Ilkeston firm Arctic Cabins have been chosen by TV businessman Theo Paphitis as a Small Business Sunday winner this week.
The Sunday hashtag on Twitter was created by Theo to boost interest in small firms.
Louise Jones from the firm said: “Theo has over 400,000 followers so it’s a massive boost for the chosen lucky businesses. After the retweet, I was absolutely thrilled and delighted as our Twitter account took on a life of its own.
“It had already been a great day as I had received an email from the BBC to say that the edition of DIY SOS – The Big Build that we had been involved with will be shown on Friday May 30, earlier than we had anticipated.”
