Clean Diesel does not believe in a 'one system fits all' solution to the Low Emission Zone.

It therefore offers a free optimisation programme to establish what needs to be done in order to pass the Low Emission Zone certification procedure. If a solution is required, Clean Diesel can advise on the number of options available and optimise the technology for individual requirements.

In recognising that many vehicles may only narrowly miss out on compliance without modification, Clean Diesel has developed solutions that reduce emissions for less than £500.

What's more, for some eligible engines, there is a ‘try before you buy’ option for less than £50.

The Optimised programme includes:

  • Free smoke test for eligible engines before VOSA testing
  • Recommendations based on customer needs
  • Purifier e2 solution for eligible engines that do not quite meet the required mark on smoke emission
  • Flexible discounted upgrades to Purifier e3 when required for 40% particulate reduction
  • Further cost effective Purifier e4 options for maximum particulate reduction
