Jeannie99, I had a Wickes kitchen that had a 10 year guarantee. 9.5 years in and the laminate started to lift and bubble on one door, then another and finally on all of them, including the fronts of the drawers. I telephoned Wickes and was told to photograph each cupboard and drawer and email them to their customer services. Within less than a week, I had 5 new cupboard doors and 4 drawer fronts delivered, free of charge.
If you've still got all your paperwork from when you bought the kitchen, you're home and dry regarding the guarantee.
