I’m about to embark on a ground-floor extension of a Victorian semi, and want to de-gasify the place.
What kind of costs all-in, including any grants, would I be looking at to install an external AS heat pump system, to heat a ~120m2 house?
Could mount the unit onto our exterior wall in the side passage between the neighbour’s...

What's your heating demand? You may need to improve the fabric of the building before an AS heat pump will (efficiently) give you what you need?
We're in a similar situation (terraced Victorian) and are hoping internal wall insulation, new windows and epic floor/loft insulation will be enough to only use an AS heat pump for heating and a solar battery for hot water moving forwards.

You'd be better starting with insulating it mega first as you'll need it with a heat pump.

Respectfully disagree. Modern inverter driven HPs are very quiet (I've worked in HP industry for fifteen years). I'm literally putting one in my own apartment at the moment however my outdoor unit will be in the garden as it's a ground floor apartment.
Depending on whether @revenant. can put anything on outside walls the outdoor unit could be wall mounted too... they're basically just an AC unit (of sorts and size)...
