There has been much discussion on this forum about the pros and cons of employing the services of someone other than a Registered Electrical Contractor (REC) to do electrical work in the home. Other than RECs home owners (rightly or wrongly) can choose from:
⦁ DIYer's, "handymen"
⦁ Builders
⦁ Plumbers
⦁ Unregistered electricians
⦁ Registered Gas Installers (RGI)
⦁ Alarm installers
⦁ Technically skilled people (such as electrical engineers) with recognised qualifications
There is also some confusion about what is and is not permitted from a legal perspective.
If this thread is successful perhaps it could become a sticky (it may need a bit of tidying up) people could be referred to this thread rather than repeating the same points over and over again.
Here are a few headings that could be discussed:
1) Electrical safety
2) Familiarisation with the most current wiring rules
3) Insurance
4) Certification
5) Cost
6) Standard of workmanship / quality / aesthetics
7) Technical expertise
8) Recourse should something go wrong
9) Design
10) Impact on the value of the home
Discuss and please keep it friendly

Edit: For the record I am not a REC. I am not a fan and of anyone other than a qualified electrician doing most electrical work. I have extensive experience dealing with RECs and it has been overwhelming positive.
