as promised here's the reply I received to my email.
Dear Mr Davies,
Thanks for your email and I am sorry if you have found our campaign offensive – that is of course not our intention.
Electrical Safety First promotes registered electricians as householders have the peace of mind that, should something go wrong, there is a procedure in place to investigate any complaints about registered electricians who have not worked to the UK safety standard BS 7671. There is a huge lack of public awareness around the fact that certain work can only be carried out by electricians registered with one of the government-approved schemes, which is another area of focus for our campaigns.
I hope you understand our reasoning and again apologies for any offence caused.
Kind Regards,
Ben
