Best Cordless Lawn Mower UK: Reviews of Battery Powered Mowers

It has to be said, Bosch makes some pretty good stuff and the Rotak 430 Li ErgoFlex is another such tool.

This particular model comes with two batteries, each one giving you 30-40 minutes worth of mowing time. The batteries take a couple of hours each to charge but will be 80% of the way there in an hour.

Talking of the batteries, you’ll need to turn them on before the mower will work. I just plugged it in and tried to start the mower and nothing happened. It took some digging through the instruction manual to find out why.

Considering the size of this mower, it’s incredibly light at just 13.9kg so it’s really easy to move around. This is also helped by the super comfy Ergo Flex handles.

It has a 43cm deck size and a 50-litre grass collection box. As such so you can mow a fairly large area before stopping to empty the bag.

The height adjustable cutting deck offers 6 cutting heights so you can mow as low as 20mm and as high as 70mm.

The grass combs worked well too (the red fins). They’re designed to guide the grass into the blade when mowing along edges where the grass meets a wall or raised decking. This reduces the need to finish off with a strimmer.

The Bosck Rotak 430 Li ErgoFlex also has a rear roller between the back wheels. This means you can mow right to the edge of your lawn without the risk of scalping it. It also means you’ll be left with a nice striped finish.

Overall, this cordless lawnmower easy to use and manoeuvre, it cuts well and the two batteries make it a great choice for large lawns.

The Murray IQ18WM37 is my top pick as one of the best cordless lawn mowers for most people.

It comes with the right balance of price, size, features and build quality.

The mower feels very well built and is powered by a Briggs & Stratton battery system which features two 18v Lithium-Ion batteries to deliver 32 minutes of use. It also comes with a twin charger for parallel charging which fully charges both batteries in 55 minutes.

You can also use the batteries in other power tools in the Murray range. When you’re not cutting the grass, you can use the batteries in their grass strimmer, hedge cutter and leaf blower.

It features a brushless motor which reduces wear and expands the operating life of the machine. All while keeping it super quiet when in use.

The deck size is 37cm and cutting heights range from 25mm – 75mm via the very smooth, single large lever.

The grass collector has plenty of capacity too at 40 litres. For longer grass, you can remove the collector completely and discharge the cuttings from the rear.

When I tested it, I cut several hundred square metres of fairly long grass in half an hour and it still only half way empty.

It’s one of the comfiest to use thanks to the soft-grip handles and the fact that it only weighs 12.5kg makes it very easy to manoeuvre. The blade is excellent and left a very acceptable finish. Although a rear roller would have been nice.

And to top it all off, the mower itself comes with a 5-year warranty and the batteries come with a 3-year warranty.

Overall, for the mower, battery and charger system, this cordless model offers excellent value for money.

The Flymo Mighty-Mo 300Li is Flymo’s first cordless lawn mower and is a massive seller in the UK.

It’s the smallest and cheapest model on my list.

The words ‘small’ and ‘cheap’ are probably the reasons it’s such a hit.

With a weight of less than 10kg and a 30cm cutting width, manoeuvring it around even the smallest lawns is a doddle.

You get 30 minutes of battery life from a 2-hour charge.

Five cutting heights range between 25mm – 65mm and the grass collection box has a capacity of 30-litres This should be more than enough for small urban lawns.

It has to be said, the finish it leaves is rather good. Much better than I was expecting if I’m being honest.

I have to say, it does feel a bit cheap. But that’s because it is.

Also, although the battery works perfectly well when you mow the lawn regularly, it’s quick to drain when cutting longer grass.

Overall though, it’s a good mower for small lawns and when you don’t want to spend a lot. It’s cheap, incredibly light and very easy to manoeuvre and provides good value for money.

Just don’t expect too much from it.

I must admit, I’d never heard of Aerotek until I came across this particular model during my research.

It comes very highly reviewed amongst users so I thought I give it a try and I’m glad I did! Like the Murray, the Aerotek cordless lawnmower is part of a bigger range of power tools which use one battery.

A one hour charge gives you up to 35 minutes of mowing which makes it a good mower for medium-sized lawns.

It’s also very easy to operate. Lift up the smoky grey flap on the top of the mower, plug the battery in and off you go.

At 13.4kg the Aerotek is light and easy to move around but it still feels robust and well made.

The deck size is a decent 40cm and the six cutting heights range from 25mm – 75mm.  This is combined with a 50-litre capacity grass collection box. When you’d rather keep the nutrients from the grass cuttings in the lawn, you can turn it into a good mulching mower by attaching the mulching plug.

I have to say, it leaves a very good finish too.

Thanks to its brushless motor, this lawn mower is not only quiet, but there’s also no maintenance to do apart from keeping it clean at the blade sharp.

When you’re not using it, the handles collapse in a kind of scissoring motion so you can store it away nice and small.

Like I said at the beginning of this review, I doubt you’d think of Aerotek when considering a new lawn mower.

That said, this is a cracking little machine and I was surprised at how well it performed.

You can’t really talk about battery power without including EGO Power. They make some of the best cordless mowers in the industry. The EGO Power LM2130E-SP is a beast!

It’s exceptionally well built and the power equals that of many petrol mowers of its size. All without the fuel, noise and servicing costs.

That said, you can buy it without the battery and charger if you already have other tools and batteries in the EGO range.

It’s packed with features too.

The motor is brushless which increases the operating life of the machine. It also means is pretty quiet.

The 52cm cutting deck size combined with the 28mm-90mm cutting heights means it can mow long grass with ease. Plus, the massive 70-litre grass collector means it can tackler larger lawn with fewer trips to the compost heap. For more manicured lawns, you’re able to mulch the grass cuttings and recycle their nutrients back into the turf.

It’s an excellent self-propelled cordless mower with adjustable speed so you can set it to your preferred walking speed.

The cutting speed is variable and increases and decreased automatically depending on the length of grass. This ensures the delivery of enough power as and when it’s needed.

It even has LED headlights that lights up your lawn so can work longer into the day. And when you’re finished with it, it’s very easy to store away.

The Ego Power + is an incredible cordless rotary mower for large lawns. If you’re after the best that money can buy, this is it. If you don’t have the batteries, then it’s worth buying the kit with them as you save a good amount of money.

I have to admit, I wasn’t a fan of the first G-Tech Falcon.

It took five hours to charge the battery, the handles flexed and moved far too much and there were a few other issues.

Still, it didn’t stop it becoming one of the fastest-selling cordless mowers in history.

Now though, they have released their Falcon 2.0 and I’m happy to say it is much, much better than the original.

They’ve introduced a 48v Lithium Ion batter and reduced the charge time to just an hour to give you a battery life of 40 minutes. In addition, they’ve increased the grass collector size to 50 litres and completely re-designed the handle bar assembly so now they’re much sturdier. It also folds down for easy storage.

And they’ve made it lighter at just 13.5kg.

As a result, it’s very easy to use and manoeuvre and the standard of cut is excellent.

G-Tech hasn’t only improved their existing features, they’ve added some impressive innovations.

Firstly, they’ve fitted the Falcon 2.0 with a carbon steel blade. It’s actually half a blade fitted with a counterbalance. This reduces vibration and battery consumption while still cutting with the efficiency of a standard rotary blade.

Another great feature is the variable motor speed which changes depending on the length of the grass. Not only does this make the battery life much longer, but it’s also brilliant for keeping noise down to a minimum.

It does come at a cost though because it’s not cheap at around £500. That said, the price hasn’t put people, it’s still an incredibly popular model.

If you’re the proud owner of a formal or ornamental lawn, then only the best cylinder mower will do.

In which case, let me introduce you to the Allett Liberty 43.

It has a 410-watt motor, powered by a 10A 40V Lithium-Ion battery. A 100-minute charge will give you around 40 minutes of use.

It cuts beautifully thanks to the 6 bladed cutting cylinder which gives you 79 cuts per meter.

To make sure you cut every single blade of grass, there is a fixed rake behind the front roller. This stands the grass up right before it’s cut. That said, if you want an even better cut, you can upgrade to a 10 bladed cutting cylinder.

Mowing heights range from 6mm – 32mm. Adjusting the height is easy using a single dial.

It weighs in at 38.5kg so it’s by far the heaviest machine on this list. That said, it is the weight that contributes to the intensity of the striping effect. It’s also self-propelled so pushing it around the garden is no problem at all.

And the Liberty 43 isn’t just a lawn mower. You can change the blade cylinder for other cartridges (for an additional cost) and take care of all aspects of caring for an ornamental lawn.

These attachments include an; aerator, lawn brush, dethatcher, scarifier and verticutter.

The Allett isn’t for everyone though.

If your lawn is bumpy, uneven for full of meadow grass, it’ll be useless. The blades will jam and you’ll risk wrecking it.

However, if you have well-cared-for ornamental lawns that you’re serious about maintaining, the Allett Liberty 43 is probably the best cordless cylinder mower there is.
