History & Information

Established in 1989, North West Timber and Builder's Merchants has grown from a single unit to a leading regional supplier to trade, the general public and public sector.

NWTT relocated the group's head office and distribution centre to the current Ashton-in-Makerfield site in 2008, located on the outskirts of Wigan,­ following the sale of the previous premises in Haydock to Tesco plc. 

The purpose built 11 acre site is home to our sales and admi­nis­trative teams, delivery vehicles and boasts bespoke treatment facilities, offering green, brown and clear wood preser­vative treatments.


The Ashton-in-Makerfield site also has the most extensive range of materials (within the group) including:

  • Timbers
  • Aggregates
  • Doors
  • Decking
  • Flags and pavings
  • Joinery Timbers/­MDF/­Hardwoods
  • Plywoods
  • Tools/Tool Hire

With more landscaping, building and timber materials than possible to list, our epitomising trade's one-stop-shop.
