What Vaillant does

Vaillant is the UK operating arm of the German family-owned Vaillant Group, a 150-year-old manufacturer of residential heating, cooling, and hot-water technology. The company designs and supplies high-efficiency gas boilers (ecoTEC plus, exclusive, pro, ecoFIT pure), air source heat pumps (aroTHERM plus, aroTHERM split, flexoTHERM) using low-GWP R290 propane refrigerant, smart connected controls (sensoCOMFORT, sensoHOME, myVAILLANT connect), and uniSTOR hot-water cylinders. Underlying technology includes high-efficiency condensing boiler engineering, propane refrigerant heat-pump systems, and connected thermostats with weather compensation, supported by 8 global R&D centres and up to 499 quality checks per unit.

The business model combines hardware sales (boilers, heat pumps, controls, cylinders) with an after-sales service stream (annual servicing, repairs, Cover & Care packages, and a recently introduced Smart Home Subscription). Go-to-market is overwhelmingly indirect: Vaillant sells primarily through a national network of Gas Safe registered installers accessed via its Find an Installer tool and the Vaillant Advanced installer loyalty programme, with consumer leads generated through vaillant.co.uk and routed via partner RIPPL to roughly three installers per enquiry. A direct Time Expired Replacement Service supplements the channel, with consumer financing through Novuna and payment processing via Worldpay/FIS. UK headquarters and award-winning green-powered production are based in Belper, Derbyshire; the ultimate parent Vaillant GmbH is headquartered in Remscheid, Germany, with the group operating 10 production sites and serving customers in 60+ countries.
