Birmingham Clean Air Zone brum breathes.

Approved by Birmingham City Council

Birmingham's Clean Air Zone (CAZ) was introduced to improve air quality. 

Pollution caused by vehicles has a harmful effect on the health of people living, working and studying in the city.

Taxis and private hire vehicles, powered by diesel, must be Euro 6 (VI) emission standard or better to avoid the daily charge to enter the CAZ. 

Drivers can convert their non Euro 6 cabs to our Euro 6 LPG engine with a £5,000 grant.

What is included?

Brand new 2.5L engine, featuring our latest GEN4 system, adapted to operate full time on LPG or petrol.

Including a brand new exhaust system, catalytic converter, radiator, full tank of LPG (80ltrs) and Petrol (15ltrs), testing, wheelchair ramp cover, tyre repair kit, 2year/80k mile warranty, CVRAS & UKLPG registration.

Cost (new GEN4 system): £ tbc

*When using the £5,000 grant scheme (paid post retrofit)

Current grant amount: £5,000

Larger petrol tank option

Subject to availability at time of installation, we have manufactured some larger 40ltr petrol tanks, to give additional peace of mind and added range.

This option is now available for all TX4 Euro 4 models & Euro 5 models. 


The cost of the larger petrol tank is an additional £400+Vat payable at the start of the retrofit installation (subject to availability).

Applying for the grant

The applications for grant funding are done online via the 'Brum Bretahes' website. Click on the link below to complete the application & check the full terms & conditions.  

The grant can be applied for post retrofit, at the taxi operators risk of not being accepted.


A minimum £2,000 deposit is required to book in.

The vehicle must be in a suitable condition for the retrofit e.g. the boot area should be free of rust.


The installation takes place at our workshop in Alcester.

£5,000 is paid on (or before) the cab is dropped off, with the remaining balance due on collection.


When the retrofit has been completed, the cab is ready for collection.


We'll provide a demonstration on how the system operates and how to refuel.  


We submit the evidence of the retrofit to the CAZ team so that the grant can be paid.

The grant can only be paid to the applicant's bank account.
