Ryan McWilliams, 37, was the lucky winner out of more than 100 entries in tado°’s Christmas installers promotion and has been given £500 to spend through the company’s Professional programme.

Installers were entered into the prize draw whenever they bought a wireless or wired Smart Thermostat, Smart Radiator Thermostat 4-pack or additional Smart Thermostat between December 1 and 20 from participating partners.

Ryan, a father of two boys aged 8 and 11, had only joined tado°’s Professional platform for installers a month ago, after a 20-year career in the industry, and said: “This has come completely out of the blue.

“I did not realise that I was registered for a promotion until I got the call that I had won a few days before Christmas.”
