Time related charges (TRC’s) are possible charges we must inform you of before proceeding to log a fault with Openreach. If work of any kind is carried out by an Openreach engineer to rectify your fault, and the fault is found to not be the line, but with your equipment itself, you will be charged a call out fee of £125 inclusive of the first hour and £120 for every hour thereafter dependant on your line type. If the fault is found to be with the line itself, then these charges will not apply. It is therefore vital you fully test and check all onsite equipment thoroughly before proceeding with the logging of your fault.
