Ok we are getting into specifics now.
Just clarify what Other Clive has suggested. There is a difference to between brand new electrical installations and extensions to electrical installations.
It is both reasonable and a legal requirement that a new total installation or rewiring of a an installation must be carried to be compliant with the the current IEEE wiring regulations. The law does not specify who must do the work, only that the works must be signed off by an approved installer.
Because the signing off means the tester is accepting responsibility for the installation and its compliance and safety, it is actually quite difficult to find an approved tester who will sign off work they have not done or at least witnessed being done by themselves.
Unless the tester is fully aware of the installers capability and integrity they are unlikely to sign off work just based on instrumentation measurements, without exposing at least some of the underlying work.
These days home owners can undertake certain basic repairs such a replacing switches and sockets, but any additions to a fixed wiring system will probably fall under a part P requirement.
Gas however is a different matter. It is a legal requirement for ALL* gas fitting to be under taken by a ticketed professional - That is the law - *except for privately owned touring and self propelled motor caravans used exclusively by the owner! This is one a of a few very specific exceptions written into the Gas Safety (Installations and Use ) Regulations, and it basically allows any owner to undertake gas installation and repairs in their own private touring caravan or motor home. No one else but the owner has that dispensation, so for example the owner cannot ask any one else to do the work (not even a family member) unless they are ticketed to work on the system.
Even though the law allows owners to work on their own touring caravan or motorhome, the requirement for the design and quality of work to be up to standard still stands, and of course that include the pre and post testing of the system for compliance.
If the touring caravan is lent or hired out in any form then the dispensation does not apply - so consider that if you take a family on holiday it could be construed that you are hiring/loaning the caravan to the rest of your family and as such they have the individuals right to expect that all gas and electrical systems are fully up to legal safety standards.
As a past professional in the field, I can see the sense behind these legislation's. Its not to create work for the boys, but it is to drive up standards of safety.
This is not an attempt to stifle DIY which is how some seem to interpret the law, but its is to try and ensure that at least for some hazardous materials and process, proper due care is exercised, and that can only be achieved if the DIY'er is aware of the restrictions that apply.
Unless Haymarket or admin or moderators ask me not to post. I will continue to offer measured advice based on the questions we receive. If those questions raise alarm bells about the proberty of a questioner's ability or knowledge then I reserve the right to point it out.
I would rather be accused of over caution, than to find someone has done something stupid and injured themselves or someone else.
