Star Trek VI also used the same Engineering set. Both that and V, the transporter room with a little redressing. A partitioned off area window between the operator and the pad. Things like that. Engineering as it looked in TNG mostly though. They avoided showing that area with the table-top console, Geordi held briefings around.
That British ad must've cost a bit, even back in 1989/90. Energy companies are probably the only business that would've been able to afford it!
