Pretty sure it doesn't make much sense today. £100 a year just to have a connection and that is before you even use it for anything.

Heat pumps are far more efficient so even before the electricity tax cut its cheaper to run. Then the savings on having a gas connection too are huge.

And for steak fans who think gas is necessary, charcoal/wood is better. £100 a year would buy a massive gas canister for cooking over, or a massive delivery of firewood.
