Note that that section is "Prospective" read the "Status" box at the top of the page. ICBA'd to unpick the several pages of links to amendments that may or may not have been applied to the text of the Act that is shown.
And ICBA'd to follow the trail from:
"(6)The Secretary of State may by regulations exempt from the requirement of a licence under subsection (1) the installation or use of television receivers-
(a)of such descriptions, (b)by such persons, (c)in such circumstances, and (d)for such purposes,
as may be provided for in the regulations."
And the double speak of:
"(7)Regulations under subsection (6) may make any exemption for which such regulations provide subject to compliance with such conditions as may be specified in the regulations."
As is quite common an Act may say one thing but it may well be "amended" by other regulations, schedules etc that the Act refers to. Principly because it's easier to change regulations, schedules etc than the Act itself.
