Vaillant Secures Willmott Dixon Specification

Vaillant UK has signed an agreement with Willmott Dixon Construction, the construction and interior fit-out specialist that works across all sectors of the construction market, including education, health, leisure, residential, hotels, law, and offices.

The contract means Vaillant is mandated as sole supplier for Willmott Dixon Construction’s domestic gas boilers, which will be fitted in the new build residential sector of their business portfolio. Willmott Dixon was keen to standardise the specification for the boilers they use in their homes, as well as for the many larger projects and applications across the country. Vaillant secured the contract following an exhaustive tender process and a visit by Willmott Dixon’s team to Vaillant Industrial, the award-winning manufacturing plant in Belper, Derbyshire that produces over 300,000 boilers per year for the UK market.

Vaillant’s Which? Best Buy range of boilers has long been recognised as the engineer’s choice, offering highly efficient performance whilst being easy to access for maintenance and servicing. Alongside the comprehensive range of boilers for which it’s best known, Vaillant also offers an increasing selection of heat pumps as it looks to the future for heating requirements with appliances that aren’t reliant on fossil fuels. Vaillant’s newly launched aroTHERM plus air-to-water heat pump is real game changer in this market: beautifully designed and incredibly efficient, it’s the first heat pump in Vaillant’s offering that uses a natural refrigerant to deliver higher flow rates while having a Global Warming Potential (GWP)* of just three.

Steve Cipriano, Commercial Director, Key Accounts at Vaillant said, “We’re delighted that Willmott Dixon made this specification decision based on ensuring they provide the best quality heating systems for their customers. It’s never been more important to provide the most efficient appliances for their discerning customers, and we have demonstrated that we can supply the right boilers that deliver the performance expected in new homes.”

Gary Johnston, Senior Supply Chain Coordinator (Products) at Willmott Dixon Construction commented, “We were very impressed with the quality of the products that Vaillant manufactures. By visiting their factory, we were able to see their impressive facilities for producing these outstanding boilers. Vaillant`s relentless focus on achieving industry leading quality in their boilers aligns perfectly with Willmott Dixon`s own desire to ‘astonish our customers’ and to ‘build lives less ordinary’.“
