Signing off electrical work in the UK

What exactly do you need to be able to sign off electrical work in the UK?

As you might have gathered, there's no simple answer to that. The wiring regs simply ask for whoever does the work (design, installation & verification) to sign for their own work, and to be 'skilled and competent' without specifying any qualifications or membership needed to justify that.

Normally you'd need some insurance to cover you back, so you might find your insurer will have some more specific requirements for qualifications (or want to charge you a much larger premium on the basis that they can't have as much confidence you won't get into trouble).

For commercial work, the main mechanism for regulating was membership of an organisation that tried to ensure a good standard of work was done - traditionally that was the NICEIC but there are many others (e.g. NAPIT) too these days. Membership isn't compulsory but as the majority of commercial specifiers would only offer work to members of such organisations, it became pretty much 'the norm'. The advent of part P of the building regulations (for domestic work) muddied the water somewhat,  as that introduced the need for 'Registered Competent Persons' schemes for domestic work and all the traditional bodies picked up that responsibility too - but be careful - there are often different types of membership covering different areas (domestic, commercial) and differing scopes (simple installation, more complex installation, periodic inspection etc.) which all appear at first glance to come under the same logo. All the schemes will insist on some level of qualification in order to join (usually City & Guilds) - the exact requirement depending on the membership level and your circumstances (previous qualifications, experience etc.)
