The system you are proposing Is what I personally regard as the best in the main domestic market at present.
Assuming it is a straightforward replacement job I would expect to charge around £2000 + VAT to install labour only including pipe and fittings, but would not offer any warranty call backs on the kit you supply. You would have to deal direct with the manufacturers or pay my call out.
Saying that I've yet to have a fault with this set up once running, other than the one 2 weeks ago where the VR65 was dead out of the box. Luckily I carry spares.
Buy getting an installer to supply and fit you will have him available for any call backs for 2 years and you will save a little bit because he will charge a small amount, in your case I guess about £400-£500 at 5% VAT on the bits he would classify as 'energy efficient controls'. You, if you supplied everything would lose this advantage.
