My general understanding is that, when taking off, landing, and practicing approaches, (intentional go-arounds) at a licenced airfield, you are exempt from the 500', and the 1,000' rule.
When taking off and landing at an
unlicenced airfield, you are exempt from the 500',
but not the 1,000' rule.
There are some exceptions for training flights.

Ps. I've subsequently discovered that, under SERA, the 1,000' rule no longer applies, so long as you are taking off or landing, regardless of the type of airfield. It does still apply to practice approaches(intentional go arounds) at unlicenced airfields.
