I believe that 3 BA airbus overnight at Glasgow, Edinburgh and Jersey. The majority of the 777 are also away from base overnight. Easyjet also have night stops, maybe about half a dozen. Some of their (Easyjet) early morning arrivals are also on aircraft based elsewhere.
I agree though, there are a lot of might stopping aircraft during the summer. When returning from trips to Paphos which tend to arrive around 2230/2330 or later as you taxi in you can many aircraft parked up for the night. Most stands are used, remote or otherwise.
