Smart Design for Flexibility and Mobile Growth

Responsive design supporting flexibility and mobile growth for Warmteservice to bring the e-commerce platform to the next level through UX.


Warmteservice is an established and successful enterprise in the Netherlands. Focused on the market of installation (central heating, sanitary, electronic systems), Warmteservice operates through 61 physical outlets in the Netherlands. The company caters both the B2C and the B2B market with products and services. Its promises are ‘always close in your area’ and ‘willing to service you in the best way possible’. In half a century Warmteservice saw a steady growth in shops, turnover, margin, customer loyalty and engagement. 

Based on their long-lasting relationship Warmteservice requested SQLI to bring this platform to the next level: to service users better on basis of their changing behavior (increase in mobile usage) and to help Warmteservice to deliver a highly flexible tailor made system.


Warmteservice wants to serve their B2B customers better. The existing e-commerce platform was primarily developed for desktop, while the behavior of the users now is shifting increasingly to mobile. Warmteservice also wanted to be more flexible in their offerings, content and publishing throughout the year.

They needed a smart design system that supported this level of flexibility and that could be easily used by their own in-house online team already in place.


The result is a combination of a condensed strategy phase, consensus by internal stakeholders, a re-design of the platform for optimized mobile use and the co-creative development of a smart design system. By doing this, we empowered the product owner of Warmteservice to act with his in-house online team to work as independent and effective as possible.

The team can use clever tools to make the online offering of Warmteservice fitting to the company’s needs. SQLI facilitated Warmteservice in a self-sufficient and agile way of working, helping to extend their already successful enterprise in the digital field.

“Our customers don’t spend a lot of time in the office. In the data we saw this behavior reflecting in the growing use of mobile devices. We optimized the web-shop for these users by introducing a responsive design and making the product information better accessible on mobile phones. Immediately after the optimization, we noticed our relevant KPIs were improving. More customers interacted and ordered via mobile viewports.”
