Vertical borehole ground source heat pumpts

 I'm in Edinburgh, and have a small back garden.  I believe you can get
vertical borehole ground source heat pumps, rather than the usual
horizontal ones which I just don't have space for.  Does anyone have
any information about these, particularly about people who supply them
in the UK?

My feeling is that this isn't practical to do at the moment - the
market for domestic GSHPs seems too small, and vertical ones must be
even rarer.  But I'd like to know for sure.

I tought that the norm was a vertical hole.

To dig a trench is mostly an option in the countryside.

There are no differende in the heatpump units weather they use
horizontal or vertical collectors.

Talk with suppliers of heatpump, and get references to drillers. But
be sitting down when you get the estimate. It's quite expensive to get
a deep hole drilled.
