Gate hits gas pipe to boiler - fail regs?

[Pin 5]

I thought a gas pipe run had to be 20mm these days. When we had our boiler replaced a few years ago the installers said that the supply pipe from the meter to the boiler had to be changed because the original was 15mm and it had to be 22mm. If that is a reducer then it would be reducing from 22mm to 15mm and, from what the installers told me, 15mm cannot be used as a gas supply pipe. I am no gas installer nor do I know what the regs are. I'm just repeating what the installers told me at the time.

You should stick to not giving advice on gas pipe sizing.
