Customer Reviews
Fantastic service and products!
I just got a big order of loft insulation and some treated timber for a garden project, and wow, I'm so impressed! The website was super easy to navigate, and finding everything I needed was a breeze. Delivery was fast too, only 4 days to get to me, and the driver was really helpful. The quality of the timber is great, exactly what I was hoping for. I'm definitely going to recommend them to all my friends who are doing DIY. I will absolutely be shopping here again for future materials!
Good plasterboard
I ordered some standard plasterboard. Delivery took 3 days. Everything arrived in good condition. The quality was as expected, no complaints. Will likely order again for my next project.
Smooth order for building supplies
I placed an order for some cement, sand bags, and decorative gravel for a landscaping job. The ordering process online was pretty straightforward, found everything quickly. Delivery took about a week, which was within their stated lead time, so no surprises there. All the items arrived well-packaged on a single pallet. The quality of the cement and gravel was good for the price I paid. Had a quick question about delivery access and their customer support was helpful when I called. Overall, a solid experience for bulk materials. The drainage pipes I needed weren't listed though.
Building Materials Community Discussion
Share tips, ask questions & help fellow shoppers save more
Can I use a regular discount code if I already have a trade account with them?
I'm looking at their PIR insulation boards. How do they stack up against Celotex or Kingspan in terms of performance and price?
Do they actually deliver to residential addresses? Need some plaster for a DIY job, not a commercial site.
Do they offer any first-time buyer discounts or anything? About to drop a fair bit on insulation and plaster.
Is Building Materials a legit site? Never used them before, usually go to Wickes.
