To clarify, I am not the guarantor nor am I going to be one. But I live currently in a flat that's shared with three other people, one of whom needs a guarantor, and the one she picked is, currently, refusing to sign the paperwork on the grounds that they were worried they'd have to cover the whole flat. I sent a message to them to the effect that while this may be legally true it wasn't going to happen in practice. Not heard back. In the meantime I was hoping to clarify the legal side of things since the best I've found is advice from, say, the Shelter website.
That message I sent on Thursday evening. The prospective guarantor has yet to reply. They really need to soon. I'm worried that it will bounce back on my own living arrangements if it doesn't get sorted out... the lease, which has yet to be signed, "begins" on September 23rd. I don't think we can sustain living in the flat with no lease indefinitely.
