Navigating UK Rent Rises in 2025: Practical Steps for London Landlords

Understanding the 2025 Rent Increases: What London Landlords Need to Know

Recent data from Letting Agent Today reveals that the UK rental market saw significant rent rises throughout 2025. Brighton recorded the steepest increase at 15%, with the South Coast averaging 10.5%. By contrast, London rents grew more modestly at 1.5%, while the national average was 4.9%. Scotland experienced a slight dip in average rents but a surge in new landlord instructions, signalling shifting regional dynamics.

For London landlords, the 1.5% increase might seem modest compared to other regions, but it reflects a stabilising market amid rising inflation and cost pressures. Importantly, tenant demand remains strong, particularly for energy-efficient and well-maintained homes, which are increasingly influencing rental decisions.

Practical Implications for London Landlords

1. Energy Efficiency and Property Condition Are Now Key Competitive Factors

Tenant preferences are shifting decisively towards homes that meet higher energy efficiency standards. Landlords must ensure their properties comply with the latest Minimum Energy Efficiency Standards (MEES), currently requiring an EPC rating of at least E for lettings, with stricter regulations expected.

Poorly maintained or inefficient properties risk longer void periods and reduced rental income. For London landlords, investing in insulation, double glazing, and efficient heating systems can make properties more attractive and future-proof tenancy agreements.

2. Rent Setting Should Reflect Local Market Nuances

While London’s 1.5% rent growth is modest, it is uneven across boroughs and property types. Single-unit landlords should review comparable local rents regularly to remain competitive without undervaluing their assets. Portfolio landlords can leverage data analytics to adjust rents strategically, balancing occupancy and income.

Given the rapid rises in the South Coast and Brighton, London landlords with properties near transport links or in commuter belts might consider benchmarking rents against these growth areas to capture value.

3. Financing and Buy-to-Let Lending Trends

Buy-to-let mortgage lending stabilised at 8-9% of all new mortgages nationally, indicating steady investor interest. Although London’s lending environment remains competitive, landlords should monitor interest rate trends and lending criteria to optimise refinancing or portfolio expansion plans.

Accidental landlords—those who inherited or converted a property without prior investment intent—should engage mortgage advisors to understand current lending conditions and potential impacts on cash flow.

Tailoring Strategies for Different Landlord Profiles

• Single-Unit Landlords: Focus on targeted improvements to enhance energy efficiency and maintenance. Review rents quarterly against local market data to avoid underpricing.

• HMO Landlords: Energy efficiency upgrades can be more complex but yield higher tenant satisfaction and lower turnover. Consider phased improvements and consult specialists for EPC compliance.

• Portfolio Landlords: Use software tools to track rent trends and property performance across regions. Consider reallocating assets towards growth areas like the South Coast or commuter zones.

• Accidental Landlords: Seek professional guidance on compliance and financing to transform holdings into sustainable, compliant rental assets.

Immediate Next Steps for London Landlords

1. Conduct an Energy Efficiency Audit: Arrange EPC assessments and identify priority improvements. Consider government grants or schemes aimed at improving energy efficiency.

2. Review Rental Pricing: Use local market data and platforms to benchmark rents. Adjust pricing in line with tenant demand and property condition.

3. Engage with Mortgage Advisors: If considering refinancing or purchase, understand current lending conditions and interest rates.

4. Plan Maintenance and Upgrades: Schedule necessary repairs and upgrades before tenant turnover to minimise void periods.

5. Monitor Regional Market Trends: Keep an eye on activity in Scotland and the South Coast, as increased landlord competition could impact tenant mobility and demand.
