It's certainly possible from a technical point of view:

but I do not know if it is either a matter of Octopus policy or an MCS requirement to fit a new HW system. Quite typical overengineering IMHO, I bet the cost is additional to their "standard" installation for £3k.

 

I have asked for an Octopus quotation but they do not have installers in my area yet and I fully expect to end up doing it myself.

Surely, they can simply set the ASHP to Heating only?  Although, I guess they have trained their teams to do an 'install' which would always include the plumbing to the DHW tank coil.

Maybe Octopus have been following this thread and want to encourage the OP to use his PV to run the HP and then export his surplus. But at least he should be given the choice, it is not very eco-friendly to scrap off new kit that is working satisfactorily.

 

AIUI they are not offering to plumb into his existing coil, it may not be big enough or may not even exist, it is described as a "direct" UV tank.

Do you have room for a second cylinder in series with the one you already have?  The one cylinder would act to "warm up" the cold feed for the second cylinder.  I don't see that Octopus could object to that and that way you could keep what you've got.
