Eurostar trains that run for Eurostar are maintained at North Pole depot
which is in inner north west London. You can see them from the Great
Western Main line from paddington. They use the West London Line to near
Clapham Junction and then the main line into Waterloo.

I suspect you may be referring to the Eurostar sets used by GNER for the
White Rose express services. I think they are maintained at Bounds Green
depot where most of the GNER fleet is maintained. There are smaller
facilities to deal with minor servicing of GNER trains at Newcastle,
Edinburgh and IIRC Leeds.

No - the sets used by GNER for their White Rose service are also maintained
at North Pole. They use the North London line to get to/from King's Cross.
GNER-liveried sets can regularly be seen adjacent to the GW main line.
