Not really, whatever you are jamming you can just make sure it doesn't make it 10 km up in the air where most of the planes are (especially given the GPS patch antenna pointing up from the plane), and I don't believe they need GPS signal on takeoff/landing, they use older tech for that.

Much older. The basic "stack" uses radio beacons, not greatly different from early XX century tech. The more advanced Instrument Landing System is quite a bit more complex, but in very basic terms is a set of radio beacons that define a glide path. It is local, and requires no GPS.

10km up? What about all the planes landing at the other airports of London?

Most of which are geographically distant enough to not be affected by localised jamming.
Never mind that Aircraft will be under ATC in UK airspace, and ATC uses Radar + transponder to localise aircraft.
GPS is a navigational aid, not the primary navigation tool.
