"WOW! We asked Keiran to come out as the walk-in fridge in our restaurant had broken. He was with us within 10 minutes and then fixed within 20 minutes of arriving. He didn’t once try and charge us for something that wasn’t broken and was a very honest man.
I highly recommend to anyone!!!
Thanks so much"
