SEAI says a standard online application should be approved within minutes and advises allowing 4 to 6 weeks for payment after it receives compliant forms. SEAI gives no standard duration for the works, booking a Building Energy Rating (BER) assessor, completing the assessment or publishing the BER. All of those steps must fit inside the claim window printed on your offer. This page gives the published times with their sources and dates, and says where SEAI gives no timeframe.
Homeowner-managed Better Energy Homes (individual grants) only; One Stop Shop and the free Warmer Homes scheme run on different clocks. Checked against SEAI's published guidance. Last checked 4 August 2026.
SEAI says a standard online application should be "approved within minutes" after submission, and that you should receive the offer immediately; the personalised paper offer and claim forms then follow by post. A third-party walkthrough estimates 15 to 30 minutes to fill in the online form; SEAI publishes no form-filling time.
Heat pump applications have an extra step before submission: a home built before 2007 without a compliant Heat Loss Indicator needs a completed Technical Assessment first, which has no published standard duration. SEAI also publishes nothing on whether the "within minutes" wording holds when a Technical Assessment is uploaded with the application, so treat it as a standard-application statement.
Postal applications carry two conflicting official figures at once: the current Homeowner Application Guide says the offer arrives within 5 working days, while the current application form says to allow a minimum of 14 working days. SEAI has not reconciled them; plan on the longer one.

The eight-month term starts on the date the grant offer is made, not when you accept it, so delaying acceptance buys nothing. Separately, once you receive the offer you have 30 days to accept it; if a required postal acceptance form is not returned in time, that offer lapses and you must reapply.
Within the eight months you must complete the works, have the post-works BER published on SEAI's register, and get the complete claim to SEAI. One SEAI page (the BER grant page) currently says six months while the guide, the application form and the measure pages say eight. The date that governs your claim is the Date of Expiry printed on your own Letter of Offer; go by that.
If the works cannot be finished in time and none have started, you can cancel and reapply, but a new application is assessed under whatever rules and grant amounts then apply, and 2026 has already changed several. If the works or documents run beyond the validity period, the guide says you may still submit the relevant documents with a cover letter explaining the delay; SEAI's admin team will review them and consider the application for payment. That is not an extension or a payment guarantee.

SEAI publishes no standard duration for the works themselves, for booking a BER assessor, or for the BER assessment and its publication. Its guide's only timing advice is to line up the assessor as soon as you know the retrofit start date, "to avoid delaying grant payment". The published BER must exist before your claim can go in, so a slow BER booking sits directly on the critical path to payment.
One private filled 2025 single-measure pack, which is not a general duration or service standard, shows the homeowner signing the claim forms about four months after the offer, with the BER published two weeks after the assessor's signature.
SEAI says to allow 4 to 6 weeks for payment into your nominated account upon receipt of compliant forms, paid by electronic funds transfer (EFT). That allowance excludes time spent correcting incomplete forms or BER evidence, because it begins only when compliant forms are received. If a pre-payment inspection requires reworks, SEAI holds payment until it confirms the reworks, and publishes no separate duration after that confirmation.
These are individual documented cases, not a range or a typical wait. In a February 2023 insulation thread, one claimant reported payment within four weeks and another described it only as "fairly speedy". In May 2026, a heat pump claimant reported an EFT-processing email about three weeks after submitting; that is notification, not money in the bank. And the Irish Times reported one heat pump case running from October 2024 to September 2025, about 11 months, through rule-change, signature and inspection complications.

A returned Declaration of Works. If a Declaration of Works form is incorrect or incomplete, SEAI returns it and payment is delayed; the current contractor code says an incorrect or incomplete form can also result in grant refusal. SEAI says a "significant number" of these forms are returned and its contractor code says a "large percentage", but publishes neither a return rate nor an average added delay.
An inspection before payment. SEAI may inspect before or after payment. For a pre-payment inspection, SEAI may hold payment and gives two weeks' notice of the inspection date; the application terms separately require access within 14 days of the initial request unless SEAI accepts exceptional circumstances. The visit typically lasts 30 to 60 minutes depending on the home. After a pass, the request enters SEAI's next payment run, for which no duration is published. After a non-compliant result, SEAI issues a Reworks Notification: the contractor has 28 days to rectify the issues and return the declaration signed by the homeowner and contractor, and payment stays held until SEAI confirms the fixes. In 2022, the last year with detailed published figures, 18% of Better Energy Homes properties were inspected and 54% passed initially; the Comptroller and Auditor General notes the inspections were targeted and probably not representative of all work.

One Stop Shop projects are measured differently: SEAI's 2023 report puts the average One Stop Shop cycle at around 8 months from letter of offer to grant paid, up from around 5 months in 2022. That is not directly comparable with the homeowner-managed figures above because the measurement points differ, and no comparable 2024 or 2025 figure appears in the reports reviewed for this page. Warmer Homes is a separate, free scheme with its own delivery queue; nothing on this page describes it.
