Hi Stephanie,

# OSGB 1936 / British National Grid
<27700> +proj=tmerc +lat_0=49 +lon_0=-2 +k=0.9996012717 +x_0=400000 
+y_0=-100000 +ellps=airy +datum=OSGB36 +units=m +no_defs  <>

The EPSG code is 27700.  Beware that old versions of proj (prior to 
October 2007) don't have the OSGB36 datum and will plot your data offset 
by up to 100 m.

Later

John
