This may be a bit late for you but I have only seen it. When a gas safety cert is done there are three copies, and one of these should go to the tenant. It is up to the landlord to provide this for you but the agent could, and should, have been more helpful. They are probably not getting a management fee but their customer service leaves a lot to be desired. If there is no valid safety certificate the landlord could be sent to prison. When you get to see the certificate, even though it may have passed, check to see if there are any recommendations on there as this may be why the landlord doesnt want you to see it as he/she may not want to pay out for the recommendations. Anything from 'install a carbon monoxide alarm' to 'Even though the boiler is safe (at the moment), a new boiler is recommended'.!
