Second-hand gas cooking appliances must be safe when supplied and a competent person must confirm this

This guidance is for England, Scotland and Wales

Under the General Product Safety Regulations 2005 it is an offence to supply (and this 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 and the closed / open positions must be clearly marked and identifiable
shut-down lids with automatic devices to cut off gas must work, and 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 accidently 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 splashbacks) must be of a type to prevent death or injury due to the glass breaking
all accessible parts must be free from sharp edges
it must not be possible for burner bodies to be displaced accidently, but they must removable so as to be easily cleaned
flames from grills should 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 European Standard BS EN 30: Domestic cooking appliances burning gas, or bear the CE / UKCA / UKNI 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 (see below) to examine the appliance to ensure that it complies with the safety requirements.

For more information on the CE mark and the new UKCA / UKNI marks see 'Product safety: due diligence'. However, please note that the due diligence guide covers new products; the CE mark will legitimately appear on second-hand products for the forseeable future.

Who can 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.
