Wishing our colleagues and customers a Happy St Patrick's Day from #TeamCAW!

We enjoyed celebrating together in the office yesterday and sharing Tayto crisp sandwiches - enjoy the day however you are spending it!


#TeamCAW enjoyed a bit of #healthycompetition in a Steps to Health challenge this February and participants clocked up 5.5 million steps between them!

Well done to everyone who took part, it's been great to hear how much everyone has enjoyed the #challenge!
