New build heating and electrical Installation Certificates

nxdmsandkaskdjaqd

I am in the process of buying a new build property which has solar panels, air source heat pump, heat recovery system and underfloor heating.  I wanted to know what certificates I should be looking for the work carried out.

I know there should be:

• A Domestic Electric Installation Certificate for the whole electrical installation.
• A MCS certificate for installation and equipment used on the solar panels
  

What else should I be looking for?

DNO approval for solar export.

MCS for the heat pump, although I'm not sure if it is mandatory. It is for the Boiler Upgrade Scheme but I'm not certain that it is a for a new-build. I'd want the full design specifications the heating system, though.

If you add up all the costs for connecting up to the grid, and the ever increasing fixed charges, does it make any sense to go off-grid and also avoid all the expensive certification?

The OP is buying a new build properly with all of the mentioned equipment installed, there will be no additional cost to them to make sure the installation has been properly certified by the builder or for the grid connections which would naturally be included as standard.

Going off grid with a heat pump and no batteries would be a poor move as they wouldn’t have electricity, heating, or hot water for the house when the sun isn’t out i.e. at night or throughout large portions of winter.

Insurance certificate that will cover you if your builder or installer goes bust then problems arise.

Is this something that a solicitor would pick up during the course of their pre-contract enquiries?
