Another delivery from Alter Supplies today. Amazing service even for a relatively small order. Timber and slabs delivered promptly by a very cheery young man! An easy 5* given!

Superb building materials depot, immaculately tidy and well organised place and prices seem decent . Thanks to young storeman ( Craig maybe?) who was very patient with me messing about loading some materials. Would definitely recommend.
