What about a seismic table, such as those used for lab gear/electronics?
Can't recall the brand of the ones I used in the late 70's (doing R&D on a specific product for a couple of EE's who manufactured medical equipment), but those were rather involved using air pumps.
Here's a simple one from a quick Google search, but assume that gobs/varieties of them must be available in the UK (I'm in the USA).

I used them on cement slab floors (not certain how they would perform on a lossy floor).
