Sorry I didn't realise that Zen networks was referring to Zen the ISP or I would have replied to your question.
Zen is an ISP, an excellent one at that. The monthly fee is £23.82 + VAT. Total £27.99 but if it's for your work then you should be able to claim back the VAT or at least your employer can for you.
There is no monthly contract and they are a superb ISP to be with, rated as one of the most reliable and fastest connection speeds available.
I'm with them myself and have not had a single problem in the nine months or so that I have been using them. click here for the home page and click here for further information. Also click here for the ADSL guide compare chart and you will see they come first month after month for reliability/speed and service. If you place an order with them they will have you up and running in 3-5 days.
I think they are still in business but don't know as I have never needed to get in touch with them ;o)
