Telecoms regulator Ofcom has put forward a plan to solve the long-running dispute over BT's 'overcharging' for business Ethernet services.
The controversy, which initially led to BT being ordered to repay £94.8 million to Sky, TalkTalk, Virgin Media, Vodafone and Verizon, has rumbled on for several years and has been the subject of several legal challenges.
The initial repayment order was contested shortly after being issued in December 2012, with BT telling the Competition Appeal Tribunal (CAT) there was "no evidence" of any wrongdoing.
The CAT upheld Ofcom's decision back in August 2014, after Sky and TalkTalk (jointly), CWW, and Virgin and Verizon (jointly) had also taken legal action.
The row has continued into 2015, but Ofcom has now proposed a final solution to the dispute.
It claims that the correct amount of principal coverage by BT is to be set at £94,620,000, with the corrected figure taking into account the repayment the company is entitled to in respect of the exclusion of excessive construction costs of £203,000.
The regulator added that the corrected principal overcharge to be payable by BT is £22,422,000.
It means the net amount that BT should repay to the disputing parties is £22,219,000, along with interest on the net amount due at a rate of BoE+1 per cent from 29 December 2012.
BT will also be entitled to interest on the overpayment of excessive construction costs.
