Enabling Technology for Clean Air Zone (CAZ)

Decision Maker: Chief Executive

Decision status: Recommendations Approved

Is Key decision?: Yes

Is subject to call in?: No


Bristol City Council has been directed by Government to implement a Charging CAZ D.
The Council's proposal consists of deploying both fixed ANPR cameras and mobile systems to enforce the Clean Air Zone. The contract also includes a full back-office management system and interfaces to other applications / agencies.
A recent tender was carried out for both CAZ and Bus Lane Enforcement (BLE) devices so that the Council has one contract/one supplier. The contract was awarded prior to JAQUs decision, and as per the tender was initially for just the BLE element. A Tender Report for this was signed off by the Executive Director Growth and Regeneration on 22.06.21.
Now that JAQU have formally signed off the Council’s full business case for a Charging CAZ D, the Council needs to ‘enable’ the CAZ D element of the contract.


Approval to spend £872k over 5 years to enable the ‘CAZ D’ element of the existing contract for the provision of ‘approved devices for unattended enforcement’ to start with immediate effect.

Alternative options considered:

1.To wait for formal approval of this Key Decision by Cabinet in December 2021.
The anticipated programme delivery time of c8-9 months is likely to push Go Live until Autumn 22 if work does not begin until late December 2021. The project is also looking to mitigate risks in the supply chain for the ANPR devices which may further delay implementation. This may have a negative impact on the Council’s ability to achieve compliance with the Air Quality standard by 2023.
