Before you contact a contractor
- Run the grant navigator first — knowing which grants you qualify for keeps quote conversations honest.
- Confirm the contractor is currently SEAI-registered for the specific grant measure (insulation, heat pump, solar etc.).
- Apply for the SEAI grant before any work starts. Early-started works are permanently disqualified.
- Get at least 3 quotes from SEAI-registered contractors before signing anything.
SEAI contractors in Sligo — common questions
How do I find SEAI registered contractors in Sligo?▾
This page lists SEAI-registered contractors and energy professionals serving Sligo, grouped by measure — insulation, heat pumps, solar PV, windows & doors, BER assessment and One Stop Shop providers. The authoritative source is always SEAI's own register at seai.ie: check the contractor is currently registered for the specific grant measure before agreeing to any works.
Do I need an SEAI-registered contractor for grant work in Sligo?▾
Yes. SEAI individual grants, Solar PV and the One Stop Shop scheme all require works to be completed by a contractor registered with SEAI for that specific measure, anywhere in Ireland including Sligo. Using a non-registered contractor permanently disqualifies the grant for that upgrade.
How many quotes should I get from contractors in Sligo?▾
SEAI recommends getting at least three quotes before choosing a contractor. HomeUpgrade.ie can connect you with up to three suitable SEAI-registered providers covering Sligo — run the grant checker first so quote conversations start from your actual eligibility.
What SEAI grants can homeowners in Sligo claim in 2026?▾
The same national schemes apply in Sligo as everywhere in Ireland: attic and wall insulation grants, the heat pump grant (up to €6,500, or more with the full bundle), Solar PV (up to €1,800), solar water heating, heating controls, windows & doors, the fully funded Warmer Homes Scheme, and One Stop Shop retrofits. Eligibility depends on your home's age, BER and route — the free grant checker resolves it in about two minutes.
