My Mum also wanted direct cremation, which we organised a few months back and are having a celebration of her life at the 6 month mark.
It seems to be getting more popular now, and due to restrictions it was often a practical choice during the pandemic.
She chose it years ago for various reasons - the environment, not wanting a religious ceremony, cost, not wanting us to go through the difficult arrangements straight away, more time to prepare for a gathering, and more freedom over the time of the event.
Some people found it hard to get their heads around ‘no funeral’ so we had to explain it many times. But people close friends and family weren’t at all surprised at her choice. Knowing how clearly she wanted this did get me through some wobbles when it became a reality. The staff at the crematorium were really lovely and I had a lot of liaison with them.
Also, although it was an ‘unattended’ cremation we could send cards, drawings, photos etc. People sent emails from abroad - all to go with Mum, so that helped us feel connected. The person assigned to our family offered to read out a message written by us siblings and we requested 3 pieces of music. This was all a welcome surprise and helped a lot.
Our personal message would usually be read by crematorium staff (who we wouldn’t have contact with), so we felt very honoured that it was read out by our liaison person - and she said she was happy to do it for us.
Another thing was that a couple of errors from the GP caused some delay in the paperwork but changing the provisional date wasn’t at all stressful. In fact it got delayed twice.
As previous posters have said, there’s no visiting a chapel of rest. But there could still be the possibility at hospital. Mum died at home and very close family who wanted to see her were able to, in person or remotely, but that was possible for as long as a chapel of rest.
Hope this helps explain more - we knew almost nothing a few months ago
