The UK Health Security Agency has increased its heat health warning from level three to level four - a "national emergency".
Level four is reached "when a heatwave is so severe and/or prolonged that its effects extend outside the health and social care system... At this level, illness and death may occur among the fit and healthy, and not just in high-risk groups," it said.
The Met Office red warning, for Monday and Tuesday, covers an area from London up to Manchester, and up to the Vale of York.
