**Television licences for holiday homes/second homes
If your holiday home/second home contains a television, or equipment capable of receiving a television signal (using an aerial, satellite dish, cable or other means), then this household must also have a television licence. This is the case even if this is not your main residence and you already hold a licence for your main address. Failure to have a television licence where this is required can result in penalties.**

Seems you don't need one in the UK...
**Touring caravans and motorhomes are covered by the TV Licence at the holder's home address and so do not require an additional licence. There are over a million caravans in use in the UK, with over 170,000 motorhomes and over 100,000 residential park homes enjoyed by holidaymakers who appreciate the freedom and flexibility of a caravan-based break**
