Building Energy Certificate — What Landlords Need to Know

Building Energy Certificate — What Landlords Need to Know

Energy performance certificates (EPCs) have become a central element of property management across Europe. For landlords, understanding these documents is no longer optional — it is a legal requirement in most jurisdictions and an increasingly important factor in tenant decision-making. Whether you are renting out a single apartment or managing a portfolio of properties, this guide covers everything you need to know about energy certificates, from legal obligations to practical implications for your rental business.

What Is an Energy Performance Certificate?

An energy performance certificate (known as "świadectwo charakterystyki energetycznej" in Poland) is a document that rates the energy efficiency of a building or individual dwelling on a standardized scale. The certificate provides information about the building's energy consumption, heating and cooling systems, insulation quality, and overall energy performance. It assigns an energy class — typically ranging from A+ (most efficient) to G (least efficient) — allowing tenants and buyers to compare properties on an objective basis.

The certificate is prepared by a qualified energy auditor who assesses the building's construction, materials, heating systems, ventilation, and other factors that influence energy consumption. The resulting document is valid for 10 years from the date of issue.

Legal Requirements for Landlords in Poland

Since April 2023, Polish law requires that an energy performance certificate be made available to tenants when signing a rental agreement. The key legal requirements include:

• The landlord must provide the tenant with a copy of the energy certificate or its details before or at the time of signing the lease agreement
• The certificate must be prepared by a certified energy auditor registered in the Central Register of Energy Performance Certificates
• The certificate is valid for 10 years unless significant changes are made to the building that affect its energy performance
• Failure to provide the certificate can result in a fine of up to 5,000 PLN
• The certificate must be listed in the Central Register maintained by the Ministry of Development and Technology

These requirements apply to all types of residential properties being rented, including apartments in multi-family buildings, single-family houses, and commercial spaces used for habitation.

How to Obtain an Energy Certificate

Obtaining an energy certificate involves several steps, and understanding the process helps you plan ahead and avoid last-minute delays when signing lease agreements:

• Step 1: Find a certified auditor. Look for energy auditors registered in the Central Register. You can verify their credentials on the Ministry's website. Many auditors offer online services where you provide building documentation and they prepare the certificate remotely.
• Step 2: Prepare documentation. The auditor will need building plans, information about heating and cooling systems, insulation details, window specifications, and utility consumption data. Having this information ready speeds up the process.
• Step 3: On-site assessment (if required). Some auditors conduct on-site inspections, particularly for older buildings where documentation may be incomplete. This typically takes 1-2 hours.
• Step 4: Certificate issuance. The auditor prepares the certificate and registers it in the Central Register. You receive the document within 1-2 weeks, though expedited services are available.

Costs of Energy Certificates

The cost of obtaining an energy certificate in Poland varies depending on the property type, size, and location:

• Standard apartment (up to 80 m²): 300-600 PLN
• Larger apartment (80-150 m²): 500-900 PLN
• Single-family house: 800-1,500 PLN
• Commercial property: 1,000-3,000 PLN depending on complexity

Given the 10-year validity period, this cost is relatively modest when amortized over the certificate's lifespan. For landlords managing multiple properties, some auditors offer volume discounts that can reduce per-unit costs significantly.

Energy Classes and What They Mean

The energy class assigned to your property communicates its efficiency to prospective tenants at a glance. Understanding what each class represents helps you assess where your property stands and what improvements could be worthwhile:

• Class A+ and A: Highly efficient buildings, typically new constructions with advanced insulation, heat pumps, and often renewable energy sources. Annual energy demand below 50 kWh/m².
• Class B: Well-insulated buildings with modern heating systems. Annual energy demand 50-75 kWh/m². Common in buildings constructed after 2015.
• Class C: Average efficiency, typical of buildings from the 2000s with basic insulation improvements. Annual energy demand 75-100 kWh/m².
• Class D: Below-average efficiency, common in buildings from the 1990s. Annual energy demand 100-150 kWh/m².
• Class E and F: Poor efficiency, typical of unrenovated buildings from the communist era. Annual energy demand 150-250 kWh/m².
• Class G: Very poor efficiency, usually older buildings with no insulation and outdated heating. Annual energy demand above 250 kWh/m².

How Energy Ratings Affect Rental Value

Energy efficiency increasingly influences tenant decisions and rental pricing. Research shows that properties with higher energy ratings command premiums in the rental market:

Tenants are becoming more energy-conscious for both environmental and financial reasons. A property rated class B instead of class E could save a tenant several hundred zloty per month in heating costs, making it significantly more attractive. Landlords with energy-efficient properties can justifiably charge higher rents while still offering lower total living costs (rent plus utilities).

Conversely, properties with poor energy ratings may struggle to attract quality tenants, face longer vacancy periods, and require discounted rent to remain competitive. As energy prices continue to rise and environmental awareness grows, this gap will only widen.

Improving Your Property's Energy Rating

If your property's energy certificate reveals poor performance, several improvements can boost its rating. The most cost-effective measures include:

• Window replacement: Upgrading to double or triple-glazed windows can reduce heat loss by 30-50% and often moves a property up one or two energy classes
• External insulation (ETICS): Adding thermal insulation to exterior walls is the single most impactful improvement for older buildings
• Heating system upgrade: Replacing an old gas boiler with a modern condensing boiler or heat pump dramatically improves efficiency
• Thermostat installation: Smart thermostats and thermostatic radiator valves provide precise temperature control and reduce energy waste
• LED lighting: While the impact on the certificate is smaller, switching to LED lighting reduces overall energy consumption
• Roof and attic insulation: For top-floor apartments and houses, proper roof insulation prevents significant heat loss

Many of these improvements are eligible for government subsidies and tax incentives through programs like "Czyste Powietrze" (Clean Air) or thermomodernization relief.

Energy Certificates Across Europe — A Comparison

If you manage properties in multiple European countries or are considering international expansion, it is worth understanding how energy certificate requirements differ:

• Germany: The Energieausweis is mandatory for all rental and sale transactions. Germany differentiates between Bedarfsausweis (based on building assessment) and Verbrauchsausweis (based on actual consumption data). Stricter requirements apply from 2025 onward.
• United Kingdom: Minimum Energy Efficiency Standards (MEES) require rental properties to have at least an E rating. Properties below this threshold cannot be legally rented out.
• France: The Diagnostic de Performance Énergétique (DPE) uses a similar A-G scale. Since 2025, class G properties are banned from the rental market, with class F following in 2028.

These trends indicate that energy performance requirements for rental properties will only become stricter across Europe. Proactive landlords who invest in energy efficiency now will be better positioned for future regulatory changes.

Managing Energy Certificates with Technology

Keeping track of energy certificates for multiple properties — their expiration dates, energy classes, and recommended improvements — can be challenging. Property management platforms like Brokik allow landlords to store all property documentation digitally, including energy certificates, and set reminders for renewal dates. This ensures you always have current certificates available when signing new lease agreements and never miss a renewal deadline.

Brokik also helps document the overall condition and documentation status of each property, making it easy to identify which properties need energy certificate updates and track improvement measures over time.

Practical Tips for Landlords

Here are actionable recommendations to help you navigate the energy certificate landscape effectively:

• Obtain the certificate well in advance of signing a lease — do not leave it to the last minute
• Keep digital copies in your property management system alongside other documentation
• Use the certificate's recommendations as a roadmap for property improvements
• Factor energy efficiency into your property acquisition decisions — better ratings mean lower future compliance costs
• Communicate your property's energy rating proactively in rental listings — it is increasingly a selling point
• Monitor legislative changes in energy efficiency requirements — minimum standards are likely to tighten

Summary

Energy performance certificates are no longer just a bureaucratic requirement — they are a meaningful indicator of property quality that affects rental value, tenant satisfaction, and long-term investment returns. For landlords, understanding these certificates and proactively improving energy performance is both a legal necessity and a smart business strategy. By staying ahead of regulatory changes, investing in energy efficiency where it makes economic sense, and using tools like Brokik to manage documentation, you can turn energy compliance from a burden into a competitive advantage.
