So presumably you are an employee of BT Group ?
TBH , you probably need to check the specs of the machine , if it’s a sub laptop ( note book ) it may not be particularly advanced, but assuming it is , then it’s possible your line has been mis configured , so set at the wrong line rate , but that doesn’t seem to match up either as the 180Mb is more than the 160Mb profile but less than the 300 or 500Mb profile, and with FTTP if it is connected it’s at the rate set by the administrator.
You maybe should try a speed test with another wired device, or if wireless , like a phone or tablet , a fairly up to date one.
