Well Euro 4 petrol came out in 2005. So any petrol after that is exempt. Would be my guess at the comment.

It's badly implemented though. It's only on Euro rating, not actual emissions.

IE a 2000 Honda Insight. 1L 3Cyl Hybrid, is euro 3, as euro 4 didn't exist. Has to pay. A 2005 Civic Type R, is exempt because its euro 4. Yet puts out 3 x the co2, more nox,and more pm.

That Insight is cleaner than a euro 6 diesel! Yet its written off as a more polluting vehicle! There will be plenty more examples, that's just once I've come across.

I've seen it done with celotex type stuff. You can get special toggle things to hold it in place, or trays etc.

Also seen a more DIY approach of mesh netting stapled under joists, and rock wool type roll placed on the netting between joists.
