BER Ratings in Co. Mayo

Mayo's BER ratings reflect some of the most exposed housing in Ireland. Coastal and island homes from Achill to Belmullet face strong Atlantic winds and rain, and older bungalows and cottages there often rate in the E to G range. Homes in Castlebar, Westport and Ballina built in recent years usually rate much higher. Holiday lets in Westport and Achill must display a valid BER rating when advertised, and insulation, airtightness and heating upgrades are the most effective ways to improve a Mayo home's grade.

With 37 SEAI-registered BER assessors serving 36 towns and areas across County Mayo, BerCert.com makes it easy to find a local BER assessor. To date, over 1,100 homeowners in Mayo have requested BER quotes through our platform.

The New BER Scale: A0 to G

Since 24 May 2026, every new BER is rated on a simpler 8-band scale. Where does your home land?

New top rating
Most efficientLeast efficient
8 bands, down from 15 A0 = no fossil fuels Older A1–G certs valid for 10 years

What Your BER Rating Means

Your rating shows how much energy your home needs for heating, hot water, ventilation and lighting, and what it costs to run.

A0 – A

Highly efficient

Very low energy use and running costs. A0 homes are highly efficient and use no fossil fuels.

B

Efficient

Typical of newer or well-upgraded homes, with lower heating bills. Often the target rating for home energy upgrades.

C – D

Average

Insulation, windows or heating upgrades can usually move a home in this range up the scale.

E – G

Least efficient

Higher energy use and bills. These homes have the most to gain from SEAI grants and energy upgrades.

BER Certificate FAQs

Quick answers to the questions homeowners ask us most.

Get BER Quotes
What is a BER rating?
A BER (Building Energy Rating) shows how energy efficient a home is, on a scale from A0 (most efficient) to G (least efficient). It is calculated by an SEAI-registered assessor and comes with an advisory report. Read more
What does each BER rating mean?
A0 and A-rated homes are the most efficient and cheapest to heat. B and C ratings are common in newer or upgraded homes, while D to G usually point to homes where insulation, windows or heating upgrades would make a real difference. Read more
How can I improve my BER rating?
Attic and wall insulation, draught-proofing, better windows and a more efficient heating system all improve your rating. Your advisory report lists the changes that will make the biggest difference. Read more
Do I need a new BER after upgrades?
A BER is valid for 10 years, but if you have added insulation, new windows, an extension or a new heating system, a new BER will reflect the work and may give you a better rating. Read more
BER ratings and SEAI grants
Many SEAI home energy grants require a BER before or after the works, to record your starting point or confirm the improvement. Our assessors can provide the BER you need. Read more
How much does a BER rating cost?
The price depends on the size, location and features of your home. Compare quotes from local SEAI-registered assessors to find the best price. Read more
