Hi Babes
Try searching the internet for cake decorating suppliers and you should come up with quite a few from the UK such as Squires Kitchen, Cake Craft World. There are plenty to choose from.
I live in France and both of these companies will post equipment and icing to you. The only down side is the postage as it usually goes on the weight. I use both of the above companies as well as the Cake Decorating Company and find that delivery is prompt, normally about a week.
Search the internet and the best of luck with you cake decorating.
