Spiralling temperatures have seen the South-east put on a level three 'heatwave' alert today.
A warning has been issued by Public Health England for people to protect themselves from the possible health effects of hot weather.
Social and healthcare services were also advised to take specific actions that target high-risk groups.
The level three alert is triggered once the Met Office confirms threshold temperatures for a region have been reached for one day and one night and the forecast for the next day has a greater than 90 per cent chance of reaching the threshold again.
The threshold for South-east is an average of 31°C in the day and 16°C at night.
The tinder-dry conditions have also sparked a warning from the Royal Berkshire Fire and Rescue Service.
It has urged people to never leave barbecues unattended and for smokers not to throw cigarettes out of windows.
