Decided to get my timing belt + water pump changed before the NCT so it cost me a lot more than 55 quid.
But I wouldn't say it was part of the cost for my car to pass. I would have changed it even if the next NCT was 5 years away. Same as tyres, brake pads, etc., for me it's all just standard maintenance cost.
Yep drive away. Once you have an appointment your fine. In all fairness to the gaurds though ,they will just tell you to get it done usually. I tell you another thing. If your nct was up and you waited until next year to do it ,you dont get caught for the year you skipped.
