The question has been asked many, many times regarding the legality of using a television when camping.  

Tekkie Anne has emailed the TV Licensing Authority and has received this email in reply.  

The relevant passage has been highlighted in red.

If your second home is a static caravan or mobile home and television receiving equipment is not used at both addresses simultaneously, and you do not let out your second home and provide television equipment, you will not need a separate TV Licence.  Some chalets can also be considered as static caravans if they are moveable.

If your second home is a static caravan or mobile home and you use

television receiving equipment at both addresses, or you let out your second home, you will need a separate TV Licence.

Touring caravans used for touring from place to place and motor

vehicles do not need a separate TV Licence providing a licence is held at your main address.

Where landlords let holiday homes and provide television receiving equipment for holidaymaker's use, they should ensure that the property is correctly licensed.

However, it is the landlord's responsibility to ensure that the televisions they supply in rental accommodation (including holiday

accommodation) are licensed.  It is an offence to watch television without the correct TV Licence.

People staying in rented accommodation using the landlord's television, should check with the landlord to see if a TV Licence has been purchased.

If there is no licence, the user will need to purchase a licence themselves.

If someone owns more than one unit of holiday accommodation on the same site and provides television receiving equipment, they may be able to apply for a special TV Licence which is cheaper than buying one licence for each unit.

You can obtain details of this licence by phoning 0844 500 5820.
