southern electric have said they do checks , you have to pay 4pound a month via dd , and that coveres unlimted call outs , parts and labour , but if you need something like a new fuse box etc then thats a chargeable job , so ive signed up for that , my local council do free home safety checks but you have to have a child under 5 , be disabled or be over 65
so that dont apply to me but i will be ringing them to see if they offer anything else .
£4 a month wont include a PIR so if it's unsafe it won't make any difference. A home safety check isn't going to include formal inspection & testing of your electrics.
If you are concerned you should contact your landlord in writing, as JohnD told you on your other thread.
