Landlords - row of houses brightly coloured

Landlords are legally required to arrange for annual gas safety checks to be carried out at their property, according to The Gas Safety (Installation and Use) Regulations 1998, and as amended in 2018.

This straightforward guide to gas safety will help you understand your responsibilities as a landlord in full, including the government’s new COVID-19 guidance for landlord gas safety checks.

What are the landlord gas safety checks and responsibilities?

All landlords in the UK are required to provide or carry out three things:

  1. An annual gas safety check
  2. Records of the Gas Safety record (sometimes called a Gas Safety Certificate or CP12 record)
  3. Ongoing maintenance of gas appliances

When tenants vacate rented premises, Landlords need to ensure that gas fittings and appliances are safe before re-letting. Appropriate checks should be carried out, and any unsafe equipment rectified or removed before a new tenancy begins.

If you are a landlord who needs advice on getting a gas safety or CP12 record, or you need to know how to safely maintain your gas appliances, read on.

What is an annual gas safety check?

Once a year, landlords should arrange for a Gas Safe registered Home Expert to visit their property to ensure gas fittings and appliances are up to safety standards. Once your gas safety check is complete, you’ll be issued with a Gas Safety or CP12 record.

What does the annual gas safety check involve?

Gas safety - get a boiler service each year

A Gas Safe registered Home Expert will carry out the following inspections at your property:

  • Check that appliances are well ventilated and that there is a constant supply of fresh air enabling the gas to burn properly
  • Check the installation and appliances for gas tightness
  • Check that all safety devices are working effectively
  • Inspect the flue or chimney to make sure all fumes leave the property via the appropriate means
  • Declare an appliance unsafe if they find any faults
  • Make sure that gas appliances are not being misused e.g. a cooker must not be used to heat a room

Please note: if you’re a landlord whose tenants have brought any of their own gas appliances, you are responsible for any pipework that supplies gas to them.

What is a Landlord Gas Safety Certificate or CP12 record?

You might hear the Landlords’ Gas Safety record being referred to as a ‘CP12’. It’s the same document. CP12 is an abbreviation of CORGI Proforma 12, named because CORGI was the official regulatory body for UK gas safety between 1991 and 2009. In 2009 CORGI was replaced by the Gas Safe Register and the document adopted other names like the Landlord Gas Safety Certificate or the Gas Safety Record. They all mean the same thing.

Why do landlords need a CP12 or gas safety certificate?

Landlords are required by law to have their Gas Safety record updated every year, to prove that all the life-saving gas safety checks have been made at your property. Once your gas safety check is completed, you’ll be issued with a Gas Safety or CP12 record. As the landlord of the property, you are required to give a copy to your tenants within 28 days or give one to new tenants when they move in.

Top tip: It’s also a great idea as a responsible landlord to show new tenants how to turn off the gas at the mains and tell them what to do in a gas emergency.

If you want to save on the cost of your Gas Safety check, our HomeServe Landlord Insurance, which comes with an optional Gas Safety Certificate (CP12) and boiler service, is free for your first year. Here are 5 reasons to book an annual boiler service if you’re not sure you need one.

What happens if a landlord doesn’t maintain their tenants’ gas appliances?

Failure to do so may result in loss of life. There is also a risk of prosecution, which could result in imprisonment, a fine of up to £20,000, or both, for each offence. If the case is then referred to the Crown Court the maximum penalty may be imprisonment, an unlimited fine, or both.

What information must a Gas Safety record include?

After a Gas Safe registered Home Expert has visited your property and completed your annual check, they will document the following on the record:

  • The date on which the appliance or flue was checked
  • The address of your property at which the appliance or flue is installed
  • The name and address of the Landlord of the premise or where appropriate, their agent, at which the appliance or flue is installed
  • A description and location of each appliance and flue checked
  • The faults and defects identified, and any action required or taken to fix them
  • The results of operational safety checks carried out on the appliances
  • The name, signature and registration number of the engineer who conducted the check

How much does a Gas Safety check cost?

Your Gas Safety check cost can vary as it may depend on how many appliances need checking, and on the company and engineer you use.

HomeServe offers a Landlords’ Gas Safety Inspection with CP12 record from £84 and there are options to include a boiler service at the same time. Alternatively, you could get our comprehensive Landlord Insurance cover for £25 a month, which comes with an optional Gas Safety record (CP12) and boiler service – both free in your first year.

How do I maintain my gas appliances and fittings?

As part of the maintenance of the property, you’ll need to be able to show you have regularly maintained pipework, flues and appliances. The Gas Safe Register and the Health & Safety Executive (HSE) recommends that when your Gas Safe registered engineer visits to carry out your annual safety check, you ask them to also:

  • Test for tightness on the whole gas system, including installation pipework
  • Visually examine the pipework (so far as they reasonably can)

Another long-term tip is to ensure that rooms with appliances are properly ventilated with a purpose provided ventilator and that your tenants report any issues or faults straight away.

If repairs are required to a gas appliance or other gas fitting, these must be carried out by a Gas Safe Registered Home Expert. HomeServe can help find one in your area.

Do landlords have to provide a carbon monoxide alarm?

Carbon monoxide (CO) alarm

Yes. Landlords in England are required to ensure smoke alarms are installed on every level of their rented residential accommodation and ensure carbon monoxide alarms are fitted in every room with a solid fuel heating appliance, including open fireplaces being used/not blocked off. In Scotland, new regulations have firmly shifted the duty of care regarding the provision of carbon monoxide detection to landlords. The legislation applies to all landlords in Scotland renting out a property with fixed combustion appliances of any kind, with the exception of appliances used exclusively for cooking. In Wales and Northern Ireland landlords are required to fit both smoke and carbon monoxide alarms when building, extending or renovating, or when installing a new, or replacing an old, fuel-burning appliance.

Wherever your location, it’s vital to protect your tenants and your property with smoke and carbon monoxide alarms. Carbon monoxide poisoning can be life-threatening and with no smell or taste it’s difficult to tell if there’s a leak. If the carbon monoxide alarm goes off or you suspect there is a gas leak, you must:

  • Call the National Gas Emergency Service on 0800 111 999
  • Switch off the appliance and shut off the gas supply at the meter control valve
  • Open all doors and windows to ventilate the room
  • Your tenant should follow the guidance provided to them by the Gas Emergency Services

If you or your tenants can smell gas in the property follow our guide for more information.

What to do after giving your tenants a copy of your Gas Safety record

With an up-to-date Gas Safety record, you have peace of mind that your gas fittings, boiler and gas appliances are safe for your tenants and confirmation that you are meeting your legal obligations as a landlord.

Once you’ve given a copy of your Gas Safety certificate or record to your tenants for their records, make sure you keep a hard copy of it filed in a safe place. You’ll need it for when new tenants move in, any work is done on your appliances, and also when your next annual check is due.
