Welcome to British Swim School of Flatirons


British Swim School of Flatirons is now offering our parent-trusted, kid-loved, and time-tested water safety & swim lessons to our Denver, Boulder, Arvada and Westminster families as well as surrounding areas. With convenient locations, we can find a schedule that works for you.


Drowning is the leading cause of death among children ages 1 – 10. British Swim School’s mission is to help prevent these tragic deaths with a two-step curriculum that teaches children and adults water safety survival skills first and swimming skill development second.


Research shows that participation in formal swim programs such as British Swim School can reduce the risk of drowning by 88 percent among children who are most at risk for deaths caused by drowning.


At British Swim School, we’ve been trusted by families for over 40 years, thanks to our…

  • Individualistic approach – We get to know our students and families on a personal level, enjoying relationships that can last for years.
  • Highly-Trained, Child-Friendly Instructors – We don’t just select our Instructors based on their skills and professional experience. We also look for character and a caring, fun personality, so that learning is not just safe, but fun, for your child.
  • Warm Water! – Our pools are warm. So, you won’t hear complaints of ‘I’m cold’. Kids love our pools; we hold classes year-round.
  • Year Round, Ongoing Enrollment – You don’t have to wait for the school term to start before you enroll. We welcome children and families at any time! No need to wait for the next session to start or lose progress by starting over!
  • Small Classes – We keep our classes small, so that your child gets the individual attention that he or she needs and deserves.
  • All Ages – All-Inclusive – We teach babies from as young as 3 months old, right up to adults. We’re also trained to teach children and adults with special needs.

Everyone deserves to have fun in the water, learn how to swim, and learn survival techniques that will serve them their entire life.
