Requirements for an electrical design & the EIC form signature

I’ve read the interesting post at Who is the electrical installation designer? - IET Engineering Communities (theiet.org) on “Who is the electrical installation designer?” but my thought is somewhat different else I would have tagged onto that thread.

I’ve also read the posts at  Electrical Design Courses & Regulations Recommendations (London, UK) - IET Engineering Communities (theiet.org) regarding the training and competence needed for electrical design and having been involved in electrical works for a considerable period am familiar with the significance of this role. Indeed, when I ask for new works of a small size direct to an electrical contractor I always ensure that the wording of taking on board design liability is included, this such that they are clear and can also charge for that work and its responsibility.  Larger works may be by an electrical designer such as a consultant.

Considering that the EIC has an entry for design where it states:

FOR DESIGN

I/We being the person(s) responsible for the design of the electrical installation (as indicated by my/our signatures below), particulars of which are described above, having exercised reasonable skill and care when carrying out the design and additionally where this certificate applies to an add1t1on or alteration, the safety of the existing installation is not impaired, hereby CERTIFY that the design work for which I/we have been responsible is to the best of my/our knowledge and belief in accordance with BS 7671 :2018, amended to ….. except for the departures, if any, detailed .as follows:  

What extent of information do readers consider to constitute an electrical design ?   Much of my reference information is in my office and I’ve not been there for 18 months so I thought I’d ask others what they considered to be the minimum information as to what comprises an electrical design for an installation has rather than trawl through other sources.  I thought it would be an interesting discussion point as well.

    I meant for this to discuss the practical requirements or outcomes that made an electrical design which would fulfil the design requirements for recording on an EIC.   There is a requirement for competence and legal responsibilities over design, having a design liability. 

    As an example that got me thinking about this, I could give chapter and verse on a recent experience whereby an electrical contractor confusingly completed an NICEIC EIC to say that both they and an architect designed it and a second contractor I asked to confirm the also poor installation indicated that the M&E consultant designed it.   In my opinion, there was no electrical design at tender stage, only a consultants plan showing locations of lights, heaters etc. with a statement that it must comply with the IEE Wiring Regulations (yes it said IEE and not IET) so it was being left to the contractor to design the electrical installation itself.   

    Surely a design has got to include at least the cable sizes, the circuit protection details by way of RCBO sizes and types, the containment details as sizes should also have been worked out etc.
