Out of the Dragons Den

Former HETAS Registered Installer David Gattie is fresh out of the Dragons Den and interest in his innovative ventilation product Find out how it went for David in front of the four Dragons and life out of the den.

Why DR21?

Between 2008 and 2016 David was a HETAS registered installer and fitted over a thousand appliances before heading off for retirement.

David always hated putting in the air vent, and if a draught free vent was specified with a 5” diameter hole instead of 4” it was even worse.  Customers also hated the vents and often ended up blocking them up as soon as he completed the job. Many of you will be familiar with this problem.

David wanted to find a solution to overcome his challenged experienced as an installer and this led to DR21.

DR21 Ltd is a family business, based in Knutsford, Cheshire. The product is made entirely in England and is manufactured to ISO 9001:2015 standards. It was independently tested on the 24th October 2016 by BRE and has approval with HETAS.
