Utility transfers are usually the most confusing procedure after a property sale
Each provider has different requirements, sometimes the supply point data (CUPS / contract number) is missing, and tracking is done via emails or calls with no clear status.
What usually happens (and goes wrong)
- Scattered documents (DNI, previous bill, contract, deed…).
- Uncertainty about readings and correct date (signing vs. key handover).
- Missing CUPS or supply point data.
- No clear status tracking: "has it been requested?", "accepted?", "anything missing?"

Frequently asked questions
Common queries about utility ownership transfers after a property sale.
When is the best time to transfer utilities: at signing or key handover?
The common practice is to use the key handover date as the reference, as that is when the buyer takes over the property. That day is the most suitable for providing readings and splitting usage. If your agreement specifies a different date, it is advisable to follow what was agreed.
Can the transfer be processed without the previous owner?
It depends on the provider. Many allow the new owner to request the transfer by providing documentation, and sometimes an authorisation if a third party manages the process. In any case, it is advisable to have the CUPS/contract number and a reading if applicable.
What if I don't have the CUPS or a previous bill?
The CUPS usually appears on previous bills and sometimes also on supply point documentation. If you don't have it, the process may require contacting the provider or recovering the data with additional supply information.
