Gas only on one burner query

Hi all.  Can anyone advise if there is just a single feed into the gas stove burners ie if some aren't working is it likely that they just need a clean out or are there other potential issues? Thanks in advance Rich

Sounds like blocked jets on the non-working ones.

I think you'll find there will be 1 copper supply pipe which is connected to a manifold in the oven, this then distributes to smaller pipes to the hob, grill & oven.
Sometimes there is a fine mesh filter in the manifold, but as Frank says, check your jets.
