I have been enjoying watching the Jade plant get healthy.
It's not necessary to give your exact location on a public forum, but to say that you are "in the UK" gives only general information as your you geographical location but not enough information for folks to know your climate zone. The more people know about your local climate the better answers they can offer. Even the sunlight coming through a window is different depending on where in the world that window is located.
This link shows that there are several climate zones in the UK.
