The cheapest copy has been sitting unsold at £12.50 for 8 days, so undercutting it will help you shift stock first. That listing is graded LP, mind you—a clean raw copy can justify asking more. The lowest ask has jumped 34.6% from £9.29 since the last check, though the market itself is narrow: your 30-day range is £15.03 to £16.63, and two-thirds of UK stock is played condition, so a Near Mint copy would stand out. Don't bother grading—PSA 10 copies haven't budged in a fortnight, and the return on that spend won't justify it.
