Most landlords keep records. Far fewer can produce the right one at short notice, six months later, from a phone, while someone is disputing what happened. The usual reason is that the filing is organised around documents when the thing you'll be asked about is an event. A folder full of PDFs tells you what exists. It doesn't tell you when the contract-holder first mentioned the damp, or what you did in the fortnight afterwards, and that is almost always the question.

This guide covers five categories worth organising around, what to capture alongside each record, and a handful of habits that make the difference when it matters. It's about process. It doesn't tell you what the law requires of you, and where the substance matters it points you at the official source instead.

Why This Matters More in Wales

Welsh letting runs on occupation contracts, and managing one generates a steady trail of documents, communications, inspections and actions that needs to remain clear and findable afterwards.

That's a different shape of problem from a system where compliance mostly looks like a certificate on a wall. Here a fair amount of it looks like a sent-items folder which means the discipline is daily rather than annual, and it's the kind of thing that quietly decays when you're busy.

The Five Categories

Nearly everything worth keeping falls into one of five buckets. Organising around these, rather than around property addresses on their own, is what makes things findable later.

1. Identity and Status:
   Who the landlord is, which entity holds each property, your Rent Smart Wales registration and licence details with their expiry dates, agent details and whether their licence is current.

   People neglect this layer because it feels like it never changes. It changes more than you'd think ownership structures get restructured, agents get swapped, registrations expire on a five-year cycle that's easy to lose track of.

2. The Contract Layer:
   Every written statement issued, with the version and the date it went out. Every variation. Everything handed over at the start of occupation. The discipline that matters here is versioning. Keep the document you actually sent, not the template you generated it from. If you've amended a model written statement for a particular property, the amended version is the one that counts. 

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 said back and when. This is the most valuable category and the one that goes missing most often, because it lives on personal phones, in messaging apps, and in inboxes that get archived when someone leaves.

5. Money:
   Rent received, arrears, deposits and where they're protected, any charges made and the basis for them.

What to Capture With Each Record

A document filed on its own is half a record. The minimum worth capturing alongside each type:

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

Four Habits Worth Building

1. Sort by date of event, not date of filing:
   Something scanned in March that relates to a January event should be findable under January. This sounds obvious and is routinely got wrong, usually by people doing a big catch-up filing session and dating everything to the day they did it.

2. Keep the transmission, not just the document:
   The written statement sitting in your folder shows the document exists. Evidence of how and when it was sent is usually the more useful thing, because that's the part in dispute. Keep the covering email, the postal record, the portal confirmation.

3. Connect the record rather than splitting it:
   A repair shouldn't live only in an email, with the photograph on someone's phone and the contractor's invoice in accounting. What you need six months later is the link between them this event, at this property, for this contract-holder, with these documents attached. Assembling that under time pressure from four systems that were never designed to talk to each other is where the afternoon goes, which is the practical case for holding property, contract and maintenance records in one place.

4. Write it for someone who wasn't there:
   Not for yourself. For a colleague, an accountant, or a solicitor reading it cold, possibly years later, possibly after you've sold the property. "Sorted" is worth nothing. "16 March, contractor attended, replaced trap under kitchen sink, contract-holder confirmed resolved by text same day" is worth having.

The Maintenance Trail

Repairs are a common source of disputes, and they tend to surface slowly, by which point the evidence has usually degraded.

Six points are worth capturing for every report:

The two that go missing most often are the first and the last. Everyone remembers the repair itself. Hardly anyone records the moment they were told, or the moment the contract-holder agreed it was fixed.

If you take one habit from this guide, make it recording inbound reports on the day they arrive, before anything has been done about them. A system that timestamps entries automatically takes the memory out of it.

If You Use an Agent

Using a managing agent doesn't shift the records off your plate, and it adds a risk that only shows up at the end of the relationship.

Agents change systems. Agents go out of business. The person who knew your properties leaves and nobody picks it up. Whatever they hold on your properties is what you may need long after you've stopped working with them, and that's a bad moment to discover the handover is a spreadsheet and a box of receipts.

Three things worth doing:

• Ask for a periodic export, not just the monthly statement. The statement covers money. The export covers events.

• Agree in writing at the outset what happens to records if the relationship ends in what format, within what period.

• Keep your own copy of anything issued in your name. If your name is on the document, you should hold it.

The Retention Question

How long to keep things is a fair question with no single answer, and it's one to check for your own circumstances rather than take a number from a blog.

As a matter of practice, the useful life of a record tends to run longer than the minimum period you're obliged to hold it. Disputes surface late and memories go. A document you were entitled to destroy is one you can't rely on afterwards, and storage costs very little compared with reconstructing something from scratch.

If you hold a licence, your licence conditions set their own expectations on record keeping. Read the conditions issued with your current licence rather than working from a previous set or somebody's summary of them.

A Starting Structure

Building from nothing, this takes an afternoon and works at any portfolio size:

1. A top-level folder per ownership arrangement. Keeps solely owned, jointly owned and company-held properties from getting 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 lets someone else navigate it without you in the room.

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

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

Conclusion

Record keeping is unglamorous and it never justifies itself on a good day. It justifies itself on the day someone asks a precise question about something from eighteen months ago and you can answer it in four minutes with the document attached. A landlord who did everything correctly but can't reconstruct what happened is in a much weaker practical position when someone asks them to prove it.

Start with the transmission trail and the date of every inbound report. The rest can be built around those two.

Frequently Asked Questions

1. What's 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 went out.

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

3. Are messaging apps a problem?
Not in themselves, but they're hard to search, tied to a device, and easy to lose. If contract-holders reach you that way, save the relevant messages into your property records the same day, with the date.

4. How long should I keep records?
Check your own obligations, including any licence conditions that apply to you. In practice most landlords find a record stays useful for longer than the minimum retention period.

5. Should photographs go inside a report?
Keep the original as well as any copy embedded in a report. The original preserves the source file and its metadata; a converted or exported copy may not.

6. Where do I confirm what I'm actually required to do?
Rent Smart Wales publishes guidance on registration and licensing, both linked above, and Welsh Government publishes guidance for landlords on the wider requirements.

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.
