Zero.
I don't believe you need to go through security again if you connect UK domestic to UK international, at least not from what I observed on my visit last week.
Now if you reverse course, you would have to pass through security when transiting from T-5 international arrivals to T-5 domestic. But again, I saw a whole bank of old-style metal detectors and none of the bad ones.
