Then your tower is
WRONG and are not carrying out their responsibilities as required by an ATC unit within UK airspace. It is the responsibility of ATC to obtain some form of clearance (even if it is "Remain outside CAS, squawk ####, Contact London control on ###.###"), and not to leave you 'hanging' like they are trying to do. I suggest a call to the ATC supervisor / SATCO at the tower concerned to point this out to them. The reference they need to read is:
UK AIP, ENR 1.1.1, paragraph 4.1.4
Also - why are you filing with Heathrow? ATC / Ops at your airfield (if it's the one mentioned in your location) should be taking it and transmitting it for you?
