Electricity, Gas and Water in Spain: Setting Up Utilities as a Briton

Setting up utilities in Spain as a Briton means dealing with up to four separate suppliers: electricity, gas, water and the town hall’s waste fee. Each has a different price setter, so no single comparison tool covers them all. Electricity is where you have real choice. Water is local. Gas depends on whether you have a pipe or a bottle. The official pages do not ask a UK tenant for UK documents, and they do not treat Withdrawal Agreement holders differently from new arrivals. 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 should you check before you sign up for power and water?

Do these before you hand over an IBAN (the account number suppliers bill by direct debit).

Who the holder is. Electricity and water contracts sit in one name. If you rent, the Spanish rules favor you: a tenant who is the actual user with valid title and is up to date on payments puts the existing electricity contract in their own name with no further steps, and for a lease that is not treated as a termination followed by a new connection. The new contracts that result from a change of holder are free. Water is different: in Madrid the owner or the tenant can sign, the latter only if the lease says so.

What the lease already covers. Under the urban leasing law, services with individual meters (electricity, gas, water) are always the tenant’s to pay. General building costs pass to a tenant only by a written clause stating the annual amount. See our renting guide.

The CUPS. It is the supply point code printed on every electricity and gas bill. You need it to connect, switch company, change holder and apply for the bono social, according to the CNMC.

The contract and its exit. Read the summary document first. Before you sign, the retailer must send a separate summary showing the main terms, any early-termination penalty, the holder, the CUPS and the address. No guarantee deposit can be charged, and deposits paid earlier had to be refunded within four months.

Your padron. Some water companies price by the number of people in the home, and they want your town hall registration to prove it. See our empadronamiento guide for how that registration works.

Which documents the supplier accepts. Here the pages go quiet. The CNMC list asks for a DNI and does not say whether an NIE or passport will do; Seville’s water company names both. If you have no NIE yet, read our NIE guide first. The pages do not say whether a UK account can pay a Spanish direct debit; a Spanish account is the safe plan (see our bank account guide).

GOV.UK’s Living in Spain guide, last updated July 3, 2026, has no section on bills, and no UK agency step is needed to start a Spanish supply. The official pages do not say otherwise.

Who sets the price for each utility, and how do you start?

This is the table to keep. Rules as read on October 4, 2026.

Verdict: compare electricity hard.

How does electricity work, and which tariff should you pick?

You have two families of contract. The PVPC is the regulated one. The free market is everything else.

The regulated PVPC

The PVPC is open to households on low-voltage supply with contracted power of 10 kW or less. It has a power term, an access-toll energy term, an hourly energy-cost term and, where relevant, reactive energy. Since 2026 the energy cost mixes the daily market (weight 0.45) with a futures basket (0.55), after lower futures weights in 2024 and 2025.

Your energy price changes hour by hour. Red Eléctrica publishes next-day hourly prices at 20:15 for 2.0TD consumers, the domestic tariff. On the peninsula, the Balearics and the Canaries, weekdays are peak from 10:00 to 14:00 and 18:00 to 22:00 and off-peak from 00:00 to 8:00, with flat hours in between. Weekends and national holidays are off-peak all day.

The free market

A free-market retailer sets its own price. The CNMC comparator is meant for households and small businesses, and if you open it through the QR code or link on your bill, it loads your own consumption data automatically. Contracts are annual and renew automatically. You may move between the PVPC and the free market freely, with no extra charge if the technical conditions stay the same.

My pick: start on whatever the home already has, read two bills, then compare using the QR link.

Contracted power, meter and timing

You choose your contracted power. A pure reduction costs nothing beyond what the connection rules provide, and a valid change must take effect within 72 hours, or five working days when field work is needed on low voltage. The CNMC adds that an increase can cost money, depending on the connection rights attached to the supply point.

Legal time to connect a new supply is 5 to 7 working days. The customer may rent the meter or buy it. The only official rental values found date from 2008 and 2013, so the pages do not give a 2026 figure.

Switching and contract changes

Switching retailer must be completed within 10 working days of signing the new contract, extended by 5 working days when complex field work is needed. The retailer must give at least one month’s written notice, separate from the bill, of any change to contract terms, and you may then cancel at no cost. These rules sit in Real Decreto 88/2026, in force since February 12, 2026.

What about gas, butane and water?

Natural gas

The regulated gas tariff, the TUR, is open to individual consumers on supply pressure of 4 bar or less using under 50,000 kWh a year, and to residential owners’ communities. Real Decreto-ley 25/2026 limits the October 2026 rise in the raw-material cost to 35 percent over the cost in force since July 1, 2026, and the January 2027 rise to 15 percent.

One trap: leaving the TUR before January 1, 2027 means paying an accumulated average debt of 2.051412 cents per kWh billed since October 1, 2026 or since contracting, plus a financial cost and taxes, per the resolution.

Per the CNMC, switching gas supplier is free and must be done within 3 weeks, you need the CUPS to contract, and door-to-door sales are banned for gas.

Bottled butane

If your home has no gas pipe, you buy bottles. The maximum pre-tax price for 8 kg to under 20 kg bottles is 123.4447 cents per kg from September 15, 2026. MITECO lists the maximum retail price of the 12.5 kg bottle, with VAT and hydrocarbons tax, at 18.84 euros on the peninsula and the Balearics until November 16, 2026, up from 17.83 euros.

Water

No national water price exists. Three companies show how much it varies.

• Madrid (Canal de Isabel II): a fixed service fee plus a fee by consumption, billed every two months. The 2026 tariff sheet sets domestic blocks of up to 20, 20 to 40, 40 to 60 and above 60 cubic meters per two months, with winter and summer columns. For adduction (bulk supply) alone, the second block costs 0.6286 euros per cubic meter in winter or 0.7854 in summer, and the third 1.6199 or 2.4300; distribution, sewerage and treatment are charged on top.
• Seville (EMASESA): the 2026 ordinance prices block 1, up to 110 liters per inhabitant per day, at 0.641 euros per cubic meter for supply, 0.395 for sewage discharge and 0.412 for treatment, before VAT. The number of inhabitants must be accredited by the holder’s padron registration; otherwise the blocks apply per dwelling.
• Barcelona (AMB): a monthly fixed fee for supply only that depends on the dwelling type. For types C to H it runs from 10.58 euros for C to 59.10 euros for H.

Other municipalities were not read, so check your own water company’s page.

The waste fee

Ley 7/2022 required local authorities to set a specific, non-deficit waste fee within three years, so a tasa de basuras exists or will exist for every home. Madrid’s city fee page says tenants benefit but owners are billed as substitutes.

How much tax is on the bill, and what is the bono social?

VAT and the electricity tax

Two pages disagree. The AEAT rate table of June 2026 says the 10 percent VAT on electricity (10 kW or less) and natural gas applied only from March 22 to May 31, 2026, and that the rest of 2026 carries the general 21 percent. The AEAT news page, updated October 2, 2026, says Real Decreto-ley 25/2026 sets a conditional cut to 10 percent for November and December 2026.

Plan on 21 percent, the newer page governing only if its condition is met. The decree-law says the earlier cuts did not apply in September, so the permanent rates apply to October supplies. The electricity cut in November applies only if the September electricity price index is more than 15 percent above September a year earlier; gas has its own test on the gas index, and December repeats both on October. The electricity cut covers contracts of 10 kW or less and severely vulnerable bono social holders, whatever your nationality.

The special electricity tax has a permanent rate of 5.11269632 percent. The 2026 cut to 0.5 percent, conditional and limited to August and September, did not apply in September. Water, and waste and wastewater services, carry 10 percent VAT.

The bono social

The bono social is a discount on the PVPC. Only an individual holding the electricity contract of their main home, on the PVPC, can be a vulnerable consumer. One route is household income up to 1.5 times the 14-payment IPREM (a public income benchmark), with add-ons for extra adults and minors; large families and minimum pensioners also qualify. For a single person, MITECO gives 12,600 euros a year.

The permanent discount is 35 percent, or 50 percent for severely vulnerable consumers. For January 1 to December 31, 2026, Real Decreto-ley 7/2026 raises them to 42.5 and 57.5 percent. The MITECO requirements page agrees but also carries a stale line about December 31, 2025, so plan on the decree-law’s end date. The official pages do not say whether the higher discounts continue after December 31, 2026.

You apply to a reference retailer by office, phone, fax, email or post; the MITECO how-to page lists the routes. The retailer has 10 working days to answer a complete file.

Who do you complain to when a bill goes wrong?

Complain to the retailer or distributor first. The company must answer within 15 working days, and then you may use other routes, according to Real Decreto 88/2026: the consumer arbitration boards, an accredited alternative dispute body, or a regional complaints procedure where your region has set one up.

On arbitration, the consumer arbitration page says a maximum of six months, while the regulation says the award must come within 90 calendar days, extendable by up to 90 in complex cases. Plan on the regulation, and remember arbitration is voluntary. The customer service law covers water, gas and electricity suppliers, but companies have until December 28, 2026 to adapt.

Your first week: who can do this alone, and when to get help

You can do all of it alone. Week one: ask the landlord for the CUPS and the current holder, put the electricity contract in your name (free), then ask the water company what it needs. The next utility is your phone line: see our phone and internet guide.

Get help in two cases. If a retailer will not say which documents it accepts, ask in writing. If a complaint stalls past 15 working days, go to arbitration or your region’s complaints procedure, if it has one.
