Basically, if the seatmap is 1-2-1 it's Club Suites which all seats have aisle access. The vast majority of LHR 777s have Club Suites.
Of course 777 aircraft types can occassionally be changed before your flight but it's not that common really, just something to be aware of. Any more queries do come back and ask.

Going back to this topic (broadly), how far in advance do flights get swapped to the runts of the LHR fleet? Booked in Business back from ATL next August and while I know way too far in advance for anything now, I am aware that the ATL flight often falls foul of a swap to an old CW..
