Depends on your background and financial status.
My mums funeral cost about $9000 cdn which is around £4300 or so.
I had a sikh and hindu wedding (wife is hindu) so it was costly to a point. We cut down on a lot of guests which in the indian way is impossible. But we did it. Costs in uk vs north america may be different because we do things slightly different here but lets just say it was sligtly more than triple my mums funeral for sure. Thats being conservative considering what my cousins and close friends have spent.
