I apologise if I am delayed getting back to you for the rest of Friday and over the weekend because I am only online and off-line sporadically at weekends. Nonetheless, I am online at some time every day.
Legally, getting the accounts in your name should be straightforward. You contact the utility company and give them a copy of the title deed in your name (if they ask for it) and they should open an account.
As simple as that. In fact, they shouldn’t really need the title deeds in your name because you were renting the property for example, they wouldn’t be in your name. They wouldn’t normally ask for the tenancy agreement. The reason for this is that they are not generally unduly bothered if people are volunteering to pay a bill which is what you would be doing by having utilities in your name.
In respect of your late father, all they should need is the death certificate.
If the utility company want some kind of ID which you don’t have, you need to explain to them that you don’t have that and why and ask them what they would find acceptable. They may accept a letter from a solicitor such as the one that dealt with your late father’s estate or they may accept a statutory declaration from you.
Otherwise I’m not certain what the problem is.
