Relevant Sentencing Guidelines

The Sentencing Council's 'Assault Definitive Guideline' applies to all offenders aged 18 and over sentenced on or after 13 June 2011, regardless of date of offence. Section 20 offences are covered at pages 8 - 10 therein.

STEP 1 - Determine the offence category.

  • Category 1: Greater harm (serious injury must normally be present) and higher culpability
  • Category 2: Greater harm (serious injury must normally be present) and lower culpability; or lesser harm and higher culpability
  • Category 3: Lesser harm and lower culpability

The court should determine culpability and harm caused, or intended, by reference only to the factors listed in full below at STEP 1 HARM AND CULPABILITY FACTORS (as demonstrated by the presence of one or more). These factors comprise the principal factual elements of the offence and should determine the category.

STEP 2 - Use starting point to reach a sentence within the category range. It applies irrespective of plea or previous convictions. A case of particular gravity could merit upward adjustment from the starting point before further adjustment for aggravating or mitigating features, listed in full below at STEP 2 SERIOUSNESS FACTORS.

  • Category 1 
    Starting Point (Applicable to all offenders):
    3 years' custody
    Category Range (Applicable to all offenders): 2 years 6 months - 4 years custody
  • Category 2 
    Starting Point (Applicable to all offenders):
    1 years 6 months custody 
    Category Range (Applicable to all offenders): 1 - 3 years custody
  • Category 3 
    Starting Point (Applicable to all offenders):
    High level community order 
    Category Range (Applicable to all offenders): Low level community order - 51 weeks' custody

STEP 3 - Any other factors which indicate a reduction, such as assistance to the prosecution

STEP 4 - Reduction for guilty pleas

STEP 5 -  Dangerousness - specified violent offence

STEP 6 - Totality principle

STEP 7 - Compensation and ancillary orders

STEP 8 - Reasons

STEP 9 - Consider remand time
