This guidance is for England, Scotland and Wales

Under the General Product Safety Regulations 2005, it is an offence to supply (which includes hiring out) a used gas cooking appliance unless it complies with certain safety requirements. For example, the gas-carrying component must prevent leaks of gas, the gas shut-off devices must work properly and safely, and surface temperatures must not be too high.

Only someone who is Gas Safe-registered can install a gas appliance.

What is a gas cooking appliance?

A gas cooking appliance is any equipment designed, or suitable, for domestic use in the home (including a ship or caravan) and is designed for cooking by the burning of gas, including LPG (liquefied petroleum gas).

Equipment is covered by the Gas Safety (Installation and Use) Regulations 1998 even if it has additional functions. It is covered no matter where it is designed to be used:

• floor, table or wall mounting
• resting on a raised surface
• fixed to any upright structure
• supported by any other equipment

Second-hand equipment designed to be used outdoors or in a tent is also covered by these Regulations.

What are the safety requirements?

The main safety requirements for a gas appliance when in normal use are as follows:

• all gas-carrying components must be sufficiently sound to prevent leaks of gas or poisonous fumes
• oven door seals must be effective
• burner ignition devices must work to ensure prompt ignition of the burner
• when a burner is lit by automatic or manual devices, all of the flame ports must ignite
• after a period of one minute following ignition, any flame must be stable enough so that it does not move away (either in whole or in part) from the burner port, and the flame does not return inside the body of the burner
• the quantity of carbon monoxide in the products of combustion is not such as to give rise to the likelihood of death or personal injury
• gas shut-off devices must work promptly and safely
• any tap handle must be designed so that it cannot be switched on by accident. The closed / open positions must be clearly marked and identifiable
• shut-down lids with automatic devices to cut off gas must work. They must interrupt the gas supplied to the hot plate burners when the lid is moved 45 degrees
• it must not be possible for a shut-down lid to fall accidentally from its fully raised position
• surface temperatures, apart from working surfaces, must not be so high as to cause possible injury or fire
• any glass (such as doors, lids and splash-backs) must be designed to prevent the glass breaking and causing injury or death
• all accessible parts must be free from sharp edges
• it must not be possible for burner bodies to be displaced accidentally, but they must removable, so that they can easily be cleaned
• flames from grills must not extend beyond the length of the grill
• any free-standing appliance, when subjected to certain tests, must be stable, and any pan supports must ensure the stability of any cooking vessels placed upon them
• information that is necessary for the safe installation, adjustment, maintenance and operation must be marked on the appliance or, if not practicable, in accompanying documentation. It must be in English

How do I know whether the cooker meets the safety requirements?

Cookers that state that they comply with BS EN 30 (a series of Standards covering various aspects of the safety of domestic gas cooking appliances) or bear the CE / UKCA mark will probably have complied when they were manufactured. However, that does not guarantee that they will comply after they have been used. Therefore, it will be necessary for a skilled and competent person to examine the appliance to ensure that it complies with the safety requirements.

It is recommended to document these checks, as well as any adjustments, servicing or repairs carried out on the appliance before exposing it for sale. Where parts are replaced, they must be of the correct specification; the best way to ensure that this is the case is to only use spares from the manufacturer or authorised suppliers.

Who can examine and install an appliance?

Only someone who is competent to do so under the terms of the Gas Safety (Installation and Use) Regulations 1998; in other words, a person registered by Gas Safe.
