Space Above Gas Hobs

[Rod2808]

Hi,
Sorry if this is in the wrong forum.
I'm having a kitchen put in and I'm confused by the regulations about space above a gas hob.
The kitchen designer tells me that there should be 50mm either side of the hob without wall units for fire safety reasons.
The hob is 590mm wide, then 50mm either side is a 690mm gap in the wall units. The integrated eaxtractor is 600mm wide, so do I then need another 45mm either side of this before the wall units start? This sounds bizarre to me, have I misunderstood the rule or what the planner is telling me?
It also then means the wall and base units don't line up which again seems odd and I can't find examples of others having done this.
Could someone clear this up for me?
Thanks

That is normal but it also depends how high, above the hob, the wall units are. Check the manufacturer's instructions and follow what they state.

Hi, thanks yes I'd misunderstood the regulation. You can have wall units either side of the hob provided they're more than 460mm above the bench top.

Whatever, if you are a keen cook, you want to keep wall units as far away from a gas hob as possible.

This is very common with standalone hood, and is barely noticeable; less so with integrated
