At times like this, it's best to look up rule 5 (which is about 2 pages long, and includes both the 500ft and 1500ft rules). So I have.
The 500ft rule is in rule 5(1)(e)
The exceptions to the 500ft rule are in rule 5(2)(d), part (i) of which says "any aircraft while it is landing or taking off in accordance with normal aviation practice".
So the 500ft rule doesn't apply when taking off or landing anywhere - just as Barshaker says.
It is indeed the 1500ft rule (Rule 5(1)(a)) that an aerodrome license gets you off, which is the requirement not to fly less than 1500ft above the highest fixed object within 600m AND able to glide clear (and for permit aircraft, there's an added requirement not to fly over any built up area). But it does still apply when there's no licence, or anywhere outside of the normal circuit. The exceptions are in rule 5(4)(a) and 5(4)(b)
