Is it possible to get a wall mounted push button cistern?

Nilrem

I need to sort out the cistern in the downstairs loo, as my mother is having problems flushing it (we've gone through about 3 handles and a couple of fittings in the past couple of years).

So I'm looking to replace the cistern with a push button type, but really don't want to replace the pan as well, so I'm wondering if anyone knows if it's possible to get a wall mounted push button cistern.
I only seem to be able to find the push button cisterns as part of a close coupled toilet/cistern combo.

Answering my own question, after some more research it looks like you can get a replacement flush mechanism that does the job, rather than replacing the whole cistern.

In case it's ever any use to anyone else it looks like the Fluidmaster 5550073 (about £12 from screwfix at time of posting), should do the job and has a push button that you simply fit wherever the old flush handle was.

So it's going to be much easier, and cheaper than I was expecting if it works out, especially as I've already replaced the handle several time in the last few years at £4-5 a time.
