A New Dynamic in Floor Systems

Underfloor heating is complex. It just is. Detailed designs, different sub-floors, pipe systems, screeds, manifolds, controls, floor finishes, heat sources - you get the picture. DUO has arrived to trade that complexity for clarity, capability and crucially, co-operation. We deliver big time, on time and every time.

DUO is a balance. The yin of smart design and high-performance products meeting the yang of deep expertise and seamless project management.

We are underfloor.
But we are so, so much more.

Floor Systems in The Round

We marry the energy and enthusiasm of a start-up with formidable experience gained over three decades of hands-on involvement: designing systems, consulting on major projects, partnering with leading contractors and installing on the money.

As fresh and eager as we are, we come to market backed by the Broadsword Group. It pairs our underfloor nous with their pedigree and resources in commercial construction across sectors and across services including screeding, dry lining, interiors and fire protection.

Partnership is at our heart - hence DUO. And the ones with our customers are key. We get close and stay close. We communicate clearly and we shoulder responsibility and risk. No corners cut. No empty promises. No balls dropped. Just compliant quality you can trust - in design, products, installation, commissioning and aftercare.

Together with DUO

If we are about anything, it’s partnerships – we are called DUO after all. Service driven and product obsessed, we have secured robust partnerships with industry-leading manufacturers so that we can flex our recommendations and create the best solution for your floor, budget and specification.

We had our underfloor heating serviced as we had just moved into our property. John was great, he serviced our heating then took time out to explain how it works & how to use it. We will definitely be using this company again!
