Registering your MCS installation on the MID

29 January 2024

As an MCS certified contractor, registering your installation on the MID (MCS Installation Database) and raising the MCS certificate is confirmation of compliance with our Scheme requirements.  

It shows us that you have installed the renewable energy or heating system in line with MCS Installation Standards, which represent industry levels of quality. 

As an MCS certified contractor, it is paramount that you are following the correct procedure when registering your installation on the MID.  

The installation shall only be registered on the MID when the installation is fully complete and commissioned, and not before. The registration shall only be done by the MCS certified contractor who entered into the contract with the customer.

In relation to heat pump systems, commissioning should take place when the full system that the heat pump unit will operate with has been installed, including the emitters.

The registration of the installation on the MID shall be completed no later than 10 working days after commissioning has taken place, and the MCS certificate shall be included in the handover pack provided to your customer.

It’s your responsibility as an MCS certified contractor to ensure that your MID records are accurate. We therefore suggest routinely checking your installation records. If there are any installations that should not be registered, please contact the MCS Compliance team who can process a certificate withdrawal request. You can contact the MCS Compliance by emailing mcscompliance@mcscertified.com
