- Which is best, the HT20 or HT05 Plus version
- What attachments are available and best to use
- The key features of this hedge trimmer
- The downsides of the HT20
- Whether it’s right for you
Let’s dive straight in…
2019 Update: GTech continue to sell this hedge trimmer due to its performance, reliability and how many customers love it. They have added the extension pole to the optional extras and regularly run deals for other items such as the ST20 grass trimmer at discounted rates.
Who are GTech?
They’re a British company with a good record of creating cordless, electric garden tools and vacuum cleaners.
They are known as a competitor to Dyson, and recently became a household name by sponsoring Channel 4’s Gogglebox. GTech (Grey Technologies) was created by Nick Grey, a British inventor.
Top Tip: GTech offer a 100% money back guarantee if you buy direct from them.
Meaning no risk to you if you don’t like their product. I recommend going direct, rather than through a re-seller.
However…Be sure to keep all packaging. And it costs £10 to make a return for shipping costs.
Good to know…
I previously reviewed the GTech HT04 hedge trimmer. The HT20 is the new & improved model, and the HT04 is no longer available to buy, so forget about that one…
Highlights of the HT20 include:
- Lightweight, only 2.25kg
- Precision blades cut 15mm stems
Easy to Use
- Adjustable head angle (135º) for hedge tops
- Interchangeable branch cutter head (sold separately)
- Reassuring British 2 year warranty
- 30 day money back guarantee
- Powerful 18v, Lithium-ion battery
- 45 min run time from a 4 hour charge
Why Buy Cordless from GTech?
G-Tech are really taking the cordless electric range of power tools to the next level. Launched in the Spring of 2016, this cordless hedge trimmer adds to an impressive line up of garden power tools.
2019 Update: This GTech HT20 model is still one of the best hedge trimmers on the market. If you’re looking for a new one for 2019 you can rest assured that it lasts.
It’s reassuring that not many changes have had to be made to the product because it lasts and does the job. Customers love it, overall.
It’s a cordless tool so it’s powered by battery. The lithium-ion battery lasts for 45 minutes from a 4 hour charge. Spare batteries are available which are interchangeable with the GTech ST20 grass trimmer. Bonus!
It’s incredibly easy to use due to its lightweight (2.25kg) build, ergonomic design and adjustable head angle. You can use it to trim high hedge tops, bushes and everything in-between. Ideal if you don’t like step ladders.
The angle of the head adjusts through a range of 135º meaning it’ll cut straight hedge tops when you’re standing on the ground.
The blade length is 31.5cm (315mm). Replacement parts are available direct from GTech should you need them.
The standard precision blades do a fantastic job of cutting through stems of up to 15mm thick, so it’s suitable for most hedges. However, if you want to cut something a little thicker you can use the optional branch cutter (sold separately). Simply detach the head and attach the branch cutter and away you go.
The branch cutter head cuts up to 6cm (60mm) in diameter branches.
Extension Pole (optional extra)
The long reach of the HT20 can be made even longer with this extension pole. It’s an optional extra, so will cost you around £40, but if you have long hedges or really don’t like step ladders this could be a good choice.
This will allow you to reach an extra 50cm higher.
The Best Time to Buy…
If you’re looking for a good deal, a good time to buy is Spring. By summer, companies know that you need a hedge trimmer so the prices are usually higher.
GTech often have Spring deals to get their sales up early and you get a saving. Win-win!
I’d recommend checking out the GTech site to see if they have any offers on. If they do, and you feel this cordless hedge trimmer is for you, it’s worth purchasing now before the prices go back to normal.
Having said that, the price doesn’t fluctuate too much. Only be around £10 because it’s already a great value item.
What people are saying…
In general users love the lightweight ease of use that this HT20 hedge trimmer offers. No more step ladders for those high hedges.
The ability to angle the head makes trimming the tops very easy. But don’t take my word for it, here is what one user had to say:

So, What’s the Downside?
Some users have said that it is awkward to use and perhaps a little heavy. It’s a personal thing. The fact is, it only weighs 2.25kg so is very light for a hedge trimming tool.
For a hedge trimmer that costs £129, it cannot be compared to one which costs £400.
If you need to cut through thicker branches, the optional branch cutter head attachment is an excellent addition.
2019 Update: Over 4,500 people have reviewed this hedge trimmer on the GTech site and it continues to receive rave reviews. 4.7 out of 5 stars is pretty impressive.
- Lightweight, new and improved design
- No petrol, lasts for up to 45 mins from a 4 hour charge
- Can handle stems up to 15mm
- Long reach and adjustable for hedge tops
- Interchangeable heads for branch cutting
- Not designed for large branches
Not Sure if it’s Right for you?
Whether you decide to buy the GTech hedge cutter or not is entirely up to you. I am here only to give you a little guidance.
Note: If you have very large hedgerows to tackle this might not be your best option. Check out the specifications section on the GTech site and really think if it’s suitable for you.
It is designed for small to medium sized hedgerows, not for jobs which take hours to do.
The bottom line…
If you want an efficient, cordless electric hedge trimmer to cut a range of hedges in your garden for up to 45 mins at a time, this GTech HT20 model is for you.
If you need it for use on a more industrial scale with overgrown bushes that have thick branches and stems, you’re better off with a sturdier machine like a petrol powered one.
