Is this a good Mulch?

Hi,
Last Sept I had a very large Sycamore tree cut down in my garden (it was end of life and had to chop before it fell), the tree surgeon left a huge pile of chippings that went through the shredder, these are now pretty well rotted (see image)
my question:
Would this materal be a good mulch for my brand new built and filled raised beds? (beds are now full of compost / Pete / vermitulte mix)
They are currently empty of crops and planning on adding a good 1.5 - 2 inch layer of chippings but a bit concerned that this may not be a good idea?
Any feedback please??
Thanks Neil

Thank you for the reply, I was kind of hoping the goodness would be under the mulch and this would just be for moisture retention / weed control and it would just compost into the beds over time?
Due to the time of year I am expecting most of the bed space to be empty till the spring time appart from some seeds I have germinating in the greenhouse.

thank you for the reply:
the beds will get some planting when my seeds pop up:
Leeks
Carrots
lots of lettuce
rocket
beetroot
just not expecting to fill till next year 

I put rotted down chippings in my raised beds and I have had the best crops I have ever had.     Go for it.

Enough of the research now, I am going to try it and see how it goes, I will keep you informed, thank you all for your replies, much appreciated
