About On-I
A business-only provider of full fibre, Ethernet and leased line connections is how our records describe On-I. A leased line is a private, dedicated link, so a firm that used one should look in its contract paperwork for its current supplier. We found no Companies House record we could tie to the name, and its website address no longer works.
