One Stop Shop vs Individual SEAI Grants

Last reviewed: October 2026

Two routes with different responsibilities

Individual Energy Upgrade Grants support eligible measures you arrange through the relevant SEAI application process. They can suit one upgrade or a staged plan. A One Stop Shop is a registered provider that assesses and coordinates a complete home energy upgrade, handles grant administration and manages the works.

The decision is about scope and delivery as well as the grant. Read the main SEAI grants guide for amounts; this page focuses on how to compare the routes.

Scope and eligibility

Individual Grants: measure by measure

Each measure has its own conditions. Insulation and controls generally use a pre-2011 build and occupancy cutoff; heat pumps use pre-2021, while solar and battery support use pre-2025. A phased project does not remove technical requirements, previous-funding restrictions or the need for approval before works.

One Stop Shop: an assessed package

SEAI requires a pre-2011 home and a post-works BER of at least B, plus a heat pump or a primary-energy improvement of 100 kWh/m²/year. The provider assesses whether your proposed package meets this. Selecting several measures in a calculator is not proof of the required outcome.

Some measures, including floor and rafter insulation, have OSS support without a standalone Individual Grant in DanannIQ. A provider can also manage some individual upgrades; ask which scheme and grant schedule the quote actually uses. See SEAI One Stop Shop: eligibility, services and grant schedule.

Coordination and payment timing

• Individual route: you select registered contractors, coordinate dates and interfaces, secure the grant offer and arrange the required completion documents and BER. Grants are paid after the requirements are met, so plan cash flow.
• OSS route: the provider handles the assessment, application, project management and completion process. The grant is deducted upfront from its price. Confirm the payment schedule and exactly what management, assessment and remedial work the contract includes.
• Both routes: you still choose the scope, review the specification and contract, provide accurate property information and confirm exclusions, warranties and responsibilities.

Which may suit your project?

For a single suitable attic insulation project or standalone Solar PV, start by checking Individual Grants. For linked wall insulation, windows and a heat pump, an OSS assessment may help coordinate fabric and heating design.

A staged route may suit someone retaining control of contractor selection and timing. A managed package may suit someone who wants one provider coordinating the work. Neither preference establishes eligibility or proves that one route will cost less.

Compare the same finished project

Ask for itemised gross quotes, eligible grant lines, the amount you must pay, required assessments and all exclusions. Compare the same insulation area, window specification, heating distribution work, ventilation, finishes and BER outcome. A lower headline after-grant price can describe a smaller scope or leave additional work outside the contract.

DanannIQ compares both routes where enough selected work and property information make that useful. Its comparison uses a common indicative project scope; it does not predict different installers’ prices, certify an energy uplift or guarantee an OSS offer. The methodology explains provisional support and cost assumptions.

Questions to settle before you proceed

1. Which scheme is proposed, and who applies and accepts the offer?
2. Which assessments demonstrate eligibility and the target result?
3. Who coordinates ventilation, insulation and heating interfaces?
4. Which works, fees, finishes and contingency are outside the price?
5. What must be paid before grant drawdown or completion?

Use the cost-planning guide to build the wider budget, then confirm final eligibility with SEAI and the chosen provider.
