I'm assuming they've also got a few in Liverpool and Warrington.

In no small part historic due to the various franchises.
Also space and power for equipment, quality of optical transmission in the network, optical power budgets, etc.

Also, where does the TV side stand with regards to regional programming? Wrexham is in the BBC/ITV Wales/S4C region, would VM have to provide the correct region (as Sky does)? I'd imagine that getting a programme feed wouldn't be too difficult, but would it limit the number of other channels available?

I'm not sure of the exact mix but it's about timing rather than anything else so in no small part it's dependent on the cables, both optical and coaxial, used.
There's core network fibre at very least close to Chester but I see nothing near Wrexham so I guess they'll either build or lease it.
Regional programming is easy and there's going to be no shortage of capacity for TV channels.
If there's room for the additional optical kit, CMTS and QAMs needed, and if optical power budgets are okay they can home both Chester and Wrexham from an existing site and have a small site or two, or some street-side cabinets, on optical regeneration/amplification duties.
Having never built an RF network I can't really comment authoratitively on the options.
