In Carshalton Beeches there’s a network of bridleways and stables to keep your own horse (doesn’t sound like you’ll have the time?) and generally quite a few horses that I see in the fields around here. For going on weekend hacks in the countryside or your son learning to ride, you’d be looking at a 10-min drive out as there are stables that organise that sort of stuff.
Other activities around Carshalton Beeches/South Sutton/Cheam Village-South Cheam are golf, bouldering, lots of tennis clubs, rugby, cricket, there’s a David Lloyd in Cheam Village (lots for kids) and lots of other things (ballet, dance, trampolining and gymnastics etc).
Carshalton Beeches has trains into London Bridge and slow Victoria trains (faster trains from Carshalton Station + Thameslink via City Thameslink). Sutton is on all those lines and Cheam has Victoria and London Bridge trains. It’s also a short bus ride/Uber from the tube on the rare occasion you stay out till 3am. All stations are zone 5 and it’s a 15-20 min drive to Wimbledon Village for a bit of ‘Londonness’ and fancy shopping.
Generally a brilliant area to live if you sort of want to be in London but sort of out of it (which was our conundrum).

State schools are as good as they get and there’s a wide selection of indies, too.
