one minor (if pedantic...) point - licence is the noun, and license is the verb (apart from in US english where for some stupid reason they're swapped around...)
Also, if you have a separate tenancy agreement, if you only have a tv in the communal area (eg your living room) as far as I know you only need one licence. You need a separate licence for each bedroom (or whatever room(s) are covered by the separate tenancy agreement) that contains a tv in addition to the communal one.
