BT Openreach is lagging behind on repair targets on unbundled broadband lines, it has been claimed.
According to Peter Black, executive chairman of the Telecommunications Adjudicator, the UK has unbundled 3.195 million broadband lines - a development he conceded is a "milestone".
However, this is tempered by the fact that the rate of repairs to existing lines is still below the agreed targets, Mr Black said.
He told PC Pro: "The underlying failure rate for mainstream repair performance continues at an unacceptably high level (15-25 per cent), substantially short of agreed targets.
"Getting the right person, to the right place at the right time is one of the most difficult things to do and it [Openreach] was starting from a low base.
"There's plans afoot to fix things. BT's shown us those plans and though I would have liked something to have happened by now, we're hoping to see progress [targets met] by the middle of next year."
The adjudicator did however, note an improvement in the Right First Time delivery Figure - a measure of whether customers are getting the service they initially paid for.
This now stands at 94 per cent from August, an improvement of just over two per cent from July.
