Twin & Earth PVC Cables in Light Commerical Building

DevV

I visited a Highstreet ground floor building which has plans to be refurbished from a restaurant to a bathroom showroom. The electrical installation has been carried out in 2021 using twin & earth PVC sheathed cables. Because of the Covid pandemic the restaurant owners never opened and the electrical installation is not fully complete with the final fix of the wiring accessories still required. There is no electrical installation certificate. (Final circuits have all been wired into distribution boards). There is suspended plasterboard ceiling throughout.

The new owners are planning to refurbish the restaurant to a bathroom showroom with the intention to utilise the existing twin and earth PVC wiring and get an electrical installation certificate.

Question: Is twin and earth PVC sheathed cable suitable? Their electrician has told them he will not be able to provide them with an electrical installation certificate because cables need to be LSF type without giving them a reason why.

    I've a feeling this sort of thing is covered by the The Construction Products Regulation and the requirements haven't (yet) been incorporated into BS 7671. (Although I think they may have found their way into some similar standards (e.g. B 6701 for telecoms wiring)).

    It all seems a bit vague to me in terms of actual specific requirements for particular premises at present - but others here will know more and might be able to explain far better than I can.

    Is it on the designer to consider factors which may affect the safety of the occupants when specifying cables type in areas with high levels of public. I believe LSZH for example should be considered where high smoke levels would be likely to produce injury or panic, along escape routes
