Entirely agree. In the National Park here, the authorities interpret the regulations to mean that anything larger than 1m^3 needs (expensive) approval - so many just go ahead anyway and hope that no one will notice. So the authorities do aerial surveys periodically to check.
The new system for home electrical work approval is going to be expensive - many times the cost of the materials for many jobs. This is mostly a poor rural area (apart from those with holiday homes) so there are plenty of people with reasons to do the work without telling. Most will get it right, as they do now. The few that don't will be called to account if anyone gets hurt - so maybe they will think a little more about what they are doing. At present, almost anyone* could wire the
240V house system with bell wire and use, "didn't know that was dangerous" as an excuse.In one way it may end up even more dangerous - even CEngs who had done a full electrical engineering apprenticeship won't have the necessary authority to do or approve house wiring. So, if their friends are doing any of this stuff in the future, they will have to tell them they can't assist and leave them to manage on their own...
