Where is the best/cheapest place to buy decking and fencing for delivery to west london?

I'm looking to build a basic lap panel fence and also a small decking area and have found what i need from Wickes but i was wondering if anyone can recommend anywhere cheaper or better for fencing and decking supplies. I don't want any 'kits', just the raw components and somewhere that will deliver as i don't have a van.|||I've just done a deck and the best price I got was from Jewson|||other than phoning around, theres not a great deal in it. wickes have a policy where if you get a better deal anywhere else they will refund difference + extra. see their web site. local woodyards can sometimes offer a deal on 'less than perfect' wood. i seem to recall a wood yard in chiswick that looked ok on passing-lots of 'special offer' signs, not far from b%26amp;q. theres a travis perkins under the a4 by paddington somewhere, they have some good seasonal offers. personaly i'd cut out all the running about and get it from wickes!
