For resale a series of stamps in the book is a good idea but it won't really matter whether they're by Honda or not. An annual oil change would be wise, but air filter, cabin filter, plugs, general greasing and tweaking can be done on a milage basis.
The type of service you get with a combined MoT is probably sufficient annually, with a full service when you hit 20k. If you have a CVT then you should have it's oil changed every two years or 25k miles, you might stretch the time period a little as your milage is low.
