Nope, not correct
I can assure that production continued for many years after 1946 - 1981 I think. Pre war plans for the Perivale facility indicate that considerable expansion was planned, primarily for washing machine production. WW2 changed all that and everything was delayed until 1945.
It is my belief that the government offered Hoover substantial grants and incentives not to expand the Perivale facility (although they were to go on to occupy several other buildings in the general vicinity) but to build a motor plant and canister production in Cambuslang and the washing machine plant in Merthyr to provide employment for returning soldiers - I cannot for the life of me see why else they would have gone to those particular locations.
By 1958 Hoover in UK had facilities at
Perivale - central office & vacuum cleaner
Wembley - Constellation production
Park Royal - bags
(these last two are close to Perivale)
High Wycombe - Irons
Merthyr - Washing machines
Aberdare - Wringers for washing machine
Cambuslang - Motors and "Cylinder" cleaner
I believe production finished in Perivale in 1981 or possibly 1982, although Hoover retained an office these for several more years. Although very much a flagship when designed and built, by the 1970s it was viewed as something of a white elephant, and indeed just this week a work colleague recalled attending a training course there in the 1970s - his description of the facility was not complimentary.
The building was only rescued from demolition by a matter of days and, although the rear is a supermarket, this does not impinge too much on the front view of the building.
