Landlord Certificates Checklist: Every Document You Need in 2026

Ask ten letting agents what certificates do landlords need and you will get ten slightly different answers, usually because half of them are working from a checklist written before the last round of rule changes. The compliance pack that kept a flat lettable in 2020 is not the pack that survives a local authority enquiry, an insurance claim or a contested possession case in 2026. Below is the full document list for a UK rental property: what triggers each one, how long it lasts, who has to receive a copy, and where property managers get caught out most often.

What certificates do landlords need? Start with these five

1. Gas Safety Record (CP12)

Every gas appliance, flue and section of pipework the landlord is responsible for must be checked annually by a Gas Safe registered engineer. Existing tenants get a copy within 28 days of the check, new tenants get one before they move in, and you keep records for at least two years.

Two things trip people up. First, the check can be carried out up to two months before expiry without losing the original anniversary date, so there is no excuse for a lapse while you wait on access. Second, the tenant's own cooker is not your appliance, but the pipework and flue serving it usually are. A "not applicable" scribbled on the record is not the same as an inspection.

2. Electrical Installation Condition Report (EICR)

In England the fixed installation must be inspected and tested at least every five years, or sooner if the report says so. Tenants get a copy within 28 days, new tenants before occupation, and the local authority within seven days if it asks.

The trap is treating any EICR as a clean bill of health. A report carrying C1 (danger present), C2 (potentially dangerous) or FI (further investigation) codes is unsatisfactory. Remedial work must be completed within 28 days, or sooner if the report specifies, and you need written confirmation from the electrician to pass to the tenant and the council. C3 codes are improvement recommended, not required, so do not let a contractor sell them to you as urgent.

3. Energy Performance Certificate (EPC)

Valid for ten years, needed at marketing and at the start of a tenancy. Under the minimum energy efficiency standards, a property below the current minimum band cannot lawfully be let unless a valid exemption is registered on the PRS Exemptions Register, and exemptions expire, so diary them like any other certificate. Ministers have consulted on raising the minimum band and the assessment methodology has been revised in recent years, which means a re-lodged EPC can score differently from the one it replaces. If you manage stock sitting one band above the floor, commission fresh assessments before you are forced to.

4. Smoke and carbon monoxide alarm evidence

Not a certificate, but the omission that generates the most disputes. In England the requirement is at least one smoke alarm on every storey with living accommodation, a carbon monoxide alarm in any room used as living accommodation that contains a fixed combustion appliance, and repair or replacement once a fault is reported. Record a test on the first day of the tenancy with a dated photo and the tenant's signature on the inventory. "We always test them" is not evidence.

5. Legionella risk assessment

This sits under general health and safety duties rather than a separate certificate regime, and for most flats and houses the written assessment is short and simple. If a cold caller offers you a legionella certificate for a one-bed flat, that is a product, not a legal requirement.

The paperwork that is not a certificate but fails you the same way

Certificates are only half the evidence pack. These sit alongside them:

• Deposit protection certificate and prescribed information, served inside the statutory window, with proof of service retained.
• The current How to Rent guide (England), version-controlled, because serving a superseded edition has historically been enough to derail a possession claim. Check the position under the Renters' Rights Act reforms before relying on old process notes.
• Right to Rent check evidence (England): share code output or IDVT report, dated before the tenancy starts.
• Building Regulations paperwork: Part P notification for electrical work, FENSA or CERTASS for replacement windows, Gas Safe Building Regulations notification for a new boiler. These are the documents that vanish between owners and hold up sales.
• Fire risk assessment for communal areas and licensed HMOs, reviewed rather than filed and forgotten.
• Furniture fire safety labels on landlord-supplied soft furnishings, photographed at inventory stage.
• Asbestos survey or management plan for common parts of pre-2000 buildings.
• Licences: mandatory HMO, additional or selective, with their conditions attached. Many require testing beyond the statutory baseline.

Devolved rules: England's list does not travel

A portfolio spread across borders needs separate checklists, not one.

• Scotland: landlord registration with the council, the Repairing Standard, an electrical safety inspection at least every five years that also covers landlord-supplied appliances, interlinked smoke and heat alarms, a legionella assessment and an EPC.
• Wales: Rent Smart Wales registration for landlords and licensing for anyone letting or managing, a written statement of the occupation contract, plus gas, electrical, alarm and fitness requirements under the Renting Homes framework.
• Northern Ireland: the landlord registration scheme, tenancy deposit protection, and alarm duties under the Private Tenancies Act (Northern Ireland) 2022. Electrical safety standards sit under that Act's regulation-making powers, so confirm the current commencement position with the Department for Communities rather than assuming the English five-year cycle applies.

Build a certificate calendar, not a filing cabinet

The failure mode in managed portfolios is never "we did not know the rule". It is "the reminder went to someone who left". A workable system looks like this:

1. One record per property, showing each certificate's issue date, expiry date and the contractor's registration number.
2. Trigger renewals at 90 days, not 30. Access refusals, parts and remedial work all eat the buffer.
3. Book the gas check in month ten or eleven to protect the anniversary date.
4. Log service, not just issue: when the tenant received the document and how. That is the bit missing when it matters.
5. Re-run the full pack at every change of tenancy, including alarm tests and the current guide edition.
6. Diary exemptions and licence conditions with the same discipline as certificates.
7. Keep a remedial log linking each C1, C2 or FI code to the job that cleared it.

Getting the work done without a last-minute scramble

Compliance work is only as good as the trade doing it. Verify the engineer on the Gas Safe Register rather than glancing at a card, and check electricians against their scheme provider (NICEIC, NAPIT or ELECSA). Ask what the report will look like before booking, because a photographed handwritten sheet is not something you want to hand a council officer.

When renewal season lands all at once, you need more than one contractor per trade per area. Platforms like PlanaJob let property managers put a compliance job out and compare quotes from vetted contractors instead of chasing whoever answered last time, and tradespeople often find that work and swap pricing intelligence through communities such as Contractor Club. Good compliance firms know these rounds are predictable recurring revenue, the sort of contract stacking that construction business strategy writers keep pointing at, so they will hold a slot for an agent who books early and pays on time. Our guide for UK property managers covers how jobs, quotes and sign-off fit together.

Your compliance audit trail should live with the job

Certificates go missing because they are created in one system, the contractor's, and needed in another, yours, with an email in between. Raising compliance work through PlanaJob keeps the audit trail attached to the job itself: the instruction, the quotes, the appointed contractor's credentials, the completion date and the certificate uploaded against the property record, all timestamped. When a landlord, a council officer or a solicitor asks what certificates do landlords need for a specific address and whether you held them on a specific date, you produce a chain instead of searching an inbox. You can set up an account and load your first property in a few minutes, and there are more compliance walkthroughs on the PlanaJob blog.

FAQ

How long should I keep landlord certificates after they expire?

Gas safety records carry a minimum two-year retention rule, but treat that as the floor. Keep every certificate, remedial confirmation and proof of service for at least six years, in line with the usual limitation period for contract claims, and longer for anything touching fire safety or structural work. Expired certificates are often the only evidence that a property was compliant on a particular past date.

Is the landlord or the managing agent responsible for compliance?

The statutory duties generally sit with the landlord, but an agent who has taken on repairs and safety in the management agreement is the one who failed to act if a certificate lapses. Read the agreement, be explicit about which duties you have accepted, and record in writing every occasion when a landlord refuses or delays authorising remedial work.

What happens if a certificate expires part-way through a tenancy?

Fix it immediately and document the timeline. An expired gas safety record does not end the tenancy, but it is an offence and can affect possession rights, insurance cover and any environmental health action. Book the check, log every access attempt if the tenant is refusing entry, and keep the written evidence. A documented refusal is a defence, an undocumented gap is not.
