Some interesting reading here . Looks like electrical distribution accounts for about 10 - 12% of dwelling fires over the last 3 years yet cooking appliances account for 52% of the dwelling fires in the same period. Pity they don't further breakdown / analyse the cause of the electrical distribution fires which obviously includes the DNO equipment
It seems to be with the new amendment acceptable to contain a fire which IMO could pose a greater risk by it not being detected early than to actually review why the numbers of fires have increased so dramatically over the last few years.
Using the LFB stats it could be argued that the number of consumer unit fires is 11 times greater now than 6 years ago, 5 times greater now than 5 years ago and 3.5 times greater now than 4 years ago, so should the IET be looking a little closer to home as it would appear that this has all happened under the 17th edition regs couple this with Part P increasing the safety of electrical work in the domestic sector and the perceived skills shortage that was addressed with 17 day and 5 week courses it really does give food for thought as to whether anybody has actually looked at the bigger picture
The last 5 - 6 years has probably seen the highest number of consumer unit swap outs due to not being "compliant" with the 17th edition since electricity came into general use given the factors highlighted previously is it any wonder why this is happening statistics can have a use but are generally flawed by a lack of analysis or swayed by those producing them and can provoke knee jerk reactions that don't actually address the cause as appears to be the case with this change.
The "eg metal" has been jumped on to prempt wholesale change to metal consumer units without looking at whether any of the moulded variants comply or could comply with modification are we going back to the days of that rusty consumer unit on the garage wall because metals good plastic is bad.
This issue could have been dealt with by amending the building regs with the type of consumer unit installed or housing containing it based on risk to occupants should a fire occur if it is in the escape route

Great post. These stats are alarming. NC DBs ain't going to change anything I suspect though
