When Paul couldn't get an answer at the door he looked through the kitchen window and saw the lady, who is in her 70s, on the floor.
Fifty-four-year-old Paul and a neighbour managed to get into the house and comforted the lady until a family member and paramedics arrived to check her over.
When Paul had finished his deliveries he even popped round to see if the lady was okay and, after he heard that she'd made a quick recovery, he was thanked by grateful members of her family for his help.
Store manager Anthony Tranter has nominated Paul, who's worked at the store for three years, for an Asda service superstar award. Anthony said the whole store was proud of him for his quick thinking.
Anthony said: "Drivers like Paul really are unsung heroes. If he hadn't had seen her when he did the situation could have been much worse.
"He is a very caring person who knows his customers inside and out and that's why he knew something was wrong when she didn't answer the door. He's very passionate about his job and the customer always comes first. We are so lucky to have him on our team."
