Made one of the best decisions of my life when I renovated a 1970's bungalow to incorporate disabled access throughout and whilst doing this insulated as much as I could at the time in anticipation of our retirement.
We have lived here now for a couple of years with an MVHR system. Now with a grey water system feeding loos and/or garden and a solar hot water system - presently on trial - both run on photovoltaics.
Please be aware I have designed and installed all these myself sometimes following convention sometime radical. I have been in construction for over 30 years.
Happy to share my experiences if it helps. Hope to gain further knowledge about the ASHP system I am designing.

Oh and we have an electric car and happy to discuss the results of using that.
