I must admit I’ve never done the extreme side of it, I have a business associate that has been doing this work for a very long time who I know very well, I have seen and looked in on some bad jobs, as far as I know the insurance company will settle the invoice in some cases, sometimes the police, the local authority/housing association, or the family.
I can say that he does very very well from this type of work, the £500 figure mentioned is well below the average price.
This is only a small part of what he does, other services would include: fumigation, removal of dead animals or birds, shuttering properties, alarms, sharps removal, fogging, void valets, graffiti removal etc etc.
We do carry out some of the work ive mentioned, but as of yet not the extreme side of it.
