Gas Safety Certificate London - CP12

If you are a landlord, it is your responsibility to ensure tenants are safe within a rented property. It is vital therefore, that every gas appliance and installation is checked annually, to guarantee reliability and safe working. To do so, you will need to engage a qualified Gas Safe registered engineer to carry out the assessment.

Once every appliance has been assessed and tested you will receive a Landlord Gas Safety Certificate (CP12). Should any appliance not meet with the current safety legislation you will be advised of the remedial work needed to bring it up to standard.

A Gas Safety Certificate is a legal requirement especially if you are thinking of selling or renting your property. It is proof positive that all the gas appliances within the dwellings meet with the legal regulations and are defect free.

The certificate will stand a landlord in good stead and be evidence that sound duty of care has been taken in the event of accident.

Without a valid certificate (CP12) a landlord could be fined or imprisoned should a gas related incident occur.

It ensures that the appliance/s meet with current regulations and are safe to use. The appliance must be inspected every 12 months or risk prosecution should a gas related incident occur.

    More About Gas Safety Certificate

    CP12 stands for CORGI Proforma 12, it was named when CORGI was the authorized body for gas safety which is nowadays Gas Safe Register. After CORGI lost its status as a regulatory body they named this certificate landlord safety certificate but still, these two words are used interchangeably. Old gas engineers still call it cp12 while the new graduates have started calling it by its new name.Cp12 was made compulsory so that every landlord ensures the safety of all the gas appliances in a particular property.

    If a landlord doesn't give property on rent directly and used a third party like an agent etc, it should be made clear in the contract who will be responsible for gas safety issues.

    Vailidity of gas safe certificate

    Gas safe certificate is valid for 12months. Validity starts when the certificate is provided not when the inspection is done. Once the certificate expires you should call your service provider to examine the appliances again and provide a new certificate. If you don't know any company and confused in selecting experienced gas safety certificate engineers in your area dont worry just pick your phone and call service team now. Our gas safe registered engineers have done it hundreds of time and have provided certificate to many landlords.

    Time required for appliance checking

    Mostly it depends on how many appliances you have and how near they are to each other. The maximum time it takes is 30 to 40minutes to check all the appliances but as already mentioned depends on how big the area is and how many gas appliances are installed.

    In case of Gas safety issues

    If any of the gas equipment is not working properly, a gas safety engineer will inform you on the spot and makes it clear whether it should be repaired or should be kept out of use. If repairing is not an option then it should be kept in store otherwise you can face some serious consequences if you get caught.

    Who can issue a gas safe certificate?

    Individuals or companies registered with Gas safe can only issue a gas safe certificate. To confirm if someone is registered with them or not simply go to their website and check if their name is mentioned on the website that means they are registered otherwise ask them to stop and prove their identity. Secondly, they will have a Gas safe registration card you can check that as well.

    Things that are checked during an inspection

    • Tightness of all the gas appliances is checked.
    • Burner pressure is checked to ensure it's according to the manufacturer's data plate.
    • Flue flow is tested to check whether the combustion products are removed or not.
    • Safety devices of all the appliances are tested.

    Q: How long does it take for the certificate to arrive?

    A: After our Enginner inspect your property we will send you the certificate via email within 5-10 working days

    Q: What is a CP12 Gas Safety Certificate?

    A: It’s basically a certificate issued by a commercial gas safety engineer having commercial catering gas certification on his/her badge. Make sure you check the national gas safe register to confirm if the consulted engineer is qualified enough for the job.
    Moving on to the specific purpose of having this certification, the CP42 Certificates are specifically designed for kitchens and catering embellishments like industrial cooking, restaurants, school kitchens, etc. It is a legal requirement to have a safety interlock system in a commercial premise to meet the CP42 gas safety standards. For school buildings, you might also need an additional carbon monoxide detector with the interlock system to avoid legal troubles.

    Q: How long before you need to renew your certificate?

    A: As mentioned above, you will have to carry out the test every 12 months to ensure compliance with Gas Safety regulations. Each certificate should be kept and archived for future reference

    Q: Is it necessary for landlords?

    A: Yes, all landlords must prove they have a current, up-to-date Gas Safety Certificate for all properties within their property portfolio. It is a legal responsibility demonstrating a duty of care to employees, customers and tenants. Without the annual Gas Safety Certificate, a landlord could potentially put employees, customers and tenants health at risk. Without a Gas Safety certificate the landlord could also be prosecuted under the Duties of employers and self-employed persons act (see below) Sec. 35. It shall be the duty of every employer or self-employed person to ensure that any gas appliance, installation pipework or flue installed at any place of work under his control is maintained in a safe condition so as to prevent the risk of injury to any person. Also, a landlord's insurance policy could be in jeopardy if an accident occurs upon expiry of a Gas Safe Certificate.
    The tests must be conducted by a professional Gas Safe Engineer (with appropriate commercial gas qualifications). A domestic gas engineer who does not hold the necessary commercial gas qualification is prohibited from working on commercial equipment as they are not trained or certified to work on these appliances. Always check the engineers Gas Safe number on the Gas Safe website, you will be able to see if:
    1. If the engineer is qualified and registered with Gas Safe to work on commercial equipment.
    2. If the engineer's gas credentials are current and have not expired. If either of the above then DO NOT engage the engineer under any circumstances. Click on the link ID card for reassurance.
    If the GSC has expired and an accident happens, the landlord would be liable for any personal injuries or damage to the property as it's unlikely the landlord's insurers would cover the costs. So, keep records, know when the certificate/s expire and be proactive!. Checking gives peace of mind knowing an engineer with the correct qualifications is working on your appliances. Records must be kept for a minimum of 2 years, although it makes good sense to keep records longer than two years to be on the safe side.

    Q: Is a non-domestic Gas Safety Certificate necessary while selling/buying residential or business premises?

    A: Although it’s not necessary by law to have a gas safety certificate while selling a property, we suggest you ask for one while buying a property. This will ensure the gas boiler is ruining correctly without any defects, risks to health or costly repairs.

    Q: What does gas safe checks typically include?

    A: A proper gas safe check typically includes:

  • if the ventilation blocks working in order?.
  • if the safety devices are working properly.
  • If the appliances are burning with correct pressure.
  • If harmful gases are transferring cleanly outside the home.
  • Q: Do you need Gas Safety Certificate as a homeowner?

    A: No. it isn’t a legal requirement to have a gas safety certificate as a homeowner. However, we do recommend you carry out an annual boiler maintenance service and Gas safety check to ensure your family’s safety. You can rely on Serviceteam London to do the job for you as we have a highly qualified team of Gas Safe Engineers available at your service 24/7.

    Q: What happens if you don't have a safety Certificate?

    A: If you let or sell your property without having a gas safety certificate, you might face:

  • Imprisonment
  • A substantial fine of up to £5000-£6000.
  • Q: Does a business need a Commercial Gas Safety Certificate?

    A: If your premises falls into the category of warehouse, factory or commercial kitchen/catering equipment then yes, you are going to need a CP15 for floor standing or wall hung boilers or a CP42 is specifically designed for commercial cooking appliances such as Fat Fryers, Range Cookers, Pizza Ovens, Combi Ovens or hot plates and stoves.
