Shipping a side table to London

I need to ship a side table, weight 18 kg (+ packing) and size 50 x 50 x 50 cm. What company would offer the best rates to do this? Eurostar first luggage delivery has a rate for 1 extra large box £58.49, and 5 days transit. Pick up & delivery door-to-door. Does anyone have experience with this company? I'm estimating arrival 2 days before the latest my item has to arrive, just in case. Good, bad reviews? Any other companies you can recommend?
