This is the Support forum which is for answering general questions about the TripAdvisor website.

It will be extremely expensive since the rental company has to get the car back to Norway - there is very little demand for left hand drive rental cars in the UK
I noticed that you inadvertently posted your question on our TripAdvisor Support forum, so I have moved the topic on our behalf to the Oslo forum. I hope you find the information you need to plan your upcoming travels.

That's great, thanks!
