Hi and welcome to the forum. When you say your home gets cold how cold, do you have your day a nd night temps for your home, the enclosure you have listed is as mentioned too small, and with yhe exo terra tanks probably mure expensive than a zoo med repti breeze which can be easily adapted to help with both temperatures and humidity, depending apon your budget there also are muji panthers and jungle jims( these are more expensive but worth the money, but a repti breeze is good enough) vivariums, but best to do a run down of things you want along with things you need as everything adds up quickly, , I also live in the uk and had no issues with the repti breeze enclosure,
