Tea time

A new tradition has begun in our family. Our children are enjoying a daily tea time. We recently went on a shopping trip for a tea pot and tea cups. Each child chose his/her own tea cup. Both boys chose starfish & seashell cups, Hannah chose roses, and Lily chose a feminine one with images of petit fours, flowers, etc. Why a daily tea, you ask? School begins for them in one month. Instead of an after school snack, I thought it would be nice to elevate it to tea time, making it more special, getting them use to using breakable cups carefully, and beginning a sweet new tradition...something for them to look forward to daily. They love it and feel very special. Now, can anyone answer this.... what time is "tea time" in England?
