The hottest summer on record has ended in a deluge as Britons battle a torrent of showers and are warned their homes could be at risk of flooding.

The Met Office has issued an expanded yellow warning this morning for London and the south east of England with up to 70mm (2.8in) of heavy rain set to fall up to 12pm.

As the end of August looks set to be a washout, this could be accompanied by 'the odd rumbles of thunder'.

But there has been no change to the three hosepipe bans in place across the UK despite the three inches of deluge.

Thames Water asked 1.1million customers not to use hosepipes, including for cleaning cars, watering plants, filling pools or cleaning windows.
