ShamFixHire the people your neighbours trust.Ireland's retrofit market in 2026 is really two markets, and confusing them costs installers work. There is the grant-route market — the one the headlines describe, funded by SEAI and delivered through registered contractors. And there is a large, less-discussed private market that sits all around it. For a small or independent installer, knowing which is which is the difference between waiting for scheme approval and getting paid this week.

The grant-route market is what most people picture when they hear "retrofit": a homeowner applies for an SEAI grant, the work is done by an SEAI-registered contractor or a One Stop Shop, a BER assessment confirms the result, and the grant is paid. It is structured, funded, and growing fast — SEAI processed around 29,000 applications in the first quarter of 2026, up 96% year on year [gov.ie, April 2026].
The private market is everything else: a homeowner who pays directly for new windows without going through a grant, someone topping up insulation beyond what a scheme covered, a job that does not meet a grant condition, or simply a homeowner who would rather deal with a local installer than navigate an application. This work has always existed — and the 2026 surge in awareness and demand has made it bigger.
The grant route is deliberately gated. To deliver SEAI grant work, you must be a registered contractor, and the deeper "managed" upgrades run through a limited pool of One Stop Shops that handle the full project and claim the grant on the homeowner's behalf. Every grant job needs approval before works begin, a registered contractor, and a post-works BER assessment.
That structure exists for good reasons — it protects quality and public money. But it also means the registered supply is concentrated and does not stretch evenly across every county. For a small installer who is not registered, or who is in a rural area underserved by One Stop Shops, the grant route can feel closed off. The private market does not have that gate.
When demand jumps the way it did in early 2026, not all of it fits the grant route. Some homeowners do not qualify. Some want one measure done now rather than a managed deep retrofit. Some are paying for the part of a job a grant did not cover. And many simply want a local installer they can ring directly.
That is the private overflow, and it suits independent installers particularly well. It is usually faster to quote and complete, paid directly without scheme administration, and open to any competent installer regardless of SEAI registration. For a sole trader or small firm — and as of recent figures, 99% of Irish construction enterprises employ fewer than 20 people [thejournal.ie, citing Property Industry Ireland, February 2026] — the private side is often the more practical place to win work from the retrofit wave.
Two things decide whether the private overflow turns into booked jobs for you.
The first is being findable. Homeowners doing private work look for installers the same way they look for any tradesperson — searching online, asking in local groups, checking reviews. Being listed where they look is what gets you the enquiry. ShamFix.ie matches Irish homeowners with local installers and is free for providers during Phase 1, with no per-lead credits and no commission — you can list your services on the retrofit installer leads page and be matched to local jobs.

The second is trust, built honestly. No marketplace verifies your qualifications for you — you list your own credentials, customers judge you on real reviews and ratings, and it is on you to hold the correct registration for the work you carry out. In private retrofit work, where the homeowner is choosing an installer directly, a solid review history and clear honesty about what you are registered for is the strongest advantage you can have.
The grants get the headlines, but for a small installer in 2026, the private overflow around them is often the faster, more open road to the work.
Grant work is funded through SEAI schemes and must be carried out by an SEAI-registered contractor or One Stop Shop, with grant approval, BER assessments and scheme paperwork. Private work is everything outside that route — homeowners paying directly for insulation, windows, heating or electrical upgrades without a grant, top-ups beyond what a grant covered, or jobs that do not qualify for a scheme. The 2026 grant expansion lifted demand across both.
Yes. SEAI registration is only required to deliver SEAI grant-funded work. Private jobs paid directly by the homeowner do not require it. You are still responsible for holding the registrations your trade legally requires — RGI for gas work, Safe Electric for electrical work — and for being honest with customers about what you are and are not registered for.
Because the grant route is deliberately structured and narrow. It requires registered contractors and a limited pool of One Stop Shops, BER assessments, minimum insulation standards and approval before works begin. Many homeowners want a single measure done quickly, do not meet a scheme condition, are topping up grant works, or simply prefer to deal directly with a local installer. With applications up 96% in early 2026 [gov.ie, April 2026], the volume spilling outside the formal route is significant.
Private work starts with a homeowner searching or asking locally, so being findable is the whole game — a marketplace listing, a Google Business Profile, and local visibility. ShamFix.ie matches Irish homeowners with local installers and is free for providers during Phase 1, with no per-lead credits and no commission. You can list on the retrofit installer leads page and be matched to local private jobs.
For a small or independent installer it often is. Private jobs are usually faster to quote and complete, paid directly without scheme administration, and do not require registration with SEAI. Grant work can be valuable too, but it carries paperwork, approval timelines and registration overhead. Many installers do both — grant work where they are registered, and private work to fill the gaps and keep cash flow steady.
