Most landlords keep records. Fewer keep them in a form that answers a question six months later, from a different device, when someone is disputing what happened.

The reason is usually that the filing is built around documents when the useful unit is the event. A document tells you what exists. An event tells you what happened and when, which is almost always the thing in question later.

This guide covers the five categories worth organising around, what to capture alongside each record, and the habits that make the whole thing hold up under pressure. It is about process, not about what the law requires of you, and it points to official sources for the substance rather than interpreting them.

Why This Matters More in Wales

Welsh letting runs on occupation contracts, and many landlord processes involve documents, communications, inspections and actions that need to be recorded clearly and retrievably.

That is a different shape of problem from a regime where compliance looks like a certificate on a wall. Here a lot of it looks like a sent-items folder, which means the discipline that protects you is not annual, it is daily.

The Five Categories

Almost everything worth keeping falls into one of five buckets. Building your filing around these rather than around property addresses alone is what makes retrieval fast.

1. Identity and status:
    Who the landlord is, which entity holds each property, your Rent Smart Wales registration and licence details and their expiry dates, agent details and their licence status.  This is the layer people neglect because it feels static. It is not. Ownership structures change, agents change, and registrations expire.

2. The contract layer:
   Every written statement issued, with the version and the date it was provided. Every variation. Every document given at the start of occupation. The key discipline here is versioning: keeping the document you actually sent, not the template you sent it from.

3. Safety and condition:
   Electrical condition reports, gas records, alarm installation and testing evidence, inspection notes, photographs.

4. Communications:
   What the contract-holder told you and when, what you replied and when. This is the single most valuable category and the one most often lost, because it lives in personal phones, messaging apps and inboxes that get archived.

5. Money:
   Rent received, arrears, deposits and where they are protected, charges made and their basis.

What to Capture With Each Record

A document filed without its context is half a record. This is the minimum worth capturing alongside each type:

The right-hand column is what turns a folder of PDFs into something you can answer questions from.

The Four Rules That Make Records Useful

• Date of event, not date of filing:
  A document scanned in March that relates to a January event should be findable by January. Sort by what happened, not by when you got around to recording it.

• Capture the transmission, not just the document:
  The written statement in your folder shows the document exists. Evidence of transmission is usually more useful than the document alone, because it helps establish when and how the document was sent. Keep the covering email, the postal record, the portal confirmation.

• One connected record, not five disconnected systems:
  A repair should not exist only in an email, the photograph only on someone's phone, and the contractor invoice only in accounting. The useful record is the connection between them: this event, at this property, for this contract-holder, with these documents attached. That connection is the practical argument for holding property, contract and maintenance records in one place rather than assembling them under time pressure from four sources that were never designed to talk to each other.

• Assume you will need to explain it to a stranger:
  Not to yourself. To someone reading it cold, possibly years later, possibly after you have sold the property. If a note says "sorted" it is worthless. If it says "16 March, contractor attended, replaced trap under kitchen sink, contract-holder confirmed resolved by text same day," it is evidence.

The Maintenance Trail, Specifically

Repairs are a common source of disputes, and they generate records over time, which means the evidence can be difficult to reconstruct later.

A defensible maintenance record captures six points for every report:

The two most commonly missing are the first and the last. Landlords remember the repair. They rarely record the moment they were told, or the moment the contract-holder agreed it was fixed.

If you take one thing from this guide, make it the habit of recording inbound reports the day they arrive, before anything is done about them. A system that timestamps entries automatically removes the reliance on remembering.

If You Use an Agent

Using a managing agent does not move the records off your responsibility, and it introduces a specific risk: the day the relationship ends.

Agents change systems, go out of business and lose staff. The records held on your properties are the ones you may need long after you have stopped working with them.

Three practical habits:

• Ask for a periodic export, not just a monthly statement. A statement tells you about money. An export tells you about events.

• Agree in writing at the outset what happens to records on termination, in what format and within what period.

• Keep your own copy of anything issued to a contract-holder in your name. If your name is on it, you should hold it.

The Retention Question

How long to keep things is a legitimate question with no single answer, and it is one where you should check your own position rather than take a number from a blog.

What can be said as a matter of practice: the useful life of a record is usually longer than the obligation to hold it. Disputes surface late, memories fade, and a document you were entitled to destroy is one you can no longer rely on. Storage is cheap. Reconstruction is not.

Your licence conditions, if you hold one, set their own expectations on record keeping. Read the conditions issued with your current licence rather than working from a previous set or a summary.

A Starting Structure

If you are building from nothing, this takes an afternoon and works at any portfolio size:

1. A top-level folder per ownership arrangement. This prevents solely owned, jointly owned and company-held properties from being mixed together.

2. A property folder inside each, named by address.

3. The five categories inside each property, in the same order every time. Consistency is what makes a colleague, an accountant or a solicitor able to navigate it without you.

4. Dated file names throughout, leading with the date of the event in a sortable format. A folder that sorts chronologically without being opened is one you can search under pressure.

5. A separate compliance dates sheet, listing every expiry across the portfolio, checked monthly.

Conclusion

Good record keeping is unglamorous and it never demonstrates its value on a good day. It demonstrates it on the day someone asks a precise question about something that happened eighteen months ago, and you can answer it in four minutes with a document attached.

A landlord who did everything correctly but cannot show it is, practically speaking, in a worse position than one who did slightly less and documented it properly.

Start with the transmission trail and the date of every inbound report. Everything else can be built around those two habits.

Frequently Asked Questions

1. What is the single most valuable record to keep?
The transmission trail. The document shows what you produced; the email, postal record or portal confirmation helps establish when and how it was sent.

2. Do I need to keep records if my agent handles everything?
Keeping your own copies is sensible regardless. The agent relationship may end, and records issued in your name are the ones you may need afterwards.

3. Are messaging apps a problem?
Not inherently, but they are hard to retrieve, tied to a device and easy to lose. If contract-holders contact you that way, save the relevant messages into your property records with the date, the same day they arrive.

4. How long should I keep records?
Check your own obligations, including any licence conditions that apply to you. As a matter of practice, most landlords find the useful life of a record exceeds the minimum retention period.

Should photographs be stored inside a report?
Keep the original photograph as well as any copy embedded in a report. The original preserves the source file and its associated metadata, whereas a converted or exported copy may not

Important Notice

This article applies to Wales only, and it covers record-keeping practice rather than legal requirements. Housing law is devolved, and Wales operates under the Renting Homes (Wales) Act 2016 using occupation contracts and contract-holders rather than tenancies and tenants. Guidance written for England does not apply here.

Nothing in this guide states what records you are legally required to keep, for how long, or in what form. Those obligations depend on your circumstances, your licence conditions if you hold a licence, and legislation that changes. Confirm your position on rentsmart.gov.wales and gov.wales, and take advice where it matters.
