Due diligence

How to check any installer — including us

  1. 01

    Ask for the certificate number

    Not the logo. A registration number can be checked; an image on a website cannot.

  2. 02

    Search the scheme's own register

    Check the relevant scheme's public register or ask the scheme to confirm the company's current membership and scope.

  3. 03

    Check the scope

    A certification can cover solar but not battery storage, or electrical work but not microgeneration. Confirm it covers your job.

  4. 04

    Confirm the trading name matches

    The registration should be held by the legal entity that will sign your contract.

  5. 05

    Check insurance-backed warranties

    Ask who underwrites the workmanship warranty and what happens if the installer ceases trading.

  6. 06

    Read the contract before the deposit

    A consumer code sets out deposit protection and cancellation rights. Make sure yours is in writing.
