When the Doherty family found out they had scooped £14million in the lottery, they celebrated by ordering Hawaiian pizza from Domino’s for £45.
And John reckons he will continue working as a plumber despite the big win.
He said: “I enjoy my work and I’ve been doing it for 33 years.
“I’ve got a lot of customers that I’m loyal to and I basically work by myself as a subcontractor.
“At the moment, I’m going to carry on with it and it would be very hard to give it up.
“I enjoy what I do and I’ve been enjoying it for a long time.
“I was back at work yesterday (Monday) so it really brings you down to earth.”
John and Alison have two children, Ryan, 20, and Laura, 11.
Ryan, a third year student of Psychology at Heriot-Watt University in Edinburgh, asked his parents if he could get a new car.
He said: “At first I was completely mind-blown and couldn’t get my head around it at all.
“But the next thing that came into my head was ‘oh my God, I could get a new car’.
“I was initially joking but then it came into my head that I actually could.
“I have a little Ford Fiesta at the moment but I’m looking for a wee upgrade.
“I think me and my mum have a bit of difference in opinion over what I should get.
“She doesn’t think I should get anything too flashy or powerful but I’m thinking something more flashy and powerful.
“I found out just before we went away on holiday. I’m surprised that I managed to keep it a secret for so long. I don’t know how I managed but I did.
“It’s not going to change me in any way. I’ll still shop at ASDA and I’ll keep living with my friends in a flat.”
Alison is a former classroom assistant at Kilbarchan Primary School and John runs JDPS Plumbing Services in Renfrewshire.
The couple met when they were working in a Jaconelli’s ice cream van as teenagers and celebrated their silver wedding anniversary this year.
They have lived together in their four bedroom house for over 20 years.
