Denmark uses different plug types, with type K being the official Danish standard, though types C, E, and F are also found in the country.

This guide for UK travellers covers everything from voltage to whether a travel adapter and a voltage converter are needed. We also cover how to stay connected during your trip using an eSIM.

What plug type does Denmark use?

The official Denmark plug type is K, with three round pins and a triangular pattern, but three other plugs are also used there.

Denmark also uses C, E, and F type plugs, with type C and F common across Europe and type E the alternative in France, Belgium, Poland, the Czech Republic, and other countries in Africa.

However, it’s totally different from the UK plug type, which is the G type.

Voltage and frequency in Denmark

Voltage in Denmark is 230 at 50Hz, the same as in Europe, including the UK, but it’s different from other regions, like the US and Canada, where the standard is 110-120V.

Do you need a travel adapter for Denmark?

If you’re travelling from most European countries, you won’t need a travel adapter in Denmark. Even though type K plugs are unique, type C and F sockets fit in these without issues.

However, if you’re travelling from the UK, the US, Canada, Australia, or other regions, you’ll need a travel adapter that fits any of the Danish plugs.

That said, it’s better to buy a universal travel adapter that fits in every Danish plug to avoid surprises.

Do you need a voltage converter for Denmark?

UK and European travellers won’t need a voltage converter for Denmark, as the voltage is the same throughout the continent.

For travellers from the US, Canada, and other 110-120V regions, a voltage converter is needed if using a single-voltage device. If travelling with a dual-voltage device, only a travel adapter is needed.

Travel tip: Always check your electronic devices’ power supply labels to see which voltage they work with and decide whether to buy a voltage converter or a travel adapter.

Where to buy Denmark travel adapters

Since a travel adapter for Denmark is a must-add on your travel list, here are some options for you to buy one:

  1. Before you travel: Buy it on Currys, Amazon, Argos, or your preferred electronics local store. Ideally, get a European travel adapter or a universal adapter to avoid issues with the different plug types. These cost around £5 to £20.
  2. At the airport: Easily found at stores around the Copenhagen Airport, but they are usually three times more expensive than in the UK.
  3. In Denmark: Widely available at convenience stores like 7-Eleven, supermarkets like Rema 1000, and electronic stores like Expert, but better to arrive prepared to keep your electronics working at all times.

Stay connected in Denmark with eSIM

After packing your travel adapter for Denmark, decide what is best for staying connected during your trip to explore Copenhagen, or use Google Translate to translate from Danish to English.

You can rely on a Denmark SIM card from providers like Telenor, Three, or TDC, but that means looking for a store and dealing with SIM swapping and activation. 

Instead, you can travel with an eSIM, and Holafly’s eSIM for Denmark is a great option. Prices start at £3.79 for 1 day, with unlimited data, up to 1 GB of hotspot data, 24/7 customer support, 5G coverage when available, and customizable plans.

You can also try Holafly Plans, a monthly eSIM subscription with prices ranging from $49.90 to $64.90, coverage in over 170 destinations, unlimited hotspot data, and the same benefits as the travel eSIM; ideal to pair with your universal travel adapter.
