Best cordless mower deals

Greenworks GWGD24LM33K4

*Average price in the past six months: £190.69. Cheapest price in the past six months: £159.95

• Recommended for small-sized lawns
• Cutting range: 25mm to 65mm
• Weight: 10.2kg (with collector attached)

We like: Quick to assemble

We don't like: Not the best on rough grass

With a cutting width of 33cm, it's a good mower for smaller lawns that are up to 50m². It has five cutting heights, and is powered by a 18V lithium-ion battery.

This technically isn't the best bargain we've seen on it – we've seen the mower itself go for less. However, this deal comes with the battery, which is saving you more money than buying both separately. 

How does it compare to other mowers? Read our Einhell GE-CM 18/33 Li review to find out.

Bosch AdvancedRotak 36V-44-750

*Average price in the past six months: £532.24. Cheapest price in the past six months: £479.99

• Recommended for medium-sized lawns
• Cutting range: 25mm to 80mm
• Weight: 16.6kg (with collector attached)

We like: Quiet

We don't like: Heavy

This electric mower uses a rotary blade (as the name would suggest), but there's a roller behind the blade, which can help give grass a neater finish.

It has a cutting width of 44cm, and its battery should last long enough to mow a medium-sized lawn. You can use the same batteries with other Bosch electric tools.

 Best corded lawn mower deals

Mac Allister MLM1334 Corded Rotary Lawnmower

*Average price in the past six months: £82.33. Cheapest price in the past six months: £75.65

• Recommended for small-sized lawns
• Cutting range: 20mm to 70mm
• Weight: 13.2kg

We like: Lightweight and easy to adjust

We don't like: Awkward grass catcher

This budget-friendly corded mower is more expensive than usual, however – considering it's still under £100 – its value is hard to beat.

To adjust the cutting height, all you need to do is tweak a single lever. It's got six settings ranging from 20mm to 70mm. The cord reaches 10 metres, so if you have a larger garden, you might want extension leads (or to go cordless).

If you've got a small lawn or a smaller budget, this is a great pick.

 Best petrol mower deal

Cobra M41C mower

*Average price in the past six months: £176.18. Cheapest price in the past six months: £125.99

• Recommended for large-sized lawns
• Cutting range: 25mm to 75mm
• Weight: 22kg (with collector)

We like: Easy to use

We don't like: Feels heavy and a bit awkward to handle

We've seen this model cheaper in the last few months, but it's still good value for the money – even if it is pretty basic.

This petrol mower has a cutting width of 41cm, and the collector holds 50 litres of cut grass. There's no mulching function, so you'll need to use the collector.

But how well does it do said basics? Read our Cobra M41C review to find out, or compare prices below:

How to spot a good lawn mower deal

Ceri Thomas, Which? Gardening editor, says:

• A corded mower is usually the cheapest option, but if you'd prefer not to run the risk of cutting the cable while you mow, try a cordless model instead. There are ones that are as powerful as petrol mowers nowadays, and they're much easier to start.
• The cutting width of the mower tells you what size lawn it's suitable for. Smaller cuttings widths (30-34cm) are easy to get into tight spaces on small lawns; while bigger cutting widths (40cm+) make quicker work of getting through large lawns.
• If you don't have much storage space, look for a mower that can have its handles folded so it takes up less space when you're not using it. Some can even be stored vertically to reduce the amount of floor space they take up.

Which lawn mower brand should I buy?
