National grid, improvements discounted thread?

[Andehh]

I'm sitting on an accepted quote of £1900 to swap out single phase to three phase next month.

 

However I am sure I stumbled across a thread on here a few weeks ago suggesting grid improvements would be free of charge as people move to bugger renewable and home charging. 

 

I can't find the thread though, and check if I'm eligible and could potentially save some money. 

 

Am I going mad, or does anyone know if a thread like this?.. Thanks

Ask @pocster he was looking into it.

We know what the new rules are in theory, but I have yet to hear from anyone who has succeeded in getting upgrade charges removed or reduced.
