About
Burton upon Trent in the 1880s brewed a very large share of Britain's beer, and brewing on that scale produces an extraordinary quantity of effluent. Added to the sewage of a rapidly growing town, it was more than the River Trent could absorb, and the Corporation built Claymills to deal with it: a pumping station of 1885 designed to lift the town's sewage and brewery waste and send it out to land treatment beyond the built-up area. The scale of the problem dictated the scale of the answer, and the answer was four beam engines.
That is what makes Claymills exceptional. Most surviving Victorian pumping stations preserve one engine, occasionally two. Claymills retains all four of its rotative beam engines, built by Gimson and Company of Leicester, in their original engine houses, together with the boiler house that fed them. The four are complete, in place, and steamed regularly, which is a combination that scarcely exists anywhere else in Britain, and the site is protected accordingly as a monument of national importance.
The engines are only the beginning. The site retains a steam-driven workshop where the belt-driven machine tools still run, a working forge, and a dynamo house of the 1930s containing a Crompton dynamo of the 1890s — the electrical supply that a self-sufficient Victorian works had to generate for itself. Altogether the Trust cares for something in the order of thirty-three steam engines of various kinds, most of them restored by volunteers over decades. The Thompson boilers that raise the steam date from the mid-1930s.
Visiting works on two levels. On static open days the site is free, with guided tours, and the engines can be examined at rest — which is the only way to understand how they are put together. On steaming days, mostly bank holiday weekends, the engines run under steam, and forty tons of ironwork moving almost silently at walking pace is an experience that no static display can approach.
It is, with some justification, rated the leading thing to do in Burton. Few preserved industrial sites in Britain reward a visit as completely, and fewer still let a visitor see the entire installation working as it was designed to.

💡 Visitor Tips
- Decide first whether you want the engines still or moving. Thursdays and Saturdays are free static open days; steaming days are charged and are the only time the engines run.
- Check the Trust's own events page for steaming dates. They are mostly bank holiday weekends, they change every year, and no other source is reliable.
- On free open days, time your arrival for the 11:00 or 13:00 guided tour — the tour is what makes sense of the site.
- Allow far longer than you expect. Two hours is a realistic minimum on a steaming day and enthusiasts routinely spend the whole day.
- Wear old clothes and closed shoes. This is an oily, hot, working engine house, not a gallery.
- The upper beam floors are reached by iron stairs — check the Trust's access statement in advance if that is a problem, though a great deal can be seen at ground level.
- Café facilities are limited and visitors may bring their own food and drink, which on a full-day steaming visit is the sensible option.
- If you have seen Dogdyke Steam Drainage Station in Lincolnshire, Claymills is the same technological moment doing a completely different job — drainage there, sanitation here.
Highlights
The Four Gimson Beam Engines
Four rotative beam engines built by Gimson and Company of Leicester and installed in 1885 remain complete in their original engine houses, which is close to unique in Britain. Beam engines of this class are enormous, slow and astonishingly quiet, transmitting power through a cast-iron beam rocking overhead on a massive masonry entablature.
Standing on the beam floor while one runs, watching forty tons of ironwork reverse direction twice a revolution without apparent effort, conveys something about Victorian engineering that photographs cannot.
That all four survive together, in situ and in steam, is what makes Claymills nationally important. Each engine is named, as beam engines invariably were.
The Boiler House
Steam has to come from somewhere, and the boiler house is where the real work of a steaming day happens. The Thompson boilers now in use date from the mid-1930s, replacing the original plant, and they are hand-fired by volunteers who spend the day shovelling coal in conditions that make plain how physically brutal the job of a Victorian stoker actually was.
Watching the fires being made up, the water level watched and the pressure held steady is the least glamorous and most instructive part of the site.
The coal consumption on a full steaming day is considerable.
The Steam-Driven Workshop
The site retains its workshop with belt-driven machine tools running from overhead line shafting, powered by steam rather than by individual electric motors. This was how every engineering works operated before the 1920s: a single prime mover turning a shaft the length of the building, with each lathe, drill and shaper taking its drive from a flapping leather belt.
Seeing it working restores an entire lost industrial soundscape, and it explains the layout of Victorian workshops in a way that no diagram manages.
The Trust still uses it for restoration work. The belts are guarded now in ways they never were originally.
The Dynamo House
A works of this kind had to generate its own electricity, and the dynamo house of the 1930s contains a Crompton dynamo dating from the 1890s — a survival of the first generation of British electrical engineering, from the years when Crompton was among the pioneers establishing what electric lighting and power supply would actually look like.
It sits at the junction between the age of steam and the age of electricity, and its presence on a steam site makes visible the transition that eventually rendered the beam engines redundant. Crompton machines of this age survive in very small numbers.
Collections
The principal collection is the pumping station itself: four rotative beam engines of 1885 by Gimson and Company of Leicester, complete in their original engine houses, together with the boiler house, its mid-1930s Thompson boilers, a steam-driven workshop with belt-driven line shafting, a working forge, and a dynamo house containing a Crompton dynamo of the 1890s.
Around this core the Trust has assembled and restored some thirty-three steam engines of varied types and sizes, a large proportion of them in working order. Supporting collections cover the engineering of Victorian sewage pumping, the public health history of Burton upon Trent and the effluent problem created by its brewing industry, and the Trust's own decades-long restoration programme.
The site is protected as a monument of national importance and holds museum accreditation.
