Looking for some advice. We have three parcels of land all within 10 miles of each other so they have all shared the same CPH number. However we have recently moved house a mile up the road and therefore we no longer have the parcel which is registered as our main holding. Everything is still within 10 miles. Do we now need a new CPH number or can we still use the same one for the parcels we have retained? Hopefully that makes some sort of sense!
