From our point of view - these are the easiest!
A detailed analysis of requirements and intended use is carried out with the owner - from which an installation plan is drawn and approved.
We work in close collaboration with the builder, and ensure that the correct cabling is installed into the new build as it is constructed.
After the build has been plastered, the final fix phase is carried out where the various fittings are installed and the complete system is checked and verified.
A Building Regulation Compliance Certificate (BRCC) is then issued and filed with the local council.
