JCB Tools Launches New Petrol Inverter Generator Range

JCB Tools has quietly filled one of the more obvious gaps in its power equipment catalogue. Until now, the brand's generator offering has been built around a few open-frame petrol site machines - the JCB-G3600P and JCB-G8000PE we reviewed earlier this year - aimed squarely at construction sites and trade users who don't mind the noise or the bulk. What it hasn't had is a proper inverter range: the smaller, quieter, suitcase-style generators that campers, caravans owners and homeowners actually shop for.

That's changed. JCB Tools' new inverter generators collection runs from a 2kW entry model right up to an 11kW three-phase unit that wouldn't look out of place on a construction site.

The Six New Models

Every model carries JCB's standard 3-year warranty, produces pure sine wave power safe for laptops and other sensitive electronics, and is quoted at "quiet from 58 dB(A)" on the entry model. All are petrol-only - there's no dual-fuel or battery-hybrid option in this generation, which puts clear water between this range and rivals like Honda's inverter line-up or Champion's LPG-capable models. Full specs for each model are in our JCB Tools inverter generator buying guide, alongside individual reviews of all six machines.

Why This Is a Natural Move for Genpower

JCB Tools products are designed, imported and distributed under licence by Genpower Ltd, the Welsh distributor that took on the worldwide JCB Tools licence in 2023. On paper, launching generators under a construction-machinery brand might look opportunistic. In Genpower's case, it's closer to going back to first principles.

According to the company's own account of its history, Genpower was founded in 2006 by Roland and Lisa Llewellin, and its very first sale - on 26 September 2006 - was a generator, imported under the Evopower brand. The business built out from there: a UK distribution agreement for Hyundai Power Products followed in 2011/12, expanding through 2013/14 into the broader Hyundai catalogue which we follow and reviwed their generator range. By 2022/23 the company had opened a 16,000-pallet distribution centre in Newport, and by 2024/25 reported annual sales of around £48m becoming a leading UK power and garden machinery supplier.

Put simply: before Genpower was a power tool company, it was a generator company. Twenty years of importing, warehousing and supporting petrol generators - Hyundai's range chief among them - is exactly the operational base a new inverter generator line needs: parts availability, servicing know-how, and an existing dealer and warranty network. Combining that generator pedigree with the recognition of the JCB name, which Genpower has held the global rights to since 2023, is a fairly obvious pairing of strengths rather than a brand extension we have been keeping an eye for. 

It also echoes the approach Genpower took with its last major JCB Tools launch. When the company rebuilt the JCB Pro 18V cordless tool platform from scratch, product director Tom Milnthorpe explained the thinking behind entering a crowded market: "The market has strong players, so we wouldn't make this move unless we believed the demand for another serious power tool contender was there," he told The Construction Index at the time. That comment was made about cordless tools rather than generators specifically, but it's a reasonable summary of the same calculated-bet strategy now playing out in the generator aisle: don't launch into a category unless there's a genuine gap and the in-house expertise to fill it.

Where This Leaves Buyers

For UK buyers, the practical effect places JCB Tools as a serious name in the pure sine wave inverter generator market alongside Honda, Hyundai and Champion - and specifically, a JCB-badged alternative for anyone who already trusts the brand from its power tools or site generators but has been buying Honda or Hyundai for camping and caravan power. Because Genpower distributes both the JCB and Hyundai ranges, there's also a slightly unusual situation where the two brands' inverter generators will sit close together on spec sheets and price points - our buying guide flags where that overlap happens and where each brand pulls ahead.
