As answered by people managing Gumtree and Cert Decoder.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:

Your only luck could be to check shared flats on gumtree.com or spareroom.com - a few years ago I got a room in a shared flat when a tenant had a secondment out of the country for 3 months. But that was just luck. Source: over 3 years ago
The other popular website to look at is gumtree.com, or at least used to be. Source: about 4 years ago
