Hull-based broadband provider Kcom has been cleared of blocking other companies from entering the market in an Ofcom report.
The Review of the Wholesale Broadband Access to Markets study ruled that the firm was not responsible for a lack of access in the area.
According to the Hull Daily Mail, residents of the area sent 111 letters to the telecoms regulator expressing discontent that Kcom's Karoo service was the only option for broadband.
Ofcom questioned a number of rival telecoms firms - including BT, Cable and Wireless, O2 and Tiscali - and found that none of the companies felt that Kcom was preventing them from entering the market.
"Critics of the company have claimed Kcom blocks rival firms from operating in the city by charging extortionate wholesale prices for the use of its telephone lines," the newspaper suggested.
The Ofcom review comes in response to a number of European Community directives which aim to harmonise levels of service in the broadband sector throughout Europe.
