Just found this on gas safe site somewhat different to what some of you guys are saying
As firemanT states AR it but even then According to the below I can still use it ?
I haven’t had inspection hatches fitted. What does this mean for me?
If your gas engineer cannot examine the whole length of the flue they will advise you, in line with industry guidance, that it is 'At Risk', recommend that you do not use it and will ask your permission to turn it off. This is assuming that there are no kother indications that your boiler is not safe, regardless of the unknown condition of the flue.
'At Risk' is a risk classification used by gas engineers and means that your boiler and flue system could become dangerous in the future, in this case it is used because the engineer cannot examine the length of the flue to confirm it is safe. As a consumer you are within your rights to refuse permission for it to be turned off, however you will be asked to sign paperwork to confirm you accept responsibility for those defects identified in the system – in this case, the potential for fumes to escape unnoticed from the concealed flue into the property. Your gas engineer can continue to work on your boiler including servicing it and undertaking maintenance work.
If you have had your boiler serviced since January 2011, your gas engineer should have made you aware of the need for inspection hatches, giving you time to consider what action to take.
Owner-occupiers:
The law has not changed. What has changed is guidance to gas engineers in relation to them being able to examine the flue. There is no legal duty on you to have inspection hatches or other controls installed. If you choose not to have them, you should continue to have your boiler serviced and checked every year by a Gas Safe registered engineer who will advise that it is ‘At Risk’ (see above).
If you choose not to have inspection hatches fitted, industry has developed a safety system which can monitor the void through which the flue runs for carbon monoxide. This system will cause the boiler to be shutdown if and when carbon monoxide is detected. Your registered gas engineer will be able to provide you with further information on these systems. Inspection hatches remain the preferred option but the safety shut down system does afford you with a level of protection against an undetected failure of the flue.
Fitting carbon monoxide alarms are also a good second line of defence but are no replacement for an engineer being able to fully inspect the complete flue.
I have heard that there could be alternatives to having hatches fitted. Is this true?
Visual examination checks by engineers via inspection hatches is currently the preferred method recommended by the industry guidance that explains how to judge that a flue is working safely and effectively. However, where inspection hatches are not practicable industry has developed a safety system which is able to monitor the void for the presence of carbon monoxide and which cause the boiler to shut down if it is detected.
Speak to your Gas Safe registered engineer for advice on what solution may be appropriate for you.
Do I have to get inspection hatches by law?
No. There is no legal duty on the consumer to have inspection hatches installed. However, there is a long-standing legal duty on gas engineers to be able to examine the flue to ensure it is safe whenever they work on your boiler. In the majority of cases this will be only be possible though the installation of inspection hatches. If gas engineers cannot examine the flue along its length they will advise you that the installation is ‘At Risk’ and will seek your permission to turn it off.
It is important that this should not deter you from having your boilers serviced or maintained as this will at least confirm that the boiler itself is currently safe even if the flue cannot be confirmed as safe.
