We have one quote at the moment of £10k (plus VAT to reclaim) for a 11.5kW Mitsubishi with a 250 litre Kingspan tank.

 

You can get an 11.5kw Mitsubishi with a 250L Mitsubishi tank for £4600 + VAT from Secon. https://www.seconsolar.com/mitsubishi-pre-plumbed-standard-cylinder-package-3364-p.asp

They are trade only but should give you an account if you let them know you are a self builder. If you have a Mitsubishi registered installer locally who will install the ASHP, then this would would work out a more cost effective approach. 

 

I have a ASHP with oversized radiators. The system works very well, but my house is well insulated and airtight.
