Home Energy Group uses The IAA Microgeneration Guarantee for qualifying MCS-completed microgeneration installations. This page explains the public information currently available about that protection. The guarantee issued for your own installation, its certificate and the IAA scheme terms are the documents that control your cover.
The IAA Microgeneration Guarantee
The Insurance and Warranty Association (IAA) provides an MCS-approved financial protection product called The IAA Microgeneration Guarantee. The IAA’s current public leaflet states that it provides six years of cover for every installation completed under MCS.
That is why HEG will confirm the protection relevant to your project in its pre-contract information and handover documents. Cover is not assumed merely because a product is shown on this website or a quotation has been discussed.
What the guarantee is designed to do
The IAA describes this as remedial protection, not compensation, for a failure in workmanship or design. Its public information says that the remedy remains available if the original installer has ceased trading.
This is distinct from your statutory consumer rights, HEG’s contractual obligations and the manufacturer warranties for panels, batteries, inverters, heat pumps or other equipment. Those protections have different terms and should be read separately.
Which installations may be eligible?
MCS currently lists The IAA Microgeneration Guarantee for eligible Solar PV, Battery Storage, Air Source Heat Pumps, Ground Source Heat Pumps and Solar Heating installations. Eligibility, registration and the exact scope still depend on the completed installation, the relevant MCS process and the issued IAA documentation.
HEG will not represent an EV-only installation, a survey, a quotation, an unregistered project or any work outside the applicable scheme scope as being covered.
How cover is put in place
The IAA’s published product journey shows post-install evidence being submitted, an ISA reference being created and the guarantee then being issued. Please retain your quotation, completion records, MCS documentation, handover pack and issued IAA guarantee together.
If you have a question about whether cover has been issued for a completed HEG project, contact us with your property address and relevant reference. We can help locate the correct next step; we will not substitute a website statement for the actual certificate.
Raising a concern
Please contact HEG first so that we can investigate and respond. If a matter remains unresolved, MCS publishes its current consumer complaints route. The IAA guarantee/certificate will set out the applicable guarantee process, including the conditions, exclusions, evidence and remedy for an individual case.
Important limits
This overview does not create cover or alter a guarantee. It does not promise deposit protection, cash compensation, a product warranty, a performance outcome or cover for a particular installation. The issued IAA documentation and scheme terms prevail.
