Disconnecting Gas Stove: DIY or Professional Service? Guide on Safety Measures & Permissions

Hello
In a few days I am changing the furniture in the kitchen and I have to get everything out of it. I have a question about disconnecting the gas stove. Can you do it yourself by turning off the gas supply with a valve in the pipe, or does it have to be done by some professional? I have heard that you need to have permission to do so, and the assembly and disassembly of the stove can be done by someone who has such permissions.

do it yourself, but check if you have a working valve!
connect the new cooker to a flexible hose with a quick coupler

Skryn is right only that such a guy will delete you, and not necessarily do better than you.

Before disconnecting the hob, check that the valve in front of the hob wants to close at all - if so, then good.

Close the valve and unplug the stove, after disconnecting the stove, plug the valve and, if you can remove the valve lever, it protects against accidental opening of the valve and gas outflow.
This is how it looks, remember carefully and ventilate the room well.

Good luck!

Thanks. I will disconnect the stove by myself and let someone with these rights take care of the connection. In the store, they told me that if I connect myself, I will lose the guarantees for the kitchen.
