SEAI contractor matching · Verified May 2026
Get matched with the right SEAI-registered contractor in your county
SEAI gives you registers. HomeUpgrade.ie helps you pick the right installer type, check the grant sequence, and request contact from a suitable provider before you waste time sorting a cold list yourself.
BER assessor
SEAI-approved BER assessor. A current Building Energy Rating is required before nearly every SEAI grant.
Best fit: Start here if you do not have a current BER
Heat pump installer
SEAI-registered installer for an air-to-water or ground-source heat pump. A technical assessment is required before applying.
Best fit: Fabric upgrades (attic / walls / windows) usually need to be in place first
Solar PV installer
SEAI-registered solar electricity installer for the Solar PV Grant (up to €1,800). Pre-2021 owner-occupied homes qualify.
Best fit: Quick standalone upgrade — no fabric prerequisites
Solar water heating
SEAI-registered installer for a solar thermal hot-water system. Separate €1,200 grant; not the same as Solar PV.
Best fit: Pair with an existing cylinder — independent of fabric works
Windows & doors installer
SEAI-registered installer for the Windows & Doors Grant (live since March 2026). Pre-2011 homes qualify.
Best fit: Adequate attic and wall insulation must already be in place
Attic insulation contractor
SEAI-registered installer for attic / roof insulation. Standard grant is up to €2,000; enhanced rates may apply.
Best fit: Highest-impact first step — usually the cheapest upgrade for the biggest BER bump
Cavity wall insulation
SEAI-registered installer for cavity wall insulation. Suited to homes built ~1940–2007 with a cavity wall.
Best fit: Fast install (1–2 days) — confirm cavity type before quoting
External wall insulation
SEAI-registered installer for external wall insulation (EWI) — wrap the outside of the home. Higher cost, biggest fabric impact.
Best fit: Major works — usually part of a deep retrofit
Heating controls installer
SEAI-registered installer for the Heating Controls Grant (€700). Smart thermostats, zone controls, programmers.
Best fit: Quick standalone upgrade — low disruption
One Stop Shop (full retrofit)
SEAI-registered One Stop Shop provider — manages your full home retrofit from survey to grant payment.
Best fit: Best for multi-measure deep retrofits aiming for B2 BER or better
HomeUpgrade.ie does not approve grants. Your home is not grant-approved yet. Works must not start before SEAI written approval. You can withdraw consent at any time.
Important: Using a contractor who is not registered with SEAI for the specific measure permanently disqualifies your grant claim. Always verify SEAI registration before agreeing to any work.

SEAI registered contractors — FAQ
Verified May 2026. Always confirm a contractor's current SEAI registration at seai.ie before agreeing to works.
How do I find an SEAI-registered contractor?▾
SEAI publishes a register of contractors approved for each grant measure (insulation, heat pump, Solar PV, windows & doors, etc.). You can search the official SEAI contractor register at seai.ie. HomeUpgrade.ie helps you understand which contractor type fits your home and route, and connects you with suitable SEAI-registered installers if you ask us to.
Are HomeUpgrade.ie contractors guaranteed to be SEAI-registered?▾
HomeUpgrade.ie summarises publicly available contractor data and only routes enquiries to providers who indicate they are SEAI-registered for the relevant measure. We are independent of SEAI and we do not certify contractors — always verify a contractor's current SEAI registration directly at seai.ie before agreeing to any works.
Do all SEAI grants require a registered contractor?▾
Yes. SEAI individual grants (Better Energy Homes), the One Stop Shop, and Solar PV all require works to be carried out by a contractor registered with SEAI for that specific measure. Using a contractor who is not registered for the measure permanently disqualifies your grant for that upgrade. The Warmer Homes Scheme is different — SEAI appoints the contractor for you.
Can I get more than one quote from SEAI-registered contractors?▾
You should. SEAI itself recommends getting at least three quotes before choosing a contractor. HomeUpgrade.ie can connect you with up to three suitable SEAI-registered providers in your county for a pre-application quote — works must not start until SEAI has issued written approval.
Where can I check if a contractor is SEAI-registered?▾
The official SEAI contractor register is on seai.ie under Home Energy Grants → Find a Registered Contractor. Always check the contractor is registered for the specific grant measure you are claiming (e.g. heat pump, attic insulation, solar PV) — registration for one measure does not cover others.
