The Office of Communications (Ofcom) has published its final determination in resolution of a dispute brought by Digital Region Limited (DRL) and Thales UK Limited (Thales) against BT Telecommunications plc (BT) in relation to charges for three of BT’s wholesale connection and rental sub-loop unbundling (SLU) products.

Ofcom concluded that certain costs incorporated into BT’s SLU charges were not costs related to provision of the products and as such BT had not complied with its regulatory obligations. BT must now adjust these charges as of the date of the determination so as to reflect only those costs which can reasonably be derived from the costs of provision, and is to reimburse DRL and Thales for any overpayments made.
