Setting up electricity, water and internet in a Spanish home
You have the keys, the landlord or notary hands over the flat and—no lights, no hot water, no Wi‑Fi. Here’s exactly how to get electricity, water and internet running, what documents you need, typical fees (as of 2026) and when to call an electrician or a gestor.
By Iria Mos·Editor — money, healthcare and housing
Bring NIE (or passport), a Spanish bank account and either the escritura or rental contract — suppliers will ask for them.
Check the CUPS number on any previous bill. If there isn’t one you'll pay for a new connection and a distributor visit.
Get internet booked before arrival if fibre is available where you move — installers are the bottleneck.
Pay an electrician for a ‘boletín’ (certificado) if the property’s installation isn’t certified; it saves weeks of delays.
Opening scene: you’ve just collected the keys
You turn the key. The apartment is clean, the lights don’t come on, the taps are cold and there’s no Wi‑Fi password on the welcome note. This is the practical moment everyone reading this recognises: you need three things working fast so you can live comfortably — electricity (luz), running water (agua) and internet (usually fibre/ADSL).
I’ll walk you through the order that works in the real world, the papers you’ll be asked for, how long each step takes and where things get sticky enough that you should pay for help.
Step 1 — electricity: fast checks and two routes
Electricity is the most fiddly because there are two situations: the meter (contador) is already live or you need a new connection.
If the meter is live
Find the CUPS number on the meter or a previous bill. Your supplier will need it.
Call any commercial provider (Iberdrola, Endesa, Naturgy and many smaller companies). You can change supplier without an electrician — it’s called cambio de titular. Expect to give NIE/passport, bank details (SEPA), address and the CUPS.
On the day you move, photograph the meter reading and email it to the supplier. That avoids being billed for the previous occupant’s usage.
If there’s no live meter or you need a higher power (new connection / alta)
You’ll need a contract with a commercial company and the distributor (local company) will send someone to assign a CUPS and activate the point. This can take from 3 days to 3 weeks depending on the town and whether an electrician must first provide a certified installation (the boletín).
Older properties and properties without a certificate of the internal wiring commonly require an electrician’s certificate (often called a boletín or certificado de instalación eléctrica). Get one up front — it avoids back-and-forth with the distributor that costs time and money.
Practical things to have ready
Documentation checklist (see full checklist below).
If the property is rented, ask the landlord for the last bill (to find the CUPS) and whether they’ll keep the supply active during the handover.
Step 2 — water: municipal process, fewer commercial choices
Water in Spain is handled by the town council or a contracted company. This is usually less technical than electricity but can be bureaucratic.
What happens on day one
Some municipalities allow you to transfer the contract online; others require a visit to the local water office (oficina de agua).
Suppliers will typically ask for ID (NIE/passport), a rental contract or escritura, and a bank mandate. In a few towns you’ll also need to be empadronado — registered at the address. That’s why the empadronamiento is worth doing quickly; it’s explained in our empadronamiento guide: /en/visas-legal/empadronamiento-spain-guide.
Leaky point: outstanding municipal debts
If the outgoing owner or tenant hasn’t paid the council for water or rubbish collection, the town may block transfers until the debt is cleared. Ask the landlord to show the latest bill.
Step 3 — internet: book it first, test later
If fibre (FTTH) is available where you move, this is the single service that most readers should schedule before arrival. Installers are the bottleneck in many coastal towns and islands.
How to speed it up
Check availability online using the address. If fibre is listed, pick a major provider and book the first available slot. Most providers offer a free or low-cost installation as a promotion but the earliest appointment can be two to three weeks out.
If your property needs internal cabling or you want the router in a different room, budget for an extra private technician visit. The ISP’s installer only does the standard drop.
Tip: If you rely on a phone for initial communication, buy a Spanish SIM and prepay data the day you arrive. It makes booking installers and calling suppliers much easier than relying on free Wi‑Fi at cafés.
Who should do what — DIY versus paid help
Do yourself
Contact suppliers, choose tariffs and register with a Spanish bank (you’ll need a SEPA mandate for direct debit).
Photograph meter readings and email them to suppliers; keep copies of any emails and contract numbers.
Pay a professional
An electrician for a boletín/certificado of the installation. If you need one, it’s worth paying for a qualified installer — savings from doing it poorly are nil and the distributor won’t accept an amateur’s paperwork.
A gestor or lawyer if the property has unresolved debts tied to the CUPS or if the sale paperwork is confusing. Paying a gestor saves hours in local offices and can avoid mistakes that leave utilities in the previous owner’s name.
Typical costs and timings (as of 2026 — check with suppliers)
Service
Upfront cost
Deposit / fianza
Typical activation time
Electricity (change of titular)
€0–€60 (often free); new connection €50–€250
€50–€150 for customers without history
1–7 days if meter live; 7–21+ days for new connection
Water
€0–€100 depending on council
€0–€150 (varies by municipality)
1–10 days, sometimes longer if office visit required
Internet (FTTH)
€0–€100 (promos often free)
Usually none
3–21 days; rural or islands slower
These are ballpark figures. Promotions, local rules and the distributor’s backlog change things quickly—ask for an itemised quote.
Documentation checklist
Passport and NIE (or passport if you don’t have an NIE yet). If you haven’t got a NIE, suppliers will sometimes accept a passport plus a fiscal number (NIF) request receipt — but it’s messier.
Escritura (title deed) or rental contract (contrato de arrendamiento) with landlord contact details — utilities often won’t switch without proof of tenancy/ownership.
Last bill with CUPS number (if available).
Spanish bank details (IBAN) for direct debit (SEPA mandate).
Boletín eléctrico (certificado) if the electrician or distributor requests it — commonly needed for new supplies or very old installations.
Empadronamiento certificate if the supplier requests proof of residence.
Questions to ask a lawyer, gestor or broker
Are there any outstanding municipal or community debts tied to the address that could block water or electricity transfers?
Has the CUPS been cleared of previous debts, and how do we transfer it cleanly into my name?
Do I need a boletín for this property based on its age and previous certifications?
If I rent, what does the rental contract say about utilities — who pays what and who is responsible for changing the titular?
Any local rules (island councils, special communities) that affect connection times or costs?
FAQ
Do I need an NIE to open utilities in Spain?
A NIE makes everything simpler and most suppliers will ask for it. Some companies accept a passport for a short-term contract or will allow you to register while your NIE is pending, but you’ll be asked to supply the NIE when it arrives. If you face problems, a gestor can step in and speed things up.
What is a boletín eléctrico and when is it required?
The boletín is a certificate from a qualified electrician stating the internal wiring meets safety rules. Distributors commonly require it for new connections, when the installation lacks paperwork, or when higher power is requested. Don’t try to avoid this — a certified electrician is cheap compared with weeks of waiting for a distributor to accept your connection.
Can a landlord keep my utility deposit?
The landlord can only keep money if the contract allows it and you agreed it. A separate deposit for utilities is uncommon; normally the landlord pays rates and the tenant pays monthly consumption. Check your rental contract and, if in doubt, a gestor or tenant-rights guide like /en/housing/rental-contracts-spain-tenant-rights will help.
How long does fibre installation take?
If fibre is already in the building: usually 3–10 working days from booking. If the feeder needs to be run to the building or a local contractor is required, expect 2–4 weeks. Book the earliest slot you can and have a fallback (SIM with tethering) for the first few days.
How do I know if there are unpaid bills attached to an address?
Ask the seller or landlord for recent utility and council tax (IBI) bills. If you suspect a problem, a gestor can check the CUPS and municipal records for outstanding charges. That’s one of the few times paying for help is worth it — unresolved debts can block new contracts.
If you’re planning the move, do the empadronamiento early and book your internet slot as soon as you have an address. For electricity, take a moment to find the CUPS and a copy of the last bill — it will save you time and a small pile of frustration.
Iria works between Spain and France and comes from the same corner of the tourism sector, the part that ends up answering questions about doctors, contracts and money rather than beaches. On HolaRetire she looks after healthcare, tax and housing, and is the reason those guides quote figures and form names instead of generalities.
Before you hand over a deposit, get — and read — the nota simple. This short extract from the Registro de la Propiedad tells you who legally owns the finca, any registered mortgages or embargos, and the formal description. Ask for a fresh one, know the red flags, and insist on a certified copy if anything looks off.
Think the Costa Blanca is cheap everywhere? That mistake costs people money and regret. This guide (with 2026 price ranges) tells you what different budgets actually buy, where to spend and where to save, running costs, healthcare access, and the social reality — plus the small print about taxes and residency.
If you want sun, short flights to the UK/Canada/Australia and a mix of quiet villages and lively seafront towns, the Costa Blanca delivers — but the right town depends on your budget, need for English services, and tolerance for summer crowds. This guide picks the best areas for different retirees and explains the costs and paperwork you'll actually face.
Spanish houses behave differently in winter: some are warm, some are cold, and the difference is usually insulation and the heating system rather than latitude. This guide tells you what systems you'll find, which fixes you can do yourself, which need a pro, and the practical next steps before you sign.
