Google Flights is a great tool if you're flexible with routings—
there are over 20 return flights available from London for <£100 for a weeklong trip in July. You mentioned France—Paris is about £100, or for about £20-30 less, some southern Spanish holiday destinations; Malaga, Alicante, and Almeria.
