Setting up utilities in Spain means sorting electricity, water, often gas, plus internet and a mobile. Each is a separate contract with a separate provider, paid by direct debit (domiciliación) from your Spanish bank account. When you move in — whether you buy or rent — the existing supplies usually need transferring into your name (a cambio de titular) rather than reconnecting from scratch, which is faster and cheaper. You'll generally need your NIE, passport, Spanish IBAN, the property address and supply references, and sometimes the certificado de instalación / boletín (electrical certificate) for a new or long-disconnected connection. Most expats find the language and admin the hard part. We set up and transfer utilities for clients as part of relocation and property support — get the whole household connected in English on a clear quote.
How Utilities Work in Spain
In Spain, each utility is a separate contract with a separate company, and almost all of them are paid automatically by direct debit from your bank account. You don't get a single "household bills" account — you deal with the electricity company, the water company (often the town hall or a local concession), the gas supplier if you have mains gas, an internet/telecoms provider, and a mobile network, each with its own contract, customer service and recibo (the charge that lands on your statement).
The key practical points for an expat are: nearly everything runs on domiciliación, so you need a Spanish bank account with a Spanish IBAN to point the debits at; the supplies on a property you move into usually already exist and need transferring into your name (cambio de titular) rather than connecting fresh; and much of the process is conducted in Spanish, by phone or through provider apps, with paperwork. None of it is difficult once you know the route, but the combination of language, admin and the sheer number of separate accounts is what makes setting up utilities one of the more frustrating parts of settling in — and exactly the kind of thing we take off clients' hands.
The Main Utilities
Here's the quick map of what you'll be setting up, with a dedicated guide for each:
| Utility | What to know |
|---|---|
| Electricity | The big one. Variable bills, a chosen contracted power (potencia), and a regulated or free-market tariff. Electricity guide → |
| Water | Usually supplied by the town hall or a local concession; relatively low cost, billed periodically. Water guide → |
| Gas | Mains gas in some areas; bottled (butano) or tank gas elsewhere — depends on the property. Gas guide → |
| Internet & broadband | Fibre is widespread; usually bundled with mobile and sometimes TV. Internet guide → |
| Mobile phone | Contract or prepaid SIM; easy to set up, competitive market. Mobile guide → |
Alongside the core supplies, settling in also involves Correos (the postal service), refuse and recycling (often charged via the town hall as the basura tax), and getting to grips with public transport — all covered in this silo. The electricity contract is the one to get right first, because it's the most expensive, the most variable, and the one where the wrong choice of tariff or contracted power costs you month after month.
What You'll Need
To set up or transfer utilities, you'll generally need to have ready:
- Your NIE and passport (the foreigner ID number is needed for the contracts).
- A Spanish bank account and IBAN to set up the direct debit.
- The property address and supply references — for electricity, the CUPS (a unique supply-point code); for water and gas, the relevant account or meter reference.
- Proof of occupancy — your deeds (escritura) if you bought, or the rental contract if you rent.
- The electrical certificate (boletín / CIE) for a new connection or a supply that's been disconnected for a long time.
For a straightforward change of name on an existing, active supply, you usually don't need the boletín — that's mainly for new connections or long-dormant ones. The CUPS code for electricity is the single most useful thing to find: it's on any old electricity bill for the property and identifies the supply point precisely, making the transfer far smoother. We gather and check all of this for clients before approaching the providers, so the set-up goes through cleanly rather than stalling on a missing document.
Find the CUPS before you start
The CUPS is the unique code identifying an electricity supply point (it's on any previous bill for the property). Having it to hand makes transferring or contracting electricity far quicker. Ask the seller, landlord or agent for a recent bill so you have the CUPS, water account and any gas reference.
The Move-In Changeover
When you take over a property, the supplies are usually already connected in the previous owner's or tenant's name. The job is to change the holder (cambio de titular) and point everything at your account, not to connect from scratch — which would be slower and dearer. Here's the sequence:
Get the supply details from the seller or landlord
Ask for recent bills so you have the CUPS (electricity), water account, gas reference and the names of the current providers.
Change the holder into your name
Contact each provider to do the cambio de titular, supplying your NIE, IBAN and proof of occupancy. The supply keeps running — only the account holder changes.
Set up the direct debits
Point every utility at your Spanish IBAN so the recibos are paid automatically.
Review tariffs and contracted power
Once in your name, check the electricity tariff and potencia are right for you — the previous occupant's choices may not suit your usage.
The most common slip is leaving supplies on the previous occupant's name and bank details, which causes confusion, bounced payments and even disconnection when their account stops paying. Doing the changeover properly at move-in — ideally alongside the property purchase or the start of a tenancy — saves months of muddle. For new-build or long-empty properties, you may need a fresh connection with a boletín rather than a simple transfer, which takes longer; we identify which route applies and manage it.
Common Mistakes
The errors that cost expats time and money are predictable:
- Leaving supplies on the old holder's name — the single biggest cause of trouble; payments bounce and supplies get cut.
- Choosing the wrong contracted power (potencia) — too high and you overpay a fixed daily charge; too low and the trips cut out. The electricity guide explains how to get this right.
- Staying on a default or inherited tariff — the previous occupant's tariff, or a sales-pushed one, may be far from the cheapest for your usage.
- Using a foreign IBAN for the debits — occasionally rejected; a Spanish IBAN avoids friction.
- Letting the account run low — a bounced utility recibo can lead to disconnection, which is a costly hassle to reverse.
None of these are catastrophic on their own, but together they explain why so many newcomers find utilities stressful. The fix is to do the changeover thoroughly, choose tariffs and power deliberately, fund the account, and keep an eye on the bills — or to have someone do it for you. We set the whole thing up correctly from the start so these problems never arise.

It's part of our relocation and property support, and our gestoría service can keep an eye on the bills for non-resident owners. Everything in English, on a clear quote — extras such as connection fees charged by the providers are separate. Book a consultation to get your utilities sorted.
Frequently Asked Questions
Each utility — electricity, water, gas, internet, mobile — is a separate contract with a separate provider, paid by direct debit from your Spanish bank account. When you move into a property the supplies usually already exist and need transferring into your name (cambio de titular) rather than connecting from scratch. You'll generally need your NIE, passport, a Spanish IBAN, the property address and supply references (such as the CUPS for electricity), and proof of occupancy. The language and admin are the hard part for most expats. We set up and transfer utilities for clients in English on a clear quote.
A cambio de titular is a change of account holder on an existing utility supply. When you take over a property, the electricity, water and gas are usually already connected in the previous occupant's name — so rather than connecting from scratch, you change the holder into your name and point the bills at your bank account. This is faster and cheaper than a new connection, and the supply keeps running throughout. We handle the cambio de titular with each provider for clients.
You'll generally need your NIE and passport, a Spanish bank account and IBAN for the direct debit, the property address and supply references (the CUPS code for electricity, plus water and gas account references), and proof of occupancy (your deeds if you bought, or the rental contract). For a new connection or a supply disconnected for a long time, you may also need the electrical certificate (boletín / CIE). For a simple change of name on an active supply, the boletín usually isn't required. We gather and check all of this before approaching the providers.
The CUPS (Código Universal del Punto de Suministro) is a unique code identifying an electricity supply point. It appears on any previous electricity bill for the property and is the single most useful thing to have when transferring or contracting electricity, because it identifies the supply precisely and makes the process far smoother. There's an equivalent reference for gas supply points. Ask the seller, landlord or agent for a recent bill so you have the CUPS to hand before you start.
In practice, yes. Almost all Spanish utilities are paid by direct debit (domiciliación), and while EU rules say a eurozone IBAN from any country should be accepted, some providers still prefer or effectively require a Spanish (ES) IBAN, and foreign IBANs are occasionally rejected. Setting up your utility direct debits from a Spanish-IBAN account avoids friction. This is one of the main reasons expats open a Spanish bank account. We make sure your account is in place and all your providers point to it.
Electricity. It's the most expensive utility, the bills are variable, and the choices you make — the tariff (regulated or free-market) and the contracted power (potencia) — affect what you pay every month. The wrong contracted power means either overpaying a fixed daily charge or having the supply trip out; the wrong tariff can cost you significantly over a year. When you take over a property, the previous occupant's electricity choices may not suit you, so it's worth reviewing them. Our electricity guide explains how to get this right, and we review tariffs and power for clients.
A simple change of name (cambio de titular) on an active supply is usually quick — often a few days. A new connection, or reconnecting a supply that's been off for a long time, takes longer because it may require an electrical certificate (boletín) and an inspection, and can run to a couple of weeks or more depending on the area and provider. Internet installation depends on whether fibre is already at the property; where it is, it can be fast. We identify which route applies to your property and manage the timing so you're not left without supply.
Yes. We regularly set up and manage utilities for non-resident owners who aren't in Spain to deal with the providers themselves. We handle the contracts and changeovers, point the bills at the right account, and our gestoría service can monitor the supplies and bills so nothing bounces or gets cut off while you're away — a common problem for absent owners. It's part of our relocation, property and gestoría support. Book a consultation and we'll set up everything your Spanish home needs.
