Who gives you a certificate or a copy of the install id for the inverted heating system?

[CalvinHobbes]

Hello, I am chasing up certs for Building Control in NI. One of the things is a copy of the install id for the inverted heating system.

We had our builders who have 2 family members who installed our underfloor heating and ashp. Then they had a separate guy commission the heat pump.

The builders/plumbers a;so installed our water tank/plumbing.

Who is meant to give this certificate or copy of the install id?

The builders or the commissioners and where can i get a blank copy for them to sign?

Thanks

 unvented maybe?

yup, I can't read my writing lol it must be unvented

Assume NI same as rest of UK and the unvented cylinder would require a G3 certificate to cover the unvented cylinder install.

 

The heat pump install would be asking the commissioning person for a commissioning certificate.
