Water Softener Salt

‘It’s so pure you could put it on your fish and chips!’  Poltrade DIY stock Granular & Tablet Salt –

Here at Polytrade DIY we’ve gone to great lengths to ensure we only promote and sell the highest purity and quality salt, that is also from a truly eco-friendly source.

As a family run DIY shop;  reliability, quality and tradition, is an important part of every DIY product that we sell. We firmly believe that the DIY products we sell reflect on who we are. So, when we came to sourcing our salt supplier, we wanted to work with like-minded people to ensure we achieve the perfect blend between quality and tradition. We chose Monarch as they are by chance also a local company and this helps with the ecological footprint.

All Monarch water softener salt is classified as Food Grade Salt tested to BS:EN 973 Class A requirements and complies with the European Chemicals Agency EU: 528/2012 biocidal test criteria.

What our customers say

Excellent (10/10)

I had got quotes for Windows & Doors from other companies in Diss and they were all about the same. I called Polytrade who were a little cheaper but the guys were so helpful. Really can't fault them, will use again.

Very helpful staff and good quality building supplies at a very competitive price.

Good stock and nice people to deal with.
