Connecting Electricity and Internet in Barcelona: Documents and Timelines

What you need to set up electricity and internet in Barcelona

Start with the home, not with choosing a company. For any connection, the flat needs a cédula de habitabilidad, the administrative document stating that the home is fit to live in. The Generalitat says plainly that without it you cannot set up water, electricity, gas or telecoms [1][2]. If you are renting, ask the landlord for a copy before signing the lease: in Catalonia a home cannot be offered for rent without a cédula [1].

The Ajuntament de Barcelona lists the documents you will need for the application: NIE or passport, bank details for direct debit, the number and start date of the lease, the last utility bill and the cédula de habitabilidad [3]. If the landlord or an agent handled the lease, they often take care of this. If the service is already connected, it is enough to change the account holder or the bank details; if not, it takes time and there may be extra charges [3].

This article deliberately names no companies or tariffs: they change, and the choice depends on your address and consumption. You can compare electricity and gas offers on the official CNMC website [4].

Electricity: how the connection works

In Spain electricity involves two parties. The distribuidora owns the network and the connection point; the comercializadora sells you the energy. Getting connected involves two steps: a network access contract and a supply contract. You can sign the access contract with the distribuidora directly or through the comercializadora you choose, which will do it on your behalf [4].

The connection point is identified by the CUPS code. It appears on an old bill and on the distribuidora’s website. Which of three cases applies depends on the flat: you take over an existing contract, sign a new contract for an existing point, or connect a new point (new build). According to the CNMC guide: if you sign a contract in place of the previous tenant and do not change the contracted power, you pay nothing for access, extension or work on the meter; if you lower the power, you pay only for work on the meter; if you raise it, you pay all three items.

For a new point you pay for connection, inspection and work on the meter [4]. These charges are regulated by the state and are the same across the country, and the distribuidora may ask for a security deposit [4]. For the application you need the CUPS, the contracted power, the address, the contract holder’s details and payment details, and in some cases a Certificado de Instalación or Boletín eléctrico [4].

According to the CNMC guide, an electricity contract is either on the regulated tariff (PVPC) with a comercializadora de referencia or on the free market. Under PVPC the electricity price varies. Separately, comercializadoras de referencia offer a price fixed for 12 months [4]. A one-year PVPC contract does not mean the price is fixed for a year. The guide dates from January 2022, so check current timescales and charges on the CNMC page. Read the termination terms before you sign: some offers carry penalties for early termination [4].

Gas and water

In Barcelona most buildings are connected to mains gas for hot water and heating; some buildings in the old town use gas bottles [3]. Gas, like electricity, is sold on the free market. You will need the same documents about the home and the account holder.

Water: in Catalonia water supply is the responsibility of the municipalities, and in Barcelona the service is provided by a single operator [3][5]. To connect, you will be asked for an identity document, the full address, the lease or purchase contract and the cédula de habitabilidad [5]. The company will install a meter (bought or rented) and connect you to the network.

The company is responsible for the pipe from the street to the entrance of the building; inside the home, you are [5]. Prices are approved by the Comissió de Preus de Catalunya and published in the DOGC [5]. The adhesion contract (contrato de adhesión) must be available to you in Catalan [5]. Sources differ on how often you are billed (the Ajuntament page says quarterly, the Generalitat page says every two months), so check with the operator.

Internet, phone and mobile

The market is open, there are many operators, and fibre is available almost everywhere in the city [3]. The Ajuntament estimates that a line is installed within five days, sometimes longer while the formalities are completed [3]. Consumer rights here are broader than in most household contracts, and they are worth knowing.

• Before you sign, the operator must give you a short contract summary: price, term, termination conditions, internet speed (article 67.2 of Ley 11/2022) [6].
• A consumer contract cannot last longer than 24 months (article 67.7). After automatic renewal you can terminate it at any time, and the operator cannot require more than one month’s notice [6].
• The operator may change the terms only for reasons expressly stated in the contract and must give you one month’s notice. If you do not agree, you can terminate the contract without a penalty (article 67.8) [6][7].
• If the contract was concluded by phone, online or at your home, you have 14 days to withdraw [7].
• Porting a number takes one working day; when you port a mobile number you do not need to cancel the old contract, as the new operator submits the request [7].
• Prepaid SIM cards are registered against an identity document: this is a legal requirement [3].
• If you have a complaint, go first to the operator’s customer service and ask for a reference number. If there is no answer within 30 days or you are not satisfied with it, the complaint goes to the consumer service for your municipality, and for telecoms issues you can contact the Oficina de Atención al Usuario de Telecomunicaciones [7].

Equipment: penalties for a router that is not returned do happen. The consumer protection agency advises checking how the contract describes returning equipment, and complaining if this information is missing [7].

Who pays for what if you rent

Under article 20 of the LAU, services measured by individual meters (water, electricity, gas) are always paid by the tenant. The building’s general expenses can be passed on to the tenant only if this is agreed in writing and the annual amount at the date of the contract is stated. The costs of the agent and of drawing up the contract remain with the landlord [8].

Put the contracts in your own name. This is not bureaucracy for its own sake: electricity, water or gas bills in the tenant’s name, paid for the last three months, are accepted as proof when registering on the padrón. The Ajuntament does not accept mobile and internet contracts for this purpose [9]. More on registration: empadronamiento in Barcelona. When you move in, photograph the meter readings and keep the photos. On renting in general: what to check in a lease.

Timelines: what to expect

There are no official “turnkey” timescales for the whole set of services in Catalonia. The Ajuntament page notes that connection may take about a week, with extra charges, if the supply was not connected before, and a phone line up to five days [3]. According to the CNMC guide, switching electricity supplier used to take up to three weeks; check current timescales on the CNMC page [4]. Allow plenty of time: submit the applications straight after signing the lease, not on moving day.

Common mistakes

• Not asking the landlord for the cédula de habitabilidad before signing the lease, and then being unable to connect the services [1][2].
• Leaving the contract in the name of the previous occupant or the landlord, so the bills cannot be used for the padrón [9].
• Accepting a “special offer” without reading the term, the early termination penalty and the conditions for returning equipment [6][7].
• Agreeing to a call or a visit from a “representative” and signing a contract on the doorstep without knowing there are 14 days to withdraw [7].
• Not taking meter readings when moving in.
• Signing a 24-month contract without checking the price after the promotional period.
