Overview

• The heatwave is forecast to continue until July 15 with temperatures regularly exceeding 32°C.
• RAC reports breakdowns are up to 20% higher than typical for July, causing longer wait times for roadside assistance.
• Insurers warn that high temperatures accelerate chemical reactions in batteries, leading to faster discharge and reduced lifespan that makes flat batteries the top cause of breakdowns.
• Replacing a worn car battery costs between £50 and £300 depending on the type, and drivers are encouraged to swap units older than three years.
• Experts advise motorists to check oil and coolant levels, tyre pressure and tread before trips and to carry water, sunscreen and shade provisions during long drives.
