If it helps at all Cherie, a friend of my wife got a DD quote that had tripled (lol) but after talking with the company it only actually went up 25%.
Honestly IMO now that we're heading into summer... it's probably better just to get billed for actual usage and prep for spending more in winter.
I'm currently jelly of my sister, who still has an open fire and lives in the middle of nowhere. And she knows local loggers so she can get the wood practically free! (they'll drop off a literal shedload that will last an entire winter for < £100)
Meanwhile we're all paying through the nose for gas
