Calling Thetford from a 01842 number
People answer a local number far more often than an unknown one. Local presence gives a floor a number in the area it's ringing, so a call to Thetford shows a 01842 number rather than one from wherever the business happens to sit. It's an add-on from £49 a month; whether a given code is available depends on what carriers hold at the time, so it's worth asking rather than assuming.
