Who are Keston Builders Merchant and What is the Brokerage Model?

Keston Builders Merchant isn’t your typical builders’ merchant. We operate as a specialist construction materials brokerage, giving you exclusive access to Tier 1 pricing from every major local merchant and national manufacturer, rates you won’t get on your own.

We shop around your material requirements, weighing price, lead times, quality, and service to find the best value for your order tailored precisely to your project. You receive a transparent quote from KBM, and once approved, we place the order directly with our trusted suppliers on your behalf.

Your materials are delivered straight to your site, with our dedicated customer service and operations team monitoring every step. If any issues arise, we act fast—switching suppliers instantly to keep your project on track.

We take the stress out of dealing with big merchants, poor communication, and hidden markups, so you get better prices, reliable delivery, and peace of mind every time.

Drylining & Interiors Specialist

Flynn James Ltd


Since partnering with Keston Builders Merchant in January 2024, they have transformed our material management. We’ve saved £75,000 on insulation and dry lining alone — substantial savings that have boosted our project margins. They smoothly transitioned our entire supply chain without disruption, and we’re consistently finding better deals than ever before. Initially, we had concerns about operational reliability, but they haven’t missed a single delivery yet. Their professionalism and efficiency have exceeded our expectations. I would highly recommend Keston Builders Merchant to any construction business looking to optimize costs and streamline procurement

Questions that we are asked most often

How does your brokerage model work?

Unlike traditional merchants, we operate on a procurement-on-demand basis, which means we don’t hold large stocks. This approach keeps our overheads low, allowing us to offer you tighter pricing margins than typical high street merchants.

When you submit an enquiry, we shop your order around the wholesale supply chain to find the best value for your project. For fast turnaround jobs, we use pre-negotiated agreements with almost every major merchant in the industry, enabling us to secure next-day deals at tier one rates.

Because you don’t have credit accounts with our suppliers, we purchase the materials on your behalf from the most competitive sources and arrange delivery directly to your site. You then receive an invoice from us at the agreed prices, effectively using our credit line and gaining seamless access to supplier networks and pricing that wouldn’t be available otherwise.
