Conservatory owners planning on making the most of the hot weather predicted this week should take care not to overheat after the Met Office changed its prediction on the likelihood of heat wave conditions.
While last week the organisation in charge of forecasting the nations weather suggested there was a 60 per cent chance of excessive warmth, it has altered that figure to 70 per cent.
Head of health forecasting at the body Wayne Elliot explained it has issued its first heat-health watch alert in three years.
"We have been working closely with the Department for Health to develop this [warning] service, which is aimed at those vulnerable to high temperatures, especially the elderly," he said.
Some areas of England are set to experience daytime temperatures of 30 degrees C, with night time heat unlikely to drop below 18 degrees C.
While the extreme heat is less likely in northern parts of the county, London, the east and south east have a high chance of seeing the warmest weather so far this year.
