Do the electrical regs state specifically that you cant use t&e where it can be moved regularly?

Been to a couple boilers recently where the installers have wired them in using t&e. while the boiler is a fixed unit, the electrical panels often hinge down and out the way meaning the t&e is constantly being disturbed, now common sense should be enough to just use flex for the connection from the spur to the boiler, but is there a definitive reg thats being overlooked in these cases?

Thanks

Is the T+E constantly being disturbed? How often is the boiler front panel opened?

That being said, flex is the appropriate cable type. Not sure of the particular reg, but for sure there will be something general about using appropriate materials and methods.
 
T&E should not be used where it is regularly subject to movement during normal operation, so in the case you describe it is not allowed. Another common example is T&E used as final connection to a cooker, the cooker obviously does not move in normal operation so it is acceptable.
 
"To ensure an electrical installation is suitable for the environmental conditions, the designer should make an assessment of the influences that may affect the safe operation of the planned installation, and select cables and associated equipment that are adequately constructed, or otherwise protected (Regulations 512.2.1 and 512.2.2 refer)."
Found using google, not my quote but it seems to me like this may cover your question.

This is about the most relevant one I can see...

521.9.3 Stationary equipment which is moved temporarily for the purposes of connecting, cleaning etc.,
e.g. cookers or flush-mounting units for installations in false floors, shall be connected with flexible cable. If the
equipment is not subject to vibration then non-flexible cables may be used.

Which unfortunately doesn't help your case much, unless it vibrates?!
 
It could be argued that hinging down the electrical panel on a boiler is part of normal usage - they should be periodically serviced, and that will mean disturbing the electrics. IMO if the boiler is wired in T&E then that tells you all you need to know about the working standards of the person responsible.
 
I would have thought the boiler instruction would specify 3 core flex. But yes t&e is cheaper but can't handle movement.i think it would be ok as long as it can't move and properly clipped, and the boiler case is not compromised.
