West Midlands Ambulance saw a massive increase in 999 calls last weekend due to the hot weather, and they're expecting the same this weekend. Last week they had more than 3000 calls.
East Midlands Ambulance Service says their calls are up 15% on what they would expect from an average day.
The Royal Derby Hospital have put their heatwave plan into action - that means cool rooms are available for 'high risk' patients, temperatures are measured four times a day, and extra water is on hand.
As emergency and social services prepare for the heat there are things you can do to stay cool and enjoy the weather safely.
We could be in for the longest spell of hot weather since 2006 as the heatwave shows no sign of stopping. But why is it different to others?
