SEAI offers two main routes for homeowners paying for upgrades: claim individual grants yourself, one measure at a time, or use a One Stop Shop that plans and manages a whole-home retrofit. They differ less in the grant amounts than in who does the work of co-ordinating it, when you pay, and how far the home must improve. Here’s how to choose.
The two routes side by side
| Individual grants | One Stop Shop | |
|---|---|---|
| Scope | One measure at a time | Several measures in one plan |
| Who manages it | You | A registered provider |
| Grant payment | Repaid to you after the works | Deducted from the price |
| Paperwork | You apply for each grant | Provider handles applications |
| Required result | Each measure’s own conditions | Substantial improvement and a post-works B BER |
| Home age | Depends on measure (often before 2011; heat pumps and solar before 2021) | Generally built and occupied before 2011 |
| Best for | Budget-led, staged upgrades | Older homes needing a deep retrofit |
Note on the BER target: since 24 May 2026 new certificates use the simplified A0–G scale, so the One Stop Shop’s former B2 target is now expressed as a B. See what is a good BER rating?
Cash flow is often the deciding factor
The grants themselves are broadly the same per measure; when the money moves is not. A purely illustrative example for an older semi-detached house needing attic and wall insulation, a heat pump and controls:
| Staged individual grants | One Stop Shop | |
|---|---|---|
| Total cost of works (example) | €30,000 | €32,000 incl. project management |
| Grants (example) | €17,000 | €17,000 |
| Paid by you up front | €30,000, spread over the stages | €15,000 to the provider |
| Waiting for repayment | Up to €17,000 at times | Nothing |
| Net cost | €13,000 | €15,000 |
In this example the staged route is €2,000 cheaper, but needs the homeowner to fund the full cost of each stage and to co-ordinate the order and contractors. The One Stop Shop costs more but needs half the cash at any one time and one point of contact. Your own quotes decide the real gap.
How each route works
Individual grants
- Choose a measure, check eligibility and get quotes from SEAI-registered contractors.
- Apply, wait for approval, then do the works.
- Pay the contractor; claim the grant; repeat for the next measure.
Step-by-step detail, deadlines and paperwork are in how to apply for an SEAI grant.
One Stop Shop
- Contact a registered One Stop Shop provider; they assess the home (including a BER).
- They propose a package of measures to reach the required improvement, with a price net of grants.
- You agree the plan; they manage the applications, contractors and sequencing.
- A post-works BER confirms the result; you pay the provider the balance.
Which suits you?
| Your situation | Usually the better fit |
|---|---|
| One measure now, more later | Individual grants |
| Comfortable managing contractors | Individual grants |
| Home already partly upgraded | Individual grants |
| Older home needing several measures | One Stop Shop |
| Can’t fund the full cost while waiting for repayment | One Stop Shop |
| Want one plan and one point of contact | One Stop Shop |

Questions to ask a One Stop Shop provider
- Which measures are in the plan, and why in that order?
- What pre- and post-works BER do you expect, and what happens if the target isn’t reached?
- What is the total price, the grant deducted, and the balance I pay — and when?
- Which parts are subcontracted, and who is responsible for the work’s quality?
- What warranties apply to each measure, and who handles aftercare?
- What disruption should I plan for, and for how long?
Whichever route you choose, compare like for like with our quote checklist, and keep the fundamentals in mind: insulate first, then heating, then generation.
