but isnt that somewhat of a contradiction? surely self certification is signing a certificate and handing it over to the customer? no?:
An electrical test certificate is just that. It's documented evidence that the installation has been tested in accordance with 7671. It has absolutely nothing to do with Building Regs self certification.
Before anyone carry's some building work within a domestic property details of the work have to be submitted to Building Control before they are started. Depending on the type of work BC may require structural and other calculations to be submitted with the application.
Once the works are approved they are monitored by the local building inspector at various stages to ensure they meet the regs and no corners have been cut.
When the works are complete the building inspector
certifies them and the LABC issues the householder with a Building Regs Completion Certificate. Without this certificate the building/extension is listed as uninhabitable and make re-sale almost impossible.
Up until 2004 the building regs did not include the electrical installation so if the electrical installation was a mess BC could still sign it off.
The building regs consists of a number of parts and in 2004 Part p was added which covers the electrical installation. This means to get BC sign off the electrical installation must also now be up to scratch.
As all electrical installations should only be carried out by people that know the regs and test and document the works it was decided to set up a scheme to allow us to self certify our part of the works, monitored by a few industry bodies like the NIC rather than the existing building inspectors who have no electrical training.
So for domestic works only all you have to do is join one of the self certification schemes who will vet you to make sure you are competent to carry out and test electrical works. You then carry on as normal with one slight change. When you finish your testing you submit details to your controlling body who then pass this onto the LABC. Once they receive the details they will issue the Building Regs Completion Certificate in the normal way to say all works have been done to the current building regs.
Unless you're a member of a self certification scheme BC will not take your word that your installation has been done to the building regs. So for PJ's you will have to submit a building regs application before you start some works and you will have to pay them to inspect it before they will certify it and issue a Building Regs Completion Certificate. As part of their certification they will of course require an electrical test certificate because all installations must have one anyway.
