructure

Lord Kamall Excerpts

Tuesday 30th June 2026 Lords Chamber

[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.

[Lord Kamall (Con)]

My Lords, I am grateful to the Minister for answering the Question of the noble Earl, Lord Russell, on new-build hospitals, but there is clearly a question about existing hospitals and facilities. I wonder what plan or strategy there is, and whether it is written down, to identify hospitals that do critical and time-sensitive procedures, to make sure that they are prioritised when there are extreme heat conditions, and to commission independent hospitals with the appropriate cooling and ventilation systems to allow those critical operations to go ahead.

[Baroness Merron (Lab)]

We are already investing some £30 billion of capital across the NHS estate. I have mentioned the most serious infrastructure risks, which the noble Lord rightly refers to. While we accept the age of the estate and its size—I noted in preparing for this Question that we are talking about the equivalent of 4,000 football pitches—we also have a backlog of maintenance issues, which have grown and grown. We estimate that some £15.9 billion is needed. While there are no easy solutions, we do have a resilience plan not just for overheating but for all threats to resilience arising from temperature. We are also providing the funding—although, to the point the noble Lord makes, it is down to local decision-making—and ensuring that we are assisting the estate across the country to meet the challenges, the priority being those areas that need it most.
