Where possible, and certianly any items of value, I always use the Post Office Special Delivery Guaranteed by 1pm Service. This service is handled quite differently than 'normal' post

I have found this service first class. It is not the cheapest service but that matters not when you get first class service, fully tracked, signed for, good £'s cover for loss and a very quick delivery. If I cannot use that service then I always use another Post Office/Parcelforce service

I have NEVER had a problem with any of the Post Office/Parcelforce services and will continue to use them

I have had experience of Yodel and would certainly not recommend them, a real nightmare
