Dream setup for our place - maybe in 10 years time (fitted new boiler in 2020 as couldn't face major renovation required to get the place efficient enough for ASHP)
- insulate floors
- insulate some external walls (terrace, so not too bad)
- fit underfloor wet heating throughout
- re-fit loft conversion with more effective insulation
- ASHP on the back, under the deck
- solar panels on the garden office roof feeding the immersion heater
- additional panels on the flat roof if possible
- storage battery somewhere
Gonna be wallet crushing

It's certainly a big commitment but sounds like a good plan!
The one thing I'd say is if you're going to get an ASHP anyway you'd be better off to let the ASHP do the DHW and direct the Solar PV to running the ASHP instead of an immersion. Every 1kw of energy you put into the immersion will give you approximately 1kw of DHW heating but if you put 1kw into the ASHP you'll be getting c.3-3.5kw of DHW heating...
