The thing is that Britain has an independent oil and gas sector though. We're not reliant on imports, so yeah, the blame can be levelled at the Tories for this one.

You're not reliant on imports, but unless you outlaw the export of energy you're still subject to the global price of energy. If they can export it cheap enough, energy producers would rather sell it to mainland Europe or around the world rather than sell it for less domestically.

Most of the oil and gas from the North sea is exported, at the same time the Tories suggest more fracking as if extra oil and gas wouldn't also be sold.

That oil and gas sector is still reliant on international gas prices, since it's a global market. I'm not sure if it's even possible for a single country to commandeer its fossil fuel production for own use without sparking a few international conflicts.

Britain is at much higher risk because unlike Germany and several other countries on the continent it has virtually no gas storage capacity. Here in Germany we have at least two full months of reserves. Despite Britain's size it has only 1% of the storage capacity that the continent has, even the Dutch storage capacity is nine times higher. One of the reasons? Britain closed one of its largest domestic storage facilities in 2017 for budget reasons. (750 million over ten years)

Obviously the war plays an important role but Tory economic philosophy is well at work here as well, just like in any other public sector.

The reason for this though is that we do have a marine gas terminal infrastructure... unlike Germany.

The UK also has large percentage of Europe's LNG ports. The "storage" is in the form of LNG tankers constantly docking and unloading here.
