12V vs 18V Cordless Drill UK: Which Wins?
Standing in the tool aisle, the choice comes down to two numbers on the box: 12V or 18V. We compared the subcompact 12V kits against the full-size 18V models across weight, torque, runtime and price, so you can spend your money on the drill that actually fits the work you do at home.
Key takeaways
- A 12V subcompact drill handles most UK home jobs (flat-pack, shelves, plasterboard) and weighs far less for overhead work.
- An 18V drill is the better pick for masonry, repeated large holes, and if you plan to build a whole cordless system from one battery.
- 12V and 18V use completely separate battery platforms, so pick one voltage and commit, or budget for two chargers.
- If you only want one tool, start on 12V for the lighter feel; if you want a growing kit, start on 18V for shared batteries.
- Our pick for a balanced first buy is a Bosch 18V combi if you need hammer mode, or a Makita 12V CXT if weight matters most.

How the two compare
The voltage rating is not the whole story, but it sets the ceiling. A 12V motor pulls less current, so the tool body stays smaller and lighter, while an 18V motor delivers more torque and runs longer on a single charge when driving tough fasteners. Here is how the camps stack up across the things that actually matter on a UK job.
| Factor | 12V subcompact | 18V full-size |
|---|---|---|
| Typical weight (with battery) | 1.0 to 1.4 kg | 1.6 to 2.2 kg |
| Torque ceiling | Lower, fine for screws and small holes | Higher, better for long screws and hardwood |
| Hammer / masonry mode | Rare on 12V drill drivers | Standard on most combi models |
| Battery sharing | Own 12V platform only | Powers whole cordless system |
| Best for | Light DIY, tight spaces, overhead | Heavy DIY, masonry, growing kit |
| Starting price | Slightly lower for kits | Slightly higher for brushless |
Neither is simply better. The right call depends on the work you do most. If you want the wider field of 18V options we reviewed, see our best cordless drills roundup, and for the smaller end our 12V drill guide covers the subcompact kits in full.
What 12V does best
Subcompact 12V drills have come a long way. Ten years ago a 12V model felt like a toy; now the top ones drive shelf brackets, build flat-pack and drill pilot holes in softwood without breaking a sweat. The real win is the weight. At around a kilo with a compact battery, you can hold one above your head to fit a blind or work inside a kitchen unit without your arm cramping.
Take the Makita DF033DWAE 12V CXT Drill Driver Kit. It uses Makita's slide-style CXT cells, which are slimmer than the older pod batteries, so the drill sits comfortably in a smaller hand. The DeWalt DCD703F1 12V XTREME is part of DeWalt's compact range and pairs a short body with a belt clip, which is handy when you are climbing a ladder. The Bosch GSR 12V-15 FC FlexiClick goes further with a head that rotates and detaches, letting you reach angles a normal drill cannot.

12V CXT ยท 2 x 1.5Ah batteries ยท charger and case included
The Makita 12V kit is a good pick for light home jobs. The slim CXT battery keeps the whole tool balanced, and the two-pack means you are never waiting on a charge mid-shelf. It is a drill driver rather than a combi, so there is no hammer mode, but for wood and plasterboard that is not a problem.
Light and well balanced
Two batteries in the box
Slim CXT cells
No hammer function
Smaller chuck than 18V
Bosch GSR 12V-15 FC FlexiClick Drill Driver
12V ยท FlexiClick interchangeable heads ยท bare or kit
The FlexiClick system is genuinely clever. The chuck locks into four positions and you can swap in a right-angle or offset head, which turns a short 12V body into something that reaches into cabinet corners. For anyone fitting kitchens or working inside carcasses, that flexibility is worth more than raw torque.
Rotating and detachable head
Excellent in tight spaces
Strong Bosch build
Costs more than basic 12V
Heads are an extra step
Where 18V earns its place
Step up to 18V and you get headroom. That extra voltage means more torque for driving long screws into hardwood, and most 18V models are combi drills with a hammer mode for brick and mortar. If your home has solid walls, that hammer function alone can be the deciding factor, because a 12V drill driver will stall on masonry.
The Bosch GSB 18V-55 Combi is the sensible entry into the blue Bosch 18V world: brushless motor, hammer mode, and it shares cells with the rest of the Professional range. The Makita DHP486Z 18V Brushless Combi is the heavier hitter, built for tradesmen who drive hundreds of screws a day, while the DeWalt DCD778S2T 18V XR Brushless Hammer Drill pairs DeWalt's XR line with two batteries so you are rarely stuck.
Bosch Professional GSB 18V-55 Cordless Combi Drill
18V ยท brushless ยท hammer drill function ยท 2 x 2.0Ah
This is the drill we suggest to anyone who wants one tool to cover the house. The brushless motor stretches battery life, the hammer mode handles the odd bit of brick, and because it is on Bosch's 18V system you can later add a cordless angle grinder or a vacuum that runs on the same cells.

Two batteries still sell out fast
Makita DHP486Z 18V LXT Brushless Combi Drill
18V ยท brushless ยท all-metal chuck ยท sold bare
If you know you will lean on it, the Makita brushless combi is the one to beat. The all-metal chuck grips bits firmly, the brushless motor runs cool through long sessions, and it sits on the huge LXT 18V platform. Note it is often sold bare, so budget for a battery and charger unless you already own LXT kit.
Serious torque
Durable all-metal chuck
Biggest battery ecosystem
Usually sold without battery
Heaviest of the group
How to choose for your home
Start with the walls. If you live in a brick or masonry home and expect to put up shelves, curtain poles or TV brackets, you want the hammer mode that 18V combi drills give you. If you are in a timber-frame or plasterboard home doing mostly assembly and light fixing, a 12V drill driver is enough and far kinder on the wrists.
Then think about the future. A cordless drill is rarely the last tool you buy. Once you own an 18V battery you can power angle grinders, saws, lights and inflators from the same cells, which is a real saving over the years. A 12V system is more limited, but the tools are cheaper and lighter, which suits someone who only needs the one drill.
Weight is the quiet factor people forget. An 18V drill with a 4Ah pack can feel like twice the tool after an hour of overhead work. If you have any shoulder or wrist trouble, lean 12V without a second thought.
Frequently asked questions
Final verdict
There is no single winner, only the right fit. For the average UK home that needs one drill for shelves, furniture and the occasional fix, a 12V subcompact is the smarter, lighter and cheaper starting point. If your walls are brick, or you can see yourself building out a whole cordless kit, start on 18V with the Bosch GSB 18V-55 or the Makita brushless combi and let one battery rule them all.
Whichever you choose, buy into a brand you expect to stay with. The drill is the cheap part; the battery ecosystem is where the real value builds up. For more on the smaller end, read our 12V drill guide, and for the full-size field see best cordless drills and the 18V kits roundup.
