Hedges have been with us for thousands of years and did you know that the first recorded example of somebody complaining about trimming their hedge dates back to the Neolithic Age, roughly 2,000 to 4,000 years BC. I know, although to be fair the best hedge trimmer back then was probably just a piece of sharpened rock tied to a stick.

Luckily for us, we have access to power tools that our ancestors could only dream of – and that makes the job of bossing obstreperous bushes much easier. But which is the best hedge trimmer for you? Now that spring is well and truly here and the summer months are rapidly approaching you'll soon be in need of one, well, that's if you don't want people to cruelly mock your topiary that is.

As with T3's best cordless lawn mower, best strimmer and best chainsaw buying guides, we've included the best hedge trimmers at a variety of price points here, making sure there is a top-rated model for every budget. And we've also included some buying advice that we think will help you find the best hedge trimmer for your needs, too.

1. Cobra H50-24V

Best cordless hedge trimmer for urban use

Power: 24V
Type: Cordless
Cutting size: 50cm
Telescopic: No
Swappable cutters: No
Weight: 2.6kg including battery
Reasons to buy
+Long twin blade+Efficient hedge trimming+Two speeds for economy
Reasons to avoid
-Fiddly blade cover

•Buy the Cobra H50-24V for £75 from Cobra

If you’re looking for a keenly-priced lightweight cordless hedge trimmer with a decent cutting length (50cm) and excellent run time (up to 50 minutes) then mosey on over here to our new number one choice.

The H50-24V comes with a 24v lithium ion battery and charger, plus a plastic sheath that may just be part of the packaging. Whatever, it’s a bugger to get back on once it’s off so you’re advised to store the trimmer carefully.

This is an excellent trimmer for head-height urban hedges. It’s easy to use and, like Cobra’s grass strimmer, it comes with two speeds: Eco for long-life use and Turbo for thicker branches up to about 1cm.

The Cobra feels great in the hand – the motor housing is really small and unobtrusive – and we really rate the battery-saving two speed option and the long two-sided cutting blade for effortless hedge trimming. It’s not too pricey either.

Best hedge trimmer 2020: Gtech HT 3.0

2. Gtech HT 3.0

The most versatile cordless hedge trimmer

Power: 18V
Type: Cordless
Cutting size: 31.5cm
Telescopic: Yes
Swappable cutters: No
Weight: 2.47kg including battery
Reasons to buy
+Lightweight +Long articulated extension arm +Easy to use 
Reasons to avoid
-Relatively short blade -Slow charging

•Buy the Gtech HT 3.0 from Argos

This extendable cordless hedge edger lets you trim without need for a ladder; it has a reach of 10 feet. For a cordless model, the Gtech HT 3.0 is light-ish at 2.47kgs and well designed. It couldn’t be simpler to assemble as it’s comprised of just four parts: a blade housing, a control handle, a 90cm aluminium extension arm and a small, lightweight 18v Lithium-Ion battery.

It’s a shame you can’t remove the extension arm and use just the bladed end for waist- and eye-level trimming but at least the blade assembly can articulate through 135 degrees so it isn’t too tricky for low-level vertical work. 

That said, when it comes time to tackle the top of your unruly English Yew, this model is in its element, despite it being top heavy. Simply angle the head at 90º and scythe, baby, scythe. Its new uprated blade is now tough enough to cut through branches up to a whopping 6cm in diameter – almost unheard of for a domestic hedge trimmer.

You should get an impressive 60 minutes of running time out of the battery but be prepared to wait up to four hours for it to charge.

The HT 3.0’s blade is shorter than others in this roundup (31.5cm) so it’s not the model to choose if you have 100 metres of hedgerow to manicure, but for everyday urban use it’s a cracker.

Best hedge trimmer 2020: Stihl HSA56

3. Stihl HSA56

Best cordless hedge trimmer for long term reliability

Power: 36V
Type: Cordless
Cutting size: 45cm
Telescopic: No
Swappable cutters: No
Weight: 3.7kg including battery
Reasons to buy
+Great performance+Typical Stihl quality
Reasons to avoid
-Blade is smaller than many-Included battery isn't Stihl's best

• Buy the Stihl HSA56 from World of Power for £173

By their very nature hedges are often found around the edges of gardens and other areas, which means they’re as far away from electrical sockets as you can get. Cordless trimmers solve that problem as well as the safety issues of having a cable hanging out of an electric cutting tool, but as hedges can often be substantial you need to be sure the batteries are up to the job. 

Stihl’s AK10 battery (included) runs for 40 minutes, and the optional AK20 and AK30 deliver 80 and 120 minutes respectively. Stihl’s famous for its professional saws and other tools, and this is a typically safe and solid cutter with relatively low weight and low noise backed by Stihl’s usual build quality.

Best hedge trimmer 2020: Bosch AHS 70-34

4. Bosch AHS 70-34

Best electric hedge trimmer for wider shrubberies

Power: 700W
Type: corded
Cutting size: 70cm
Telescopic: No
Swappable cutters: No
Weight: 3.9kg
Reasons to buy
+Huge blade+Powerful
Reasons to avoid
-It's corded-Probably overkill for most hedges

Trimming really wide hedges can be a real pain, but the longer your cutting blade the less of a pain they become. The Bosch is fairly light at 3.9kg but its cutting blade is an exceptionally long 700mm, with a tooth spacing of 34mm and a sawing function for branches that are too thick to fit between the teeth. 

The 700W motor should make light work of even the toughest hedge, and that long reach means you don’t need to do ladder acrobatics to reach tricky bits. It’s corded rather than cordless - a decent Lithium Ion battery would have added a lot of weight and expense. 

That’s probably for the best, mind: you don’t want to lose power halfway through taming a huge hedge.

Best hedge trimmer 2020: VonHaus 550W Electric Hedge Trimmer

5. VonHaus 550W

Best cheap electric hedge trimmer

Power: 550W
Type: Corded
Cutting size: 61cm
Telescopic: No
Swappable cutters: No
Weight: 3.5kg
Reasons to buy
+It's cheap+Surprisingly long blade
Reasons to avoid
-A bit noisy-Probably won't last forever

At this price you’d expect a trimmer so weak it could barely threaten a hedge, let alone do anything to it. But the VonHaus isn’t bad for the money. There’s a 550W motor and a 61cm cutting blade that oscillates at 1700/m, a 10m cable so you can actually reach things and a fairly lightweight 3.5kg so you won’t get sore arms. 

It’s a little bit clattery, to be honest, but you expect that with budget power tools – and with Amazon selling the trimmer for nearly half price, you can afford to invest in some nice ear muffs if you don’t like the sound. 

The VonHaus is unlikely to last long enough to pass on to your grandkids, but it’s both cheap and cheerful.

Best hedge trimmer 2020: Black & Decker GTC36552PC

6. Black & Decker GTC36552PC

Excellent all-round cordless hedge trimmer

Power: 36V
Type: Cordless
Cutting size: 55cm
Telescopic: No
Swappable cutters: No
Weight: 3.1kg including battery
Reasons to buy
+Heavy duty blades+Good for thicker hedges+Good running time 
Reasons to avoid
-Not especially light -Battery often sold separately

This B&D cordless entry comes equipped with an amply long 55cm dual-action blade that snips through larger hedge branches up to 15mm thick with ease, thanks in part to the 22mm gap between each blade, the powerful 36v lithium battery (swappable with other B&D power gear) and Black & Decker’s E-drive technology.

Despite the lack of a telescopic arm, this is a great option for long periods of eye-level hedge trimming. Its battery provides around 50 minutes of use on a single 90-minute charge, it’s comfortable in the hand and, at 3.1kgs, it isn’t overly heavy for anyone with average sized biceps and deltoids.

This hedge trimmer has garnered a wealth of mostly very favourable reviews; the majority of users are thrilled with their purchase and love the way it tackles thicker hedging without slowing down.

Best hedge trimmer 2020: Bosch ASB 108 LI Shrub Shear Set

7. Bosch ASB 108 LI Shrub Shear Set

Best handheld trimmer

Power: 10.8V
Type: cordless
Cutting size: 10-20cm
Telescopic: No
Swappable cutters: Yes
Weight: 900g
Reasons to buy
+Very small+Very light
Reasons to avoid
-Helpless for larger jobs-Expensive

•Buy the Bosch Shrub Shear Set from Amazon

There are quite a few small handheld hedge trimmers around - Bosch alone makes several different models, and lots of rivals do too - but we think this set offers the best combination of usefulness and flexibility. 

The 10.8V Lithium Ion battery runs for 100 minutes between charges (recharging takes 3.5 hours from flat), there’s a choice of a 10cm grass blade, 12cm shrub blade or 20cm shrub blade, and the tool-free blade switching couldn’t be simpler. 

The real draw here is the weight: at just 900g, you won’t end up with a bad case of Gorilla Arm after using it for protracted pruning. You wouldn’t want to prune a Victorian maze with it, but for relatively titchy topiary it’s ideal.

How to buy the best hedge trimmer

The best hedge trimmer really depends on the hedge you have, and your own personal preferences: good luck trimming hundreds of yards of ancient hedgerow with a tiny handheld. There are hedge trimmers that extend to save you leaning on ladders, trimmers that turn into chainsaws for really thick branches and trimmers with swappable heads for different kinds of work. 

As with most power tools the main choice is corded or cordless: battery-powered devices’ running time is of course limited by their battery, but corded trimmers run the risk of accidentally cutting the power cable. Always put an RCD on the plug your power tool’s connected to. 

It’s worth mentioning that the RSPB would prefer that we didn’t cut some kinds of hedges between March and August. That’s because some birds nest in hedges, so for example in Scotland gardeners have been asked to keep their clippers in the garage until sparrows have fled their nests.

These are our pick of the best hedge trimmers we’d recommend for every kind of job and budget.
