as it was a pipe on the heating circuit so all the water would have still drained out of all the radiators through my little hole!

If it's a sealed heating system there will be a safety pressure relief valve on the system, these can be manually operated to rapidly discharge the pressure from the system to outside. Once the pressure has gone from the pipework water should stop coming out of the hole (assuming there is only one hole) as way for air to get in to the system to replace the water which flows out.

If it's not a sealed system then you would need to block the feed and vent pipes at the header tank to stop air from entering the pipework and again it will stop the leak.

In the corner, top of the stairs, gas pipe (I later marked the existence of), luckily I was rather gentle drilling through

gas pipes aren't so bad. no water spurting everywhere, and it's generally no problem to cut the gas off at the meter, then an easy repair. to be sure though, i'd have a gas safe guy do a pressure test.

I was clipping a bit of T&E along a wall below a desk in a room which had previously been a bathroom, one of the clips popped out of the wall and was followed by a jet of water!
It turned out that there was an unused old lead water main in the wall which had just had the open end flattened and plastered in.

Tel has amnesty. Gas safe is not retrospective and in 1897 anyone was allowed to do it... hence Tel is qualified!

Good idea - even if having them means you'll never need them
