British Swim School - Flatirons

British Swim School - Flatirons Survival and Learn-to-Swim for ages 3 months to adult. Year-round, indoor, heated pools.

British Swim School’s unique teaching methods focus on teaching water safety and swim skills in a fun and gentle manner. Our lessons are taught in a cozy, indoor, warm water environment perfectly suited for our small classes. We feel children learn better this way, so you’ll hear singing and silliness and see lots of smiles! On-going enrollment for our unique survival and learn-to-swim programs is available for toddlers, children, adults, and people with special needs.

Today, we recognize Juneteenth and reflect on the importance of inclusion, opportunity, and community.

Every swimmer deserves access to life-saving water safety skills in an environment where they feel welcomed, supported, and encouraged. At British Swim School, we are proud to welcome families from all backgrounds while continuing to help create safer, more confident experiences in and around the water for children and families in the communities we serve.

🌊Big shoutout to coaches Sam and Grace for helping one of our adult swimmers Will finish the Ironman 70.3 Boulder! He sent us some kind words below:

“This past Saturday I completed Ironman 70.3 Boulder. I finished the 1.2-mile open water swim portion in about 45 minutes, which is faster than I was expecting. I was very comfortable in the water and had a ton of fun. Thanks to you both for teaching me how to swim, I couldn’t have done it without you!”

Every swim skill builds on the next. 💦

From independent jumps and rollovers to back floats and recovery techniques, swimmers practice core skills designed to help build confident swimmers and stronger water safety foundations over time.

Every lesson is another opportunity to practice, progress, and grow in the water.

🎶 Humpty Dumpty sat on a wall… and helped our little swimmers learn valuable water skills! 💦 In Swimboree, songs and nursery rhymes turn learning into play, helping children build confidence, practice movement in the water, and have fun alongside their grown-up. Sometimes the best learning happens when it feels like a game! ⭐

A look inside our Tadpole lessons. 🐸

Designed for children ages 3 to 36 months, these early parent or guardian-assisted lessons focus on water acclimation, gentle full submersions, and introducing foundational water safety skills through guided instruction and repetition.

Early exposure to the water can help create positive swim experiences from the start.

Some of the sweetest moments in swim lessons happen between the splashes. 💙

From poolside giggles to celebrating progress together, swim buddies make every lesson even more memorable. We love watching friendships grow right alongside new swim skills.

Learning is always a little more fun with friends!

Backstroke practice, but make it Survival Week! 💦🐢 Our Turtle 1 swimmers worked on their backstroke skills while one brave swimmer took on the extra challenge of swimming fully clothed. Building confidence, strength, and real-world water safety skills one stroke at a time! ⭐
