The supply is one question. The room is the other
Most of what gets discussed before a gas appliance goes in is the supply: whether the line and the meter can carry what you want to add. That is a real question and it is a calculation.
There is a second one that gets far less airtime. An appliance burning gas inside a room uses air from that room, and the installation requirements take account of how much air the room has and how it reaches it. That is not about extraction or smell. It is about the appliance having what it needs to burn properly.
It matters here more than in most places for two reasons that compound. The rooms in this housing are small, because kitchens in nineteenth and early twentieth century terraces were never generous. And they have been getting tighter for decades: draught proofing, replacement windows and doors, gaps sealed. Every one of those is a good thing for the household and each one reduces the air a room exchanges.
You would not reliably notice the consequence, which is the argument for assessing rather than judging. An appliance short of air does not stop working, it burns differently, and nobody should be asked to diagnose that by looking at a flame. Where a room cannot support an appliance the answers are ordinary: permanent ventilation, a different appliance, or a different position.
