Clear one here buzz,
Absolutely do it in your hour building as with your night rating if you don't have it.
Incidentially, when I did mine, weather delayed me and missed my arrival at Nottingham, so got East Mids to pick me up on radar and give me a tape that could be checked by CAA if required then just landed at one of my local fields to give me the required landings.
Have fun hour building and make the most of it.
