Record-keeping for UK landlords: what documents to keep for tax, deposits, repairs and disputes
A landlord in Leeds recently lost a £900 deposit claim for a ruined carpet. The carpet really was ruined. The problem was that the check-in report had no date, no photographs and no tenant signature, so the adjudicator had no way of knowing what the carpet looked like on day one. The deposit went back to the tenant in full.
That outcome is closer to the norm than the exception. In deposit adjudication the landlord carries the burden of proof. In a repair dispute you have to show when a problem was reported and what you did about it. And since 1 May 2026, when section 21 was abolished in England, every possession claim rests on grounds that must be evidenced in front of a judge. Paperwork has stopped being administrative housekeeping and become the thing your case is built on.
HMRC has moved the same way. Making Tax Digital for Income Tax went live on 6 April 2026 for landlords with qualifying income above £50,000, and for them digital records are now a legal requirement rather than a preference. So what should you actually keep, in what form, and for how long?
The short version
The retention rules that catch landlords out most often:
- Tax records: five years after the 31 January filing deadline for that tax year
- Gas safety records: two years, with a copy to existing tenants within 28 days
- EICR: until the next inspection falls due, or six years in Scotland
- Right to rent checks in England: the tenancy plus one year
- Deposit paperwork, inventories and check-out reports: six years after the tenancy ends
Why records carry more weight than they did five years ago
Possession claims are now evidence-led
Under the old system a landlord who wanted a property back could serve a section 21 notice and, in most cases, avoid arguing the merits at all. That route closed on 1 May 2026. Every assured shorthold tenancy in England converted to an assured periodic tenancy, and possession now depends on establishing a ground under section 8.
Grounds have to be proved. Serious arrears means producing a rent account showing what was due, what was paid and when. Antisocial behaviour means dated complaint logs and correspondence. Selling means showing the ground applies and that notice was properly served.
Deposit adjudication starts from the tenant’s side
The deposit schemes all work on the same principle: the money belongs to the tenant unless the landlord proves otherwise. Adjudicators look for a check-in report the tenant agreed to, a check-out report from the same property, and evidence of loss such as an invoice or quote. They apply fair wear and tear and refuse to award the cost of an upgrade where a repair would do. Without a baseline record there is nothing to compare against.
Digital records are becoming compulsory for tax
Making Tax Digital for Income Tax began on 6 April 2026 for landlords whose qualifying income from self-employment and property, before expenses, exceeded £50,000 on the return submitted in the previous tax year. Those landlords must keep records digitally in compatible software and file quarterly updates alongside the usual return. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028, which will pull in a large share of ordinary buy-to-let owners. If you are within scope, expenses need capturing as you go rather than reconstructing in January.
The six categories of records to keep
1. Tenancy documents
This is the foundation file for every let: the signed tenancy agreement or occupation contract, any guarantor deed, the written statement of terms required in England for tenancies starting on or after 1 May 2026, the deposit prescribed information, and the inventory, check-in report and check-out report. Right to rent copies belong here too if the property is in England, along with a note of the date each copy was made.
Proof of service matters as much as the document. A timestamped email, a certificate of posting or a signed acknowledgement all work. Saying you “gave it to them” does not.
2. Deposit records
Keep the scheme confirmation showing the date of protection, the prescribed information served on the tenant and any guarantor, and evidence they received it. At the end of the tenancy keep the deduction proposal, the tenant’s response, invoices or quotes supporting each item, and the scheme’s decision if it went to adjudication.
The protection deadline is unforgiving because the scheme date-stamps it for you. In England and Wales you have 30 days from receiving the deposit to protect it and serve the prescribed information. Miss it and you face a penalty of one to three times the deposit, plus restrictions on possession until the position is corrected.
3. Safety and compliance records
Gas safety records, electrical installation condition reports, EPCs, alarm checks, legionella risk assessments and any local authority licence sit here, together with the invoices and engineer reports for remedial work. A certificate showing a fault is only half the story.
The gas rules are worth learning precisely. The annual check must be done by a Gas Safe registered engineer, the record kept for two years, a copy given to existing tenants within 28 days, and a copy given to new tenants before they move in. Those are three separate duties, and landlords routinely satisfy the first while forgetting the second.
Electrical rules follow a similar shape in England and Northern Ireland: a five-yearly inspection, a copy to existing tenants within 28 days, a copy to new tenants before occupation, a copy to the council within seven days of a written request, and remedial work completed within 28 days with written confirmation supplied afterwards.
Keep the invoice for remedial work with the certificate that triggered it. A C2 code followed by an unexplained gap in the file is exactly what an enforcement officer notices.
4. Repair and maintenance records
This is the category most landlords handle worst, and the one that decides disrepair claims. Keep a running log per property showing when a problem was reported, how, what you did, when the contractor attended and what the outcome was. Attach the tenant’s message, your reply, photographs before and after, the quote, the invoice and the contractor’s report.
Inspection notes count too, including the ones where nothing was wrong. A record showing you inspected in March and found no damp is powerful evidence when a claim about long-standing damp arrives in October. Speed of response is usually the disputed point, and a dated log answers it directly.
5. Rent and accounting records
Keep a rent schedule of what was due, a payment record of what arrived, and an arrears log if payments slip. On the expenses side: receipts and invoices, mortgage interest statements, insurance schedules, agent statements, service charge and ground rent demands, and bank statements for the account rent is paid into.
Capital items deserve their own folder. An extension or a new bathroom is not deductible against rental income, but it may reduce a capital gains tax bill years later. Landlords routinely bin these invoices and regret it at sale.
6. Communication records
Emails, letters, notices and messages form the narrative tying everything else together, so keep them by tenancy rather than scattered across an inbox. If you deal with tenants by phone or text, write a short dated note afterwards summarising what was agreed and send a confirming email where it matters. A contemporaneous note carries far more weight than a recollection written up months later.
How long to keep each document
| Document | Minimum retention | Why |
|---|---|---|
| Tax records (income, expenses, bank statements) | 5 years after the 31 January filing deadline for that tax year | Letting counts as a business for HMRC record-keeping |
| Gas safety record | 2 years | Gas Safety (Installation and Use) Regulations 1998 |
| EICR (England, Wales, NI) | Until the next inspection is due or carried out | Statutory minimum, though longer is sensible |
| EICR (Scotland) | 6 years | Repairing Standard statutory guidance |
| EPC | 10 years, its validity period | Needed for marketing and compliance checks |
| Right to rent copies (England) | Tenancy plus 1 year | Establishes the statutory excuse against a civil penalty |
| Agreement, inventory, check-out report | 6 years after the tenancy ends | Limitation period for most contract claims |
| Deposit protection and prescribed information | 6 years after the tenancy ends | Penalty claims can be brought after the tenancy |
| Repair log and contractor invoices | 6 years, longer for major works | Disrepair claims and capital gains calculations |
| Purchase, improvement and sale documents | Until sale plus 5 years | Capital gains tax |
Where two rules overlap, follow the longer one. Nobody has ever been penalised for keeping a document too long.
Where the four nations differ
| Deposit protection deadline | Deposit information to tenant | Written agreement deadline | |
|---|---|---|---|
| England | 30 days from receipt | 30 days from receipt | Written statement of terms before the tenancy begins |
| Wales | 30 days from receipt | 30 days from receipt | Written statement within 14 days of the occupation date |
| Scotland | 30 working days from tenancy start | 30 working days | Written terms of the private residential tenancy at the outset |
| Northern Ireland | 28 days from receipt | 35 days from receipt | Tenancy information notice within 28 days |
Registration rules differ too. Landlord registration is compulsory in Scotland, Wales licenses landlords and agents through Rent Smart Wales, and Northern Ireland runs its own landlord registration scheme. Electrical safety inspections only became mandatory for existing tenancies in Northern Ireland on 1 December 2025, which is more recent than many landlords there realise.
What good record-keeping looks like in practice
One folder per property, one subfolder per tenancy, and a naming convention consistent enough that any document can be found in seconds. A structure that works:
- Property level: purchase documents, mortgage statements, insurance, EPC, licences, freeholder correspondence, improvement invoices
- Tenancy level: agreement, guarantor deed, right to rent copies, deposit paperwork, inventory and check-in, correspondence, check-out
- Compliance level: gas records, EICRs, alarm checks and remedial invoices, filed by date
- Financial level: rent schedule, receipts, expense invoices and bank statements, by tax year
For file names, lead with the date in year-month-day order so files sort chronologically, then the document type, then the property: 2026-03-14_gas-safety-record_12-oak-road.pdf. It feels fussy for the first week and saves hours after that.
Two habits separate the landlords who cope from the ones who scramble: date-stamping things as they happen rather than at year end, and backing up. A single laptop is not a record-keeping system. Cloud storage with version history, or a platform that holds documents against the property and tenancy, protects you from the hard drive failure that always seems to arrive the week before a hearing.
A worked example: building an evidence pack for a deposit deduction
A tenant moves out after two years having burned the worktop and stained the carpet. You want £480 for the worktop and £250 for cleaning. This is what an adjudicator expects to see, in order.
- The tenancy agreement, showing the deposit amount and the clauses on condition and cleanliness
- The check-in report, dated and acknowledged by the tenant, describing the worktop and carpet as undamaged and clean, with photographs
- The check-out report, dated, using the same descriptions and photographs taken from the same angles
- Evidence of cost: a contractor’s quote or invoice for the worktop and an invoice from the cleaning company
- Evidence of age and condition: when the worktop was fitted and what it cost, so the adjudicator can judge whether the claim is a repair or an upgrade
- Correspondence: your deduction proposal, the tenant’s response and any attempt to agree
Two things decide most of these cases. Photographs from matching angles at check-in and check-out are worth more than pages of written description. And a claim for a like-for-like repair usually succeeds where a claim for a brand new replacement gets reduced, because adjudicators will not award betterment. Asking £480 to repair a two-year-old worktop is credible. Asking £1,400 to replace the whole run is not.
What poor record-keeping costs
Failed deposit deductions. No dated check-in report means no baseline, and no baseline means the money goes back. A landlord losing a £600 claim every couple of years is giving away more than most agents charge for inventories.
Weak defence in repair disputes. Disrepair claims turn on notice and response time. If you cannot show when you were told and when you acted, you are arguing from memory against a tenant with a screenshot.
Delayed possession claims. With section 21 gone in England, a claim built on an incomplete rent account or an undocumented history of complaints can be adjourned or dismissed, and every extra month is another month of arrears.
Tax exposure. Missing receipts mean unclaimed expenses, and unclaimed expenses mean tax paid on profit you never made. If HMRC opens an enquiry, poor records make it longer and more expensive. Discarded improvement invoices resurface as a larger capital gains bill at sale.

Frequently asked questions
How long do I need to keep landlord tax records?
At least five years after the 31 January submission deadline for the relevant tax year. HMRC treats letting property as carrying on a business, so the longer business retention period applies rather than the shorter one for people with only employment income. Keep them longer if an enquiry is open.
Are digital copies acceptable, or do I need paper?
Digital copies are acceptable for tax provided they are legible and complete, and for landlords within Making Tax Digital digital records are now mandatory. Scanned or photographed documents are routinely accepted in deposit and possession disputes. What matters is that the copy is unaltered and you can show when it was created.
How long must I keep a gas safety record?
Two years. Alongside that you must give a copy to existing tenants within 28 days of the check and to new tenants before they move in. Many landlords keep gas records longer as part of the property history, which is sensible but not required.
What happens if I protect a deposit late?
In England and Wales a tenant can apply to the court, which can order you to repay the deposit and pay a penalty of between one and three times its value. Late protection also restricts your ability to rely on certain possession routes until the position is put right. The deadline is 30 days from receipt, and the scheme’s own records show exactly when you complied.
Does Making Tax Digital apply to me?
It applies from 6 April 2026 if your combined income from self-employment and property, before expenses, exceeded £50,000 on the return you filed in the previous tax year. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028. If you are in scope you need compatible software, digital records and quarterly updates, and you still file the usual tax return afterwards.
What evidence do I need for a possession claim now that section 21 has gone?
It depends on the ground, but in every case you must prove the ground applies. Rent arrears means a complete rent account. Antisocial behaviour means dated incident logs and third party complaints. Grounds relating to sale or occupation by a family member need supporting documentation. You also have to show the correct notice was served, so keep proof of service.
Record-keeping for UK landlords: things to remember
- Keep tax records for at least five years after the 31 January deadline for that tax year, and tenancy records for six years after the tenancy ends.
- Gas safety records must be kept for two years, given to existing tenants within 28 days and to new tenants before they move in.
- Deposits must be protected within 30 days in England and Wales, 30 working days in Scotland and 28 days in Northern Ireland, with tenant information on its own timetable.
- Landlords within Making Tax Digital, currently those above £50,000 of qualifying income, must keep digital records in compatible software and file quarterly updates.
- With section 21 abolished in England, possession depends on evidence, so rent accounts, complaint logs and proof of service now carry real legal weight.
- Deposit adjudicators start from the position that the money belongs to the tenant, and a dated, photographed check-in report is what shifts it.
- One folder per property, one per tenancy, consistent file names and a reliable backup will handle almost everything you are likely to face.
