A power pole beside a Spanish plot does not establish that your future home can connect to it on the terms you expect. You need a defined supply requirement, the local distributor’s connection conditions and a separate understanding of the installation on your property.
Before committing to the land, find out whether “electricity available” means an active supply, an old connection, temporary construction power or merely nearby infrastructure. Those descriptions can lead to very different works, costs and completion dates.
Identify the network company before choosing a tariff
The distribuidora operates the distribution network in the area. The comercializadora sells the electricity under your supply contract. You can choose a retailer, but selecting one does not resolve the physical connection to a new plot.
For example, e-distribución publishes a connection process covering application, technical review, an offer and execution. Its process is relevant where it is the distributor; other areas have their own network company.
Ask the seller for existing supply documents and have the point’s status confirmed. An old bill is useful evidence of an earlier supply, not proof that the present power requirement can be met without alterations. Where a property has been split, confirm that the advertised supply actually belongs to the parcel you are buying.
Describe the intended demand accurately
The requested power is expressed in kilowatts, or kW. Energy consumed over time is measured in kWh. A low historic electricity bill does not establish the connection capacity needed for a larger new house with electric heating and vehicle charging.
Have the designer or qualified installer prepare the demand assumptions. Include the intended heating and cooling system, cooking, pool equipment, charging and any planned additional dwelling. Technical design considers how the installation will operate; simply adding appliance labels is not a substitute.
Supply an accurate location plan and the intended delivery point. Keep the application consistent with the planning proposal. If you request power for one small building and later change the scheme substantially, the earlier response may no longer answer the relevant question.
Understand the dividing line between network and private work
Article 25 of Royal Decree 1048/2013 sets out rules concerning network extensions and who bears their cost. One category concerns supplies up to 100 kW at low voltage on qualifying urbanised land already equipped with the required services. The power threshold alone is not enough to establish eligibility.
Ask the distributor to identify the basis of its offer, the required works, payment items and the applicant’s responsibilities. A plot described as urban in an advertisement may still have infrastructure obligations. Check that point within the planning review.
| Cost group | What to establish in writing |
|---|---|
| Network works | Connection point, scope, ownership and delivery responsibility |
| Civil works | Excavation, road crossings, reinstatement and permissions |
| Private installation | The equipment and route included within your property |
| Applicable charges | What each payment covers and how it is calculated |
| Completion information | Certificates and conditions required before contracting supply |
Do not assume a charge for connection rights includes every trench or private cable. Equally, avoid paying two contractors for the same civil works. A drawing showing who delivers each section is often clearer than several quotations using different terminology.
A hypothetical budget shows why scope matters
Suppose an illustrative project contains €2,400 of specified connection works, €1,500 of separate trench and reinstatement works, and €3,100 for the private installation. These invented amounts total €7,000 before taxes and any additional charges. They are a budgeting exercise, not regulated fees, current quotations or a national price range.
If a second contractor offers €4,000 for “all electrics”, ask which of those groups is included. It might cover only the house interior, leaving both the connection and the route across the plot outside its scope. Alternatively, its trench allowance may overlap an item already in the main building contract.
Replace each placeholder with a dated offer based on the same plans. State whether permit charges, testing, documentation and temporary supply are included. Carry genuinely unresolved items as visible allowances with an owner and a next action, rather than hiding them inside an unexplained contingency.
Put the connection on the construction programme
The physical installation may be only one stage. Road permissions, routes across other land, network work and completion documentation can all affect when power becomes usable. Ask for a programme that separates these dependencies from the duration of the site works.
Coordinate the electrical route with the water connection and other services. Technical separation and operator requirements still apply; the opportunity to coordinate excavation is not permission to put everything into an arbitrary shared trench.
Where substantial excavation is needed, reconcile the scope with the earthworks quotation. This avoids both omissions and double counting. Identify who repairs the final surface, particularly if a driveway or pavement will already have been completed.
Construction power is a separate planning question. Ask what temporary supply the contractor needs, when it must be available and how the temporary arrangement relates to the eventual household supply. Include any adaptation or removal work in the relevant package.
Verify that the completed point can actually be contracted
The CUPS is the identification code for the supply point. Before treating the connection as finished, confirm its contractable status and that the required installation documentation is complete. Keep the accepted conditions, payment records and certificates with the property file.
Add the confirmed connection costs and dates to the full plot preparation budget. During the pre-purchase checks, distinguish a verbal indication from written conditions that apply to your intended demand and remain valid for the proposed timetable.
Send the plot location, intended building use and existing supply information. A clear plan and professionally assessed demand make it possible to ask focused questions about the necessary works and who pays for each part.
