Low gas pressure at boiler

I set the output pressure on gas valave (abiout 12 mbar), and while I was at it
checked the supply pressure on the valve as well.
It was about 14-15 mbar. So somewhat low..
I checked the pressure at the meter, it was fine, 21 mb.
21mbar is spot on, but maximum permitted drop in pipework to boiler is 1mbar
