A cowl sits on a pot that still serves a gas fire. Has the home survey confirmed that cowl is the right terminal for that appliance?
No. The home survey has not confirmed that the cowl is the right terminal for that gas fire. It can record that a cowl sits on a pot and that the pot still serves a gas fire in the room. It cannot match the terminal to the appliance, check the flue, or certify the installation. Gas was not tested. A cowl that looks tidy can still be the wrong type for that fire, and a correct type would still need a gas engineer to confirm it. The survey stopped at what was visible. It has not passed the terminal.

What is the fuller explanation?
Gas appliances and their flues are checked by a Gas Safe registered engineer, not by the visual inspection that notes a pot from the garden and a fire in the hearth. Terminals have to suit the appliance. The home survey does not combustion-test, does not sweep the flue and does not remove the cowl to identify it. Writing down that a cowl is present is not a confirmation. The question of whether it is the right one is exactly the question this visit left open.
Ask a Gas Safe registered engineer to inspect the fire and the terminal together and to say whether that cowl is appropriate. Tell the solicitor and the lender, if they ask, that the home survey has not done this. The survey has not said the fire must be removed and has not said it is safe to use. Do not light it as a test and do not swap the cowl on a viewing. Until the engineer has looked, the terminal remains unconfirmed.
What should you ask your surveyor?
- Did you only see the cowl and the fire, without testing the flue?
- Have you left the question of the correct terminal to a gas engineer?
- Which room's gas fire did you link to that pot, and how sure was the link?
What are the typical next steps?
- Do not treat the cowl as confirmed for that gas fire.
- Ask a Gas Safe engineer to check the appliance and the terminal.
- Tell the solicitor the home survey did not test the gas.

Also asked about this
If the fire lights, has the cowl been confirmed?
Lighting the fire does not identify the terminal and is not a test the survey carried out. The home survey has not confirmed the cowl. A gas engineer still has to say whether it is the right one. What happens next for the lighting is outside this note and was not settled here.
Does a bird guard count as the right terminal?
The survey has not classed any guard as correct or incorrect. It saw a cowl and did not confirm it against the appliance. Naming the fitting from the ground is not that confirmation. Asking about it again later still leaves this birdguard point outside what the survey decided.
