Finland – Power plug, socket & mains voltage in Finland
Last updated: 23 January 2024
What type of plugs and sockets are used in Finland?
When you are going on a trip to Finland, be sure to pack the appropriate travel plug adapter that fits the local sockets. But what do those electrical outlets look like? In Finland, types C and F are the official standards. Like almost all Continental European countries, Finland has standardized on the German plug and socket system.
- used almost everywhere in Europe & Russia, except for the UK & Ireland
- 220 – 240 V
- socket compatible with plug types C, E & F
- commonly used in Europe, South America & Asia
- not grounded
- 2.5 A, 10 A & 16 A
- almost always 220 – 240 V
- socket compatible with plug type C
What is the mains voltage in Finland?
Just like the rest of Europe, the voltage in Finland is 230 volts and the frequency is 50 Hz.

Finland has standardized on type F sockets and plugs. Type C and type E plugs can also be used thanks to their compatibility with type F sockets.
Power plug & outlet Type C
Typically, type C plug sockets are not allowed to be installed in Finland: these outlets are not earthed and are therefore considered dangerous. Only type F power points are permitted because they are grounded and therefore significantly safer.
The only (and rare) exception to this rule is that an old type C outlet should be replaced by a new one. After all, if you hook up a grounded wall outlet (i.e. type F) on a two-wire circuit, the socket will not be grounded, but people will get the wrong impression that it is actually grounded. No need to say, this would be a potentially dangerous situation.
Nowadays, however, type C receptacles are not frequently installed anymore, since older properties are almost always completely rewired when they are renovated or significantly altered.
