If you’re stood at the Screwfix counter holding a DeWalt combi drill in one hand and a Milwaukee one in the other, wondering which one you should actually commit to — you’re not alone. These two are the dominant platforms for UK tradespeople, and the decision you make today will shape what you buy for the next five to ten years. Switch platforms halfway through and you’re either running two sets of batteries or starting over again, and neither of those options is fun.
We’ve put this head-to-head comparison together to cut through the marketing noise. Both brands make genuinely excellent tools. Neither is objectively ‘best’. But one of them is usually better suited to your specific trade, budget and workflow. Here’s how to decide.
The Quick Verdict
Pick DeWalt if: you want a balanced platform with strong availability across UK retailers, you’re price-sensitive, you work across multiple trades, or you’ve already got a 18V XR kit and want to grow it.
Pick Milwaukee if: you want the current king of high-end cordless, you work in heavy-duty applications (breaking, impact driving, demolition), you want the widest modern tool range, or budget is less of a concern than outright capability.
That’s the short version. If you’ve got two minutes more, the full comparison below will tell you exactly why.
Brand Overviews
DeWalt — The Trade Default
DeWalt is the platform most UK tradespeople have used, are using, or will use. Owned by Stanley Black & Decker and manufactured in the US, Europe and Mexico, DeWalt’s 18V XR platform has been the backbone of UK cordless trade tooling for over a decade. More recently, their XR FLEXVOLT system has extended the same battery platform to high-power tools (circular saws, SDS drills, chop saws) using 54V-effective batteries that still run all 18V XR tools.
You’ll find DeWalt in every Screwfix, Toolstation, B&Q and most builder’s merchants. Spares, batteries and chargers are easy to source and often on promotion. The brand has a reputation for being tough, reliable and rarely surprising — it does what you expect it to, for a long time.
Milwaukee — The Pro Specialist
Milwaukee is owned by Techtronic Industries (TTI) and has, in the last 10 years, repositioned itself as the premium pro cordless brand. Their M18 platform is the core 18V system, with M12 for compact sub-compact tools (plumbers and electricians love M12 for tight-space work). Milwaukee has invested heavily in brushless motors, smart technology (ONE-KEY tool tracking and customisation), and expanding into niches other brands don’t touch — press tools for plumbers, specialist cable pulling tools, wall chasers, heavy-duty breakers.
Milwaukee is more expensive than DeWalt in most categories. Availability is good in the UK but not quite as ubiquitous — you’ll find core ranges in Screwfix and Toolstation, but some specialist lines are mainly through dedicated Milwaukee distributors or Amazon UK.
Battery Platforms Compared
| Factor | DeWalt | Milwaukee |
| Core voltage | 18V XR + 54V FLEXVOLT (shared platform) | M18 + M12 (two separate platforms) |
| Battery tech | Li-ion, brushless motor standard | REDLITHIUM Li-ion, REDLINK PLUS electronics |
| Battery sizes | 2.0Ah – 12.0Ah (XR and FLEXVOLT) | 2.0Ah – 12.0Ah M18 + M18 HIGH OUTPUT |
| Run-time at top end | Excellent with FLEXVOLT 9Ah/12Ah packs | Excellent with HIGH OUTPUT HD12.0 packs |
| Compact sub-platform | DeWalt 12V MAX (limited UK range) | M12 (very strong range, UK-focused) |
| Battery warranty (UK) | 3 years standard | 3 years standard |
| Price per battery (UK) | Usually £20-40 cheaper per pack at same Ah | Higher, but HO packs deliver more power |
Tool Range and Availability
Both platforms cover all the everyday cordless tools a tradesperson needs — combi drills, impact drivers, circular saws, SDS drills, reciprocating saws, angle grinders, jigsaws, nailers, torches, vacuums. Where the difference becomes clearer is in the extremes.
DeWalt’s Strengths
- FLEXVOLT tools are genuinely excellent for heavy work — the 54V table saws, mitre saws and SDS max drills are proper site tools that rival corded for most jobs.
- Wider range of budget-conscious tool options. DeWalt often has two or three tools at different price points in the same category.
- Exceptional availability in UK builder’s merchants — if you need a spare battery on a Sunday morning, it’s usually a DeWalt you’ll find first.
Milwaukee’s Strengths
- M12 sub-compact platform has no real equal in the UK market for tight-space electrical and plumbing work. M12 ratchets, M12 installation drills, M12 inspection cameras.
- Unmatched range of specialist pro tools — M18 FORCE LOGIC press tools, M18 wall chasers, M18 MX FUEL equipment for heavy breaking and demolition.
- ONE-KEY tool management — Bluetooth inventory tracking, anti-theft lockout, tool customisation for specific applications. Useful for fleet managers and site managers with large kit registers.
Durability and Build Quality
Both brands are built for trade use and both will take serious abuse. The differences are in the details.
DeWalt tools have a reputation for rugged, ‘can take a drop off a ladder’ construction. The XR 18V drill and impact driver combo is arguably the most-tested cordless combo in the UK — they run, and run, and run. Repairs tend to be straightforward and the after-sales network is extensive.
Milwaukee has been closing the gap on overall build toughness in the last 5 years, and in some specific areas (brushless motor durability, sealed electronics) it now leads. REDLINK PLUS overload protection is a genuine differentiator — tools cut out cleanly before burning out, and many mid-range Milwaukee tools outlast DeWalt equivalents in heavy-use testing. However, the more specialist a Milwaukee tool gets, the more expensive the repair if something does go wrong.
Price and Value
On a like-for-like entry to mid-level combo (drill + impact driver + 2 batteries + charger + bag), DeWalt is typically £20-80 cheaper than Milwaukee for a comparable spec. That gap widens at the budget end, narrows at the pro end, and sometimes flips at the very top end where Milwaukee’s M18 FUEL tools are genuinely class-leading.
Battery prices are where the long-term cost difference shows up. A 4.0Ah Milwaukee pack will usually sit £15-25 above a DeWalt XR 4.0Ah, and that adds up fast once you’re running four or five batteries. Over a typical 5-year period of running a full cordless kit, the DeWalt platform will usually be £300-600 cheaper in total cost of ownership for equivalent tool coverage.
That said — if you’re a high-billing trade where tool performance directly translates to job speed, the Milwaukee premium can pay for itself on individual jobs. Press tools, wall chasers and heavy impacts in particular deliver job-time savings that justify the cost.

Which Should You Buy? By Trade
Electricians
Milwaukee edges this for most UK electricians. The M12 sub-compact range is simply unmatched — the M12 FUEL right-angle drill, M12 installation driver, M12 inspection camera and M12 stubby impact ratchet are tools that save time every single day on first-fix and second-fix. Pair that with M18 for heavy drilling and you’ve got a comprehensive electrical kit. DeWalt is still strong and cheaper, but doesn’t match M12 for compact work.
Plumbers and heating engineers
Milwaukee wins again, and more decisively — M12 compact ratchets and impact drivers, M18 FORCE LOGIC press tools, M18 transfer pumps, and the M12 M-SPECTOR inspection camera form a plumbing kit that’s genuinely ahead of DeWalt. If you do regular press-fit work, Milwaukee is the obvious choice.
Carpenters and joiners
DeWalt is usually the better fit. FLEXVOLT circular saws, table saws and mitre saws are outstanding. The XR cordless nailers are well-regarded, and price-per-tool is lower than Milwaukee’s equivalents. Unless you’ve already invested in Milwaukee, there’s no compelling reason to pay the premium for cordless carpentry tools.
General builders and groundworkers
DeWalt tends to win on value across a broad tool set. FLEXVOLT heavy tools plus XR everyday tools covers most of what a general builder needs. Milwaukee MX FUEL is superior for serious breaking and demolition but overkill for most general building — and a significant investment.
Fabricators and metalworkers
Milwaukee has the edge for cordless metalwork — the M18 FUEL angle grinders (particularly the 125mm and 230mm FUEL models) are exceptional, and the M18 metal-cutting circular saws and bandsaws are ahead of DeWalt’s offerings. Worth the premium if metal is your daily.
Mobile maintenance and multi-trade
Either platform works. DeWalt gives you cheaper kit and wider high street availability. Milwaukee gives you better specialist tools when you need them. Honestly, for multi-trade work, whichever you’ve already started on is the right answer — don’t switch platforms without a strong reason.
Final Verdict
Both DeWalt and Milwaukee make excellent cordless tools. There’s no bad choice here — but there is a choice that’s better suited to your specific trade.
For most UK tradespeople not already committed to a platform, we’d recommend DeWalt for price-sensitive, trade-generalist and carpentry-focused work. The XR/FLEXVOLT ecosystem is mature, well-stocked, reasonably priced and covers 95% of what most trades need.
We’d recommend Milwaukee for electricians, plumbers, fabricators and anyone who values the specialist end of the cordless range. The M12 compact platform alone is enough to swing electricians and plumbers, and the M18 FUEL pro range genuinely justifies its premium for heavy and specialist applications.
Whatever you pick, commit to it properly. Running two platforms doubles your battery investment, halves your standardisation, and generally works out as a false economy. Pick one, build out from the basics, and resist the temptation to grab the other brand when it’s on offer. A deep DeWalt kit is almost always more useful than a shallow mix of DeWalt and Milwaukee — and vice versa.
Frequently Asked Questions
Can DeWalt batteries fit Milwaukee tools (or vice versa)?
No. The battery platforms are proprietary and physically different connectors. There are third-party adapters floating around online — we don’t recommend them. They compromise the warranty on both tools and batteries, and in our testing the power delivery is never as reliable as the genuine platform.
Is Milwaukee really worth the extra money over DeWalt?
For specialist pro work (M12 compact, M18 FUEL heavy, M18 FORCE LOGIC press tools), yes. For everyday cordless work where you just need a reliable drill and impact driver, the difference is real but marginal — DeWalt offers 85-90% of the performance for 70-80% of the price.
Which platform has better UK aftermarket support?
DeWalt. Parts, batteries and chargers are more widely stocked, and repair centres are more common on the high street. Milwaukee aftermarket is improving fast but still not as ubiquitous.
Should I buy Makita instead of either?
Makita LXT is the third major option and has a huge range. We’d generally put it between DeWalt and Milwaukee in terms of build quality and price. Strong platform but smaller UK distribution than DeWalt in our experience. Worth a look if you want a third option — but stick to one platform.
Can I mix M12 and M18 tools?
You can own both, but the batteries don’t cross over. Many UK pros run M18 as their main platform with a few M12 tools for tight-space work. This is a legitimate ‘two platform’ setup and works well for electricians and plumbers.
