Guideline users should be aware that the Equal Treatment Bench Book covers important aspects of fair treatment and disparity of outcomes for different groups in the criminal justice system. It provides guidance which sentencers are encouraged to take into account wherever applicable, to ensure that there is fairness for all involved in court proceedings.
Step 1 – Determining the offence category
The court should determine the offence category with reference only to the factors in the table below. In order to determine the category the court should assess culpability and harm.
Culpability
Where there are factors present from more than one category of culpability, the court should weigh those factors in order to decide which category most resembles the offender’s case.
A - High Culpability
- Conduct over a sustained period of time
- Sophisticated and/or planned nature of conduct
- Underlying offence very serious
- Breach of trust or abuse of position or office
B - Medium culpability
- Other cases that fall between categories A and C because:
-
- Factors are present in A and C which balance each other out and/or
- The offender’s culpability falls between the factors described in A and C
C - Lower culpability
- Unplanned and/or limited in scope and duration
- Unsophisticated nature of conduct
- Underlying offence was not serious
- Involved through coercion, intimidation or exploitation or as a result of domestic abuse
- Offender’s responsibility substantially reduced by mental disorder or learning disability
Harm
Where there are factors present from more than one category of harm, the court should weigh those factors in order to decide which category most resembles the offender’s case.
Category 1
- Serious consequences for an innocent party as a result of the offence (for example time spent in custody/arrest)
- Serious distress caused to an innocent party (for example loss of reputation)
- Serious impact on administration of justice
- Substantial delay caused to the course of justice
Category 2
- Suspicion cast upon an innocent party as a result of the offence
- Some distress caused to an innocent party
- Some impact on administration of justice
- Some delay caused to the course of justice
Category 3
- Limited distress caused to an innocent party
- Limited impact on the administration of justice
- Limited delay caused to the course of justice
Step 2 – Starting point and category range
Having determined the category at step one, the court should use the corresponding starting point to reach a sentence within the category range in the table below. The starting point applies to all offenders irrespective of plea or previous convictions.
An adjustment from the starting point, upwards or downwards, may be necessary to reflect particular features of culpability and/or harm (for example, the presence of multiple factors within one category, the presence of factors from more than one category (where not already taken into account at step 1), or where a case falls close to a borderline between categories).

The tables below contain a non-exhaustive list of additional factual elements providing the context of the offence and factors relating to the offender. Identify whether any combination of these, or other relevant factors, should result in a further upward or downward adjustment. In some cases, having considered these factors, it may be appropriate to move outside the identified category range.
Factors increasing seriousness
Statutory aggravating factors:
- having regard to a) the nature of the offence to which the conviction relates and its relevance to the current offence; and b) the time that has elapsed since the conviction
-
Other aggravating factors:
- Offender involves others in the conduct
-
-
-
- Evidence concealed/destroyed
-
Factors reducing seriousness or reflecting personal mitigation
Step 3 – Consider any factors which indicate a reduction for assistance to the prosecution
The court should take into account section 74 of the Sentencing Code (reduction in sentence for assistance to prosecution) and any other rule of law by virtue of which an offender may receive a discounted sentence in consequence of assistance given (or offered) to the prosecutor or investigator.
Step 4 – Reduction for guilty pleas
The court should take account of any potential reduction for a guilty plea in accordance with section 73 of the Sentencing Code and the Reduction in Sentence for a Guilty Plea guideline.
Step 5 – Totality principle
If sentencing an offender for more than one offence, or where the offender is already serving a sentence, consider whether the total sentence is just and proportionate to the overall offending behaviour in accordance with the Totality guideline.
Step 6 – Compensation and ancillary orders
In all cases, the court should consider whether to make compensation and/or other ancillary orders. Where the offence has resulted in personal injury, loss or damage the court must give reasons if it decides not to order compensation (Sentencing Code, s.55).
Step 7 – Reasons
Section 52 of the Sentencing Code imposes a duty to give reasons for, and explain the effect of, the sentence.
Step 8 – Consideration for time spent on bail
The court must consider whether to give credit for time spent on bail in accordance with section 240A of the Criminal Justice Act 2003 and section 325 of the Sentencing Code.
