Balders, you simply don't understand.
The inclusion of electrical installations into the Building Regulations is long overdue. It is now controlled, just as structure, fire safety, ventilation, hygiene, drainage, combustion appliances, conservation of fuel and power (to name but a few) are. This means that the work must be carried out to comply with certain minimum standards. (How do you think builders feel, having to cope with inspections on evey aspect of every job?)
Sparkies have been crying out for this for decades.
So now it's here, you whinge? Just because somebody wants to make sure you're not just another cowboy? You've had around four years' notice to get to grips with all this (the legislation's been in force for almost two years!). The only reason I can see that you're complaining is because you don't get it.
And anyway, let's face it, your argument is probably specious because you'll go ahead and do the work regardless.
By the way, an election will make no difference; the only lobby to revoke part P is a few disgruntled, under-achieving tradesmen from a single trade. How much notice would you take?
Grow up.
