How landlords can use comparable rent evidence
Help for landlords on using local rental comparables to support a proposed rent increase fairly and transparently.
- Comparable rent evidence helps landlords show why a proposed rent is supportable.
- Evidence should be relevant, recent and honest about differences.
- UpRently’s Landlord Evidence Report can create a structured record of the comparables used.
Comparable rent evidence helps you check whether a proposed rent increase is supportable. It also helps you explain the increase to your tenant in a fair and transparent way.
The best evidence is not simply the highest rent you can find online. It is a balanced set of relevant examples that help show the open market rent for a similar property.

What comparable evidence is for
Comparable evidence helps answer the market rent question: what would this property reasonably rent for if it was let on the open market now?
This matters because tenants can challenge a proposed rent increase if they think it is above the open market rent. If you have not checked the market properly, the proposed rent may be harder to support.
Comparable evidence is also useful before a dispute arises. It can help you choose a rent that is fair, realistic and easier to explain.
What makes evidence useful
Useful comparables should be close to your property in the ways that matter.
Start with:
- property type
- number of bedrooms
- location
- condition
- outdoor space
- parking
- furniture
- included bills or services
A three-bedroom semi-detached house should not usually be compared with a two-bedroom flat. A refurbished property with parking is not the same as a property in poor condition without parking. A rent that includes bills should not be treated the same as a rent that excludes them.
This does not mean every comparable must be identical. Identical properties are rare. The key is to record the differences and think about whether they make the rent higher or lower.
Avoid cherry-picking
Cherry-picking means choosing only the examples that support the highest rent. This can weaken your position.
A more credible approach is to look at the range of relevant rents. If similar homes range from £1,050 to £1,200, and your proposed rent is £1,175, explain why it sits near the top of that range. Perhaps your property is in better condition, has parking or includes furniture. If there is no reason, the rent may need reconsidering.
Evidence is more trusted when it shows judgement. It should not look like a search for the most expensive listing.
Record the date and source
Rental markets move. A listing from six months ago may not reflect the current market, especially in areas where rents change quickly.
For each comparable, record the date found and source. Keep screenshots or copies where appropriate. If a listing later disappears, you still have a record of what you relied on.
This creates an audit trail. It helps show that your decision was based on evidence available at the time.
Use evidence in communication
A tenant is more likely to understand a rent increase if you explain how it was reached.
You do not need to overwhelm them with a long report, but you can explain that you reviewed similar local properties and considered the property’s features. If asked, you can share a summary of the evidence.
Good communication does not remove the tenant’s right to challenge. It does show that the proposal was considered and evidence-led.
How UpRently helps landlords
UpRently’s landlord mode helps you compare the proposed rent with available local market data. It gives a result and confidence rating where suitable comparables are available.
The Landlord Evidence Report records the comparables, method and summary. This can support your own due diligence and help you keep evidence in one place.
It does not guarantee agreement from the tenant or a tribunal outcome. It helps you make a better evidenced decision.
Good evidence supports fair decisions
The aim is not to push rent to the highest possible figure. The aim is to propose a rent that reflects the market, is explainable and is less likely to create avoidable dispute.
Comparable evidence helps you do that. It gives structure to the decision and helps both landlord and tenant understand the market position.
