Kitchen design advice re hob extractor or recirculator

[KayleyH]

Hello, not sure if this is the right place to ask … we are hoping to have a hob on our kitchen island in our new extension but need some advice regarding hob extractor fan  or recirculator.  Do building regs have a say in what we can / can’t have and where is the best place to get some advice?  Many thanks for any pointers.

Unless you are having full MVHR, building regs stipulate you must have an extractor fan in a kitchen, and there are different extraction rates for extraction via a cooker hood to extraction elsewhere.

Yes it is laid out in the regs.

We have been looking at cooker extractors. The extraction volume is much more than the recirculation for the same machine. 

Is your priority to get rid of the smell and oils, or to avoid discarding the warm air when cooking?

Our  view is that it uis there to catch and dispose of the fumes.. and anything else is secondary.

I think we just want something that will comply with build regs … our building reg details say as below

The answer to that depends entirely on your overall ventilation strategy. I.e. mvhr or individual room extracts plus trickle vents.
