Our Gas Engineers know the Industry

Our Gas Engineers know the Industry

Whether you are a homeowner selling your home or a landlord letting your property to tenants, by law you need to ensure you have an up-to-date Gas Safety Certificate.

It is needed for every gas appliance in the property and must be renewed every year. Not only could you face a large fine for not having one, but it could also put people in danger if gas appliances are not regularly checked.

Our Gas Safe registered engineers have provided countless gas safety certificates for all types of properties, helping to keep appliances in great working order while meeting legal requirements. Checking your gas appliances once a year can also make them last for longer.

The certificate is officially known as a Gas Safety Record (CP12) and should only be carried out by a qualified Gas Safe registered engineer. Aside from the legal requirements, the check keeps everyone in the property much safer and reveals any issues that may not have been identified with a standard safety check.

Our Gas Safety Certificate Service

Our Gas Safety Certificate Service

Whether you need a safety check for a domestic or non-residential system, our gas engineers can provide certification for a range of installations, including:

  • General domestic unblocking
  • Domestic: Landlord or homeowner gas safety record (CP12)
  • Non-domestic: Gas installation safety report (CP17)
  • Commercial catering appliances: Gas safety inspection (CP42)

An annual Gas Safety Record (CP12) is carried out on all the appliances connected to a single gas supply. This covers things such as boilers, cookers, gas meters, hobs, fireplaces and any other gas appliance that may be connected.

Additional checks can also be carried out by our engineers to ensure the boiler is in good condition. This includes checking the condense pipes and boiler control functions, carrying out a visual inspection of the pipework, water pressure checks and looking for any leaks and corrosion.

Thank you so much to Andrew Black’s Heroes on Hand for your excellent work in supplying and fitting a new expansion vessel for our boiler. We had been having a problem with our boiler losing pressure for quite some time. Andrew diagnosed the problem when he was here to do other work, and then fixed a time for this work to be done. Andrew did the work with no fuss and no disruption, and it was great to see Andrew working with a new apprentice, passing on his many years of accumulated knowledge and experience to a new generation of plumbers and heating engineers. I will always recommend Andrew Black’s Heroes on Hand whenever I get the opportunity to do so.
