Collection: Voltage Tester Screwdrivers

A voltage tester screwdriver detects whether a wire or terminal is carrying live AC current. When the tip touches a live conductor, a small current flows through the tool's internal resistor, illuminating a neon or LED indicator. It's the fastest way to confirm a circuit is safe to work on. Pair it with tools from our Hand Tools collection for a complete electrical toolkit.

Most standard voltage tester screwdrivers in our range detect AC voltage between 100 V and 250 V, which covers standard European mains (230 V). Dual-range models also detect lower voltages from around 12–50 V, making them useful for automotive and low-voltage wiring. Always check the product specifications before use. Browse the full selection in our Voltage Tester Screwdrivers category.

Traditional neon and LED contact testers are designed for AC mains detection only — they will not reliably detect DC voltage. If you need to test DC circuits (e.g. car batteries, solar panels), you'll need a dedicated multimeter or a purpose-built DC tester. For mains electrical work in homes and offices, a standard voltage tester screwdriver is the right tool. See our Screwdriver Sets for complementary installation tools.

Voltage tester screwdrivers are designed to be safe for general use when handled correctly: touch the tip to the terminal or wire while your finger rests on the rear metal contact. However, you should always follow the manufacturer's instructions, never test a circuit you're unsure about without switching off the breaker first, and ideally have basic electrical knowledge. For confidence in more complex tasks, consult a qualified electrician. Also explore our Pliers range for insulated hand tools.

A contact voltage tester (screwdriver style) requires the tip to physically touch the live wire or terminal to detect voltage. A non-contact tester (pen-style NCV) senses the electromagnetic field around a live wire without direct contact, making it faster for quick checks through cable insulation. Contact testers are generally more precise for confirming specific terminals, while non-contact testers are quicker for scanning cables. Both types are useful on the job. Browse our Wire Cutters for cable preparation tools.

Yes, a voltage tester screwdriver can be used to check whether voltage is present on the input or output terminals of a fuse or circuit breaker, helping you identify a blown fuse or a tripped breaker quickly. Touch the tip to each terminal: if voltage is present on the input but not the output, the protective device has operated. For more about electrical protection components, see our Power & Cables range and the Replacement Cutter Blades section.
