I don't know if anyone here in the USA can help you find some information on your floor lamp. It does show influences from 2 iconic lamps from the UK , the shade is Anglepoise(esque) and the base mechanism looks like a spin off of the classic Bestlite lamps.
Terence Conran/ Habitat made affordable versions of those two iconic lamps but not being familiar with vintage designs from the UK and if Conran and other similar retailers in the UK actually hired designers for these lamps.
