Cordless telescopic hedge trimmer: shaft, gap, pack

Updated: October 2026

You are looking at a hedge that has grown past a comfortable handheld reach, and the listings in front of you all shout a different kind of reach. A cordless telescopic hedge trimmer buying guide should settle the shaft, the tooth gap, the battery and the strap before a star rating gets a vote. The [cordless telescopic hedge trimmer comparison](/hub/lawn-and-garden-equipment/cordless-telescopic-hedge-trimmer) is the set of eleven poles kept from amazon.co.uk on 22 October 2026, with prices in pounds. Who each listing is for sits on the [best cordless telescopic hedge trimmer](/hub/lawn-and-garden-equipment/cordless-telescopic-hedge-trimmer/sub/cordless-telescopic-hedge-trimmer-best) page. No hedge was cut for this page. A qualifying purchase can earn a commission at no extra cost to you.

Match the shaft to the hedge, not the biggest reach number

Stand at the hedge and measure the growth you actually have to touch, then compare that with metres of pole. A reach figure that already includes your body is a different number. DIY Garden’s telescopic round-up, updated on 6 October 2026, treats about 2.4 m of shaft as a rule of thumb for a hedge around 2 m, because your arms add height. That is a retail rule of thumb, not a British Standard, and it fails if you cannot hold the head once the shaft is out. Hyundai’s bullets split a 2.6 m extendable pole from up to 3.6 m maximum reach, so the longer number includes you. On the bare Bosch UniversalHedgePole listing, metres of reach are not printed, so that cell stays empty. A chest-high hedge is a different shape, which is pole versus handheld.

Tooth gap and voltage decide the stem, not the slogan

Length does not cut the stem. The tooth opening does, and on domestic cordless poles it is usually about 14–16 mm. That gap is the stem the tooth will admit, not a promise to sever old wood. A 16 mm claim appears on the MZK and the Hyundai rows. Where the gap is missing, as on the BlueMars one-pack, you cannot compare the tooth at all. A 12 V pole is the light-duty end, and reviews stall once the stem is thicker than a trim. A title that says 20 V, or 20 V max, is an 18 V-class label, not a bigger system. Leylandii and most conifers do not regrow from brown wood.

Price the pack, the charger and a second battery

A bigger voltage label does not put a charger in the carton. The Bosch bare UniversalHedgePole is about £99.90 with the battery and charger excluded. The kit of the same family is about £149 with one battery and an AL 1830 CV charger, and the amp-hours are still not stated. If you already own a Power For All 18 V pack, the bare body can be the smaller outlay. The MZK row includes two 4.0 Ah packs and a charger at about £79.99. A single 2.0 Ah pack, as on the Hyundai, means the hedge waits about 60 minutes while that pack charges. The charger still needs a UK 3-pin plug. A 230 V field on a battery listing is a catalogue conflict, not the cutter’s mains voltage.

Weight is the extended head, and a strap only shares it

A pole that feels fine in the box is often top-heavy once the shaft is out. BlueMars’s one-pack row is 3.7 kg on the item line and 3 kg in the bullets. A strap shares the extended head. The MZK bullets do not print a strap, though one buyer only found the pole usable with a harness. Height, overhead lines and brown conifer are on telescopic hedge trimmers for tall hedges.

Common questions

How long a shaft do I need for a hedge about 2 m tall?
About 2.4 m of pole is the rule of thumb DIY Garden uses for a hedge around 2 m, because your arms add height. Shafts in that round-up sat about 2.4–2.9 m. It is a retail guide, not a test of your arms, and it fails if the extended head is already too heavy. Compare metres of pole with the hedge, then check the strap and the mass at full extension on the listing you are about to buy.
Is the reach on the box the length of the pole?
Often it is not. Hyundai prints a 2.6 m pole and a 3.6 m reach, and the longer figure includes you. The bare amazon.co.uk file for the Bosch UniversalHedgePole in this set does not print metres at all. Read the pole length when it is stated, and leave a blank cell blank.
Is 20 V a bigger battery than 18 V?
No. On these poles, 20 V and 20 V max are labels for an 18 V-class pack. A 12 V pole is a lighter, lower-power class. A 36 V pack is a different system, and it is not what a 20 V title is quietly promising. Match the foot you already own before you match the slogan.
What tooth gap maintains a privet, and what stalls on old wood?
A gap around 14–16 mm is the usual domestic figure, and 16 mm is what the MZK and Hyundai rows print. That admits this year’s soft growth. It does not renovate old wood, and reviews on the 12 V rows stall on thick conifer and on established hedges. If the tooth gap is not printed, you cannot assume 16 mm. If the stem will not enter, a higher voltage label will not open it.
Should I buy two batteries or one larger pack?
Two packs let you cut while one charges, which is the point of the MZK’s two 4.0 Ah packs. One 2.0 Ah pack, as on the Hyundai, ties the job to a charge of about an hour. A bare price that excludes the pack is not a complete tool, even when the shelf price looks lower. The Bosch bare tool at about £99.90 is that case unless a Power For All 18 V pack is already yours.
