is theres a way of actually having a cylinder inline with the comb DHW

The only way you can use the hot water tank aswell as combi is by linking the coil to heating circuit using a motorised valve and its own controls. and as long as tank Is fitted by g3 engineer and hot water circuits are totally separate . Part of the buildings hot water can be fed from tank and other half from boiler.
It's quite scary your asking if hot waters can be linked if your a plumber.

Thats what i proposed Separate Systems. But the customer keeps asking, So i thought just to make sure ask.

A combi would never hear the flow from cylinder but boiler can be used as back up.

Have they also invested in the solar thermal?

If so consider something like the Grant combisol Solar Water Heating. Combine Your Existing Heating With A Grant Solar Heating Solution | Grant UK

p.s. you need to be seperately certified to install solar if they want to get paid for it.

Plumbing it will be fun with that long run though...... as the combisol works the other way round from what you're thinking...
