ASHP supplier options - help me understand the differences

[Moonshine]

I have been quoted with two different 9 Kw ASHP's for my build from two different local suppliers, both similar units but based on different parts.

 

This is going to be a non RHI / MCS installation.

 

Supplier 1 (Mitsubishi Ecodan PUZ-WM85VAA) as below for £6.3k + cost for additives and commissioning (another £1k for both)

 

 

Supplier 2 (LG MONOBLOC R32 SINGLE FAN) as below for £4.5k

 

 

It seems that the two options are based on different units, the ecodan looks the premium, can anyone help assessing the two different packages, and anything missing out that i need, or an over spec?
