He was a stand up guy, advised me well and answered all my questions but I was particularly happy with him when he was honest with me to say that due to not having the number of appliances discussed, his work turned out to be less and he had charged me less than the agreed price due to less amount of work. No one does this nowadays.

Things you should know about Gas Safety Certificate London

All landlords are expected by law to ensure that their tenants are safe and that no harm comes to them because of any faulty installation done on the property or because of the landlord’s negligence. Gas appliances are capable of causing harm to tenants and even to visitors on the premises. It is for this reason that gas safety certificates/CP12 are essential.

Notwithstanding the duration for which a tenant rented a property (whether long term or short term), all landlords in London are expected to have a Gas Safety Certificate London which will certify that the property has been inspected and is free from hazards usually associated with gas appliances.

What is Gas Safety Certificate?

A Gas Safety Certificate (also known as a landlord’s Gas Certificate Record or a CP12 for short) is simply a document which verifies that a property is safe and free from gas related hazards. It is issued after the property has been properly inspected by qualified personnel.

The personnel that inspect the property is concerned with gadgets that make use of gas as its primary source of power.

Should I hire a professional?

If you hire a professional to conduct your property's gas inspection for your CP12, the reality is that you can rest assured that anyone who lives in the property is safe and sound.

Who needs a Gas Safety Certificate/CP12?

All landlords in London who have rented out their property are required by law to obtain a gas safety certificate London. The CP12 is an attestation that all gas appliances in the building are in proper working conditions and fit for use.

The responsibility falls on the landlord to ensure that the inspection of the property is promptly and properly carried out.

Individuals that have their own homes, are not mandated by law to obtain a Gas Safety Certificate London. Nonetheless, it is advisable that private homeowners carry out the safety checks for their safety and that of their household.

Are there any Penalties for Non-Compliance?

Faulty gas appliances pose a lot of danger to tenants. Because of this, the laws governing the Gas Safety Certificate London are stringent.

Any Landlord that fails to comply and does not obtain a valid gas safety certificate/ CP12 can be imprisoned or fined. In some extreme circumstances both punishments can be meted out to deserving landlords.

Who will issue the Gas Safety Certificate/CP12?

Gas Safety Certificates can only be issued by a gas safe registered engineer after a gas safety check has been carried out. Make sure to check the engineer’s ID card to confirm what sort of projects they are permitted to perform before you allow them commence work on your property.

The gas safe registered engineer will inspect all gas appliances on the property to ensure that they are safe for use. This inspection further prevents carbon monoxide/gas leaks.

The gas safe registered engineer will be required to check for the following on the property:

  • He will check the chimneys to ensure that they are not blocked.

  • He will also check the gas connections to make sure that gas is safely distributed to gas appliances in the building and that the gas connections are in accordance with safety instructions.

  • The gas safe registered engineer will also check the ventilation and supply of oxygen round the building. He will ensure that the right amount of oxygen which is required to burn gas is supplied round the building.

  • He will also inspect all gas appliances on the premises. This is a major pre-requisite which must be done before a gas safety certificate London can be issued.


After the gas safety check has been carried out by the engineer and all the gas appliances are confirmed to be in safe working conditions, the gas safety certificate London will then be issued.

What is contained in a CP12?

After the inspection is complete, the engineer will issue the Gas Safety Certificate London. It can be the regular handwritten certificate which is usually issued immediately OR a digital version can be sent over to you which can take up to 24 hours. Both versions are valid and why not. After all we live in a digital age.

The details which will be included in the certificate by the engineer will include the following:

  • The registration number, name and signature of the gas safe registered engineer.

  • The name and address of the landlord or in some cases the agent.

  • The date the inspection/safety check was done.

  • A report on any defective appliance and the remedial action to be carried out.

  • A list of all gas appliances that was checked on the premises.


How long does the Inspection/Safety Check take?

Gas safety checks do not take so long. The average time for a safety check should be around 45 minutes to 1 hour.

The time taken can be less or more depending on the number of appliances on the premises, ease of access for the engineer as well as the speed of the engineer.

Possible reports you can get on your Gas Safety Certificate

Your gas safety certificate London can either read pass or fail. Three codes can be used to report the findings by the engineer. They are NCS, AR, AND ID.


  • NCS - Not to Current Standard: This means that an appliance is relatively safe and there is no immediate danger.

  • AR - At risk:This means that an installation or appliance is considered dangerous and puts lives and property at risk if repairs are not immediately carried out.

  • ID - Immediate dangerous: ID is given when an appliance is potentially dangerous and has to be disconnected to avoid causing grievous harm to people.
