That sounds like a 'Category 2' ABH from your description, Sweetcarey.
That means that the judge must using a 'starting point' sentence of 26 weeks custody but can actually pass a sentence between a 'lower level' community order and 51 weeks custody. (When a custodial sentence is passed, only half of the nominal sentence is normally served 'inside').
You can read the document that the judge must refer to, here:
