Kempton Steam Museum Kempton Steam Museum – home of the world's largest working triple-expansion steam engine

Kempton is home to one of the world's largest working triple expansion steam engines, one of two commissioned in 1929 to pump water 24 hours a day, 7 days a week, to North & East London. The engines are housed in a magnificent Grade II listed Scheduled Monument and are open to the public on advertised dates. See events page or our website for a list of our static open days and steaming weekends.

It’s nearly time to power up the Sir William Prescott Engine and we hope you’ll join us on Saturday October 17th and Sunday October 18th to revel in living, breathing engineering history!

Almost 100 years old, the Sir William Prescott Engine at Kempton Steam Museum is the world’s largest working triple expansion steam engine, once pumping 19 million gallons of London’s drinking water every day.

Book a guided tour of the engine's twin, the Lady Bessie Prescott Engine, currently being lovingly restored by Kempton’s team of wonderful volunteer engineers.

Located with the Kempton Park Waterworks in southwest London, you’ll find us just off the A316. There’s plenty of parking, tea, cake and 800 tonnes of precision engineering in action.

About last night… 💛

To honour our local Feltham hero, Freddie Mercury, we were joined by the sensational .queen.tribute and 150 ticket holders to mark what would have been his 80th birthday, and 35 years since we lost him.

Thank you to everyone who made the air electric and to every one of our volunteers that keep our museum and engine running. We had ourselves a real good time 🎸

Behind the scenes, our incredible volunteers get everything ready for steam. 💨⚙️🧑🏻‍🔧

From prepping the engines to making sure every detail is just right, there’s a huge amount of work that happens before the pumps begin, and the steam rises. Their dedication keeps the engines running and helps make our steaming weekends & special events possible.

Kempton played a vital role in transforming London’s water supply, helping deliver clean drinking water to a rapidly growing city. It’s a story of engineering, public health, and the people who built the infrastructure that millions still depend on today.

If you’d like to dive deeper, visit our website to explore the history of the pumping station, the people behind it, and the remarkable machines that made it all possible.

Better still, come and experience it for yourself.

At Kempton Steam Museum, you’re not just looking at old machinery, you’re standing beside some of the largest working steam engines ever built. Our engines aren’t static museum exhibits; they’re living machines that still run on steaming days, bringing this extraordinary chapter of London’s history to life in a way few places in the world can.

Whether you’re fascinated by engineering, London’s history, or simply want to witness these incredible machines in action, there’s nothing quite like seeing, and hearing, them for yourself.

📍 Visit the museum, explore our collection, and discover one of London’s greatest hidden engineering landmarks.
