Called up the utilities companies to change to my name. All different procedures.
Electricity customer service advised me to not change for another month. When the next bill arrives, call up to cancel the autopay and let the deposit pay for the bill. Then change name. I thought it was great advice.
Gas needed a fax or email with all sorts of certificates, include proof of relationship. Really? But then once I emailed it was done quickly.
Water took my details over the phone and that was it.
