I've had a cooling/heating heatpump fitted. Adding a couple of wall units bumped the price by about £1500, although the whole thing was softened by the grant for getting rid of an oil fired boiler.
While our house is relatibvely small and we kept the units (which also do heating as well) confined to the main living space, it wasn't especially burdensome. The bulk of the work was installing the behemoth of a hot water tank!
