Home cinema - Query on freesat

Can anyone tell me, will a Sky HD box show the FTA and FTV HD
channels on a Freesat-from-Sky card (or its HD equivalent)
without having to pay a Sky subscription?

My elderly F-in-L lives in an area of Sheffield where he can only
get Freeview Lite, so I fixed him up with a s/h Sky box and F-f-S
card. He is very happy with it but tends to watch some of the
less glorious channels - Thomas Cook Travel and things like that.
He really needs a new TV and it would be daft to buy one now not
capable of full HD, but if I get one with internal freesat or use
a Freesat HD box he will loose all of these additional channels
that he likes. It will only complicate things to use a Freesat TV
and retain the old Sky box even assuming the TV has a SCART, so a
Sky HD box that can show FTA/FTV HD without sub would seem to me
to be the answer.

Any thoughts anyone?
