From what I've done I think the joints are ok just not very nice
looking on the whole.
Think the crappy burner might not be helping (Screwfixes cheapest one
with the top/burner and throwaway cannister arrangement). Seems ok but
not sure if it's a good enough flame.

Sounds like you're doing ok.

Try taking the joints apart to see how effectively the solder has covered
the surface, this will give you an idea how effective your preparation
is.

Try not to do what I must have done - carefully prepare one tee, then
pick up another and use it - leaky joint, on disembrangling solder was
found almost nowhere.

I try to get the heat right by using the wire solder I use to top up the
joint, even if there is no need for it.

I give the joint a blast, and try my wire solder on it, if it doesn't rum
I give it a bit more, until it does.

Of course if you just watch the joint you should see the solder ring at
the end, but it is sometimes a bit difficult. Overheating is a problem,
oxidation will occur, prolly the flux will burn, so you're trying to get
it hotenough fairly fast
