I have contacted a local company that I thought were trade and would have some good prices, I asked them the question about ply and received this response
They will also offer delivery which was £20ea.... Im not sure if that was each delivery required or each sheet.... No way i'd be paying £38.92 + vat for a sheet and adding £20 delivery to it too..... I can rent a van for £25 a day, and drive a van everyday for a living (racked out and tracked so cant use that) ***Above prices do not include VAT @ 20% ***Thanks for the enquiry, we are pleased to be able to offer the following options:
12mm Latvian Birch Plywood 1220x2440mm BB EN636-2 FSC - £38.92ea
12mm Wisa Finnish Softwood PEFC 2440x1220mm EN636-2 Ext - £25.04ea
12mm Chinese Softwood Pine CDX 2440x1220mm EN636-2 Ext - £17.50ea
12mmx2440x1220mm Chinese Hardwood Throughout / Far Eastern EN636-2 Ext - £22.28ea
Another timber merchant has the following on the website
Are these prices sounding about right....? seems a little dear to me...!Birch plywood throughout with B/BB faces. Even though bonded with WBP glue it is not intended for exterior use or areas of high humidity
£41.95 (based on 8x4 sheet)
