A cement mixer is one of those tools that quietly pays for itself. Mixing mortar, concrete and render by hand in a barrow or a mixing tub is slow, hard on the back and almost never gives you a consistent mix from one batch to the next, which shows up later as weak mortar joints and patchy concrete. A mixer turns a barrow of sand, cement and ballast into an even, workable mix in minutes, keeps a bricklayer or a groundworker fed through the day, and holds its value well on the used market. For any job bigger than a bag or two of mortar, it is one of the easier tools to justify.
This guide covers the best cement mixers UK trade and serious DIY buyers are choosing in 2026, electric and petrol, from a compact mixer for small jobs to a trade tip-up drum built for daily use. First, the handful of decisions that shape which one is right for you: drum size, drive type and power source.
Before comparing models, settle three things. On a cement mixer they matter more than the badge or the colour.
Then the practical details that decide how it works day to day:
With those decided, here are our six picks for 2026.
The Belle Minimix 150 is our best overall pick because it is the mixer you see on real building sites, and it is there for good reason. It is a tip-up drum of around 90 litres usable mix built for daily trade use, with the robust frame, steady tipping and dependable drive that a bricklayer or groundworker needs to keep a job fed hour after hour. Belle is the established British name in site mixers, spares and drive belts are easy to find, and the resale value stays strong, which matters on a tool you may keep for a decade. It costs more than a budget mixer, and it is a proper lump to move around, but for a trade buyer who mixes regularly it is the safe, no-regrets choice that earns its keep.

For self-builders, landscapers and DIY buyers taking on an extension, a driveway or a run of garden walls, it mixes mortar and concrete cleanly, tips into a barrow without drama and sits on a sturdy enough frame for the work. It is a direct drive unit built to a price rather than for daily site punishment, so it suits regular project use more than year-round trade mixing, and it is worth keeping it under cover between jobs. For the money, it is a lot of mixer and a sensible first buy. Check the current price on Amazon.
Check price on AmazonThe Charles Bentley 120L is our pick for small jobs because it hits the point where a mixer stops being a luxury and starts saving your back, without the size or cost of a full trade unit. A 120 litre drum is ideal for fence posts, small repairs, bedding slabs, pointing mixes and light building work around the house and garden, and it is light enough for one person to move and store in a normal garage or shed. It is a direct drive domestic mixer rather than a site workhorse, so it is best treated to lighter, regular mixes rather than all-day heavy concrete, but for a homeowner or a handyman it covers the jobs that come up most. For occasional building and garden work, it is a tidy, affordable choice. Check the current price on Amazon.
Check price on AmazonThe T-Mech 140L is our best mid-size all-rounder because a 140 litre drum sits right in the sweet spot between the compact domestic mixers and the heavy trade units. It gives a genuinely useful barrow load per mix for general building, bricklaying and a typical extension, on a frame and wheels designed for one person to move and tip, at a price that undercuts the premium brands. It is aimed at keen DIY and lighter trade use rather than daily commercial punishment, so like any value mixer it rewards being looked after and stored dry, but for someone taking on a substantial project it is a capable, well-sized workhorse. For general building on a sensible budget, it is a strong pick. Check the current price on Amazon.
Check price on AmazonA Belle petrol cement mixer is our pick for off-grid work because some jobs simply have no power nearby. On groundwork, rural sites, new plots before the supply is in and extensions far from a socket, a petrol mixer lets you keep mixing where an electric unit and a trailing lead would be a non-starter. Belle pairs its proven site drum with a petrol engine, usually driving a larger capacity for bigger pours, with the robust build and spares backing that make it a long-term tool. The trade offs are the ones you expect from petrol: more noise, fuel and routine engine maintenance, and a higher price. But for a groundworker or a builder who regularly works away from power, it is the mixer that keeps the job moving. Check the current price on Amazon.
Check price on AmazonA compact portable mixer of around 63 litres is our pick for tight spaces and small loads, where a full-size drum is more than the job needs. For small repairs, potting and planting mixes, grout, small batches of mortar and jobs up ladders or in back gardens with awkward access, a light portable mixer that one person can carry and set up quickly is genuinely handy. It will not feed a bricklayer all day and the small drum means more frequent mixing on a big job, so treat it as the right tool for little and often rather than heavy pours. For a homeowner with ongoing small jobs, or as a second mixer for awkward spots, it is a practical, low-cost buy. Check the current price on Amazon.

Start with the size of mix you need most often, not the biggest job you can imagine. For repairs, posts and small garden work a compact 60 to 120 litre mixer is plenty and easy to move and store. For general building, bricklaying and an extension, a 120 to 160 litre drum is the trade sweet spot that gives a proper barrow load per mix. Only step up to a larger or petrol mixer if you regularly do groundwork, big pours or work away from power.
Then match the build to how hard you will use it. If you mix most days or work with heavy concrete, a belt drive trade mixer like the Belle will outlast a budget unit and hold its value, which makes the higher price easy to justify. If you are a self-builder or a DIY buyer taking on a project or two, a good value electric mixer does the job for far less, as long as you store it dry and treat it sensibly. Check the power you have on site, including whether a 110V transformer is required, settle the drum size and drive, and the right mixer becomes an easy call, and a clean, consistent mix is something you can stand behind on any job you quote.
Cement mixer size is quoted either by total drum volume in litres or by the usable mix it produces, and the two are not the same because a drum only ever works around half full. For light jobs like fence posts, small repairs and bedding slabs, a compact mixer of around 60 to 90 litres is plenty. For general building, bricklaying and a typical extension, a 120 to 160 litre drum is the trade sweet spot, giving a useful barrow load per mix without being too heavy to move. For larger pours and groundwork a bigger drum or a petrol mixer earns its place. Match the drum to your biggest regular job rather than the occasional one, because a mixer that is slightly too big just works less hard, while one that is too small slows the whole job down.
Direct drive mixers connect the motor straight to the drum, which makes them simpler, lighter and cheaper, and they are fine for DIY and lighter trade use. Belt drive mixers use a belt and pulley between the motor and the drum, which cushions the load, protects the motor from stalling on a heavy mix and generally lasts longer under daily trade use, at a higher price and weight. If you are mixing most days or working with heavier mixes, a belt drive unit is the more durable choice. For occasional jobs and lighter mortar work, a good direct drive mixer does the job for less.
An electric cement mixer is quieter, cleaner, needs no fuel and starts at the flick of a switch, which suits most sites with a power supply and almost all DIY use. The catch is you need a socket or a generator within reach. A petrol cement mixer is the choice for groundwork, rural sites, extensions with no nearby power and anywhere running a long lead is impractical, and it tends to drive a larger drum, but it is louder, needs fuel and maintenance and costs more. Most trades run an electric mixer as standard and reach for petrol only when there is no power on site.
Many UK commercial and new-build sites require 110V tools and equipment fed from a transformer for safety, so if you work on those sites a 110V cement mixer or a transformer is often needed to comply with site rules. For home, garden, self-build and general domestic work, a standard 230V mixer that plugs into a normal socket is fine and is what most buyers want. Check the site requirements before you buy, because turning up to a 110V-only site with a 230V mixer means it cannot be used, and a transformer adds cost and weight.
