Have you looked at the Ofcom site?  You may find that the current 
frequencies are actually correct.  Apparently all the transmitters at 
Emley Moor have a 166kHz offset, either + or - depending on the channel.
See 
http://www.ofcom.org.uk/static/reception_advice/dtt_pocket_guide_3_0.pdf 
which lists all the UK transmitters and their offsets.

www.ukfree.tv seems to ignore the offset and just include the base 
channel number.  Generally it doesn't matter since the bandwidth of the 
tuner will be more than sufficient.  Of course, it would be a good idea 
to fix the QAM parameters if they're wrong.
