Changes in what Building Control can charge for changed in October 2010. Now they can charge for any external costs on top of the usual notification fee. This can double the cost of notification from (typically) £150 to £300 where they call in an electrician to check for compliance. BC would normally do this because they lack the capability of doing it themselves.
That more or less rules out DIY wiring installations that should be notified on cost grounds: it's cheaper to employ a registered electrician.
On the other hand, in the five years since part P of building control has been in operation, no householder has been prosecuted for breaches; only cowboy electricians. I have some sympathy with DIYers who are competent and who (erm) comply with this legislation with the same diligence as they comply with speeding, parking and copyright legislation.
