It's usually the outside that goes cloudy, not the inside of the lens.  So a good polish of the outside should improve it enough to ensure an MOT pass.

I am fairly sure that mine have gone cloudy on the inside 

Are you sure that's not condensation?

If any moisture has got in from say a crack, the heat from the bulb will make them all steamy, which then condenses on the coldest surface as it cools, which is usually the inside of the lens.

No its definitely not damp
It was the same on the hottest day back in July

Can you post a close up picture?

According to the company who have offered to de-fog my headlamps for £30

"

The cloudy for the headlights becoming dull from the inside are the bulbs
installed in the car, which have a manufacturing defect and release gas
during operation, which settles on the lens on headlight.

"

As if......

Don't think I'll bother !!!

As have mine and it's not condensation. However, the front of the headlights are perfectly clear. The clouding is inside a double "skinned" section an top of the assembly through which no light passes through.

A 2014 Toyota Yaris, if that's relevant?

As is mine I think
It's going to be hurrendously expensive to replace 2017 Suzuki Baleno headlamps - so if it fails the MOT on this, don't know what I will do

Unlikely to fail the MOT but worst case is get replacements off eBay.

Cheap solution - toothpaste, doesn’t always last very long but it will clear them.

You've missed the point - this is between layers on the inside

Correct. In the case of mine it doesn't affect the actual clarity of the lens and has never been mentioned/advised with the MoT test.

I'll attempt a picture.
