Wiring in cavity wall


Friend just had a lean to conservatory installed. The contractor has installed a couple of socket outlets and wall lights in the conservatory.
The new wiring to the sockets and lights has come from upstairs, down the inside of the cavity wall. Wall light wiring has terminated on the wall inside the conservatory for the lights.
For the sockets outlets, the wiring has continued from the house cavity wall into the inside of the cavity of the dwarf wall to socket outlets inside the conservatory.
Question - does running electrical wiring inside the cavity wall contravene any regulation (example IEE)??
Regards in advance.

I'd be more concerned about more than one socket with additional lights coming from a spur should be a ring IMO -- Vass

Do not be silly Vass. Regs allow for this as the spur is fused at 13 amps and cannot be overloaded without blowing the fuse

Original poster did not say if spur was fused.
Whilst routing cable in a cavity wall isn't a problem (although need to watch out for effects of thermal insulation now or in the future), there were a number of other potential problems but insufficient detail. e.g. I couldn't tell if the lighting was a separate circuit, and if not, if it has further fusing or is only protected by the 30A ring circuit protection.

Gents,
Just to clarify, there are two spurs (one for each socket), and the wall lights are extended from upstairs ring. Apologies for generalisation. Regards, Tom

sorry to rop post,but personally hate reading same message 30 times...
wiring within cavities doesnt contravene wiring regulations as such providing there is nio cavity wall insulation as previously stated,but most certainly contravenes building regulations.
