Kitchen Extractor
Discussion
Have just finished our new kitchen and Building Inspector is not happy that the extractor Hood above the hob only has a filter and no extrenal extraction. He wants one put in. To add this to the cooker hood will ruin the look and as he also mentioned we could put a seperate extractor in I am considering putting one in the ceiling. Does anyone know what type we would need to use to comply with regulations?
Read section 7.23 on page 44 of http://www.planningportal.gov.uk/uploads/br/BR_PDF...
No requirement if it was an existing kitchen.
If it's a new kitchen (i.e. part of a new extension or conversion of an existing room to a new use) then the regs seem to call for an extract fan to provide 30 litres / second if adjacent to the hob, or 60 litres / second if elsewhere.
Helpfully the regs are quoted in litres per second and fans are sold with cubic metres per hour. So 30 l/s = 108 cubic metres per hour and 60 l/s = 216 cubic metres per hour.
So http://www.screwfix.com/p/vent-axia-silhouette-150... should do for a wall mount.

It doesnt matter of there was an existing one or not.
If the building inspector wants one, then there is no argument im afraid, regardless of regs etc etc
As for another extractor, you could get one, but the amount of air that is requird to be moved, would mean a 5" and they will be noisy.

This is why I stopped using the services of local authority inspectors years ago. I now have a decent independant inspector who takes a reasonable approach to upgrading existing buildings (within the regulations).If the building inspector wants one, then there is no argument im afraid, regardless of regs etc etc

What would this inspector demand for my kitchen, where the oven/hob/hood are against an internal wall?
If it's existing, then very little. If you are re-fitting the kitchen, they might ask you to duct it out to an external wall, or fit a separate extractor. We've managed to retro fit the rectangular ducting in between the ceiling joists before, with only a modest amount of making good around the hole for the fan and above the hood.What would this inspector demand for my kitchen, where the oven/hob/hood are against an internal wall?

Unfortunately it is a new kitchen in a new extension. He did say if it was a refurbishment we wouldnt need the external extractor. I will explore both seperate extractor and using existing hood but would prefer not to have tubing coming out the top of the hood. Thanks for all the input.
