What SEAI publish
One waiting list, and only one. For the free upgrades scheme, SEAI publish the wait plainly: up to 24 months from applying to the work being finished, handled in order, with no way to move up the queue.
SEAI stage waits, read 2026-09-08: pre-works BER up to 12 months from application; survey up to 14 months; works complete more than 24 months (SEAI elsewhere say 24–26); final BER and inspection 2–3 months after works.
For the ordinary grants, SEAI publish only two numbers: an online application is usually approved in minutes, and payment lands about four to six weeks after complete paperwork reaches them. They also publish the dates of each payment run.
What SEAI do not publish, and what the Dáil was told
SEAI publishes no average wait for the individual grants, and none for the whole-house route. No queue length and no backlog figure. We looked at every page, the terms and the homeowner guides on 8 September 2026, and it is not there.
Ministers have given the Dáil a few averages. The last one for the individual grants is from October 2023: about 170 days from application to payment, and about 148 days for solar panels. The works sit inside that time. Nothing newer has been given, so treat it as a 2023 figure, not today's.
So be careful with any site that quotes you one, ours included. The free upgrades figures are real published numbers. The rest is either three years old or people's experience, which is not the same thing.
What we can say from the published pieces: approval is quick, and payment after the job is a few weeks. The unknown in the middle is the contractor's diary, and that is not SEAI's queue at all.
Demand is rising fast
Ministers told the Dáil that SEAI's home schemes took 29,018 applications in the first three months of 2026, against 14,836 a year earlier. A free upgrade cost just over €31,000 a home on average in that quarter.
Rising demand is why the free-upgrades wait is what it is, and why a contractor's first free date is often months out.
What actually slows a job down
- Finding a contractor with a gap. Approval takes minutes; a good installer's diary takes months. Start ringing before you apply.
- The rating at the end. Assessors are in demand and the grant is not paid until the certificate is published, not just until the visit happens.
- Incomplete paperwork. Three signatures on the declaration of works, the right bank details, and a tax clearance certificate on grants over €10,000 in a year.
- Inspection. Some jobs are picked for a check before payment. There is no published timeline for that.
- Scope changes. Changing the size, the type or the company needs SEAI's approval first. Doing it and telling them later is not a delay, it is a refusal.
Planning a realistic timeline
A sensible plan for a single upgrade on the do-it-yourself route: two to four weeks getting quotes, a day for the application, then whatever your contractor can do — commonly one to three months in our experience of the market, longer for external wall insulation in summer. Then a week or two to get the rating booked and published, and four to six weeks for the money.
A whole-house job through a One Stop Shop is a different animal. The assessment comes first, then design, then the work in stages, with the house occupied for most of it. The grant offer lasts twelve months, which tells you what SEAI expect the outer bound to be.
If you are on a qualifying welfare payment and waiting for free upgrades, you can take the higher individual grants for attic and wall insulation in the meantime without losing your place. You pay first and get the grant back, but you are warm two years sooner.
These planning figures are ours, not SEAI's. They are what we would tell a neighbour. Only the free-upgrades figures on this page come from a published source.
