The only problem being their minimum labour charge for work done is 1/2 an hour PER JOB so they charged me £16.00 (plus VAT) per bulb, it therefore cost me £45.00 + for two bulbs. They lost a customer that day.
That's sharp practice. It seems to me that the "job" was to change two bulbs. However, their labour rates seem ridiculously low for a main dealer, £32 per hour + VAT = £38.40. My local main dealers charge more than double that. Using your figures, the total bill should have been £42.60, not £45.00+
