Couple of things I need to be aware of.
Although I had a rolling boil, about 40 minutes in I partially covered the top and the boil became much more rolling without boiling over.
My mash lost quite a bit of temp despite me wrapping it in a body warmer and towels.
To conserve water I used a fermenting bin filled with water and bottles of frozen water and pump to run the wort chiller.
Wasn't quite as effective as I hoped and had to keep exchanging warm water for cold.
Below is my process.
Constructive criticism welcome

(This was done while looking after my 11 month old as swmbo is away on a hen weekend)

Cheers
