Virgin is the main option.
Did look at a 4G home broadband but theres no one currently providing in the area where I live (Mobile companies withstanding but costs are ridiculous and I wont use EE and no Vodafone signal where I’am)
Found a company called VISPA that seemed OK for the above but don’t cover my area currently.
Failing that its looking at the cheaper options for line rental plus BB.
Then you have to factor in reliability and quality.
I went down this route recently and I ended up with a company based in Sheffield called XILO.
Currently paying £21 a month for line rental inc BB with 50GB data plan(plus unlimited data outside of peak times).
Looked at PlusNet,Tesco,Talktalk etc but all seem to have very mixed/poor reviews.
