MKM Building Supplies, the UK’s proper independent builders’ merchant, has launched its first dedicated eCommerce mobile app, giving trade customers and DIYers a quicker and easier way to browse products, manage accounts and place orders straight from their phone or tablet.

Andy Pickup, Digital Director at MKM Building Supplies, said:

“We wanted to create something that genuinely helps our customers day-to-day. Our branches do a brilliant job supporting customers face-to-face, and this gives people another way to get things sorted quickly when they need to.

“It means whether someone is sat in the van and needs to quickly order a few bits, or they are planning the week ahead on a Sunday night and lining up deliveries for the next jobs, they can do it there and then without having to wait.”

Built entirely in-house using React Native, the app marks another step in MKM’s digital growth and comes alongside continued expansion across the business, with eight new branches already opened in 2026.

Built for both trade customers and DIYers, the MKM app allows users to browse their local branch stock, check branch-specific pricing, build baskets and pay invoices in seconds. It gives customers the flexibility to order when it suits them, whether that’s a quick restock from the van between jobs or sorting everything out at home while planning the week ahead.

 

 

Open to all MKM customers, the app can be used by both account holders and guest users. Secure biometric login through Face ID or fingerprint makes signing in quick and simple, while a short welcome flow helps new users get started straight away.

Voice search speeds up product lookups, while dedicated sections for Deals, Clearance and Timber Tally make it easy to find offers and select exact timber cut lengths.

For account customers, the app also brings together a range of useful account management tools in one place. Customers can view and filter orders and invoices, access statements, redeem credit notes and pay single or multiple invoices quickly and securely.

The app has been developed over the past year with input from MKM branches and customers to ensure it reflects how customers use their local MKM branches

Accessibility has also been a key focus. The app meets full AA accessibility standards, helping ensure it remains clear and easy to use for customers working in different environments, including outdoors, in low light or on smaller screens.

Behind the scenes, MKM’s Central Support digital team has integrated analytics and insight tools including GA4, Bloomreach and Fullstory. These will help the business understand how customers use the app and where improvements can be made.
