The number beside a county is how many companies are based there or say they cover it. A company that works across a province is counted in every county of that province, because that is what it told SEAI.
What “SEAI-registered” means
A company on this register has signed up to SEAI’s terms for grant work and can claim a grant on your behalf. If you want a grant, the work has to be done by one of them.
It does not mean SEAI has inspected their work, or that we have. There is no score, no star rating and no order of merit on this site: the lists are sorted by where a company is based and what it is registered for, and nothing else.
A company can ask to be taken off these pages at any time — email us and it is done the same week, no reason needed. The register itself is SEAI’s; we only copy it.
