Replacing a home's consumer unit: cost and scope in Spain
Distinguish a consumer-unit replacement from a complete rewire and compare quotes with clearly defined protection, testing and taxes.
Planning reference per domestic consumer-unit replacement: EUR300-600 including VAT in Madrid; EUR300-600 excluding VAT in Badalona, equivalent to EUR363-726 if 21% applies. The combined EUR300-726 interval is not an Alicante average or a ceiling for every installation. Confirm the applicable VAT rate and scope with the installer.

What is usually included in a quote
Each professional may structure quotes differently, but most project budgets follow this logic.

Factors affecting the price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Number and characteristics of circuits
Conductor condition and enclosure space
Specified protection and planned loads
Access, planned outage and defect repair
Next step
Describe your project and request an electrician's quote: provide the location, issue, property use and survey availability. Attach only safely taken photographs of the closed board. Request written supply, labour, testing, tax, exclusion and extra-work terms before commissioning. If the cause is unknown, begin with an electrical installation inspection and agree what diagnosis is included. Choose by scope and documentation, not just the initial figure.
Replacing a home's consumer unit: cost and scope in Spain
Distinguish a consumer-unit replacement from a complete rewire and compare quotes with clearly defined protection, testing and taxes.
Replacing a consumer unit can be a defined intervention when its enclosure or protective devices need renewing and the existing circuits remain usable. It does not, by itself, turn an old electrical installation into a fully renewed one. Before a contract is agreed, an installer should establish what each circuit supplies, the condition of connections and the factors governing protective-device selection. A photograph of the closed front helps prepare the visit but cannot replace measurements or certify safety remotely.
Diagnosis, scope and handover
Distinguish a consumer-unit replacement from a complete rewire and compare quotes with clearly defined protection, testing and taxes.
Request a consumer-unit replacement quote identifying the enclosure, proposed protective devices and work on existing cables. Separate new circuits, defect repairs and additional documentation. If the intention is to add electric cooking, a heat pump or an EV charger, describe those loads at the outset. Extra space in a board does not prove that the supply, wiring or available capacity can support every extension.
Planning reference per domestic consumer-unit replacement: EUR300-600 including VAT in Madrid; EUR300-600 excluding VAT in Badalona, equivalent to EUR363-726 if 21% applies. The combined EUR300-726 interval is not an Alicante average or a ceiling for every installation. Confirm the applicable VAT rate and scope with the installer.
Do not select a quote by counting switches in a photograph. Ask for a circuit and component schedule showing manufacturer, reference and purpose. Residual-current, overcurrent and overvoltage protection are not interchangeable terms. The professional should justify the arrangement for the actual loads and conditions rather than treating a brand or marketing label as a substitute for that assessment.
In an occupied home, agree when power will be interrupted and which equipment needs special planning. Flag essential equipment, alarms, cameras or electronic access. Do not assume an improvised arrangement will keep them operational. The installer should explain the work sequence, tests before returning the installation to service and what happens if a discovered fault prevents same-day completion. Duration is confirmed during the survey; a one-hour replacement is not guaranteed.
Compare the final tax-inclusive total. Two quotes with the same headline figure may include different taxes and components. Keep the net amount, applied VAT and exclusions in separate columns. This guide normalises one VAT-exclusive reference using a 21% assumption but does not determine your contract's tax treatment. Nor does it add every possible extra to the board price: only items justified by the assessment and approved scope belong in the final budget.

Read articleFrequently asked questions
Does replacement include all the wiring?
No. This guide covers the domestic consumer unit. Wiring, new circuits and repairs should appear as separate items where required.
Does the range include VAT?
It combines a VAT-inclusive tariff with one normalised using a 21% assumption. Confirm the applicable tax and total in your quote; this is not a fixed Alicante quotation.
Is a new electrical certificate needed?
That depends on the scope and procedure. Ask the installer to confirm the necessary documents and whether preparation is included rather than assuming every board change has the same requirement.
Will the whole home lose power?
Plan an interruption with the installer and flag essential equipment. Duration depends on the installation and any defects discovered; agree a contingency plan.
