The cavity wall grant for an apartment
An apartment gets €700 from SEAI for cavity wall insulation, or €900 on the higher rate. The job typically costs €1,036, so about €336 is left to pay, or about €136 on the higher rate. Every outside wall has to be insulated, and the home must have been built and first lived in before 2011.
The grant, who applies in a block, and the management company's part.
Free, no obligation. One registered installer prices it, not five.

Who applies in an apartment block
The owner of the apartment applies, and so can a company that owns the building, including an owners' management company. The grant needs every outside wall of the home fully insulated, and in a block the outside walls are shared fabric, so the management company is part of the decision even when you apply for your own apartment.
13% of households in Ireland live in an apartment (Census 2022), most of them in Dublin.
Check your cavity wall grant
Four quick taps. You see your grant as you go, then what the job typically costs after it, the BER and your next step. Your number is only asked for at the end, if you want a price.
An apartment built before 2011, no earlier wall grant: a €700 grant, and the job typically costs €1,036, so about €336 is left to pay.
How this is worked out
SEAI pays a fixed cavity wall grant for each house type, and a higher fixed amount to homeowners on certain welfare payments and to landlords with a HAP or RAS tenant. The typical cost is the median price of cavity wall insulation for your house type across thousands of grant-funded jobs, and the post-works BER is its median price less its own grant. Your installer prices your walls after a look: it's a guide to plan with, never a quote. SEAI decides every grant.
Before you apply
- Ask the management company whether the walls are cavity walls and whether a block-wide job is planned.
- Check the year: built and first lived in before 2011.
- Check for an earlier wall grant on your MPRN.
