Connection to electricity mains for a greenfield site

Hi all

I’m looking to get electricity connected to my greenfield rural site.


Below is the scope of works I’ll be sending out to get quotes. Appreciate if anyone can let me know if I should ask for anything else and also how long it took for people to get connected from start to finish. Looking to have a large transformer for plenty of headroom capacity.

Thanks
