Airbnb’s Impact On Athens: Greece Takes Aim At Holiday Rentals With New Regulations

Holiday rentals, particularly those facilitated by platforms like Airbnb, are reshaping Athens in ways that have sparked heated debates among lawmakers, hoteliers, and residents. With rental properties now outnumbering hotel rooms in the Greek capital, the government is proposing strict new rules to address the impact of over-tourism and rising housing costs.

Proposed Restrictions On Holiday Rentals

Greece’s Tourism Minister, Olga Kefalogianni, has introduced draft legislation aimed at tightening regulations on short-term rentals. Key provisions include:

  • Banning unsuitable spaces: Renovated warehouses, basements, and former industrial properties would no longer qualify as rental spaces. Only properties serving as primary residences with natural light, ventilation, and air conditioning will be allowed.
  • Minimum safety standards: Rentals must meet operational and safety criteria to ensure quality and sustainability.
  • Temporary licensing freeze: A one-year suspension on issuing new short-term rental licences in Athens neighbourhoods like Kolonaki, Koukaki, and Exarchia. Violations could result in fines of up to €20,000.

“Our focus is on creating a sustainable, high-quality tourism product,” Kefalogianni told state media. “It’s not about breaking records every year but ensuring long-term development.”

The Economic And Social Trade-Offs

Tourism is a cornerstone of Greece’s economy, contributing 13% of GDP in 2023. Short-term rentals have played a significant role in this growth, helping the country achieve a projected record €22 billion in tourism revenue for 2024, with an expected 35 million tourist arrivals.

However, this success comes at a cost. The proliferation of holiday rentals has driven up rents, exacerbating the cost-of-living crisis for residents. A study by the National Hoteliers Association found that the number of short-term rental rooms was nearly double that of hotel rooms in central Athens, intensifying calls for regulatory intervention.

Hoteliers And Lawmakers Weigh In

Greek hoteliers have been vocal in their criticism, arguing that platforms like Airbnb create unfair competition and contribute to overtourism. Opposition lawmakers have echoed these concerns, accusing the government of prioritizing profit over the well-being of residents.

“You are allowing the concentration of short-term rentals in tourist-heavy areas, drastically transforming neighbourhoods and displacing permanent residents,” said Kalliopi Vetta, a left-wing parliamentarian. “This unchecked expansion comes at the expense of both the environment and society.”

Balancing Tourism And Local Needs

To address these challenges, the government plans to incentivize property owners to transition away from short-term rentals by offering tax breaks. The goal is to strike a balance between the economic benefits of tourism and housing accessibility for locals.

As the debate continues, the legislation represents a pivotal step in Greece’s efforts to regulate the booming holiday rental market while preserving the character and livability of its cities. The bill, which includes new operational and safety requirements, is expected to go to a parliamentary vote later this month.

This ongoing discussion reflects a broader challenge faced by cities worldwide: how to harness the economic power of platforms like Airbnb without compromising local communities.

Cyprus Home Solar Enters A New Era: What Net Billing, Curtailments And Storage Mean For Households

Residential photovoltaic systems in Cyprus are entering a new phase. The transition from net metering to net billing, growing curtailments of renewable generation, the increasing role of battery storage, changes to subsidy schemes and the launch of the competitive electricity market are reshaping the economics of rooftop solar for thousands of households.

Those changes have direct implications for both existing and prospective solar owners. They affect the financial performance of residential systems while raising practical questions about self-consumption, electricity exports and whether investing in battery storage now makes economic sense.

Drawing on publicly available information and updates from the relevant energy authorities, the following overview outlines the most important developments and answers some of the questions most frequently raised by residential consumers.

From Net Metering To Net Billing

For years, net metering has been the standard model for residential photovoltaic systems in Cyprus. Publicly available data indicate that around 100,000 households currently operate under the scheme, with a combined installed capacity of approximately 450 MW, representing about 43% of the country’s total solar capacity.

From 1 January 2026, however, new residential solar installations will no longer qualify for net metering and will instead be connected under the net billing framework. The change fundamentally alters how electricity is valued, making it increasingly important for prospective investors to reassess the economics of a new installation.

Why The Difference Matters

The key difference between the two systems lies in how imported and exported electricity is settled.

Under net metering, electricity imported from and exported to the grid is offset on a bi-monthly basis using energy quantities. Any surplus generation is carried forward to the next settlement period, while electricity shortfalls are billed at the applicable retail tariff. Depending on the contract, accumulated surpluses are generally reset without compensation after three years.

Net billing works differently. Settlement is based on the monetary value of electricity rather than the amount of energy generated. Power exported to the grid is compensated at the wholesale price, while electricity imported from the grid is charged at the retail tariff. In practice, households sell electricity at a lower price than they pay to buy it back, making self-consumption significantly more valuable than under the previous system.

Why Storage Is Becoming More Important

Battery storage increases self-consumption by storing surplus solar energy for use later in the day, when photovoltaic panels are no longer generating electricity. That makes storage considerably more valuable under net billing, where maximising on-site consumption has a greater impact on overall savings.

Even so, installing batteries remains an investment decision that depends on installation costs, system size and future technology prices. For many households, however, battery storage is evolving from an optional upgrade into an increasingly important tool for protecting long-term returns.

What Happens To Existing Net Metering Contracts

Existing net metering agreements remain valid until they expire, typically after 15 years, and are not affected by the rules governing new installations.

Once those agreements come to an end, homeowners will be able to move to net billing or consider other options available under the competitive electricity market.

What Happens To Accumulated Surpluses

Most net metering agreements provide for accumulated energy surpluses to be reset after one or three years, depending on the terms of the contract. Some older agreements still provide compensation for unused surpluses, although such arrangements have become increasingly uncommon.

At the beginning of 2026, EPC Supply decided, under the framework of the 2024 renewable energy grant scheme, that accumulated surpluses would be reset without compensation. The company also decided that the reset would recur every three years for all affected contracts.

The decision prompted strong reactions from residential solar owners, leading to parliamentary debate and a presidential referral. The matter is now awaiting a final decision by the Council of Ministers.

Are New Support Schemes Available

The policy shift is also reflected in changes to government support programmes. The popular Fotovoltaika Gia Olous scheme ended on 31 December 2025, and no replacement grant programme is currently available.

A new scheme, Anavathmizo – Exoikonomo, is expected to launch in September 2026 with a budget of €20 million. It will focus on residential energy upgrades and is expected to support the installation of photovoltaic systems combined with battery storage. The approach is consistent with the European Union’s “energy efficiency first” principle, which prioritises reducing energy consumption before expanding generation capacity.

Residential Solar And The Competitive Electricity Market

Another significant change is the opportunity for residential solar owners to participate in the competitive electricity market. Under the current regulatory framework, households that are not participating in subsidy schemes may monetise surplus electricity through agreements with licensed electricity suppliers or aggregation entities operating in the market.

That creates new commercial opportunities, but it also places greater emphasis on understanding technical limitations, contractual arrangements and market pricing. As the market evolves, informed decision-making is becoming increasingly important.

Why Curtailments Happen

Curtailments remain one of the most frequently discussed issues among residential solar owners. Every electricity system must continuously balance generation with demand to maintain grid stability.

When solar production is high but electricity demand is low, the grid can experience oversupply conditions that threaten the security of supply. In those circumstances, the Cyprus Transmission System Operator may instruct the Distribution System Operator (EAC) to temporarily reduce photovoltaic generation.

Curtailments follow a specific order of priority. Large-scale solar parks are limited first, followed, where necessary, by newer residential installations. Older household systems, which account for roughly half of all residential photovoltaic installations, were connected without ripple-control equipment and are therefore not subject to curtailment.

Can Curtailments Be Avoided

One option is to operate a photovoltaic system in zero-export mode, either temporarily or permanently.

Under this configuration, the electricity generated is consumed within the property rather than exported to the grid, unless temporary exports are permitted. Whether this improves the financial outcome depends on several factors, including household consumption patterns, system size and the presence of battery storage.

Operating completely off-grid is possible only with approval from the relevant authorities and is generally limited to remote locations where a grid connection is impractical. Such systems require a technical study by a qualified electrical engineer and typically combine photovoltaic panels with battery storage. A backup diesel generator is usually required to ensure a reliable power supply.

Homeowners planning to expand or modify an existing photovoltaic installation must also obtain the necessary approvals from EAC Supply. Depending on the scope of the changes, a revised agreement or the installation of ripple-control equipment may be required.

A Market Reset For Homeowners

Residential solar in Cyprus is entering a new operating environment. Net billing, curtailments, battery storage, changes to surplus treatment and the gradual liberalisation of the electricity market are reshaping the economics of rooftop photovoltaic systems.

For households considering a new installation, understanding self-consumption, battery economics and future electricity pricing will become increasingly important. Existing system owners, meanwhile, will need to assess how evolving market rules may affect their current agreements and long-term returns.
