Electricity, Gas and Water in Spain: Utilities Setup for Americans

Once you have the keys to a Spanish home, setting up utilities as an American mostly means moving its existing electricity, gas and water contracts into your name. On the electricity side, Royal Decree 88/2026, in force since February 12, 2026, lets a tenant step into the current contract instead of ordering a new connection. Piped gas has a regulated last-resort tariff, butane a regulated bottle price, and each town’s utility runs the water. This article is for informational purposes only and is not legal advice; verify current requirements with the relevant Spanish authority or a licensed professional.

What happens to a supply contract left in the previous tenant’s or the landlord’s name?

Royal Decree 88/2026 ties the electricity contract to a person: its holder has to be whoever actually uses the energy (article 28). If you’re a tenant with a valid title to the home, such as a lease, and you’re up to date on payments, you put the existing contract in your own name. In a lease, that’s never treated as a cancellation plus a new connection (articles 31 and 39). Leave it in someone else’s name and it costs you in three ways:

• Payment demands go to the holder. For a main home at 10 kW or less, a cut-off can follow 2 months after the first formal demand for payment (RD 897/2017). That demand lands with the holder, not with you.
• No bono social. The bono social, a discount for vulnerable households, goes only to an individual holding the contract for their habitual home, and it never passes to a new holder.
• A cancellation you did not choose. If the previous holder ends the contract, you sign a new one, and the distributor gets 5 working days from it to connect the supply and fit the meter (RD 1955/2000, article 103). The CNMC, the energy regulator, says 5 to 7 working days.

The good news sits on the regulated side. There, and on the network access contract, the takeover costs nothing and the previous occupant’s unpaid bills stay theirs. On a free-market contract, the contract itself sets the transfer terms. And who pays for what the meters count? You do: the urban leases law, the LAU, puts metered services on the tenant (article 20.3), as the lease guide explains.

Your first two weeks after the keys, step by step

Treat the days as a suggested order, not a deadline.

1. At the handover, photograph every meter and its reading; Seville’s water utility wants a photo of the meter to change the holder.
2. Copy the CUPS (Código Universal del Punto de Suministro) from a recent bill. It’s 20 or 22 letters and digits that identify the home, not the person, and it never changes.
3. Day 1, electricity. Ring the current retailer (comercializadora) to change the holder, or sign with a new one. Have ready what the CNMC lists: the CUPS, your name and ID, the address, the installation certificate (boletín), the power you want and an IBAN. A switch has to be done within 10 working days of signing, or 15 when complex field work is needed (RD 88/2026, article 18).
4. Day 1 or 2, gas. Call the gas retailer to change the holder, asking first whether it charges, or sign with a new one. A switch request must carry your NIF, the Spanish tax number (RD 1434/2002, article 44).
5. Day 2, water. Get in touch with the town’s water utility, with your ID and the lease or deed in hand.
6. Day 3, the padrón. Register on the padrón, the town hall’s list of residents (the empadronamiento guide). A 2008 Comunidad de Madrid leaflet listed a utility contract or annual bill in your name as proof of address, so check your town hall’s current list.
7. Within 14 days, keep or withdraw. A utility contract signed by phone, online or off the company’s premises can be withdrawn within 14 calendar days of signing, or 30 after an unsolicited home visit (consumer protection law, articles 102 and 104).

Electricity: the regulated PVPC or a free-market offer

The PVPC (precio voluntario para el pequeño consumidor, the voluntary price for small consumers) is open to individuals and microenterprises with contracted power of 10 kW or less (RD 216/2014, article 5). Its price moves every hour, though in 2026 futures weigh 55 percent in its energy cost (article 9). You can buy it only from a reference retailer (comercializador de referencia, COR); the CNMC lists Energía XXI, Curenergía, Comercializadora Regulada Gas & Power, Baser, Régsiti and Comercializador de Referencia Energético. Everything else is free market. Moving between the two costs nothing extra if nothing technical changes, apart from the fixed-price penalty below (RD 88/2026, article 28).

Homes at 15 kW or less sit on the 2.0TD network tariff. On the mainland and the Balearic and Canary Islands, its off-peak period runs from midnight to 8:00 on weekdays and covers all of weekends, January 6 and the fixed-date national holidays that regions can’t replace (CNMC Circular 3/2020). To compare, the CNMC comparator ranks current offers against your consumption.

Contract rules under RD 88/2026

The decree lays down these rules for household contracts, with articles 6, 28 and 30 in force since June 12, 2026:

• Leaving. On 2.0TD, an individual can cancel any time with no penalty. The exception is a fixed-price contract before its first yearly renewal, where the penalty tops out at 5 percent of the estimated energy still to be supplied (article 28). The CNMC’s undated consumer page still allows that capped penalty for any first-year permanence clause; I’d go by the decree.
• Switching. No fee on 2.0TD (article 18), and Ley 24/2013 guarantees a switch at no cost (article 44); the old retailer’s final bill has to arrive within 42 days (RD 88/2026, article 6).
• Price changes. You get at least one month’s written notice, and can then leave at no cost.
• Contracted power. One change every 12 months, effective within 72 hours, or 5 working days if field work is needed (article 38).
• Deposits. The guarantee retailers and distributors lodge with the system operator can’t be passed on to you (article 36); no rule read covers other deposits.
• Payment. A free-market contract must let you choose among the usual means of payment (article 30). The EU rule against IBAN discrimination, though, covers only accounts in other EU member states, so plan on a Spanish bank account or another EU euro account.

Gas, butane and water

Piped gas and the TUR

On the gas side, the regulated option is the TUR (tarifa de último recurso, the last-resort tariff), open to individuals supplied at 4 bar or less who use under 50,000 kWh a year. Its prices before taxes from October 1, 2026 come from the resolution of September 30, 2026, which applies the cap of RD-ley 25/2026 (article 1). That cap holds the rise of the raw-material cost to 35 percent over the resolution of June 25, 2026, and the difference gets recovered through the quarterly revisions from January 1, 2027:

The CNMC’s gas guide puts TUR.1 below 5,000 kWh and the TUR at up to 50,000 kWh; the BOE governs. For comparison, the TUR.1 energy term was 4.329798 cents on July 1, 2026. It can move every quarter, and the next revision is due on January 1, 2027.

Gas contract rules live in RD 1434/2002:

• Change of holder. Free only on the old regulated contracts with the distributor (article 39), so ask before you take over a free-market one.
• Free-market contracts. For TUR-eligible customers, they run a year at most, leaving early costs at most 5 percent of the expected energy billing, and you can end a renewal for free with 15 days’ notice (article 38).
• Switching. Free (Ley 34/1998, article 57 bis). Under 100,000 kWh a year, it takes effect on whichever 1st, 11th or 21st is nearest to validation (article 46); the CNMC’s gas guide says 3 weeks at most.
• Inspection. Piped installations get inspected every 5 years, at your cost (RD 919/2006, ITC-ICG 07).

Butane bottles

Bottled butane has its own regulated cap. The resolution of September 8, 2026 sets it at 123.4447 euro cents per kg before taxes from September 15, 2026, about 15.43 euros for a 12.5 kg bottle; no official page gives the price with taxes. Delivery to your door is included, says MITECO, the energy ministry. The price is revised every 2 months, next in November 2026. On top of that, RD-ley 25/2026 (article 3) caps the pre-tax price of bottled butane at the level of the resolution of May 12, 2022 until June 30, 2027, and its preamble puts the 12.5 kg peninsular bottle at 19.55 euros.

Water and the waste fee

• Madrid. Canal de Isabel II, the Comunidad de Madrid’s public water company, lets a tenant sign with the owner’s authorization under its 1975 regulation, or, its contracting guide adds, if the lease says so. Expect an advance on consumption (anticipo de consumo) of one quarter’s bill, refunded at the end minus any debt. For a home already supplied, that advance is the only cost of a new contract (Decreto 3068/1975).
• Seville. EMASESA, owned by the 12 municipalities it supplies, asks for ID (NIF, NIE, the foreigner’s number, or passport), the lease or deed, the installation certificate and a collective padrón certificate, since its tariff blocks depend on how many people live there. Its FAQ, dated July 2022, says a change of holder is free apart from a deposit (fianza), and a new supply (alta) gets connected within 15 working days of contracting and payment.

Then there’s the trash. Ley 7/2022 gave towns 3 years from April 10, 2022 to create a specific waste fee. In Madrid, residents owe it, tenants included, yet the city tax agency bills the owners as their substitutes. Can an owner pass it on without the lease clause stating an annual amount, which the LAU requires for taxes (article 20.1)? The pages read don’t settle it.

Taxes and the bono social on your bills

VAT and the electricity tax

Start with the rates. Electricity and piped gas carry the general 21 percent VAT (Ley 37/1992, article 90); water, sewage and waste collection pay 10 percent under the tax agency’s 2026 rate sheet. Electricity also carries a 5.11269632 percent tax, at least 1 euro per MWh for household use (Ley 38/1992, article 99).

This year the energy VAT went down and came back up. The decree-law RD-ley 7/2026 cut it to 10 percent from March 22, 2026; the rate sheet applies that cut until May 31, and the agency’s news page confirms 21 percent from June 1. RD-ley 18/2026 brought the cut back for August or September only if the June or July price index rose over 15 percent in a year, electricity’s for electricity and gas’s for gas. It didn’t return: the statistics institute INE measured 6.0 and 8.4 percent for electricity and 0.8 and 4.1 for gas. The electricity tax’s conditional cut hinged on the electricity index, and RD-ley 25/2026 says the cuts did not apply in September. That same decree-law sets up the next round. Its articles 18 to 21 cut VAT to 10 percent on electricity (contracts up to 10 kW, and bono social recipients) and on natural gas, and the electricity tax to 0.5 percent, for November and December 2026, but only if the matching INE price index of September (for November) or of October (for December) beats the previous year’s by more than 15 percent, as the tax agency summarizes. For October, no text read on October 1, 2026 sets a lower rate, so the 21 percent VAT and the 5.11269632 percent tax of articles 90 and 99 stand until a condition is met.

The bono social

Under RD 897/2017, the bono social discounts the PVPC and nothing else. The main way in is household income up to 1.5 times the IPREM (the public income index), plus 0.3 per extra adult and 0.5 per minor; large families, minimum pensioners and minimum living income recipients qualify too. The 2023 budget law set the IPREM at 8,400 euros a year in 14 payments, and that budget is still extended into 2026. Run the numbers and a person living alone qualifies up to 12,600 euros a year, as the CNMC states.

How big is the discount? RD-ley 7/2026 sets it at 42.5 percent, or 57.5 percent for severely vulnerable consumers, from January 1 to December 31, 2026. After that, the permanent 35 and 50 percent of RD 897/2017 (article 6) come back unless extended. It applies to every term of the PVPC price up to a yearly energy cap, which MITECO’s requirements page lists as 1,587 kWh for one or two people, 2,222 kWh for three or a minimum pensioner, 2,698 kWh for four and 4,761 kWh for five or more or a large family; a single adult living with minors moves up one band. That page still carries a stale 35 percent sentence; the decree-law governs.

You apply to a reference retailer, which answers a complete file within 10 working days, and the discount lasts 2 years (MITECO). Bring your NIF or NIE and a current padrón certificate (Orden ETU/943/2017, article 2); a U.S. passport alone won’t do. Income is taken from the latest tax year the tax agency holds, or its data for someone not obliged to file; someone who had to file but didn’t is refused (article 4). The order says nothing about a first-year resident.

Complaints, unpaid bills and arbitration

The company comes first. Electricity companies have to answer within 15 working days (RD 88/2026, article 55), and a distributor within 5 working days on metering, bills or undue cut-offs below 15 kW (RD 1955/2000, article 103). Ley 10/2025 on customer service covers water, gas and electricity suppliers: 15 working days, 5 days for billing complaints, sector rules first, and until December 28, 2026 for companies to adapt. Take a complaint to an out-of-court body and collection or a cut-off is suspended until a reasoned decision, unless sector rules say otherwise.

Next up are the Juntas Arbitrales de Consumo, the consumer arbitration boards, and the company has to name the body it has joined. Arbitration is voluntary for both sides and free apart from some expert reports (Consumo). On timing, RD 713/2024 requires the award within 90 calendar days, plus up to 90 in complex cases, while the ministry’s page still says 6 months.

Traveling when a direct debit bounces? The 2-month rule of RD 897/2017 applies, with no cut-off on a holiday or its eve. For bono social recipients, 4 months only trigger a 6-month minimum vital supply capped at 3.5 kW (Ley 24/2013, article 45 bis), and a cut-off can come only after it. Under RD 88/2026 (articles 51 and 52), power is back within 24 hours of proof of payment, and you pay twice the connection fee, which an order of 2009 sets at 9.044760 euros at low voltage, with no later update found. Until December 31, 2026, no electricity, gas or water supply of a vulnerable consumer, in practice a bono social recipient, may be cut at all (RD-ley 8/2021, article 4, extended by RD-ley 7/2026, article 4). That period stops the clock between the demand and the cut-off.

Home insurance: required for a mortgage, or by your lease

For tenants, no law read for this guide makes home insurance compulsory. The LAU leaves a lease’s terms to the parties within its housing rules (article 4), so a lease clause can require a policy. Buyers with a mortgage are another story. Under the mortgage market law, mortgaged property must be insured against damage for its appraised value (Ley 2/1981, article 8), covering at least insurance classes 8 and 9, fire and other property damage, theft excepted (RD 716/2009, article 10). Ley 5/2019 lets the lender require that policy, but not refuse an equivalent one from another insurer, at signing or at renewal, nor charge for reviewing it (article 17), as the mortgage guide explains.

Put the supplies in your name this week

The order of play: get a recent bill from the landlord or seller, copy the CUPS, call the electricity and gas retailers to change the holder, then contact the water utility and register on the padrón. While you’re still visiting homes, ask which companies supply each one, alongside the owner and rent checks in the rental search guide, and order internet with the phone and internet guide.

My verdict for a tenant taking over supplies that are still connected: you can handle all of this alone, by phone or online. I’d bring in your town’s or region’s consumer services when a canceled supply needs new paperwork, a retailer charges a penalty the decree doesn’t allow, or a bono social application is refused.
