When draining some coolant I noticed that the radiator tap had a slight drip despite being in the fully off position. Any advice on how best to repair it?

I think if you remove the drain tap you will find that the part that you turn is a tapered plug held in place with a spring and washer and split pin. Dismantle it and you should be able to lap it in with fine emery paper and/or brasso and cure the leak that way.
I know you have only drained off a little coolant for your heater repair but you will have to bite the bullet!!! There is a slight chance that if you operate the tap open and shut a few times it might bed itself in but unlikely.
SNGB don't have a picture on their website but here is a link to a similar tap to show the construction.
