On a built in gas hob they often seem to require a mains supply. Can
they run with just a gas supply?

Is the mains needed just for the ignition or is it also used for
something to do with the flame failure solenoid?

Where's the flame failure solenoid on a hob?

Ours works fine with the power off, it's just for the spark

Built into the hob - I've never taken apart a hob new enough to have a
FFD. But pretty sure they're self-powered and don't require mains.

My brother has a huge 5-burner cooker, where two of the burners are
very large. They have thermocouples poking through, like you see
on pilot lights. You have to press the knobs in for a few seconds
before the burners will stay on, again just like lighting a
permanent pilot flame in a boiler. This also triggers the electric
ignition, but it all works without electricity if you light the
burners with a match. This cooker is probably 10+ years old now.

It was just a general query as someone I know wasn't sure their hob
would keep going in a power cut.

I was guessing it may have something that when the ignition button was
pressed the mains supply may hold the gas supply on for a few seconds
until a thermocouple in the flame or an ionisation detector had a good
signal.

Examination of the installation and operating instructions for a few I
found online made no mention that the electrical connection was
optional if you had access to a match or lighter.

I'm all electric anyway, with a backup camping stove I can connect to
my brazing torch propane bottle.

Slightly confusingly-worded question. "Requires a mains supply". Well,
yes, a mains gas supply, you can't run a mains hob off bottled gas.
Oh, you mean mains *electricity* supply

Not without a jet change, anyway :-)
