Narrative:
Upon arrival to egll after one turn in holding we were given vectors close behind a heavy B747. Initially our turn toward the B747 was closer than three miles. We encountered wake turbulence and stayed about a half dot above the glide slope and we were still very close. We slowed to approach speed approximately 1-2 miles before instructed to do so out of concern for our proximity to the B747. Tower complained that B747 behind us was too close.
