Here’s mine, ~£300 for 1 in lower secondary school. Probably missed a few things off and will need to top up during the year.
Coat £30 (Vinted)
Shoes £35
1 x PE kit (top, shorts, fleece) £45 (branded)
2 x trousers £34
3 x polos £36 (branded)
2 x sweatshirts £34 (branded)
5 x socks £7
Rucksack £25
Stationery £20
Calculator £15 (specific one needed)
Water bottle £10
Couldn’t have got much of this cheaper unless second hand and even then it costs. Made me think of people with 2-3+ children. Must really add up in 1 go over the summer!
