Check whether your solar installer is MCS certified.
MCS certification is one of the most important credentials to verify when considering a domestic solar installation in the UK, but it is not the only thing worth checking.
Installer or scheme details are mentioned.
Check the current public register directly.
Make sure the contracting company matches.
What to check
- Check the installer on the MCS register
- Check RECC or equivalent consumer-code membership
- Confirm company identity matches the quote
- Review deposit and workmanship protection
- Check the exact contracting entity
Why MCS matters
MCS provides certification for low-carbon products and installers. For domestic solar, it is widely used as evidence of recognised installation standards and is relevant to access to export arrangements such as the Smart Export Guarantee.
Do not stop at one badge
Check the company named on your contract, not simply a logo on a brochure. Consumer-code membership, warranty protection and clear contracting information remain important.

Frequently asked questions
Does MCS certification guarantee a good installer?
No certification can guarantee future workmanship or service. It is an important credential to verify alongside other checks.
Where can I check MCS status?
MCS maintains a public Find an Installer service on its official website.
We aim to distinguish information stated in a quotation, calculations we can reproduce, public consumer guidance and things that cannot be known without a property-specific assessment. We do not accept payment from installers to change the outcome of a quote check.
