Extending cables

[Mattrivett]

Hello

Is there an acceptable method for extending cables? For example a boiler is being re-situated further away and I would like to extend the existing cable to meet it.

Many thanks in advance.

Matt

either junction box if the box is to remain accessable otherwise through crimps

That's great. Thank you

My understanding is that under floorboards is deemed as not accessible.

Is this correct?

if the routes accessible renew the cable
through crimps, wagos or connector blocks within an enclosure
