GFCI is mandatory on new installations in the UK, typically 20mA. However there are a lot of older installations without them. However note that the 230V is not served centre-tapped about earth like US range power : We have a 230V 'live' terminal and neutral is earthed at the substation so may be a few volts above earth at the house due to voltage drops in distribution. So it's nominally 230V above earth too, there is no possibility of getting 110V without a transformer.
