Trusted installers

You can't buy a place on GoSolarCompare.

Other platforms list anyone who pays. We approve companies on evidence, keep commercial arrangements separate from quality indicators and remove installers who stop meeting the standard.

Our approval processApply as an installer
  1. 01

    Apply

    Installers submit company details, certifications, insurance and evidence of their work.

  2. 02

    Verify

    Our team checks the evidence against the requirements for each technology they want to offer.

  3. 03

    Approve

    Only an administrator can approve an application. Nothing is automatic and nothing can be bought.

  4. 04

    Monitor

    Expiry dates are tracked, customer feedback is reviewed and installers are periodically re-verified.
