You cannot collect your car outside of these hours, although some depots will allow out of hours returns. However, if you do return your rental car out of hours, you are still liable for any damage, until depot opens.
Apart from the major airports, all Alamo, National and Europcar depots are closed on bank holidays, and as most depots do not have drop boxes, then car has to be returned when depot open.
If booking car rental in London for Xmas, then it may be cheaper to return the car to an airport, and pay the extra one way fee.
