Second suggestion is a good one. that's the caterpillar of the Large Elephant Hawk Moth, probably the most frequent "What is this bug?" request in the UK.
As usual the only person who hasn't found one this year is me.
Not quite the only person ... neither have I, although one of the moths came in the bedroom in July - gloriously huge!
