I'm moving into my new house with harry today... yay! At last!

HOWEVER. I've gone blank on what i need to do with bills etc? Do i have to sort it all today?

Should they already have my details from the landlord?

I've been panicing since 5 this morning! Help! xxxx

You need to take any meter readings i,e gas, water & electric from your old place and also at your new place.
I move next week and have been keeping all letters, so when i move i can contact all relevant and give them my new address.
Don't forget to alos change your address with doctors, dentist, driving licence, car and home insurance, school (if necessary), inland revenus (if claiming tax credits), bank, council tax
