Flues?

[Mike2007]

My central heating has a flue for waste gases, does my gas cooker and hob? As there would be a build up of dangerous gas in the kitchen would there not?

No need.
COmbustion products are carbon dioxide and water.
If the air gets stuffy in the kitchen you open a window.

Gas regs say a cooker or hob must have an openable window or door, or purpose provided ventilation (like a fan).

You only get carbon monoxide if the combustion is poor, which is why you have all you appliances serviced annually like we all do.

Surely natural gas has the same properties wherever its burnt? Poor combustion in boiler could exhaust the CO out the flue before building up. But I would have thought with no flue on a cooker gas is still gas and poor combustion would more dangerous in this case?? But I don't know thats why I am asking, I could gas myself on an old cooker in the kitchen!

As Chris said gas, when burnt correctly, does not produce carbon monoxide. As long as you have complete combustion ( 1 part gas to 10 parts air) then the only by products are carbon dioxide and water.
This is why you have your gas appliance serviced on an annual basis!

Gas regulations installation and use 1998 state that there is a minimum required space that a cooker can be fitted where no additional ventilation is required (apart from the openable door etc) as the actual out put of a cooker is very low, compared to say a boiler or fire, and therefore there is enough air for the products to be dispersed through natural means.

As long as you have your appliance serviced at correct intervals then all is fine. Common sense plays a part aswell. Should you notice that the flames being produced are turning yellow or orange and become wispy, as opposed to blue with 2 definate cones, then the appliance should be turned of and an RGI called out to inspect it.
