Anyone got experience using this? I've found a local company who can supply 3 cubic meters for £80 which sounds like a pretty good price. Previously I've been using wood chip mulch which I like because it is fairly long lived so doesn't need frequent replacing. How long is mushroomcompost likely to last before needing replacing? My instinct is that it would be comparatively stable.
Alternatively I can get a load of wood chip and a load of mushroom compost and spread a layer of each - fertility from the compost and longevity form the chips.

Because fungi have already taken a turn or two breaking it down, in one sense it can "be comparatively stable", since it is well on its way to being rich soil. On the other hand, the fertility may be low because a lot of the nutrients that were in it may already be used up.
I would second the idea of using a mix of both the mushroom compost and the wood chips, because then you are amending with different elements of the succession. Wood chips attract the primary decomposer fungi, while the mushroom compost feeds the fungi that feed on decaying fungi that fed on other fungi.
