The knock on the door from Andi Peters came at around 9.30am on Friday at an address in Wolverhampton and was part of the Wake up a Winner competition on the Lorraine show on ITV.
The presenter knocked on the door, which was said to be in a "secret location", and after meeting the husband Rob first, was greeted by a visibly emotional Helen, who was in the middle of a work meeting.
He then announced she was the winner of £10,000, which was followed with ticker tape, and questions to a clearly overwhelmed Helen about what she was going to spend the money on.
After taking time to compose herself, she said the money would come in handy for her two children and a possible family holiday.
She said: "It's just going to make a massive difference as we've got both girls birthdays this month and the eldest is going to university.
"We've also got family in New York, so hopefully we'll be able to go."
Andi Peters also asked Rob if he had known that Helen was entering the competition, with Rob saying: "Not a clue, as we work at home on Fridays in different parts of the house, so she could have been doing anything."
