Or if they do, they're doing it later in the day. I cooked a roast earlier, but started at 5pm.
And having looked it up, apparently about 30% of
BRITISH ovens are gas-powered. I'm surprised it's that few, but then anyone with any choice in the matter is going to want a fan oven, even if they combine it with a gas hob.

Octopus did a thing a few years ago where they'd give you all-you-can-eat free electrons for a one hour slot each month. That was based on actual grid prediction, so you got <24 hours notice of when it was going to happen (though it was fairly predictable if you paid attention to the weather forecast), and for astronomical reasons never happened at a sensible
