Standing around on a cold site in a normal jacket only gets you so far. A battery-heated jacket running off the same 12V or 18V platform as your tools adds genuine, adjustable warmth without the bulk of extra base layers — and if you’re already invested in a battery platform, it’s an easy add to the kit bag rather than another charger to carry.

How Do Heated Jackets Work?
A heated jacket runs thin carbon-fibre or wire heating panels off the same battery you’d put in a drill or impact driver, usually with 2–3 heat settings controlled by a button on the chest. Runtime depends heavily on battery size and heat setting — expect anywhere from 2.5 hours on high to 8+ hours on low with a larger battery.
1. Milwaukee M12 ToughShell — Best Overall for Site Work
The ToughShell earns its name — the outer shell is genuinely more weatherproof and abrasion-resistant than most heated jackets, which matters when it’s also your everyday work jacket rather than something you only wear on the coldest days. Three heat zones spread warmth evenly rather than just heating your chest, and it runs off the same M12 batteries already in most UK trade vans.
2. DeWalt DCJ069 — Best for DeWalt Users
If your van is already full of yellow and black, the DCJ069 is the obvious pick — it shares batteries with the rest of the DeWalt 12V/20V range, so there’s no extra charger or battery format to carry. It heats up fast and holds a comfortable, even warmth across the chest and back.
3. Makita DCJ205Z — Best for Makita Users
Makita’s LXT platform is the largest cordless ecosystem on a lot of UK sites, and the DCJ205Z slots straight into it. Sold bare (no battery included) at a noticeably lower price than most rivals, it’s a sensible buy for anyone who already has spare 18V batteries sitting in a case.
4. Milwaukee M12 Axis — Best Heated Layering Piece
The Axis is built to be worn under a normal work coat rather than as the outer layer itself, which makes it a genuinely useful mid-layer on the coldest days without needing to swap out your usual jacket. It’s lighter and less bulky than the full ToughShell, trading some weatherproofing for flexibility.

5. Bosch GHJ 12+18V — Best Compact Battery Option
Bosch’s Professional heated jacket is compatible with both the 12V and 18V ranges, so it works whichever battery size you happen to have charged. The included battery and USB charging adapter mean it’s ready to wear straight out of the box, which not every heated jacket on this list can say.
What to Consider Before Buying
Battery Platform First, Jacket Second
The single biggest factor should be which cordless platform you already own — a heated jacket that shares batteries with your drills and saws costs nothing extra to run, while one on a different platform means carrying and charging a battery type you’d otherwise never touch.
Jacket vs Vest vs Hoodie
A full jacket gives the most warmth and works as your everyday outer layer; a heated vest or layering piece like the M12 Axis is better worn under an existing coat on the coldest days without replacing your usual workwear.
Sizing — Go Up If Layering
Most heated jackets are cut for a base layer or thin midlayer underneath — if you plan to wear thicker layers under it in deep winter, size up rather than buying true-to-size.
Washing
Always remove the battery and controller before washing, and check the manufacturer’s specific care instructions — the heating panels themselves are generally machine-washable but the electronics are not.
Is a Heated Jacket Worth It?
If you’re regularly outdoors in UK winter conditions and already own batteries for the matching platform, yes — the difference in comfort on a cold static job (waiting on deliveries, first fix in an unheated shell) is significant enough that most tradespeople who try one don’t go back.
The Verdict
Go Milwaukee ToughShell if you want the best all-round jacket regardless of platform, pick whichever brand matches your existing batteries if cost matters more than absolute best-in-test, and consider the M12 Axis as a lighter layering option rather than a full jacket replacement.
