Just to add to the above, I would not advise Now broadband if it is essential for work/working from home purposes .
It's fine for home use - if, and if you understand the service and how a budget service differs and where the corners have been cut to get the price down.
a few reasons why its no good for critical home working/business use:
Customer support - its there but you may have to dig to find it
Basic openreach support, openreach offer the same level of support to all communication providers (ie ISPs) however some ISPs pay a little more for a higher service level agreement
No back up to 3G/4G/5G usually a business function - but present on a few home providers ( that cost more than now) this is where a router has a sim card as well as the usual stuff, if the standard connection goes down then mobile internet takes over unitl the main connection comes back.
Billing - no VAT invoices
Bussiness broadband costs more, but should be more suited to your needs
