Plus.net provide a great broadband service which we have been using their business packages for 11 years now.
On the rare occasion I have needed to speak to their support department, I have got though to a person who could answer the questions I fielded off the top of their heads!
Plus.net run a referral system, if you do take our recommendation and use them as your broadband provider please can you mention that Esben have referred you. That way we save a bit off our internet bill each month. Then when you recommend them, make sure you get the referral.
