London Ambulance Service puts 400 extra crews on the road this week as temperatures soar

London Ambulance Service has put more than 400 extra ambulance crews on the road this week as temperatures are forecast to reach the high 30s across the capital.

Emergency calls linked to the hot weather are increasing, with crews responding to more people who are fainting, struggling to breathe and becoming unwell in the heat.

Chief Executive Jason Killens KAM said:

“This is an exceptional heatwave and the red alert means there is a risk to life, even for people who are normally fit and well.

“We are already very busy and we’re expecting significant pressure over the coming days, with more patients becoming seriously unwell.

“We’ve put more than 400 extra ambulance crews on the road this week to help keep patients safe.

“To help us, please look after yourselves and others. And only call 999 in a life-threatening emergency, so we can be there for patients who need us most.”

The warning comes just weeks after one of the busiest days in the Service’s history. During the last heatwave in May, London Ambulance Service handled more than 8,000 calls to 999 in a single day.

It was the highest level of demand since the height of the Covid pandemic.

Hot weather places direct strain on the body. It can cause people to collapse, struggle to breathe or experience heart problems. It can also worsen existing health conditions.

The Service said it is seeing some patients become seriously unwell very quickly in the heat. Demand also often continues after temperatures begin to fall, as respiratory and heart-related incidents can increase in the days following a heatwave.

As well as extra ambulance crews, London Ambulance Service has increased checks on patients who are waiting for help. This allows clinicians in the 999 control room to identify if a patient’s condition is deteriorating and ensure the most seriously ill are prioritised.

The Service is urging Londoners to take simple steps to stay safe during the hot weather. People should drink plenty of fluids, avoid the sun between 11am and 3pm and keep their homes as cool as possible.

People are also being encouraged to check on neighbours, relatives and friends who may be more vulnerable to the effects of the heat.

People should only call 999 in a life-threatening emergency. Anyone who needs urgent medical advice should use NHS 111 or contact their GP.
