The best electric lawnmowers: from Bosch to Flymo

These best electric lawnmowers shouldn't go amiss this year. Smarten up your garden with ease

The best electric lawnmowers

Looking for the best electric lawnmower to help maintain your garden this summer? Whether you’re trading your old model for a new one or you’re tired of battling with your cylinder mower, an electric lawn mower is the quickest and easiest way to a smarter garden. 

With what seems like an all-year wet season, the UK weather provides prime conditions in which grass can thrive, so lugging the lawn mower out of the garage every weekend (especially through spring and summer) to give the grass a trim is not uncommon. Therefore, investing in a lawn mower that gets the job done quickly, efficiently and well is always a good thing, and electric lawn mowers are certainly one of the top choices, whatever your garden's size.

What is the best electric lawnmower?

We think the best electric lawnmower you can buy is the Bosch Rotak 43 LI Ergoflex Cordless 36. It's cordless, features a huge 50 litre grass box and is great for medium-sized gardens. 

How to buy the best electric lawnmower

What should you be looking out for when investing in an electric lawn mower?

Corded or battery powered?

Electric lawn mowers are available both corded and battery powered. Corded lawn mowers are typically cheaper than battery powered lawn mowers, due to the hindrances of the electric cable; some corded electric lawn mowers may require an extension cable, and you need to make sure that the wire doesn’t get caught up in your prized hydrangea as you make your way round the garden. Due to their convenience, battery powered lawn mowers are more expensive, however, you will need to take into consideration charging time, power and how long the battery lasts in a single use. 


Electric lawnmowers typically have a rotary blade, which makes them the ideal choice for long grass – great if you don’t have the time to be mowing your grass every weekend during the summer. To ensure it doesn’t make a hash out of trimming your grass, you’ll need to consider the power output. The power output for battery powered electric lawn mowers is typically lower than corded lawn mowers. 

Grass box

Aside from that, you may need to take into consideration the capacity of the grass box. Those with larger gardens should, naturally, go for a larger box, however 50L seems to be the generic capacity. If you want to cut out the middleman (the box), our second pick, the Flymo 1200R Lithium-Ion Robotic lawn mower cuts grass into the into minuscule pieces, so it can easily decompose back into the ground.

This Black and Decker lawn mower has plenty of features that make it worthy of our best electric lawn mowers list. It boasts e-drive technology, which gives it a high torque so it shouldn’t stall on particularly tough patches of grass. Perhaps its most attractive feature is its cable management system, which takes away the trouble of keeping the cable out of the way of the blades and motor.

Power: 1300W

Reasons to avoid
- Users say grass can escape the grass box 

While not the biggest lawn mower around, this Flymo is a great lightweight option for small gardens. Gliding across the lawn, it floats on a cushion of air, which means its motor is met with less resistance than if it was on wheels. It also allows for easier manoeuvrability, making it the ideal lawn mower for people who no longer have the strength in their arms or back to operate a regular one. It does only have a cable length of 10 metres, so an extension cable may be required, and there are reports of grass escaping the grass box.
