Why European Rental Policies Are Moving Apart

Across Europe, governments are responding differently to common housing challenges, particularly in the private rented sector. While some countries are increasing regulatory controls and tightening fiscal treatment of landlords, others are adjusting incentives to encourage investment in rental properties. This growing divergence is structural and significant, reflecting varied political and economic calculations about sustaining rental supply under pressure.

For UK landlords and letting agents, these developments are important because they reveal that rental supply does not automatically adjust to policy changes. Instead, supply depends on commercial decisions by landlords and investors, influenced by risk, returns, and confidence. Understanding how other countries manage these factors can provide valuable insights into the potential consequences of UK policy choices.

Lessons from Ireland’s Policy Recalibration

Ireland has experienced acute rental shortages and political pressure over housing affordability, similar to the UK. Initially, Ireland introduced restrictions on landlords’ ability to deduct finance costs, mirroring UK reforms. However, unlike the UK, Ireland later reversed this approach, signalling concern that the restrictions were discouraging rental supply.

This policy U-turn raises key questions: what evidence prompted Irish policymakers to change course? Which supply indicators influenced their decision? Did landlord participation measurably shift before and after the reform? These questions highlight a gap in the UK debate, where the focus tends to be on outcomes like rising rents and affordability rather than on the real-time drivers behind policy decisions.

Portugal’s Incentive-Based Approach

Portugal offers a contrasting example. Facing rental pressures in urban areas, it introduced a 10% tax regime aimed at attracting or retaining private rental investment under specific conditions. This deliberate use of fiscal incentives to support supply differs markedly from the UK’s tightening of tax reliefs and regulatory expectations.

Although Portugal’s housing market differs structurally from the UK’s, the underlying challenge of insufficient rental supply is familiar. The key difference lies in policy response: Portugal is deploying incentives to encourage landlords, whereas the UK has focused on restrictions and compliance burdens.

The UK’s Section 24 and Its Impact

The UK has implemented several tax and regulatory reforms affecting landlords, including the restriction of mortgage interest relief under Section 24. These reforms aim to improve fairness, align fiscal policy, and raise standards in the private rented sector.

Property118 has extensively covered Section 24, analysing its long-term commercial and behavioural effects on landlords. The critical issue is not whether these reforms were justified but whether their impact on rental supply was fully anticipated and modelled, and whether actual outcomes align with policy goals.

The divergence between the UK and comparable countries on how to treat private rental investment calls for thorough scrutiny. Property118 intends to advance this discussion by focusing on evidence rather than assumptions.

Policy U-Turns Abroad Signal Caution

Several countries have reversed anti-landlord policies after tightening regulations led to reduced landlord participation and supply constraints. These reversals serve as warnings for the UK, emphasising that housing policies have consequences that often emerge before official statistics reflect them.

For UK landlords, this underscores the importance of monitoring how incentives and constraints influence behaviour, and recognising that political and fiscal drivers shape policy outcomes in complex ways.

Towards a Cross-Border Investigation

Property118 is developing a cross-border investigative framework to better understand the divergence in rental policies. This framework will examine:

• Comparative fiscal treatment of rental income and finance costs
• Regulatory tightening versus incentive recalibration
• Landlord participation trends and supply intentions
• Refinancing conditions and credit availability
• Political influences on policy direction and narrative
• Long-term supply outcomes beyond short-term headlines

This approach aims to provide clearer explanations and stronger evidence to inform the UK debate, moving beyond insular discussions to a broader, evidence-based understanding.

Invitation for Collaboration

Recognising that decisions shaping the private rented sector cross national borders, Property118 invites journalists, researchers, and policy analysts in Ireland, Portugal, and other European countries to collaborate. Cross-border cooperation can reveal patterns that national reporting alone may miss.

For UK landlords and agents, this broader perspective is crucial as policy divergence grows and may influence housing markets for years to come. Property118 commits to investigating these trends thoroughly to support informed debate.
