I have said on here several times that it is perfectly legal just to have the body delivered direct to the back door of the crematorium and fed straight into the oven with no ceremony at all.
A coffin is not necessary either just a shroud or a body bag. You do not need a hearse a man with a van or someone with a big estate car can deliver the body.
This is the cheapest way to legally dispose of a body
Death certificate and cremation clearance certificate say £35.
Van to the crem another £35 , cremation fee around £300 , body bag £11 on eBay.( I intend buying a bulk pack of 50 body bags from eBay USA , keeping one and selling the rest, the profit should pay for my cremation, you can get them for £2 each in bulk from USA)
You should get change out of £400.
Then get a relative who is on benefit or pension to apply for a funeral grant £1200 ! That leaves at least £800 for a p*** up at my local boozer in memory.
