comment PostGIS: ST_Transform function conversion problem
@CHenderson I'm getting a lot more than 10m+ error. I think that it must be some bug related to the ST_Transform function. My suggestion is to keep the question open for a while to see if anybody else has encountered the same problem, and if not let's close it down. Do you know where I can report the bug?

comment PostGIS: ST_Transform function conversion problem
What I did in the end was to convert the other layer into EPSG:27700 (it's a shape file that I import in PostGIS using the shp2pgsql tool), and to import the GML without transforming the geometry to a different spatial reference system. It then worked as expected, but I would really like to understand what went wrong in the first case.

@CHenderson I double-checked it and the srid is definitely correct.

You might need to add explicit type casts. Any ideas?
