You could consider giving him a gift basket filled with his favorite British snacks and treats like shortbread, crumpets, English breakfast tea, digestive biscuits, Walker's crisps, and some imported Cadbury chocolates. Another idea could be to take him to a British pub for a meal or cook up a traditional British dinner at home, complete with bangers and mash or fish and chips. You could also look into getting him a cookbook featuring British cuisine so he can try out new recipes at home.
Or you can get him a star map with the date when he was born.
