Recent Updates

For recent updates to the MCS Installation Database, please see below.

The MCS Installation Database (MID) was unavailable on Monday 3rd September 2018 from 09:30 to 13:30, due to system changes to implement the Per Installation fee increase.

For further information please see this article.

On 28th March 2018 a change to the MCS Installation Database (MID) was implemented to bring MCS certificates in line with incoming changes to the Renewable Heat Incentive (RHI). This means that some additional questions will appear in the MID, when generating (and amending) MCS certificates. On 7th February 2018, the Department for Business, Energy and Industrial Strategy (BEIS) laid regulations to implement reforms to both the Domestic and Non-Domestic Renewable Heat Incentive (RHI) schemes before Parliament.

The date when the new regulations come into force is dependent on parliamentary processes and is not yet known. The changes to the MID are introduced prior to the regulations coming into effect to enable installers to register installations and generate MCS Certificates in line with the new requirements. Where the owner applies to the RHI scheme after the new requirements come into force, installations must meet the new requirements.

The MCS Installation Database (MID) will be undergoing maintenance and will not be accessible from 17:00 on Thursday 27th April 2017. We expect the website to be unavailable for 30-60 minutes.

As part of the maintenance work, MCS will be updating the MID to allow MCS Contractors to input multiple heat products of the same technology type and product code on the same MCS certificate.

Please do not try to access the database during this time as you will be unable to generate certificates and it is unlikely that any MCS certificates will be sent out.

We apologise in advance for any inconvenience this may cause.

The MCS Installation Database (MID) underwent maintenance on Thursday 8th December from 4.00pm to 4.30pm. This was for essential updates to the database.

The MCS Installation Database (MID) underwent maintenance on Monday 6th June 2016.

As part of the maintenance work, MCS updated the MID to allow MCS Contractors to select which MCS 012 products (roof mounting kits) they have used with their Solar PV installations. This is mandatory for Solar PV installations.

MCS Contractors installing Solar Thermal products may also select MCS 012 products if they wish to do so.

The MCS Installation Database (MID) underwent maintenance on Friday 4th December. During this maintenance window the MCS installation certificate was updated to include installer’s Trading Standards Institute (TSI) consumer code membership details.

Since 5th November, when you create a MCS Certification you are asked to clarify whether the installation is domestic or non-domestic, and to provide further details regarding the insurance warranty provider and insurance policy if applicable.

The changes are detailed below:

First new question

“Is the installation intended for domestic or non-domestic use?”

  • Domestic
  • Non-Domestic

Second set of questions

If non-domestic has been selected, an option will appear for you to indicate that no insurance policy has been issued.

For domestic installations or certain non-domestic installations, the details below must be provided:

Insurance Warranty Provider Select from a drop down list of providers
Insurance Policy or Certificate Number Enter the insurance policy or certificate number
Insurance Policy or Certificate Start Date Enter the insurance policy or certificate start date

We have created a FAQs document regarding the Insurance-Backed Workmanship Warranty, which you can access here.
