Answer a few quick questions about your home to see your SEAI grants and savings — takes under 2 minutes.
What type of home are you upgrading?
When was it built?
This drives the default insulation values. Check your BER cert or deeds if unsure — the closer the better.
How big is your home?
Choose a typical size below, or specify the exact floor area yourself.
Choose a typical size
Or specify your own size
Number of storeys
How many external doors?
What best describes your walls?
This is the single biggest factor in your heat loss. Pick the closest — we'll use the standard value for your age band if unsure.
How well is the attic insulated?
Attic insulation is usually the easiest and cheapest win. If you have a flat roof or no attic, pick the closest.
What type of windows do you have?
We've pre-selected based on your build year — change this if windows have been replaced since.
How much of the external walls are windows?
Most Irish homes are Low or Typical. A house with a large rear extension or lots of glass would be High. Not sure? We'll assume Low (15%) unless you pick a different option.
Every upgrade you choose is reflected instantly below.
Wall insulation options explained
CWI means cavity wall insulation, injected into the gap between the walls. IWI means internal wall insulation, fitted to the inside face of the wall. EWI means external wall insulation, fitted to the outside of the wall.
