All of the EU (including the UK and the new candidate countries -- Hungary, Czech republic, Estonia, Latvia, Croatia, Cyprus etc etc and not forgetting Russia and Turkey) works on 220V 50 Hz so your charger will work.
The UK used to have 240 V AC but now conforms to 220V --not that the 20V difference caused any problems anyway.
Any 120-240V charger will work -- these are usually auto sensing so as long as you have the correct mix of sockets and plugs -- no problem.
If you are coming from Canada / USA and are used to a 110V system remember the amperages will be different.
Ohms Law applies as always -- Power in Watts = Voltage X Current in Amperes.
