London Museum of Water & Steam
What Visitors Say
Fantastic museum! I enjoyed it very much to see and hear these beautiful machines on a steam up day (check website for these special dates). Very friendly and knowledgable staff 🤓
A wonderful museum, particularly for those interested in industrial heritage and steam engines. To see and hear these magnificent, historic machines in motion on a steam up day is just fantastic. There's also lots to see in the informative static displays. The staff and volunteers are very friendly and helpful. Can't recommend it highly enough.
Went there with my children they very liked to see giant steam engines and learned how they were working and pumping the water to the city. Not for only children also good for adults. There is a different world under the building I wish I could have seen this part it would be wonderful.
It is a great place to see working history. Staff members were amazing and very helpful. There is something for every age, and if you are with your little one outside, it is a perfect spot for kids to learn how the water flows are working( just look for a sunny day, it's wet and fun). Also, i will recommend checking in advance the website for additional information on the steam train.
Absolute gem! We loved our visit here! The day we visited was a 'steam up' day so all the incredible engines and pumps were working, including a steam melody maker! Little steam train running for the kiddies too. All the volunteer staff very knowledgeable and happy to answer questions. Great displays educating about water supply, disease, greedy utility owners ... all very thought provoking

Fun Facts
The museum’s 90-inch engine has a piston nearly 7.5 feet across—built to lift millions of gallons a day with elegant economy.
Before sand filtration and steam-powered pumping scaled up, London’s water system helped cholera spread rather than stop it.
On ‘Steam Up’ days, engines are started by hand signals and routine older than radio—an operating ballet preserved by volunteers.
