My youngest goes to breakfast/after school club while I am at work. It is run by the nursery which is on school premises. It costs me £200 a month which gives me availability from 7:30am to 9am then 3:20pm until 6pm Monday to Friday. I get some of this cost paid for with tax credits.
My DD loves it. There is a big age gap between her and my other children so she has pretty much been an only child and there are no children her age near home. She gets to play with her friends, go on the school computers, do activities and they feed her (although it is just supposed to be a snack she doesn't want dinner most times when she gets home).
I have loved having the security of childcare with no hassle!
They also have a holiday club which is £27 a day (8am to 6pm) and they go out to different places and do all sorts of things I probably wouldn't do with her tbh. Some of this cost can also be covered by tax credits although the amount will be spread over the year so you would have to budget to pay more in the holidays while getting the same amount.
I would recommend it totally especially for kids who are on their own a lot and if you are working. Obviously each club is different so maybe get an idea of what activities they offer.
