Sorry for your loss.
Go onto all the utility companies websites and search what to do when someone passes away and it will give you the number of the bereavement department.
Water said they would not charge from the date of death, electric company did charge us - both needed meter readings then and when the house was sold.
You will also have to contact his house insurance companies as they may no longer cover the premises if it is empty - there are specialist insurance companies that do this - they will let you know what they expect but the one we used when we sold my Dad's house said we had to turn off the water, electric etc and had to visit often to check on the premises.
Each council is different regarding council tax, the one for my Dad's gave us six months free and when that was up as it was up for sale and empty it was extended for a further year, which we did not need as it completed just after the six months were up.
When you register his death you can then fill in the tell us once service and they will inform banks, councils and government depts and you may get a letter asking you to pay back pension he received or any benefits if they were received at the time of his death.
The bank he was with have you spoken to the bereavement department as they will let you know what items they will pay out of his account etc.
If he had life insurance - when I dealt with my Dads they wanted a death certificate, some wanted it emailed, some just accepted the number on it, they all wanted to know the wording of his will and confirmation of the executors, they all paid me directly into my bank account except for the one that paid the funeral directors directly as that was for that purpose.
If you have a solicitor dealing with the probate and sale they should be able to advise what they will deal with and pay out when the property is sold.
It is one of the wost times and one of the busiest - take your time.
The best thing I did was have a notebook and pen and wrote every companies details on their own page with account numbers and what I had done, when and who i had spoken to, I also went through all his paperwork and got rid of anything that was not important, he was a paperwork hoarder, and put the things needed in a file so it was to hand.
