Accreditations

## Certified, registered, and insured. Every time.

MCS certification isn't a box-ticking exercise — it qualifies your system for Smart Export Guarantee payments and government grants. Our installers are also NICEIC-approved and TrustMark-registered, and every install is fully insured.
