★★★★★Featured review by sharon agostini

My son has always enjoyed spending time at Cornwallis. The staff are extremely experienced and take pride in their interactions with ALL children. They are firm and fare with regard to the rules and the expected behaviour within their establishment, which reassures me the children are safe and looked after well. Staff are knowledgeable, diverse, fun and caring! Great childcare provider! Definitely would recommend to others!

🏆 Family Action Verdict

An exceptional free resource for school-age children in SE London, particularly those aged 6-11. The staffing quality is far above what the free price point would suggest — children are supervised, engaged, and mixed across backgrounds. After-school drop-in and holiday programmes make it practical for working parents. Not suitable for under-6s.

“This is a fantastic place for your children to come and let off some steam, interact and make new friendships with other children. The adults that work there are so welcoming and make the children feel very comfortable! Its Free!! Which is mindblowing as I would pay good money for this service. Really could not recommend this more.”

“This is the most amazing hidden gem. An adventure playground, indoor area for wet play, fabulous and caring staff and it's all FREE! Our children enjoy going after school for a drop in, and this half term they came home BUZZING after a day of jewellery making, followed by circus training! I can't recommend it highly enough.”
