A B777 flight crew reported encountering wake turbulence from a preceding B777 on arrival at egll. The captain hand flew slightly high on the glideslope to avoid the preceeding aircrafts' wake and in the process a slightly delayed landing configuration occurred.

Narrative:
On approach to runway 9L in egll; we were sequenced behind a B777. On descent we experienced some wing tip turbulence. Our airplane was coupled to the ILS and on assigned speed. Separation was 6.5 NM according to the tower. The disruption continued and I contemplated a go-around. Since we were VFR (clear and unlimited visibility); I decided to disengage the auto-pilot and hand fly the glideslope 1/2 dot high to remain over the preceding aircraft's turbulence. The ride was much better; so I continued the approach to landing. We extended the gear handle at about 1;400 ft and extended the flaps. We landed within the first 3;000 ft; on speed.
