BER Requirements for Landlords 2026
No minimum BER standard is in force yet, but the March 2026 rental law changed what BER actually does for landlords: rent comparators, a rent-reset incentive, and full SEAI grant access.
What’s Actually Required Today
Every property offered for rent in Ireland must have a valid BER certificate. The rating must appear in all advertisements and be provided to prospective tenants. There is currently no minimum BER standard in force, any valid certificate satisfies the legal requirement, regardless of rating.
The Housing for All 2025 target passed without legislation. A minimum standard for private rentals has been promised since 2021 but never legislated. The direction of travel points toward one eventually, driven by EU energy targets, but no date or band is currently confirmed.
Current Requirements
- A valid BER certificate is required to advertise or let a property, no specific rating is required
- The rating must appear in the advertisement, Daft.ie and other property sites included
- The certificate must be provided to prospective tenants
- Converted properties with multiple units need a separate BER for each individual unit
- Enforcement sits with the local Building Control Authority
Improve Your BER by 7 Levels, Reset Your Rent
Under the Residential Tenancies (Miscellaneous Provisions) Act 2026, improving a property’s BER by 7 or more levels qualifies as a “substantial change.” This permits resetting rent to market rate outside the standard 6-year review cycle, a direct financial incentive for a significant retrofit, separate from grants, tax relief, or energy savings.
What Changed for New Tenancies
These rules apply to tenancies created from 1 March 2026 onward. Existing tenancies continue under previous rules, except the rent cap, which applies universally.
BER-Based Rent Comparators
Landlords must reference three comparable RTB Rent Register properties with similar floor area, bedrooms, and BER when setting rent for a new tenancy.
RTB Registration Requires BER
The BER rating must be provided when registering a new tenancy with the RTB.
Rent Pressure Zones Abolished
Replaced by a national system capping annual increases at 2% or CPI inflation, whichever is lower, nationwide.
Rolling 6-Year Tenancies
New tenancies become Tenancies of Minimum Duration (TMD), lasting 6 years and automatically renewing.
Grant and Tax Relief Eligibility
Landlords qualify for all individual Better Energy Homes grants on the same terms as owner-occupiers, insulation, heat pump, solar, windows, and doors are all available.
| Scheme | Landlord Eligibility |
|---|---|
| Individual Better Energy Homes grants | Yes, same terms as owner-occupiers |
| One Stop Shop deep retrofit | Yes |
| Warmer Homes Scheme | No, reserved for low-income homeowners only |
| Rental income tax deduction | Up to €10,000/property/year, up to 3 properties, works 2026–2028 |
Limitations and Practical Traps
No minimum standard is enforceable today. Despite years of policy signalling, landlords aren’t legally required to hit any particular BER band right now.
Multi-Unit Conversions Need Individual Certificates
A single whole-house BER doesn’t satisfy the requirement for each separate flat in a converted property.
The Rent Cap Applies Even to Existing Tenancies
Landlords with pre-March-2026 tenancies still need to apply the 2%/CPI cap from 1 March, even though other elements of the new law don’t apply retroactively.
Warmer Homes Is Off-Limits
It’s the one SEAI scheme landlords can’t access, reserved for low-income owner-occupiers.
What to Do Next
Check Your Property’s BER
Search the National BER Register by address to confirm it’s valid and current.
If Setting Rent for a New Tenancy
Identify three comparable RTB Rent Register properties with similar floor area, bedrooms, and BER.
Consider a Substantial Retrofit
A 7-plus-level BER improvement permits a rent reset outside the 6-year cycle, on top of grants and tax relief.
