If you operate, manage, or plan to open a licensed premises, you may come across the term Cumulative Impact Zone (CIZ). These zones can have a significant impact on whether a premises licence application is granted — and misunderstanding them is a common cause of refusals.
This guide explains what a CIZ is, why it exists, and what it means. for licence applications.
What Is a Cumulative Impact Zone?
A Cumulative Impact Zone (CIZ) is an area identified by a local licensing authority where the concentration of licensed premises is considered to be causing problems.
These problems typically relate to:
Crime and disorder
Public nuisance
Public safety
Protection of children from harm
When the number or type of licensed premises in an area reaches a certain level, the combined effect — or cumulative impact — may undermine the licensing objectives.
Why Do Local Authorities Create CIZs?
Licensing authorities introduce CIZs when evidence shows that:
The density of licensed premises is contributing to ongoing problems
Standard licensing controls are no longer sufficient.
Additional scrutiny is required to protect the local area.
Evidence may include:
Police crime statistics
Noise complaints
Anti-social behaviour reports
Hospital or ambulance data
Environmental Health Records
CIZs are set out in a council’s Statement of Licensing Policy and MUST be reviewed regularly.
Does a CIZ Mean No New Licences Are Allowed?
No, but it does make applications more challenging.
A CIZ creates a rebuttable presumption of refusal for certain types of applications. This means that unless the applicant can clearly demonstrate that their proposal will not add to the cumulative impact, the application is likely to be refused.
What Types of Applications Are Affected?
CIZ policies usually apply to:
New premises licence applications
Variations that increase:
Hours for alcohol sales
Capacity
The style of operation (e.g. vertical drinking)
Some CIZs also apply to:
Changes in operating model
Late-night alcohol sales
The exact scope depends on the local authority’s policy.
Can You Still Apply for a Licence in a CIZ?
Yes, but the application must be exceptionally well prepared.
To succeed, you may need to demonstrate:
That the premises will not contribute to existing problems
Robust operating conditions
Strong management controls
Clear differentiation from other premises in the area
Common examples that may succeed include:
Restaurants with alcohol ancillary to food
Small, low-impact venues
Premises with reduced hours
Off-licences with strict alcohol controls
Each case is assessed on its own merits.
How Do You Show Your Application Will Not Add to Cumulative Impact?
Successful applications often include:
A detailed operating schedule
Noise management plans
CCTV and security policies
Staff training procedures
Clear alcohol control measures
Engagement with responsible authorities
Importantly, generic assurances are not enough — evidence and detail are critical.
What Happens If an Application Is Refused?
If an application in a CIZ is refused, the applicant may:
Amend and reapply
Appeal the decision
Change the proposed operation.
Early advice can help avoid costly delays and refusals.
Key Points to Remember
A CIZ does not mean an automatic ban on licences.
It does mean higher scrutiny and risk.
Local policy wording is crucial.
Preparation and evidence are essential.
Poorly prepared applications are often refused
Final Thoughts
Cumulative Impact Zones are one of the most misunderstood aspects of licensing law. Many refusals occur not because a business is unsuitable, but because the application fails to properly address concerns about the cumulative impact.
Understanding the local policy — and responding to it correctly — is essential before submitting any application within a CIZ.
