Ask for a Special VFR Clearance via Hatton Cross and M25 Junction 14 not above XXXX legal feet.
There will likely still be around 600 movements at EGLL on the 25th so don't hold your breath whilst waiting for a suitable gap in the traffic. Expert that you are I expect you already know that SVFR is not allowed to hinder IFR.

Gatwick can be transitted under VFR at any time of the year.
