I doubt the oil companies would be allowed to operate in the UK the way they do in Africa. They don't really care about safety, they care about profit, no matter what they preach from the pulpit. If the local authorities permit them to do things on the cheap, then they do, and no regrets at all. They don't care if people die, they just care if the deaths cost them money, and deaths in Africa aren't likely to be very expensive. The big oil companies, like Exxon-Mobil, Shell, BP, etc make more in after-tax pure profit than the gross national product of most countries in the world, but that's still not enough, they try to squeeze a few thousand more out of whomever they can. And we cooperate with them to help them do it.
