All that I can think of right now are Sinclair and Amstrad.
I would say most every one on this list has one and possible several
British designed, and possibly UK assembled computers somewhere.
Whilst it does use chips made outside the Raspberry Pi is pretty much UK
designed, using an ARM CPU.
Much of the original layout and circuit was done by one by my old
friends Peter Lomas and it was initially assembled in Wales.
I understand that like the ARM chip it can be licenced by almost any one.
We have a history of helping IBM build computers...
.. their first electronic machine the IBM 701 used Kilburn-Williams
tubes, developed in Manchester and licenced to IBM
.. the later machines used Virtual Memory, developed for the Atlas
computer, again under licence from Manchester University..
.. Speculative Execution probably originates from Heuristic Caching
developed on the MU5 computer....
IBM also ran a major research centre at IBM Hursley, near Winchester,
UK , where CICS support was , and possibly still is based.
Today Manchester still does computer research, so Steve Furber one of
the original designers of the ARM chip has built a million core machine
for Neural Networks

Acorn, ICL, Ferranti, Apricot, Elliot, GEC, Jupiter, Nascom,
Torch, Tadpole, Whitechapel. Oh, and the Raspberry Pi, of course.
Even the Commodore Amiga 1200 was assembled in Scotland.
Well IBM had several plants in the UK. Keyboards and IBM PCs were made
in Scotland. Disk Drives at Havant, Hampshire.

p.s. as for oil, IBM was I think the only company to put its core in Oil
Tanks. Not sure if they ever leaked, but some 70xx machines used this
technique to keep the temperature constant.
