Does anyone have any experience of the Carlisle SVA centre? Just interested to hear of any experiences and if they are very tight on any particular areas as some other test centres appear to be.

I put a Tiger Cat through Carlisle SVA centre BUT it was 5+ years ago.
At that time they were very reasonable ie. speedo sensor on the front wheel, no means of testing it on their rollers, nothing more said. Youngish tester who was genuinely interested in the car. I passed but of course things may have changed since then. Good luck.
