Always verify your contractor is currently SEAI registered before signing any contract. Registration status can change.

A deposit is normal — most Irish contractors ask for between 30 and 50 percent upfront to cover materials, especially for heat pumps and solar. That is standard practice. What matters is protecting yourself: get a written contract before paying anything, tie the final payment to completion of the work, and never pay the full amount upfront. Pay by traceable means, not cash.

If a contractor visited your home to sign the contract, you usually have a 14 day cooling-off period to cancel under EU consumer law. Note: if you ask the contractor in writing to begin work during this period, you may lose some or all of this right. Always check before signing.
