Choosing a battery platform is the single biggest cordless-tool decision a UK tradesperson will make. The drill is replaceable in five minutes; the platform locks you in for ten years and several thousand pounds. Get it right and every new tool you buy slots into chargers you already own. Get it wrong and you’ll be running three different chargers in the van and selling barely-used kit on Facebook Marketplace.
This is a UK 2026 guide to the four mainstream cordless platforms (DeWalt XR/FlexVolt, Makita LXT/XGT, Milwaukee M18/M12, Bosch Professional 18V/ProCORE) plus a brief note on Ryobi for the homeowner-leaning end. It’s written for working tradespeople buying their own kit — not a spec-sheet dump. The goal is to help you pick a platform you won’t regret in five years.
If you only have time for one paragraph: pick DeWalt 18V XR if you want the broadest UK retail availability and a cheap second-hand market; pick Makita 18V LXT if you want the largest tool range and a brand most UK trades already trust; pick Milwaukee M18 if you do daily heavy-duty work and want the best drills and impacts on the market; pick Bosch Professional 18V if you already own SDS or measuring kit from Bosch Blue.
Why the battery platform matters more than the tool
A cordless drill costs £100–£250. A cordless impact, a circular saw, a recip, a multi-tool, a router, a sander, a track saw, a 18V leaf blower, a 18V site light, a 18V vacuum and a 18V radio costs another £1,500–£3,000. Every one of those tools is locked to one battery format. If you switch platforms, every battery and charger in your van becomes paperweight.
Practically, that means the platform you choose today defines what tools you can buy cheaply for the next decade. Once you own two or three batteries in a platform, the marginal cost of adding another tool is just the bare unit (typically £80–£250 instead of £150–£400 for a kit). That’s the entire economic logic of cordless platforms — and the entire reason platform choice matters more than the choice of any single tool.
The four mainstream UK platforms in 2026
| Platform | Tool count (UK 2026) | Main retailers | Battery tiers | Strength | Weakness |
| DeWalt 18V XR / 54V FlexVolt | ≈ 350+ tools | Screwfix, Toolstation, B&Q, Amazon UK | Compact 2/4Ah, XR 5/6Ah, FlexVolt 9/12/15Ah | FlexVolt dual-voltage; cheapest 5Ah batteries; biggest UK retail footprint | Top-tier drills/impacts behind Milwaukee FORGE |
| Makita 18V LXT + 40V XGT | LXT ≈ 300+, XGT ≈ 130+ | ITS, Powertoolworld, Toolstop, Amazon UK | LXT 3/5/6/8Ah, XGT 2.5/4/5/8Ah | Largest single tool range (LXT); long-lived cells; UK trade-favoured | Two incompatible platforms; XGT batteries pricey |
| Milwaukee M18 / M12 | M18 ≈ 250+, M12 ≈ 130+ | Screwfix, Toolstation, FFX, Amazon UK | M18 RedLithium 2/5/6/12Ah, M18 FORGE 6/12Ah | Best drills/impacts/recips; FORGE batteries; best app integration | Most expensive starter kits; bare tools rarely on sale |
| Bosch Professional 18V / 12V (ProCORE) | 18V ≈ 250+, 12V ≈ 80+ | Screwfix, Toolstation, FFX, Amazon UK | Standard 4/6Ah, ProCORE 8/12/18Ah | ProCORE batteries punch above their voltage; great SDS and measuring kit | Smaller UK pro adoption than DeWalt/Makita |
DeWalt 18V XR and 54V FlexVolt — the safe default
DeWalt 18V XR is the platform you choose when you want the path of least resistance. It’s at every Screwfix and Toolstation in the country, every B&Q stocks the consumer-grade variants, and the secondary market on eBay and Facebook Marketplace is enormous. 5Ah XR batteries are routinely on offer at £55–£70, which is the cheapest top-tier 18V cell at retail anywhere in the UK.
The FlexVolt side of the platform is the genuinely unique part. A FlexVolt battery is mechanically and electrically a 54V pack that auto-detects when it’s slotted into an 18V XR tool and reconfigures itself as 18V. That means a single FlexVolt 9Ah battery runs your 18V drill, your 18V grinder, your 18V impact, and also runs the 54V cordless mitre saw, 54V table saw and 54V SDS Max breaker. No other UK platform does this. If you ever want a cordless mitre saw or table saw on the same battery as your drill, DeWalt is the platform.
The trade-off is that DeWalt’s top-end drills and impacts (DCD999, DCF961) are now half a step behind Milwaukee’s FORGE-equipped equivalents in raw power and runtime, and slightly behind Makita LXT in vibration smoothness. They’re still excellent — just not the best on the market at headline numbers anymore.
Buy DeWalt XR if: you want the most accessible UK platform, you care about second-hand resale, or you want FlexVolt cordless mitre/table saws on the same battery as your drill.
Makita 18V LXT and 40V XGT — the largest tool range
Makita 18V LXT is the platform with the most tools. Anything that can be made cordless, Makita have made cordless on LXT — including a kettle, a coffee maker, a strimmer, three different stick vacuums and a 18V fan. For working tradespeople, more practically, LXT covers every common power tool with multiple variants at multiple price points, and Makita have publicly committed to long-term LXT development.
LXT batteries are Makita-manufactured cells (most other brands rebrand Panasonic or Samsung cells) which is why Makita batteries routinely last 7–10 years of working use — anecdotally the longest-lived 18V cells in the UK trade. The brushless tools are sweet-running: the DHP484 combi and DTD172 impact are the two most-bought 18V tools on Toolstation and have been for three years.
The trouble is the 40V XGT platform. XGT is a separate, incompatible Makita platform — it doesn’t share batteries with LXT, doesn’t use the same chargers, and the only way to run both is to own two complete battery ecosystems. Makita’s argument is that XGT gives them headroom for the next decade of higher-power tools (SDS Max breakers, 305 mm mitre saws, plunge saws); the user’s argument is that it splits the kit bag and costs double. Most UK tradespeople in 2026 are sticking with LXT and treating XGT as the platform for one or two specialist heavy tools.
Buy Makita LXT if: you want the largest single tool range, you value battery longevity, or you already have Makita kit. Buy XGT only if you specifically need a 40V Makita SDS Max or 305 mm mitre saw and you’re willing to run two platforms.
Milwaukee M18 and M12 — the heavy-duty pick
Milwaukee M18 is the platform that’s eaten a lot of DeWalt’s high-end UK market share since 2020. The M18 FUEL drills and impacts (M18 FPD3, M18 FID3, M18 ONEFHIWF12) are the most powerful cordless tools you can buy on retail in 2026, and the new FORGE battery tier (HD12.0 and HD6.0) delivers genuinely more power than any other UK 18V cell — measurably faster cut speeds, longer runtime, faster recharge.
The M12 side of the platform — separate from M18 — is Milwaukee’s 12V kit for tight-space work. M12 is the platform of choice for plumbers, heating engineers, kitchen fitters and HVAC engineers, because the M12 PEX press, M12 ProPEX expander and M12 SubCompact Band Saw are essentially category-defining tools with no equivalent on DeWalt or Makita 12V. Most M18 users eventually also own a couple of M12 tools and run both platforms.
The downside is cost. M18 starter kits are £50–£100 more than the DeWalt or Makita equivalents, and Milwaukee bare tools are rarely heavily discounted at Screwfix or Toolstation. The Milwaukee resale value on second-hand is, however, better than any of its rivals.
Buy Milwaukee M18 if: your work is daily heavy-duty (commercial sites, formwork, civils, demolition), you want the best raw performance, or you’re a plumber/HVAC engineer who’ll lean on the M12 sub-platform.
Bosch Professional 18V — the underrated platform
Bosch Blue (the Professional range — not the green DIY tools) is the most underrated 18V platform in the UK. The tools are excellent, the SDS rotary hammer range is the best in the trade, and the ProCORE 18V batteries are arguably the most energy-dense 18V cells you can buy on retail — a ProCORE 12Ah delivers similar runtime to a Milwaukee FORGE HD12.0 in like-for-like cuts.
Bosch is the default platform if you already own a Bosch GLM laser distance meter, a Bosch GBH rotary hammer, or a Bosch GLL line laser — the measuring and rotary hammer side of Bosch’s pro range is genuinely class-leading. The drill/impact range is also fine, just not as headline-grabbing as Milwaukee FORGE.
The drawback is UK pro adoption. Bosch Pro has roughly 15–20% of UK trade share against ~30% each for Makita and DeWalt and ~20% for Milwaukee, which means the second-hand market is smaller and you’ll see less Bosch on UK sites. That’s not a quality issue — it’s a market-share issue — but it matters when you’re buying batteries cheaply on eBay or borrowing a battery off a colleague on site.
Buy Bosch Pro if: you already own Bosch SDS or measuring kit, you want the most energy-dense 18V batteries on the market, or you want a slightly cheaper top-tier alternative to Milwaukee.
What about Ryobi, Erbauer and the cheaper platforms?
Ryobi ONE+ is a serious platform for homeowners, occasional DIY-ers and very-light-trade users. The tool count is huge (350+), batteries are cheap, and the brushless second-generation tools are fine. The bare tools are typically 30–40% cheaper than DeWalt/Makita equivalents. The downside is that the chassis durability isn’t comparable to the trade platforms — a Ryobi combi will last a weekend warrior 10 years, but it won’t last a working chippy 18 months.
Erbauer (Screwfix’s own-label) and Titan (Screwfix’s other own-label) sit one step below Ryobi for trade use. They’re fine for occasional jobs but not a platform to commit to.
The honest answer is: if it’s paying your mortgage, buy DeWalt, Makita, Milwaukee or Bosch Professional. If it’s a hobby kit and you spend weekends doing DIY, Ryobi is the best value cordless platform in the UK.
How to decide — a working framework
Step 1: What’s the heaviest tool you’ll need?
If you’ll ever need a cordless mitre saw or cordless table saw on the same battery as your drill, DeWalt FlexVolt is the only platform that does this. If you’ll need cordless SDS Max for breaking, both Makita XGT and Milwaukee M18 FUEL cover it but Milwaukee has more variants. If you only need cordless up to 235 mm circular saw, any of the four platforms will do the job.
Step 2: What does your trade actually use?
Plumbers and HVAC engineers — Milwaukee M12 is a category-defining sub-platform; the M12 PEX press alone is reason to buy in. Carpenters — DeWalt and Makita are roughly tied on circular saws, track saws and routers, with Milwaukee slightly behind on track saws. Electricians — Milwaukee and Makita lead on cable cutters, knockout punches and crimpers; Bosch is strongest on SDS for installation work. Decorators and general builders — DeWalt and Makita 18V cover everything; Milwaukee is overkill.
Step 3: What’s your second-hand budget?
DeWalt has by a wide margin the cheapest second-hand market in the UK, mostly because there’s just more DeWalt in circulation. Makita is next. Milwaukee and Bosch are harder to find cheaply second-hand. If you intend to build out a 8–12 tool platform mostly from eBay and Facebook Marketplace over two or three years, that pushes you toward DeWalt.
Step 4: What do your mates use?
This sounds flippant but it’s a real factor. If everyone on your site is on Makita, being on Milwaukee means you can never borrow a battery. Platform compatibility with your common worksite crews is worth ~10% of the decision in practice.
Common mistakes to avoid
Don’t buy a kit with one 4Ah and a ‘free’ 2Ah
Most kits come with one decent battery and one tiny one. Sell the 2Ah on Facebook Marketplace and buy a second 5Ah or 6Ah — running two real batteries is the difference between a cordless drill being a serious tool and a frustrating one.
Don’t switch platforms after buying three tools
If you find your platform isn’t quite what you wanted after 12 months, your instinct will be to sell up and switch. Don’t. The trade-in losses are brutal — selling three used kits to buy three new ones in a different platform typically costs £400–£800. It’s almost always cheaper to commit to your existing platform for tools that work fine, and only branch out for the one or two tools your current brand genuinely lacks.
Don’t buy cheap third-party batteries for trade use
£25 Chinese cells branded for DeWalt/Makita/Milwaukee fit, charge and run — for a while. They typically use lower-quality cells, no proper BMS, and have killed enough working tools on UK sites that all four major brands now void warranty if a non-OEM battery is detected. For trade use, buy OEM batteries only.
Where to buy in the UK
Screwfix and Toolstation are the safe-default UK retailers for DeWalt, Milwaukee, Bosch Professional and the budget brands. Both stock Makita too but their Makita range is narrower than the specialists. For Makita LXT and XGT specifically, ITS, Powertoolworld, Toolstop and FFX have the deepest UK ranges. Amazon UK is competitive on bare tools across all four platforms but is the worst source for batteries — counterfeits are common at the bottom of the search results.
If you’re buying second-hand, eBay UK is fine for tools but check the battery photos carefully — a faded label, swollen casing or melted contact points means the cell is finished. Facebook Marketplace is the cheapest source for bare tools (especially DeWalt) but the battery market on Facebook is best avoided.
Final verdict
There is no single best platform — there’s a best platform for your trade, your budget and your existing kit. For most UK tradespeople buying into cordless from scratch in 2026, the safe choice is DeWalt 18V XR (with the option to add FlexVolt later) or Makita 18V LXT. Both are mature, both have huge UK retail footprints, both have cheap second-hand markets, and both will still be current and supported in 2030.
For working tradespeople who do daily heavy-duty work and want the best raw performance, Milwaukee M18 is the platform to buy. Bosch Professional 18V is the underrated option that’s especially strong for electricians and anyone already running Bosch SDS or measuring kit. Ryobi ONE+ is the best home/DIY platform but isn’t a serious trade choice.
Whichever you pick, commit to it. The economic logic of cordless platforms only works if you own three or more tools on the same battery — which means the cheapest way to own ten cordless tools is to buy ten tools from the same brand, not to bounce between brands chasing whichever has this week’s £80 deal.
FAQs
Can I run different brand batteries on one tool with an adapter?
Technically yes — third-party adapters exist that fit a Milwaukee battery onto a DeWalt tool or vice versa. In practice, don’t. The adapters break the BMS communication between battery and tool, so the tool can’t read state of charge, can’t manage current draw under load, and will sometimes pull more current than the battery is rated for. All four major brands void warranty if an adapter is detected, and you’ll typically kill a battery or a tool within months. Single-brand only.
Are 18V and ’20V MAX’ the same thing?
Yes. Both are 18V nominal lithium-ion packs. ’20V MAX’ is DeWalt’s US marketing name for what the UK calls 18V XR — the peak voltage of a freshly-charged 5-cell 18V pack measures 20V, hence the name. They’re the same batteries, identical chemistry and identical tools — just rebranded for the US market.
How long should an 18V battery last in trade use?
A Makita 18V LXT cell typically lasts 7–10 years of daily working use before noticeable capacity drop. DeWalt XR and Milwaukee RedLithium are typically 5–7 years. Bosch ProCORE is 6–8 years. Cheap third-party batteries are typically 12–24 months. Charge cycle life matters more than calendar age — a battery used twice a week will outlast a battery used four times a day, regardless of brand.
Should I buy a starter kit or bare tools?
If it’s your first tool on the platform, buy a kit — you need at least one battery and a charger anyway. If it’s your second tool onwards (you already have batteries), always buy bare. Bare tools typically save £80–£150 over the equivalent kit and the second ‘free’ battery in a kit is usually a tiny 2Ah you don’t need.
Is it worth upgrading to FlexVolt or XGT for a single heavy tool?
Only if the heavy tool genuinely needs the extra voltage. For a cordless mitre saw, cordless table saw or cordless SDS Max breaker — yes, the voltage step gives you mains-power performance and is worth the platform stretch. For a 235 mm circ saw or a standard SDS Plus, an 18V tool with a high-capacity battery (Milwaukee FORGE 12.0, ProCORE 12Ah, DeWalt PowerStack) will keep up perfectly well and is cheaper.
