ShamFixHire the people your neighbours trust.Something shifted in the Irish home-energy market in 2026, and for tradespeople who fit insulation, windows, heat pumps or do the electrical work around them, it is worth understanding — because the demand is real, it is documented, and a lot of it is landing as everyday private work, not just grant jobs.
This guide lays out what actually changed in 2026, why the work is not only grant-funded, why the trades shortage tilts the market in installers' favour, and where a small or new installer has the clearest run at it.

In January 2026 the government launched a new National Residential Retrofit Plan and put a record €640 million behind home-energy grants for the year, with a target of 73,000 upgrades. Homeowners responded fast. By the end of the first quarter, SEAI had processed around 29,000 applications — up 96% year on year, with applications for individual upgrades up 186% [gov.ie, April 2026].
The increase was concentrated in exactly the trades that carry out this work:
When that volume of demand enters a market in a single quarter, it does not all flow neatly through the grant system. A meaningful share spills over into private work for local installers.
It is easy to assume the retrofit boom is a grant story — that the jobs all go through SEAI-registered contractors and One Stop Shops. Much of it does. But the grant route is deliberately narrow: it requires registration, paperwork, BER assessments and approved-contractor status, and the registered supply does not stretch evenly across the country.
Around that formal route sits a large and growing private market. Homeowners who do not qualify, who want a single measure done quickly, who are topping up work the grant did not cover, or who simply want to deal directly with a local installer — that is private work, and the 2026 surge has lifted all of it. For a small installer, the private side is often the more accessible one: no scheme registration required, faster to quote and complete, and paid directly.
The other half of the picture is supply. Ireland needs an estimated 100,000 additional construction workers over the next four years to meet its housing and infrastructure targets — a 50% increase in the workforce by 2030 — and the sector is already flagging a "severe" skills shortage and an ageing workforce [thejournal.ie, citing Property Industry Ireland, February 2026].
The sector is also highly fragmented: as of recent figures, 99% of active construction enterprises employ fewer than 20 people. In plain terms, this is a market made of small firms and sole traders, with more demand than hands to meet it. For a competent installer, that is a seller's market — the constraint is not finding work, it is being found by the homeowners who need you.
Demand is national, but installers are not evenly spread. The cities have depth; rural and western counties often do not. Counties like Leitrim, Roscommon, Kerry and Donegal regularly have more homeowners looking for insulation, window or heating work than there are local installers actively quoting for it.
For a new or small installer, that imbalance is the opportunity. Listing early in a thinner-covered county means the enquiries that come in face less competition than the same listing would in Dublin. It is the clearest place to build a review base and a local reputation while the demand curve is still rising.
Three things matter for turning the retrofit surge into booked jobs.
First, be findable. Most of this private work starts with a homeowner searching or asking locally. Being listed where they look — on a marketplace, on Google, in local groups — is the whole game. 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 retrofit services on the retrofit installer leads page and be matched to local jobs.
Second, build reviews. In a trade where a homeowner is letting you into their home and paying for work they cannot easily judge, honest reviews and ratings are the strongest trust signal you have. Ask every satisfied customer for one.
Third, hold your own credentials. No marketplace verifies your qualifications for you — you list your own, and it is on you to hold the correct registration for the work you do: RGI for gas, Safe Electric for electrical, and SEAI registration if you take on grant work. Keeping those current is both a legal requirement and a selling point you can show customers.
The retrofit wave is not a guarantee of work — but for a small installer who is findable, reviewed and properly registered, 2026 is about as favourable a market as Irish home-energy work has offered in years.
Yes. SEAI processed around 29,000 grant applications in the first quarter of 2026 — up 96% year on year — backed by a record €640 million budget targeting 73,000 home-energy upgrades this year [gov.ie, April 2026]. Demand has jumped across the specific trades that do this work: over 7,000 applications for the new windows-and-doors grant, attic insulation up 81%, and cavity wall insulation up 62% year on year in Q1 alone.
For SEAI grant-funded jobs, yes — those run through SEAI-registered contractors and One Stop Shops. But a large share of retrofit work is private: top-ups, out-of-scheme jobs, and homeowners who simply want the work done directly. You do not need SEAI registration for that private work. You are responsible for holding whatever registration your trade legally requires (for example RGI for gas or Safe Electric for electrical), and for SEAI registration if you choose to take on grant work.
Demand from the retrofit wave is national, but installer coverage is not even. Under-covered counties — places like Leitrim, Roscommon, Kerry and Donegal — often have more homeowners looking than local installers available. A new or small installer listing in a thinner-covered area faces less competition for the work that comes in than they would in Dublin or Cork.
Per-lead platforms like Bark charge you for each contact whether or not you win the job. ShamFix.ie uses a subscription model — and is free for installers during Phase 1, with no per-lead credits and no commission. You list your services and an AI concierge matches you to local jobs. See the retrofit installer leads page on ShamFix for how it works.
Insulation (attic, cavity wall and external wall), window and door installation, heat-pump and heating work, and electrical services are all riding the 2026 grant expansion. The heat-pump grant alone rose from €6,500 to as much as €12,500 in February 2026, and windows grants run up to €4,000 with €800 per external door — pulling more homeowners into upgrades and creating both grant and private work for these trades.
