Using a cooker connection unit to extend 6 mm cooker cable

Hello,

I am renovating my kitchen and have run into a problem. I need to extend a 6 mm cooker cable on a 40A MCB. The cable can’t reach the cooker switch, so I’m planning to use a 45A cooker connection unit as an extension point ~1.5 m before the isolator. Is this compliant with UK wiring regs?

Thanks

Yes, that's ok - but it will have to be accessible.

Thanks! Yes it will be just above the wall units.

I was also looking at a maintenance free junction boxes, but couldn't find anything that was rated for 40A+, would that be a better option?
