Plastic back boxes

[crystal ball]

I swapped a couple of sockets on new conversion (USBs), the main electrical contractor had used plastic flush back boxes, never seen that before, they looked the genuine article i.e. not surface boxes repurposed, no floating lug though

Are we talking about plasterboard boxes?
ie
Dry-line boxes.
or
The more modern 'studbox', which can be screwed to the studwork before the plasterboarding takes place.

No they were sitting flush in a newly plastered wall, not dry llners or stud box

I've seen such things on 70's jobs, but not on more modern installs, just assumed they didn't catch on

They used to be sold by Woolworths in the 70's.

We have them in a 70s house for both sockets and lights. They go brittle over time and the fixing lugs tend to break when you change the faceplate. Ours do have floating lugs though. They were fitted by the original electrical contractor when the house was built.

They certainly did.

They certainly did go brittle. Helping a friend clear his parents huse for selling we found a woolworths bag with a couple of 'Nettle' switches and plastic back boxes complete with receipt. we couldn't make out the date but the prices 2x 8d & 2x 1/7d. whole thing got dumped as falling apart.

They certainly do go brittle - usually end up fitting surface mounted boxes over them on 'maintenance' type jobs.

The op suggests this may be a newer install - but can't be sure.
