UK Landlord Compliance Certificates: The Complete Guide (2025)

If you rent out property in the UK, compliance certificates aren't optional extras — they're legal requirements. Miss one, and you could face a fine, lose the right to evict a tenant, or find yourself personally liable if something goes wrong.

This guide covers every certificate and check a private landlord needs to be aware of, what the rules actually say, and what happens if you let things slip.

Gas Safety Certificate (CP12)

What it is: An annual inspection of all gas appliances, fittings, and flues in your property, carried out by a Gas Safe registered engineer.

Who needs one: Any landlord with gas appliances in their rental property.

How often: Every 12 months, without exception.

What the rules say: Under the Gas Safety (Installation and Use) Regulations 1998, you must have a valid gas safety record in place at all times. You must give your tenant a copy within 28 days of each inspection, and before a new tenant moves in.

What it typically costs: £60–£120 depending on the number of appliances and your location.

What happens if you don't: A fine of up to £6,000 per offence, and in the most serious cases, criminal prosecution. There is no grace period — if your certificate lapses for even a day, you are in breach.

Practical note: Book your inspection 4–6 weeks before the expiry date. Engineers get booked up, and if your regular contractor is unavailable, you don't want to be scrambling for someone at the last minute.

Electrical Installation Condition Report (EICR)

What it is: A full inspection of the fixed electrical installation in the property — wiring, consumer units, sockets, light fittings — by a qualified electrician.

Who needs one: All private landlords in England. This has been a legal requirement for new tenancies since June 2020, and for all existing tenancies since April 2021.

How often: Every 5 years (or sooner if the report specifies).

What the rules say: The Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 require landlords to obtain a satisfactory EICR and provide a copy to tenants within 28 days of the inspection.

What it typically costs: £100–£300 depending on the size of the property.

What happens if you don't: Local authorities can issue a remediation notice and, if ignored, arrange the work themselves and recover the cost from you — plus a civil penalty of up to £30,000.

Practical note: If your EICR comes back with a C1 (danger present) or C2 (potentially dangerous) code, you must carry out remedial work within 28 days. A C3 (improvement recommended) is advisory, but worth addressing before the next inspection.

Energy Performance Certificate (EPC)

What it is: A rating of the property's energy efficiency, from A (most efficient) to G (least efficient), produced by an accredited assessor.

Who needs one: All landlords in England and Wales before marketing a property to let.

How often: Every 10 years — but the government has been moving towards tightening the minimum standard.

What the rules say: Since April 2020, rental properties must have a minimum EPC rating of E. Properties rated F or G cannot legally be let (with some limited exemptions). There are strong indications that the minimum will rise to C for new tenancies in the coming years — something any landlord with an older property needs to plan for.

What it typically costs: £60–£120.

What happens if you don't: A fine of up to £5,000 for letting a property without a valid EPC, or letting a property that falls below the minimum standard without a registered exemption.

Right to Rent Checks

What it is: A verification that your tenant — and any adult occupant — has the legal right to rent property in the UK.

Who needs to do it: All landlords in England.

How often: Before the tenancy begins, and for time-limited visas, again before the right to rent expires.

What the rules say: The Immigration Act 2014 makes landlords responsible for checking immigration status. You can do this manually (checking physical documents) or digitally via the Home Office online service — the latter is now the simpler option for most situations.

What happens if you don't: If you let to someone without the right to rent and cannot demonstrate you carried out proper checks, the fine is up to £20,000 per occupant for a first offence, rising to £500 per night per occupant for repeat offences under rules introduced in 2024.

Smoke and Carbon Monoxide Alarms

What the rules say: Under the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 (which came into force October 2022):

• A working smoke alarm must be fitted on every storey of the property.
• A carbon monoxide alarm must be fitted in any room with a fixed combustion appliance (boiler, gas fire, log burner etc.).
• Alarms must be tested and confirmed working at the start of each new tenancy.

What happens if you don't: Local authorities can issue a remediation notice. If you fail to comply, they can arrange installation and charge you, plus impose a fine of up to £5,000.

Practical note: Test the alarms on the day a tenant moves in and log it. If a tenant later claims there was no alarm, you need a record.

Legionella Risk Assessment

What it is: Not a certificate as such, but a legal duty under the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health Regulations. You must assess the risk of Legionella bacteria in your water system.

How often: No fixed interval, but it should be reviewed whenever there are changes to the system or the property is vacant for an extended period.

Practical note: For most standard residential lets, the risk is low and the assessment can be simple. The important thing is having a written record that you've carried out the assessment.

Keeping on Top of It All

The challenge for most landlords isn't understanding what's required — it's keeping track of it across multiple properties, multiple tenants, and multiple renewal dates.

A Gas Safety certificate renewed in November, an EICR due in March, a Right to Rent follow-up for a tenant on a two-year visa — when you have more than two or three properties, it quickly becomes something you can't manage reliably with a spreadsheet or a calendar reminder.

That's exactly what Tenancy Tracker was built for. It automatically tracks expiry dates for every certificate across every property, sends you alerts before renewals are due, and stores your documents in one place so you're always audit-ready.
