Setting Up Utilities in Spain After Your Mortgage Completes
Signing at the notary is not the final step. Once your Spanish mortgage completes, you still need to move electricity, water and community fees into your own name in Spain, using the same NIE and Spanish bank account that got you through the purchase.

Why utilities deserve attention right after completion
Buyers from the United Kingdom often focus all their energy on the mortgage approval and the notary appointment, and understandably so. But the practical side of owning a home in Spain starts the moment you receive the keys, and utility companies and the community of owners will not update their records automatically.
This piece walks through what a new non-resident owner typically needs to do in the weeks after completion: changing the electricity and water contracts, registering with the community administrator, and understanding how these tasks sit alongside your ongoing Spanish tax obligations.
Keep your NIE, passport and Spanish IBAN together after completion; almost every utility and community request in Spain will ask for all three.
From Notary to Your Name: The First Practical Steps
Completing the purchase of a home in Spain is a major milestone, but the day after signing at the notary, a separate and very practical task begins: moving electricity, water and community fees into your own name. None of this happens automatically. The notary formalises the deed of sale, and the land registry then updates its records over the following weeks, but utility companies and the community of owners only act once you, as the new owner, contact them directly.
For this stage you will need the same tools you used to get the mortgage: your NIE, a Spanish bank account and a valid passport. Keep the signed deed (escritura) and the last bills issued to the seller close at hand, since every company will ask for proof that the property is now yours and a reference to the previous account holder.
Electricity and Water: Changing the Contract Holder
In Spain, electricity is usually supplied by a company operating across the area, while water is normally managed by a municipal or regional provider. In both cases, you will generally want to request a change of holder rather than opening a brand-new contract, since this keeps the existing meter and supply point active and avoids the longer process of connecting a completely new line.
The company will typically ask for your NIE, passport, the deed or at least the land registry note confirming you as owner, a recent bill issued to the previous owner, the IBAN of your Spanish account for direct debit, and sometimes a meter reading taken on the day of completion. Response times vary by company and by Spain, but it is sensible to start this within the first couple of weeks, since bills continue to be generated in the seller's name until the change is processed.
Unpaid community fees in Spain can remain attached to the property itself rather than just the person who owed them, so ask the seller's agent or the notary for written confirmation that the account is clear, and keep that document together with your deed.
Community Fees and the Building's Management
If the property in Spain forms part of a building or urbanisation with shared areas, such as a lift, a garden or a pool, you automatically become a member of the community of owners and will owe periodic fees. These are usually handled by an administrator, who should be informed of the change of ownership so that future notices, meeting invitations and payment requests reach you rather than the seller.
As a non-resident, owning property in Spain also brings yearly tax duties that are separate from utilities but worth noting here: you will need to file the annual Modelo 210 non-resident income tax return, and if you ever sell, the buyer will withhold 3% of the price on account of your tax. Spain and the United Kingdom have a double taxation agreement, and a local tax adviser can confirm exactly how this fits with what you already declare to HMRC.
NIE
Still your key document
Your NIE does not expire once the mortgage is signed. You will use the same number with electricity and water companies, the community administrator and the Spanish tax office every year that you own the property.
Typical Documents Utility Companies Ask For
Requirements differ from one company to another, but most ask for a similar set of documents when you switch an electricity or water contract into your name in Spain.
Having them ready in advance, together with certified or sworn translations if a particular office requests them, speeds up the process considerably and reduces the risk of your first bills being delayed or sent to the wrong name.
| Step | Approx. time | Main contact |
|---|---|---|
| Change electricity holder | 2 weeks | Electricity supplier |
| Change water holder | 2 weeks | Municipal water company |
| Register with the community | 1 week | Building administrator |
Practical Checklist for New Owners
- Keep your NIE, passport and Spanish IBAN handy for every call, form or online request.
- Ask for a change of holder, not a brand-new contract, whenever the supplier offers it.
- Request written confirmation from the seller that community fees and bills are settled up to completion.
- Register with the building administrator as soon as you collect the keys.
- Set a reminder for your first Modelo 210 filing as a non-resident owner.
- If you are back in the United Kingdom, check what can be finished by phone, post or power of attorney before you leave Spain.
If you live in the United Kingdom
Spain is a relatively short flight away from most UK airports, making regular visits to a Spanish property straightforward for owners based in Britain. Many British buyers are drawn to Spain for its climate, coastal lifestyle and established expatriate communities. One practical point to bear in mind is that Spanish inheritance law differs from UK rules, so it is worth taking specific advice on how it may affect the property and one's estate. Currency movements between sterling and the euro can also affect the overall cost of purchase and ongoing expenses.
What a Spanish bank will usually ask you for
- Proof of income: recent P60 and payslips
- Last filed UK tax return (Self Assessment)
- Bank statements from the last three to six months
- Evidence of existing loans or mortgage commitments
- Valid passport or UK national identity document
Tax at home and in Spain
Spain and the United Kingdom have a double taxation agreement in place, and a local tax adviser should confirm how rental income or gains from Spanish property must be declared and reported to HMRC.
Staying in Spain
As the United Kingdom is no longer an EU member state, British citizens may stay in Spain for up to 90 days in any 180-day period without a visa, and must apply for a visa or residence permit for longer stays.
Since the United Kingdom uses the pound sterling (GBP) rather than the euro, buyers should factor in exchange-rate movements and currency conversion costs when paying for a property or transferring funds to Spain.
Frequently asked questions
Do I need to be in Spain in person to switch the utilities, or can it be done remotely?
Most companies in Spain allow you to start the change of holder by phone or online once you have your NIE and Spanish IBAN, though some still ask for a signed form or a visit to a local office. If you are back in the UK, remember the 90/180 day rule applies to your stays, so plan any in-person steps during a visit or use a trusted local contact.
What happens if the previous owner hasn't settled the last electricity or water bill before I take over?
Outstanding bills are usually the seller's responsibility, but unpaid community fees can remain linked to the property itself. It is worth asking the notary or the seller's agent for a certificate confirming all fees and bills are settled up to the completion date, and keeping it with your deed in case a company or the community raises the issue later.
Will I need a Spanish bank account just for utility bills, or can I pay from my UK account?
You will already have opened a Spanish bank account to complete the mortgage, and that same account is normally used for direct debits with electricity, water and community fee providers. Paying from a UK account directly is rarely accepted for routine domestic bills, and currency conversion costs would make it impractical for small, regular payments.
Do I have to pay Spanish tax on the property on top of the utility bills?
Yes. As a non-resident owner you will file an annual Modelo 210 return, separate from your utility payments. Spain and the United Kingdom have a double taxation agreement, so a local tax adviser can confirm exactly how any rental income or future gain should be reported both in Spain and to HMRC.
How soon after completion should I contact the electricity and water companies in Spain?
It is sensible to start within the first couple of weeks after signing at the notary, since bills keep being issued to the previous owner until the change of holder is processed. Delaying can mean disputed payments or a short interruption in supply while the paperwork catches up with the new ownership.
