About Us

Lliw Building Supplies Team

Established in 1992 and based in Pontardawe on a 3.5-Acre site on the Alloy Industrial Estate just minutes from junction 45 of the M4 in the scenic Swansea Valley, close to the City of Swansea, the Amman valley and the historic town of Neath.

We offer a complete range of building materials, timber, and roofing products to the building trade, self-build and DIY customers.

Our ethos is to provide you with the best experience when buying building and DIY materials.

We offer a wide range of building materials including bricks, blocks, tiles, drainage, timber and joinery, aggregates and insulation alongside paving slabs, tools, fixings, adhesives, artificial grass and decking.

All of our items, both light-side and heavy-side materials, are available for collection or delivery via one of our small trucks or crane off-load lorries.

We employ over 20 staff to help our customers with their building material needs, and we’re always happy to help:
