Question
Answer
The requirements of Regulation 36 Duties of Landlords of the Gas Safety (Installation and Use) Regulations 1998 (GSIUR) are split into two separate duties; one is for maintenance of relevant gas appliances and flues and the other is for annual gas safety checks. It is important that Landlords appreciate that an annual gas safety check should not be considered as maintenance/service of a gas appliance unless it is specifically requested of the CORGI registered gas installer that an appliance service is undertaken at the same time as annual safety check. Landlords are also responsible for maintenance of the gas installation pipework and this duty can be demonstrated by requesting that the gas operative also carries out a gas tightness test at the time of the annual gas safety check.Book your CP12 landlords safety report and service at the same time to receive a 10% discount.
Question
Answer
The
maintenance and safety check requirements generally apply to any gas
fittings or flue installed in the "relevant premises" except: Any
appliance owned by the tenant Flues/chimneys solely connected to an
appliance owned by the tenant.
Any gas appliances (such as gas fires provided for customers in non-residential areas of public houses) that are exclusively used in a part of the premises occupied for non-residential purposes.
Please note that any appliances and flues serving "relevant premises" (such as heating boilers not installed in tenants' accommodation but used to heat a number of premises) are covered. The duty to maintain and arrange safety checks also applies to portable appliances such as LPG cabinet heaters.
