I went to see them and they told me the valve inspection has been moved from the 5th to 6th service 
He said he called Honda about it because he was booking the cost back from Honda as its part of the service plan. "Honda Care" said it no longer needed doing on the 5th.
... but 1 year later it does? I smell a dodge of responsibility. It costs £139 as a separate item.
They likely removed it because the cost of doing it became uneconomical with inflation?
Well it was on my service plan when I brought it so they should honour it - "breach of contract" 
Ill call them and see what they say.
Bear in mind that servicing is not just annual . Its 'annually ,or 12500 miles, whichever comes first'.
Valve clearances dont really need checking until 75000 miles. If you do a high annual mileage and therefore need to service the car every 12500 miles rather than annually it would still not reach the 75000 miles threshold until its 6th service is due, because of its mileage, regardless of its age.
Is it reasonable to expect Honda to include the cost of checking the valves in a 5th year service plan when many owners having servicing annually rather than by mileage will be no where near 75000 miles? If you are sticking to the maximum mileage between services the 5th service should be at a maximum of 62,500 miles.
Or even the 6th year if the car doesnt yet need it based on mileage? Better to make it an option at extra cost depending on actual mileage rather doing every car ,regardless of actual mileage, whether it needs it or not. There is a cost for doing this ,even if its hidden in a fixed servicing price deal.
Some things such as oil and fluids can deteriorate with age and should be serviced or inspected annually even if only a few miles have been covered. But this doesnt apply to valve clearances (assuming oil changes etc havnt been neglected)
Personally I wouldnt worry about getting valve clearances checked until the car has reached 75000 miles, .By which time the car might be so old the cost of having the valves checked might not be justified if its nearing the end of its life anyway on other issues such as rust etc.
