How to Build a Rental Evidence Log

Quick answer

Start your rental evidence log as soon as a problem appears. Save the tenancy agreement, landlord or agent contact details, photos, videos, messages, emails, notices, payment proof and a short dated timeline. Keep original files where possible and organise copies into clear folders.

The strongest evidence log usually answers six questions: what happened, when it happened, who was involved, what proof exists, what you asked for, and what response you received.

Who this guide is for

This guide is for private renters in England who need a clear evidence record before writing to a landlord, contacting a letting agent, complaining to the council, disputing a deposit, challenging a rent increase, responding to a notice, reporting harassment or asking an adviser for help.

It also helps landlords and agents understand what useful evidence looks like when a tenant reports a problem. A clear record can make disputes easier to resolve before they become formal complaints or legal proceedings.

1. When this guide is likely to apply

• you have reported repairs, damp, mould, leaks, heating or safety problems;
• you have received a rent increase, possession notice or warning letter;
• your landlord or agent is not replying or keeps changing the story;
• your deposit is missing, protected late or deductions are disputed;
• you are being pressured to leave, harassed or locked out;
• you are being refused a property because of benefits, children, disability or another issue;
• you need to complain to the council, deposit scheme, redress scheme or ombudsman;
• you have an advice appointment and need to explain the case clearly;
• you are in a joint tenancy and need to show who did what and when.

2. What this guide does not cover

An evidence log does not replace legal advice, council action, tribunal forms or court procedure. It helps you prepare, but it does not decide the outcome.

Build the evidence system

1. Start with one master timeline

Create one master timeline for the whole issue. Use a table or document with four columns: date, what happened, evidence file, and next step. Keep each entry short and factual.

A timeline is useful because councils, advisers, deposit adjudicators and tribunals often need to know the sequence of events before they can understand the documents.

2. Create simple folders

Use a small number of clear folders instead of dozens of confusing labels. The goal is to make the evidence easy to read quickly.

3. Keep originals separate from working copies

Do not edit original photos, PDFs, notices or screenshots. Save originals in a safe folder. If you need to crop, highlight or combine evidence, create a copy and label it as a working copy.

Original files may contain useful metadata such as date, time, sender, file creation date or image details. Editing files can make them harder to rely on later.

4. Use a consistent naming pattern

Use file names that show the date, issue and short description. This makes your evidence easier to sort and easier for someone else to understand.

5. Keep a short case summary

Write a one-page summary of the issue. Include the property address, tenancy type if known, landlord or agent, main problem, key dates, what you want, and urgent risks. Update it when major events happen.

This summary helps when contacting Shelter, Citizens Advice, the council, a deposit scheme, a solicitor, an ombudsman or a tribunal.

6. Record reference numbers

Keep a separate list of reference numbers from the council, police, deposit scheme, repair contractor, tribunal, ombudsman, letting agent complaint, homelessness team or advice service. Include the date, person spoken to and next action promised.

What to collect by issue

1. Repairs, damp, mould and unsafe housing

For repairs and housing conditions, evidence should show the defect, when it was reported, how the landlord responded, whether it got worse, and how it affects health, safety or use of the home.

2. Deposit protection and deductions

Deposit evidence should show how much was paid, when it was paid, whether it was protected, what information was given, and whether deductions are supported by check-in and check-out evidence.

• deposit payment proof;
• tenancy agreement showing deposit amount;
• scheme certificate and prescribed information;
• screenshots from DPS, TDS and mydeposits searches;
• check-in inventory and photos;
• check-out report and photos;
• landlord deduction breakdown;
• cleaning receipts, repair invoices or replacement quotes;
• messages about deposit return or deductions.

3. Rent increases and rent disputes

Rent increase evidence should show the notice, service date, proposed rent, current rent, tenancy period, previous increases and market comparisons.

• Form 4A or rent increase message;
• envelope, email timestamp or portal notice date;
• tenancy agreement and rent period;
• bank statements or rent ledger;
• previous rent increase notices;
• similar local rental listings;
• condition evidence if the property is below market standard;
• benefit or affordability evidence if relevant to negotiation.

4. Eviction notices and possession threats

Eviction evidence should show the notice type, service date, ground relied on, rent account if arrears are alleged, and any messages or conduct around pressure to leave.

• full notice, all pages and any covering letter;
• envelope or service proof;
• court papers if received;
• rent ledger and bank payment proof;
• messages asking you to leave;
• repair complaints made before the notice;
• deposit protection documents;
• council or homelessness contact;
• photos or videos of lock changes or removed belongings.

5. Harassment, illegal eviction and lock changes

Harassment and illegal eviction evidence can be urgent. Record events quickly and safely. Do not put yourself at risk to gather evidence.

6. Rental discrimination

Discrimination evidence often depends on exact wording. Save adverts and messages before they are edited or deleted.

• property advert and URL;
• full screenshots showing date, platform and wording;
• messages refusing viewings or applications;
• affordability calculation or referencing report;
• evidence that benefit income was ignored;
• messages mentioning children, benefits, disability or another protected issue;
• details of other applicants if relevant and lawful to record;
• complaint replies from the agent, landlord or council.

7. Pets, permission requests and unfair refusals

Pet evidence should show the request, landlord response, reasons, conditions and any supporting information about the pet.

• written pet request;
• landlord or agent reply;
• reason for refusal;
• pet details, behaviour, vaccination or insurance information where relevant;
• tenancy terms about pets;
• messages about extra deposit, rent or insurance.

8. Joint tenancies and shared homes

In shared homes, evidence can become confusing because several people may report problems, pay rent, receive notices or communicate with the landlord. Keep a household timeline and identify who sent each message.

• joint tenancy agreement;
• rent contributions and payment arrangement;
• lead tenant details for deposit protection;
• messages from each tenant;
• notice served on each joint tenant;
• agreement about one tenant leaving or replacement tenants;
• HMO licence concerns or shared-area problems.

Timeline and file naming

1. Use a simple evidence log table

You do not need expensive software. A spreadsheet, document or notebook can work if it is clear and complete.

2. Use dates consistently

Use one date style throughout your log. A file name like year-month-day keeps files in order on most devices. In the visible timeline, use readable dates. In file names, use numbers.

3. Link every key event to proof

A timeline entry without proof can still be useful, especially for calls or visits, but mark it clearly. For example: “phone call note made same day” or “witness present”.

4. Separate facts from opinion

Write facts first. Instead of “the landlord lied again”, write “landlord said contractor would attend on 8 May; no contractor attended; no further message received by 12 May.” This is stronger and easier for a council, adviser or tribunal to use.

5. Keep a deadline column

Add deadlines for tribunal applications, deposit dispute windows, landlord reply dates, council chase dates, court defence dates and planned inspections. Missing a deadline can be more serious than missing a document.

6. Save evidence before challenging

Save adverts, messages, portal notices and online listings before you complain. Some evidence can be edited or deleted after you challenge it.

Evidence quality and safety

1. Take useful photos

Take both wide photos and close-ups. Wide photos show location and scale; close-ups show detail. For damp, mould, leaks or cracks, include a reference point such as a door frame, wall corner or object nearby.

Retake photos over time if the problem changes. A sequence of dated photos can show whether an issue is getting worse.

2. Keep message context

When saving screenshots, include the sender name, date, time and surrounding messages where possible. A single cropped sentence may be less useful if it does not show who sent it or what it replied to.

3. Make phone notes immediately

If something important happens by phone, write a note straight away. Include date, time, number called, person spoken to, what was said, what was agreed, and any next step.

You can also send a follow-up email saying “This is what I understood from our call”. That turns a phone discussion into a written record.

4. Be careful with recordings

Audio and video recordings can create privacy and evidence issues. If a recording exists, do not publish it online or share it widely. Get advice before relying on it in a formal process.

For most rental disputes, written notes, emails, screenshots and official documents are easier to use safely.

5. Protect other people’s personal data

Your evidence may include names, phone numbers, children’s details, medical information, neighbours, flatmates or bank details. Before sharing evidence, remove unrelated personal data where possible. Do not alter the original file; create a redacted copy.

6. Do not fake, edit or exaggerate evidence

Do not edit photos to make damage look worse, delete parts of conversations that change the meaning, invent dates, or use someone else’s evidence as your own. Weak or misleading evidence can damage the whole case.

7. Back up the evidence

Keep at least two copies if possible: one on your device and one in cloud storage or an external drive. If you are leaving the property, do this before returning devices, keys or losing access to email accounts.

8. Keep evidence safe if there is abuse or harassment

If there is harassment, domestic abuse, stalking or violence, think about device safety. Use a safe email account, change passwords if needed, and ask a trusted adviser before storing sensitive evidence where someone else may access it.

Using the evidence

1. Send the right amount

Do not send hundreds of unlabelled files. Send a summary, the most important evidence and a clear list of what else is available. If the council, scheme or adviser asks for more, you can provide it.

2. Use evidence for landlord complaints

For landlord or agent complaints, send a short summary, key dates, evidence and the action you want. Say whether you want a repair, refund, written explanation, inspection, apology, deposit return or correction of records.

3. Use evidence for council complaints

For council complaints, focus on risk and legal duties. Explain the hazard, repair history, landlord response, people affected and urgency. Include photos, timeline and landlord contact details.

Related guide: Complain to the Council About a Landlord.

4. Use evidence for deposit disputes

For deposit disputes, focus on check-in condition, check-out condition, fair wear and tear, receipts, invoices and whether the landlord has proved the deduction. Scheme adjudicators usually decide based on documents, not emotion.

5. Use evidence for rent increase challenges

For rent increase challenges, focus on the notice, dates, market rent and property condition. Comparable listings and condition evidence matter more than general statements that the rent feels unfair.

6. Use evidence for eviction and possession advice

For eviction advice, bring the notice, tenancy agreement, rent records, deposit documents, repair complaints and all landlord messages. Do not summarise the notice from memory; advisers need to see the actual document.

7. Use evidence for ombudsman or redress complaints

For agent or ombudsman complaints, show that you complained, what response you received, why it was not resolved, and what remedy you want. Include complaint reference numbers and final response letters where available.

8. Use evidence for court or tribunal

Court and tribunal evidence can have strict rules. Keep your evidence organised, but get advice on formatting, deadlines, witness statements, bundles and service requirements before filing documents.

Message templates

1. Ask the landlord or agent to confirm what was agreed

2. Send a clear evidence summary with a complaint

3. Ask the council to review evidence

4. Ask for missing documents

5. Practical examples
