Get an independant garage to do it cheaper, Maybe kwik fit do it as well.
Make sure they put new clips on each end of the new boots, and do not reuse the old ones, as they can snap over time. Had clips snap on me on a Vauxhall after 6 years, but luckly was an easy fix with new clips as caught it on time at MOT, no shaft removal required, as CV joint was not contaminated with dirt in the grease.
