BER assessments in Dublin
A Building Energy Rating assessment costs a median €280 in Ireland, and SEAI pays €50 towards it. You'll need one after any grant-aided work is finished, because SEAI won't pay a grant until a post-works BER has been done.
So everyone claiming a grant buys one of these, whether they planned to or not.

What does a BER assessment cost?
The cost barely moves with the size of the home, which is unusual on this site — every other measure scales hard with the house. An assessment is a survey, and a bigger house takes a little longer to survey rather than a lot more material to insulate.
So the figure beside this is close to what you will pay whatever you live in, and a quote well above it is worth a second look.
Costs and grant from SEAI's published median costs, checked 15 August 2026. A median is the midpoint: half of assessments cost less and half cost more.
Cost against the grant
| Home | Median cost | Grant | You pay |
|---|---|---|---|
| Detached house | €280 | €50 | €230 |
| Semi-detached or end of terrace | €280 | €50 | €230 |
| Mid-terrace house | €275 | €50 | €225 |
| Apartment | €245 | €50 | €195 |
Why you need one, and when
The BER is the measurement SEAI settles against. On the individual grant route the order runs:
- Get quotes
- Apply for approval
- Have the work done
- Arrange the post-works BER
- Submit the evidence
- SEAI pays
It is the second-last step, not the first.
On the One Stop Shop route the provider arranges it as part of the package, because the whole route is aimed at getting the house to a minimum B rating and somebody has to certify that it got there.
You might want one before you start too, for a different reason. It tells you what the house is actually losing heat through, which is the difference between guessing and knowing. That one's optional, and you'd be paying for two assessments.

What the assessor actually does
A registered assessor surveys the fabric and the services:
- Wall construction, and whether there is anything in it
- Attic depth
- Windows and doors
- The heating system and its controls
- Hot water and ventilation
They measure and photograph, and they work from what the building is made of.
That last point catches people out. A BER rates the house, not the household. Two identical houses get the same rating whether one's empty all winter and the other runs the heating constantly, so you can't improve a rating by being careful. You improve it by changing the building.
What gets surveyed
- Wall construction, and whether there is anything in it
- Attic depth
- Windows and doors
- The heating system and its controls
- Hot water and ventilation
They measure and photograph rather than test. The rating reflects what the house is built from, not how you use it.
What counts as a good rating?
The scale runs A1 at the top to G at the bottom. For grant purposes the number that matters is B2. SEAI's One Stop Shop route exists to bring homes to a minimum B, and the building regulations threshold for larger jobs asks for B2 or for a heating system and attic insulation that already meet the regulation standard.
Most of Dublin's pre-2011 stock sits a long way below that, which is the whole reason the grant schemes exist. Getting from a D or an E up to a B2 usually means insulation and heating together rather than one measure.

The scale runs A1 down to G. Most of Dublin's pre-2011 stock sits a long way below B2 before anything is done to it, which is the whole reason the grant schemes exist.
What moves the number
In rough order of how much rating you buy per euro on a typical older Dublin house:
- Attic insulation — cheapest by a distance, and the grant covers most of it.
- External or internal wall insulation — the biggest single fabric improvement and the biggest bill.
- Heating controls and then the heating system itself, which is where the heat pump grant comes in.
If you already know which of those your house needs, the assessment can wait until the end, which is where SEAI wants it anyway.
Getting from a D or an E to a B2
On most older Dublin housing that means insulation and heating together rather than one measure. Which is the argument for the One Stop Shop route if a B rating is what you are actually after.

BER assessment questions
6 questions
How much should a BER assessment cost?
SEAI's published median is €280 for a detached house, €280 semi-detached or end of terrace, €275 mid-terrace and €245 for an apartment. Those are what registered assessors actually submitted, so a quote well above them is worth a second look. SEAI also pays a €50 grant towards it, which almost nobody mentions.
Do I need a BER to get a grant?
Yes, but after the work rather than before. Every individual grant route needs a post-works BER before SEAI pays out, so it isn't optional if you're claiming. If you're going through a One Stop Shop, they arrange it as part of the job.
How can I check the BER rating of my home?
SEAI runs a national BER register and publishes ratings on it, so if your home's been assessed since the scheme began you can find the certificate without paying anyone. It'll also be on the advertisement if the house was recently sold or let, because a BER is legally required for both.
What is a good BER rating in Ireland?
The scale runs A1 down to G, and the number that matters for grants is B2. SEAI's One Stop Shop route exists to bring a home to a minimum B, and the building regulations threshold for larger works asks for B2, or for a heating system and attic insulation that already meet the regulation standard. Most older Dublin housing sits well below that before anything is done to it.
What happens during a BER assessment?
A registered assessor visits and surveys the building fabric and services: wall construction and insulation, attic depth, windows, the heating system and controls, hot water and ventilation. They measure and photograph rather than test, so the rating reflects what the house is built from and not how you use it. Two identical houses get the same rating whether one's empty and the other has the heating on constantly.
Can I use any assessor?
For a grant, no. The assessor has to be on SEAI's register, and SEAI publishes that list. Same principle as the contractor: unregistered work doesn't get paid.
