Free PME upgrades. A common practice now??

[NDG Elecs]

Enquired with NEDL about two possible TT upgrades to PME. I found the screenshot below on their website. It used to cost around 160 quid for the intake to be changed but now it's apparently free.
Are other DNOs doing this? Has there been some legislative change?

I haven't used it it, but UKPN say it might be free ...

I suspect hell will freeze over before WPD will do it for free.

(Edited to include info from their current website, and their price list).

Well I didn't know that was NPG's policy. I knew they started changing cast iron heads for free at the start of this year, but that's very useful news. I've arranged probably 15 or so head changes for customers this year.

SSE did my last place for free.

SSE has always been free as far as I know.
