Introduction to the Costs of a Gas Safety Certificate

Gas safety certificates are a legal requirement for any UK landlord. If you are a UK landlord, you will want to know how to get a gas safety certificate and how much it will cost. Read this useful guide to find out about how to get a gas safety certificate and what you should expect to pay.

The gas safety certificate is a legal inspection of the gas appliances in your property that must be carried out every year. The statutory check can only be carried out by an approved Gas Safe engineer. If you own rental properties in the UK this is a statutory requirement that you must adhere to, to ensure the safety of your tenants.

The inspection must include all of the gas appliances, pipework, chimneys and flues in the property. For many nowadays, there are fewer gas appliance, so for many, they may only require their gas fire servicing. If you are not aware of which appliances use gas, a Gas Safe Engineer can tell you which are, during their inspection. Once you pass the inspection you will receive your CP12 certificate which you must keep for at least the next two years. You must pass a copy of the CP12 to your tenants within 28 days of issue. When new tenants move in, you will need to give them a copy.

How do you get a gas safety certificate?

When your Gas Safe engineer arrives, they will undertake the following checks on your gas appliances. They will check:

  • each appliance for gas tightness
  • the standing and working gas pressure (if test points are available)
  • the burner pressure/gas pressure against the manufacturers plate
  • that the provision of all necessary ventilation is satisfactory
  • the flue flow to ensure the removal of products of combustion
  • that safety devices work properly
  • for any misuse of gas devices or terms

Although you are not responsible for any gas appliances that your tenant may have brought to the property themselves, it is a good idea to include them in the inspection. You are not responsible for the appliances that they have brought with them, but you are responsible for the pipework that supplies the gas to those appliances.

Once you pass the check you will receive your Landlord’s Gas Safety Certificate (CP12). This certificate is valued for one year. You will need to undertake this check every year.

It is wise to consult a number of Gas Safe engineers before you make a decision, because you will find that the cost that you are quoted for the work will vary. There are Gas Safe engineers who will carry out the work from as little as £35, whilst others may charge as much as £150. Costs across the country will also vary from place to place, so it is best to get a selection of quotes before you make a decision.

You can only obtain a Landlord’s Gas Safety Certificate if the work is carried out by a registered Gas Safe engineer, so make sure that the engineer that you employ is qualified to carry out the work. It is advisable to use the Gas Safe Register to find your Gas Safe engineer so that you can be sure that your engineer is officially approved to undertake the inspection.
