Extra costs at LU per year?

[WEMum]

We are very lucky to receive the offer from Lu & GL. We're kind of get our minds set for LU mainly due to co-ed and cheaper tuition fees. We are not in a very rich family with both parents in full time jobs and two kids to feed. Just want to have some ideas about the extra costs at LU. I know we need to pay for trips, uniforms. text books and music lessons. How about sports games and clubs? How much in total per year?
Many thanks

We were at the offer's event last night. DD was quite temping to do swimming and rowing. She loves swimming the best out of all sports. I just wonder if we need to pay extra for her to swim or rowing?

Only extras are for trips ( including the main ‘activities week’ one), uniform and private music lessons/ LAMDA. Not text books.
No extra charges for sports etc unless she wanted to do a course in the holidays. They don’t do rowing until y9 but in y8 can do a taster week in the summer holidays which costs money etc. Rowing in games lessons is all included.

@hollibobs22, Thanks a lot. That's affordable then. And hopefully it stays that way. It's such a big financial commitment.
