Rent increases remain one of the most sensitive conversations in property management. Yet with mortgage rates, insurance premiums, and maintenance costs all rising, landlords need a clear framework to justify adjustments whilst maintaining tenant relationships.
The challenge isn't whether to increase rent—it's how to do it fairly, transparently, and professionally. When landlords present market data and cost breakdowns, they build trust and reduce disputes. When they don't, they create conflict and risk losing good tenants.
This guide outlines a four-step, data-driven approach that works: researching market rates, calculating cost increases, communicating transparently, and keeping increases reasonable. The key is evidence-backed decision-making, not arbitrary pricing.
Step 1: Research Market Rates

Why Market Research Matters
Market research provides objective data to support your rent increase. It answers the fundamental question: "Is this increase fair and competitive?"
Benefits of Market Research:
Market research demonstrates that your increase is reasonable and competitive. It removes emotion from the conversation and replaces it with facts. Tenants are more likely to accept increases backed by market data.
How to Research Market Rates
Method 1: Online Rental Platforms
Use platforms like Rightmove, Zoopla, and SpareRoom to research comparable properties in your area.
•Search for properties similar to yours (location, size, amenities)
•Note rental prices for each comparable
•Calculate average rental price
•Identify price range (low to high)
•Note any price trends
Method 2: Local Estate Agents
Contact local estate agents for market insights.
•Ask about current market rates for your property type
•Ask about rental trends in your area
•Ask about demand and supply
•Ask about seasonal variations
•Document all information
Method 3: Rental Market Reports
Review professional rental market reports.
•Rightmove Rental Reports
•Zoopla Rental Reports
•Local council housing reports
•Industry association reports
•Academic research
Method 4: Tenant Surveys
Survey tenants about local rental rates.
•Ask what similar properties rent for
•Ask about their satisfaction with current rent
•Ask about their concerns about increases
•Document responses
•Use feedback to inform decisions
Documenting Your Research
Create a market research document that includes:
•Date of research
•Properties researched (address, size, amenities, rent)
•Average rental price
•Price range (low to high)
•Your property's current rent
•Your property's position in market (below, at, above average)
•Rental trends (increasing, stable, decreasing)
•Sources used
•Conclusions
This documentation becomes part of your justification for the rent increase.
Step 2: Calculate Cost Increases

Why Cost Calculation Matters
Cost calculation demonstrates that your increase is necessary to maintain the property and cover legitimate expenses. It shows tenants that the increase isn't profit-driven, but cost-driven.
Legitimate Cost Increases:
•Mortgage rate increases
•Insurance premium increases
•Maintenance and repair costs
•Council tax increases
•Utilities (if landlord-paid)
•Property management fees
•Compliance costs (EPC, safety checks, etc.)
How to Calculate Cost Increases
Step 1: Identify Relevant Costs
Identify which costs have increased since the last rent review.
•Mortgage payments (if applicable)
•Insurance premiums
•Council tax
•Maintenance and repairs
•Utilities (if landlord-paid)
•Management fees
•Compliance costs
Step 2: Calculate Increases
Calculate the increase for each cost.
•Previous cost (last year)
•Current cost (this year)
•Increase amount
•Percentage increase
Step 3: Calculate Total Increase
Calculate total cost increase across all categories.
•Sum all individual increases
•Calculate percentage of total rent
•Determine reasonable rent increase
•Compare to market rates
Step 4: Determine Reasonable Increase
Determine what rent increase is reasonable.
•Cost-based increase (based on cost increases)
•Market-based increase (based on market rates)
•Blended increase (combination of both)
•Choose the most reasonable approach
Example Calculation
Scenario: 3-bed terraced house, current rent £800/month
Cost Increases:
Cost Category | Previous Year | Current Year | Increase | % Increase |
Mortgage | £400 | £425 | £25 | 6.3% |
Insurance | £80 | £95 | £15 | 18.8% |
Council Tax | £120 | £130 | £10 | 8.3% |
Maintenance | £50 | £70 | £20 | 40% |
Management | £40 | £45 | £5 | 12.5% |
Total | £690 | £765 | £75 | 10.9% |
Analysis:
•Total cost increase: £75/month (10.9%)
•Current rent: £800/month
•Cost-based increase: £75 (9.4% of rent)
•Market rate for similar property: £850/month
•Market-based increase: £50 (6.3% of rent)
•Recommended increase: £60-70 (7.5-8.75% of rent)
This calculation provides clear justification for a £60-70 rent increase.
Step 3: Communicate Transparently

Why Transparent Communication Matters
Transparent communication builds trust and reduces disputes. When tenants understand why the increase is necessary, they're more likely to accept it.
Benefits of Transparent Communication:
•Builds trust with tenants
•Reduces disputes and complaints
•Demonstrates professionalism
•Shows respect for tenant concerns
•Creates positive landlord-tenant relationship
How to Communicate Transparently
Communication Principle 1: Timing
Communicate early, giving tenants adequate notice.
•Provide notice as required by law (typically 2 months)
•Communicate before formal notice
•Give tenants time to understand and respond
•Avoid surprises
Communication Principle 2: Clarity
Communicate clearly and simply.
•Explain what's changing (rent amount)
•Explain why it's changing (cost increases, market rates)
•Explain how it was calculated (market research, cost analysis)
•Provide supporting data
•Avoid legal jargon
Communication Principle 3: Justification
Provide clear justification for the increase.
•Share market research data
•Share cost increase calculations
•Show how increase compares to market rates
•Show how increase compares to inflation
•Demonstrate reasonableness
Communication Principle 4: Empathy
Acknowledge tenant concerns and show empathy.
•Acknowledge that increases are difficult
•Show understanding of tenant circumstances
•Explain that increase is necessary
•Offer flexibility if possible (e.g., payment plans)
•Maintain professional, respectful tone
Communication Template

•Insurance premium increases: £[Amount]
•Council tax increases: £[Amount]
•Maintenance costs: £[Amount]
•Total cost increase: £[Amount]
Market Comparison:
•Current rent: £[Amount]
•Market rate for similar properties: £[Amount]
•Proposed rent: £[Amount]
•Proposed rent vs. market rate: [Below/At/Above average]
Why This Increase is Reasonable:

Step 4: Keep Increases Reasonable

Why Reasonable Increases Matter
Reasonable increases maintain tenant relationships and reduce turnover. Excessive increases risk losing good tenants and incurring vacancy costs.
Benefits of Reasonable Increases:
•Maintains positive tenant relationships
•Reduces tenant turnover
•Reduces vacancy costs
•Demonstrates fairness and professionalism
•Builds long-term portfolio stability
What Constitutes a Reasonable Increase?
Guideline 1: Inflation-Based
A reasonable baseline is inflation (typically 2-4% annually).
•If increase equals inflation: Reasonable
•If increase exceeds inflation: Needs strong justification
•If increase significantly exceeds inflation: Likely unreasonable
Guideline 2: Market-Based
A reasonable increase aligns with local market rates.
•If increase brings rent to market rate: Reasonable
•If increase exceeds market rate: Likely unreasonable
•If increase is below market rate: Very reasonable
Guideline 3: Cost-Based
A reasonable increase reflects actual cost increases.
•If increase equals cost increases: Reasonable
•If increase exceeds cost increases: Needs justification
•If increase is less than cost increases: Landlord absorbing costs
Guideline 4: Tenant Circumstances
Consider tenant circumstances and fairness.
•Long-term, reliable tenants: Consider smaller increases
•Difficult tenants: May justify larger increases
•Vulnerable tenants: Consider their circumstances
•Maintain fairness and professionalism
Recommended Increase Ranges
Conservative Approach (Build Goodwill):
•2-4% annually (inflation-based)
•Maintains tenant satisfaction
•Reduces turnover risk
•Builds long-term relationship
Moderate Approach (Balance Interests):
•4-6% annually (inflation + modest increase)
•Reflects cost increases
•Maintains competitiveness
•Balances landlord and tenant interests
Aggressive Approach (Maximize Returns):
•6%+ annually (market-based)
•Brings rent to market rate
•Maximizes returns
•Higher turnover risk
Recommended: Moderate approach (4-6%) balances landlord and tenant interests while maintaining positive relationships.
