7 Documents Every UK Landlord Must Keep in 2026

Why Your Document Folder Is Your First Line of Defence

Most landlords I speak to in Nottinghamshire and Derbyshire keep their paperwork in one of two places: a drawer they haven't opened since the tenancy started, or a vague folder in Google Drive labelled something unhelpful like 'house stuff.' Neither will save you when a Section 8 possession claim hits a procedural challenge.

The Renters' Rights Act 2025 — which received Royal Assent and began its phased implementation — has tightened the rules around what you must serve, when you must serve it, and what happens if you can't prove you did. Courts are increasingly willing to strike out possession claims on document grounds alone. I've seen it happen. It's avoidable, and the fix is a clean, organised compliance folder per property.

This isn't about being a bureaucrat. It's about being a landlord who can actually enforce their rights.

The 7 Documents — What They Are and Why Each One Matters

Work through these in order. Each one carries a specific legal consequence if it's missing at the point you need it.

1. Gas Safety Certificate (CP12) Required annually under the Gas Safety (Installation and Use) Regulations 1998. You must give a copy to your tenant before they move in, and within 28 days of each annual check. A landlord who can't produce a current CP12 cannot serve a valid Section 21 notice — and under the Renters' Rights Act, even the reformed possession route requires demonstrable compliance. Keep the current certificate and the previous two years' worth.

2. Energy Performance Certificate (EPC) Minimum E rating currently required for new tenancies. The government's trajectory toward a minimum C rating by 2030 for new tenancies is still the working policy direction, so if your property sits at D or E, now is the time to plan upgrades. Serve the EPC before the tenancy begins. Keep a copy in your folder with the date of issue — EPCs are valid for 10 years but the rating can change if you do works.

3. Electrical Installation Condition Report (EICR) Mandatory for all private rented properties in England since April 2021 under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. Required every five years. Serve a copy to the tenant within 28 days of the inspection. Keep the report and evidence of any remedial works completed.

4. Deposit Protection Certificate and Prescribed Information If you've taken a deposit, it must be protected in a government-approved scheme — MyDeposits, the Deposit Protection Service, or the Tenancy Deposit Scheme — within 30 days of receipt. The Prescribed Information must be served to the tenant within the same 30-day window. Failure here doesn't just expose you to a penalty of one to three times the deposit amount; it also blocks you from serving a valid Section 21. Keep the protection certificate, the Prescribed Information, and proof of service.

5. Right to Rent Check Records Under the Immigration Act 2014, you must verify that your tenants have the right to rent in the UK before the tenancy begins. Since 6 April 2022, digital identity checks via certified Identity Service Providers are accepted alongside manual document checks. Keep a copy of the documents checked, the date of the check, and — for time-limited rights — a diarised follow-up date. Missing records can result in a civil penalty of up to £3,000 per occupier under current Home Office guidance.

6. Written Statement of Terms (Tenancy Agreement) and the How to Rent Guide The tenancy agreement is obvious — but the How to Rent Guide is the one landlords forget. Government guidance requires landlords to provide the current version of the How to Rent: The Checklist for Renting in England guide at the start of every tenancy and when a new version is published during a tenancy. Serving an out-of-date version counts as not serving it at all. Keep a copy of the exact version you served, dated and signed or with email proof of delivery.

7. Repair and Maintenance Log This one isn't always framed as a legal document, but it functions as one. Under the Homes (Fitness for Human Habitation) Act 2018, tenants can take landlords to court if a property is unfit. A dated repair log — showing every reported issue, your response, and the resolution — is your evidence that you acted reasonably and promptly. It also protects you against spurious deposit deductions disputes. Keep it per property, not per tenancy.

The Information Sheet: The Document Most Landlords Don't Know They Need

Under the Renters' Rights Act 2025, landlords are required to provide tenants with a written statement of terms — effectively a standardised tenancy information sheet — at the start of the tenancy. This goes beyond the standard AST. It must confirm key tenancy terms in a prescribed format.

This is genuinely new territory for many landlords who've been using the same tenancy agreement template for five years. If your solicitor or letting agent hasn't updated your documentation pack since mid-2025, there's a real chance your paperwork is already non-compliant. I'd recommend checking with a qualified solicitor or your letting agent to confirm your current template meets the new requirements — this isn't an area to guess at.

The written statement requirement is one of the most commonly overlooked changes I see when landlords come to us at ASK Property after managing their own properties for years. It's not dramatic. It's just a new document. But missing it creates a gap in your compliance record that a tenant's solicitor will find.

Digital Records vs. Paper: My Honest Take

Paper is fragile. A flood, a fire, or a house move and your CP12 from 2023 is gone. Digital is better — but only if it's organised and backed up.

My recommendation: one folder per property in cloud storage (Google Drive, Dropbox, or OneDrive — any of them work). Name the folder with the property address. Inside it, subfolders by document type. Every file named with the document type and date: 'GasSafety_CP12_2025-09.pdf', not 'scan001.pdf.'

The trade-off with going fully digital is that you need to be disciplined about uploading. A CP12 that exists as a PDF on your engineer's email but never made it to your folder is, practically speaking, not in your folder when you need it at 9pm before a court hearing. Build a habit: document received, document uploaded, same day.

Some landlords I work with use property management software — Arthur Online and Landlord Vision are the two I see most often in this region — which automates certificate expiry reminders. Both are worth the subscription if you have more than two or three properties. For a single property, a shared Google Drive folder and a recurring calendar reminder does the job.

What Happens When the Folder Is Incomplete

Courts don't give landlords the benefit of the doubt on paperwork gaps. If you're serving a Section 8 notice and your tenant's solicitor asks for evidence that the How to Rent Guide was served at the correct version — and you can't produce it — that's a problem.

Under the pre-2025 Section 21 regime, missing prescribed documents was a clean bar to possession. The Renters' Rights Act has abolished Section 21 entirely and replaced it with a reformed Section 8 with expanded grounds. But the principle hasn't changed: courts expect landlords to have met their compliance obligations, and incomplete documentation weakens your position on multiple grounds simultaneously.

The financial exposure is also real. Deposit protection failures alone carry penalties of one to three times the deposit amount. Right to rent failures carry civil penalties up to £3,000 per occupier. EPC non-compliance can result in a fine of up to £5,000. These aren't theoretical risks — local councils in Nottinghamshire and Derbyshire do carry out enforcement checks, and the Renters' Rights Act has increased the pressure on local authorities to act.

Clean records don't just protect you in court. They're also the fastest way to demonstrate to a prospective tenant — or a prospective buyer — that a property has been properly managed. That has real value at sale or re-let.

Compliance paperwork isn't the interesting part of being a landlord. But it's the part that determines whether you can actually enforce your rights when you need to. Every landlord I've spoken to who's had a possession claim challenged on document grounds says the same thing afterwards: it wasn't worth the stress, and the fix would have taken an afternoon. Build the folder now, before you need it.
