UPDATE: Independent Gas Safe engineer came. He said the valve just needed adjusting. He cleaned the burner and all good except an NCS given that the kitchen cabinet it sits in is slightly too small for the manufacturer's ventilation dimensions. I've learned by lesson. Don't use PP and get an...

I'm still trying to get a feel from the point of view of the gas safety inspection. For a system boiler that is non-modulating would you ID/AR/NCS if the gas rate/inlet pressure is say 20% below the nominal rating from the factory?

Pimlico Plumbers. Yes, I'm getting an independent for a 2nd opinion.

He said the gas meter was fine but said the gas hob needed replacing because of no flame safety device.

Thanks, for the responses. https://shieldheating.co.uk/wp-content/uploads/2025/09/tb-141-gas-rating-of-domestic-boilers-acceptabletolerances.pdf I note from TB141 it says the following. But, even if it's out of tolerance, would this be an AR or a NCS?

I would have though that if there was a problem with the flue gas then the report would state: "incomplete combustion" etc. rather than "gas rate failed".

No readings were provided on the paperwork. I was told that its gas rate was too low and therefore it was dangerous. I did query but told it would need replacing. It's a Potterton Suprima. Could this be fixed by either adjusting the gas pressure adjuster, and or cleaning the burner?

Hello, A boiler was given a ID because "gas rate failed" and "pressure at appliance failed". However, the guy who performed the tests signed the Responsible Person/Gas User box and not the Gas Safe Engineer's box, and vise versa, so I'm not even sure the paperwork is valid. In any case...
