Firefighters have urged people to stop using barbecues and remove rubbish in open areas to help prevent fires in hot weather - as yet more blazes have broken out.
At least eight hectares of land were affected by a fire declared a major incident on Sunday, at Hankley Common, near Farnham in Surrey, which has previously been used to film part of the James Bond blockbuster Skyfall.
Crews are expected to remain at the scene through Monday.
And fire crews in London had also been battling wildfires - with blazes in Rammey Marsh in Enfield, Cranford Park in Hayes and Thamesmead, all described as "weather related".

Our firefighters & control officers are doing a fantastic job in challenging conditions. Your co-operation will help us greatly."
Surrey Fire Service joined the call. It said: "Speak to young relatives about safety outdoors, pack a picnic instead of a BBQ, dispose of cigarettes and litter correctly."
