Best Torque Screwdrivers for Electrical Safety: 2025 Expert Review
Oli
Owner, OR Electrics & 18th Edition Electrician
A few years ago, most tradespeople relied on 'hand feel' to tighten screws in a fuse board. Today, under the 18th Edition Wiring Regulations (BS 7671), that simply doesn't cut it. Loose connections are one of the leading causes of electrical fires in the UK, creating hotspots that can melt plastic and ignite surrounding materials.
If you are a landlord, homeowner, or budding enthusiast in Leeds looking to understand electrical maintenance, you need to know about torque. Manufacturers of consumer units specify exact torque settings (measured in Newton Metres, or Nm) for every terminal. Too loose, and it arcs; too tight, and you shear the copper wire.
In this review, I'm looking at three torque screwdrivers available on the market. I've selected a budget option for occasional mechanical use, a high-end VDE set for live electrical work, and a certified option for those who need documented accuracy.

Specs vs. The Real World
The Spec: "Usage Context (VDE vs Non-VDE)"
"All torque screwdrivers can be used for electrical terminals."
Absolutely not. For electrical chaos, you must use VDE (insulated) tools if there is any risk of live parts. Standard metal drivers are fine for mechanical assembly (like bikes), but dangerous inside a live consumer unit.
The Spec: "Calibration Longevity"
"Once bought, the accuracy remains perfect forever."
Springs fatigue over time. To maintain accuracy, you should wind the torque setting back to zero (or the lowest setting) when storing the tool. Professional tools need re-calibration every year.
My Top 3 Recommendations
Three options to cover different needs and budgets
BINGCOBBER 1/4” Drive Torque Wrench Screwdriver Set 1-6NM
BINGCOBBER
This is a fantastic entry-level tool for general mechanical tasks. Whilst I wouldn't use it inside a live distribution board due to lack of insulation, it's perfect for assembling flat-pack furniture or bike maintenance where specific torque is needed.
The Good
- Very affordable entry point
- Clear scale makes it easy to read
- Includes a good variety of bits
The Bad
- Not VDE insulated (unsafe for live electrical work)
- Bulky handle can be tricky in tight corners
- Adjustment mechanism feels less refined than premium brands
Installer Tip:
Always pull the collar down to unlock before adjusting the torque, and lock it back after. If you force the adjustment without unlocking, you'll strip the internal mechanism.

Wera
Wera is the gold standard for electricians. This VDE-insulated driver is designed specifically for safety and precision. The 'Safe-Torque' slip-over function makes it impossible to over-tighten, which is crucial for delicate RCBO terminals.
The Good
- VDE Certified for safety up to 1000V
- Impossible to overtighten thanks to slip mechanism
- Extremely fast adjustment of torque values
The Bad
- Premium price point
- Max torque is 2.0Nm (may not be enough for main tails/switch disconnectors which often need 2.5-3.5Nm)
Installer Tip:
Use this specifically for the smaller terminals on MCBs and RCBOs where the manufacturer spec is usually around 1.2Nm to 2.0Nm. For the main incomer, you'll need a higher-range driver.

Sealey
When paperwork matters, this Sealey driver shines. It comes with an individually numbered test certificate matching BS EN ISO 6789:2017 standards. It's a robust middle-ground choice for those who need proven accuracy without the VDE price tag.
The Good
- Comes with individual calibration certificate
- covers the full 1-6Nm range needed for most terminals
- High-quality carbon steel construction
The Bad
- Not VDE insulated
- The aluminium handle can get cold/slippery compared to rubber grips
Installer Tip:
Keep the calibration certificate filed away safely. If you are doing work that requires sign-off or might be inspected, having proof that your tool was calibrated is invaluable.
