Can I Use My Hair Straightener (Flat Iron) in United Kingdom?

Q: What plug type does United Kingdom use?

United Kingdom uses Type G sockets at 230V / 50Hz.

Your hair straightener (flat iron) needs a converter and an adapter in United Kingdom.

Why

The device profile's voltage and plug differ from the destination. Do not plug in with only a plug adapter: it cannot change voltage. A converter and a plug adapter that preserves any required grounding may be an option only after checking your actual INPUT label, load type, startup demand, frequency and both manufacturers' instructions. Wattage alone cannot establish compatibility; the wrong setup can damage the device or cause a fire. The cited Conair manuals describe 120V/60Hz and automatically adjusting 120/240V, 50/60Hz models. Do not broaden those ratings to 100–240V. Check your exact model and any converter prohibition; a plug adapter cannot correct an incompatible electrical supply.

United Kingdom runs 230⁠V / 50⁠Hz. Standard 230V at 50Hz. Type G is the large three-rectangular-pin fused plug, used nowhere on the European mainland. A US 120V single-voltage appliance plugged in here without a voltage converter will overheat and can catch fire — a plug adapter alone is NOT enough.

Look for "INPUT 100-240V" on the label. If it shows one voltage only, size any converter from the wattage before buying.

FAQ

Can I use my hair straightener (flat iron) in United Kingdom?

Your hair straightener (flat iron) needs a converter and an adapter in United Kingdom. United Kingdom runs 230⁠V / 50⁠Hz on Type G sockets.

Will a travel adapter let me use my hair straightener (flat iron) in United Kingdom?

No. A travel adapter only changes the plug shape — it does not change voltage. Your hair straightener (flat iron) would still receive 230V.

Do I need a voltage converter for a hair straightener (flat iron) in United Kingdom?

Yes — your device runs on a single voltage that doesn't match United Kingdom's 230V.

What plug type does United Kingdom use?

United Kingdom uses Type G sockets at 230⁠V / 50⁠Hz.
