Right, I think I have figured out the pricing strategy of electrical inspection costs for my local BC office now.
I sent off for the relevant information on notifying building works (on a completely unrelated matter), and the information I received appears to apply to Part P of the building regs also.
There is a table, with "Builder's estimate" in one column "Inspection cost" in the other. It starts with £75 for works up to (if I recall) £1000, and the inspection cost increases with works cost. At £101,000 works cost, the inspection fee is about £250. I will verify these figures when I get home, I just had one of those burning bush moments and it dawned on me that THIS is the cost of inspection, at least for my BC area.
Now, it would seem these costs apply to ALL works, including special trades, where independent inspection and certification is required. However, seeing as with DIY work the labour cost is zero, DIY electrical works will generally fall into the lowest bracket unless you are doing something really big. After all, you could always price your £50-a-socket designer accessories as £1.40 budget items that you later upgraded (notification not required as it was an existing circuit). Perhaps there would be disagreement as to whether this upgrade can be performed before or after certification, and for the sake of £10 difference in inspection costs, I doubt I would bother to argue the point!
