I don’t normally fit hobs or do much gas install work but im installing a gas hob. Am I right in saying it’s just a gas rate of the appliance and check working pressures?
Your not been stupid, most new ones do but lots of old ones don't. As above, in multi dwelling buildings, a hob must be fitted with an ffd. To test it, light the hob, blow the flame out and check the gas switches itself off, and do this for all rings.
