About Us
A family-run business with a passion for quality trade supplies.
Our Story
Plumin Online was launched as an extension of our well-established, family-run business, Roofin Online, which is part of Insullite Limited. For years we have specialised in the manufacture and installation of lightweight roofing systems, serving trade professionals and homeowners across the UK.
Recognising the need for a reliable, competitively-priced online supplier for plumbing and drainage products, we set up Plumin Online to bring the same level of expertise, service and value that our customers have come to expect from Roofin Online.
What We Do
We supply a comprehensive range of plumbing, drainage and heating products from leading manufacturers. Our catalogue covers everything from pipes and fittings through to boilers, pumps, valves, bathroom accessories and much more.
Whether you are a plumber, a builder, a facilities manager or a homeowner undertaking a DIY project, we stock the products you need at prices that make sense.
