Hi Jonathan I think I'm running into the same thing. I've got a copy of the same two tiles from 2012 (I think), but this suggests that creating mosaics purely from OS TFWs is not simple:
https://www.ordnancesurvey.co.uk/forums/discussion/1001439/1250-000-scale-colour-raster >From my non-expert understanding, is it that the .tfws only give coordinate info, not projection? So, with the full coverage 2009 files I was working from before, I guess perhaps they must have been preprocessed into GeoTIFFs, or resupplied as such, rather than TFWs. tl;dr: my later editions of those tiles are not in the same format, and it will take a little work to get them to work as a mosaic. I'll look at that now.
