Walk into any B&Q or Screwfix on a Saturday morning and you'll find an overwhelming row of cordless tools, most of them promising professional-grade performance at weekend-warrior prices. Some deliver. Many don't. After years of running renovation projects across the East Midlands, we've stripped this down to the tools that actually earn their shelf space — and the questions you need to ask before spending.
The Combi Drill: Still the Core Tool
For the majority of domestic renovation work — hanging radiators, fitting kitchen units, assembling flat-pack furniture, driving decking screws — a quality 18V combi drill covers the ground. The combi combines a standard drill, a hammer drill for masonry and a screwdriver with adjustable clutch.
The critical specification to look at isn't maximum torque (which is often a peak figure measured at stall, not at a useful working speed) — it's the number of clutch settings and the smoothness of speed control. Cheap drills jump from 0 to full speed and strip screws into softwood. A decent unit lets you set 20 or more torque levels.
What to look for in a UK combi drill
- 18V platform with at least 4.0Ah battery (gives roughly 40% more runtime than 2.0Ah)
- Minimum 20 clutch settings
- Two-speed gearbox (1st for screwdriving, 2nd for drilling)
- Keyless chuck — saves time, especially when working above head height
- Verified UL/CE marking and UK plug charger included
Battery Platforms: The Ecosystem Trap
Every major brand — Makita, Milwaukee, DeWalt, Bosch Professional, Hikoki — runs a proprietary battery system. This is the most important decision you make when buying your first cordless tool, because once you have three or four tools on one battery platform, switching brands becomes expensive.
For occasional home use, the Bosch Professional 18V system offers solid tools at accessible prices with wide availability. For those running heavier projects or using tools daily, Milwaukee M18 and Makita LXT carry a wider range of specialist attachments and better long-term availability of replacement parts.
"Buying a cheap drill today locks you into cheap batteries tomorrow. Choose the platform, then choose the tools."
The Jigsaw: Underrated for Home Renovation
Most homeowners think of jigsaws as sheet-cutting tools. In practice, a decent jigsaw does the work of three other tools in renovation: cutting worktop cutouts for sinks, trimming door bottoms after fitting new flooring, cutting laminate skirting boards to angle. The pendulum action setting makes a significant difference on thick timber — use 0 for clean cuts in tile backer board, and maximum pendulum for ripping through structural timber quickly.
Multi-tools: Where They Actually Earn Their Place
Oscillating multi-tools were often dismissed as gimmicks. They've matured considerably. The undercutting blade alone justifies ownership for anyone fitting new flooring — it cuts the bottom of door frames to allow new flooring to slide underneath cleanly, a task that's genuinely difficult to do any other way. Grout removal, caulk cutting, flush-cutting in tight spaces: these are things no other tool handles as cleanly.
Power Tool Comparison: Common UK Tasks
| Task | Primary Tool | Alternative |
|---|---|---|
| Fixing to brick/block walls | SDS Hammer Drill | Combi drill (slow masonry bit) |
| Cutting worktop hole for sink | Jigsaw | Router with guide |
| Cutting skirting to angle | Mitre saw | Jigsaw + protractor |
| Removing old tiles | SDS with chisel | Multi-tool (slower) |
| Undercutting door frames | Multi-tool | Hand saw (awkward) |
| Drilling through joists for pipe | 18V combi (flat bit) | Hole saw on combi drill |
What You Don't Need to Buy
Skip the angle grinder for general renovation work — hire one for the two occasions you need it rather than buying one that sits unused. Same logic applies to rotary sanders for floors: a drum floor sander hired from HSS for a weekend costs a fraction of ownership and does the job better than a hand-held orbital. The Health and Safety Executive publishes guidance on safe tool use for DIY and trade applications that's worth bookmarking if you're moving beyond basic tasks.
Maintaining Your Tools
Cordless tool batteries degrade fastest when stored at very high or very low charge. For lithium-ion packs left unused more than a fortnight, store at approximately 40–60% charge in a cool, dry location. Blow dust out of ventilation slots after any heavy use — accumulated dust in the motor housing is the leading cause of premature failure in power tools used on renovation sites.
