Utility Fraud Criminal Lawyers

Utility Fraud: Illegal Connections and Supply Fraud

The fraud of electricity supply and other essential utilities (gas, water, telecommunications) is regulated in Arts. 255 and 256 of the Spanish Criminal Code. It protects the supplier's assets and, more broadly, the integrity of the regulated essential-services market. Consolidated case-law has defined the contours of the offence: fraud exists when consumption is obtained without passing through the legitimate measurement and billing system. As criminal defence lawyers specialising in utility fraud, we intervene from the first complaint by the distribution company, frequently linked to proceedings for indoor cannabis cultivation (Art. 368 CP) or for illegal occupation of properties.

The typical modalities are exhaustively listed. Art. 255 CP punishes fraud by direct connection to the electricity, gas or water grid bypassing the meter; the malicious alteration of measuring devices; or any other mechanism aimed at obtaining the supply without payment. Art. 256 CP specifically sanctions the non-consensual use of third-party telecommunications terminals. A growing variant is the manipulation of smart meters via software or bypass connections falsifying remote readings, as well as derivations exploiting community rooms or public-service lines. A particular situation is that of squatters using pre-existing connections that they did not install.

The penalties are graduated according to amount and modality. If the defrauded value exceeds EUR 400, Art. 255 CP imposes a 3 to 12 months' fine; if below, the fine is 1 to 3 months; either way it is a minor offence (Art. 13.4 CP). The €400 threshold also applies to meter tampering under Art. 255.1.2 CP; only Art. 255.3 (Organic Law 1/2026) disregards the amount: where the fraud is used to power premises for drug cultivation or trafficking, the penalty is 6 to 18 months' prison or a fine of 12 to 24 months. Art. 256 CP provides equivalent fines for unlawful terminal use. To this sanction the civil liability for the defrauded amount plus interest is always added, together with the registration of criminal record with its collateral consequences. In indoor cannabis cultivation cases, the fraud usually concurs with the public-health offence of Art. 368 CP, opening a much more severe criminal scenario.

The technical defence articulates several complementary lines. First, the ignorance of the illegal connection (mistake of fact, Art. 14 CP): when the property was occupied or rented with installations tampered by previous third parties, without the current user being aware, intent is absent. Second, the challenge to the inspection report: distribution companies usually produce reports with calculations based on estimated consumption and theoretical curves; our independent technical expertise recalculates the consumption really attributable to the period, often reducing it below the EUR 400 threshold. Third, the discussion of the defrauded value and possible application of non-applicable tariffs or brackets. Fourth, the separation of offences in cases of concurrence with drug trafficking: we contest the attribution of knowledge of the connection to the cultivator to avoid double charge. Fifth, the statute of limitations and formal defects in the chain of custody of the seized meters.

In current forensic practice we observe a strong increase in proceedings linked to indoor cannabis cultivation, especially since the massive deployment of smart meters allowing distributors to detect anomalous consumption in real time. EU Directives 2019/944 and 2024/1711 on the internal electricity market and consolidated case-law on digital chain of custody have hardened evidentiary requirements in this area. Organic Law 1/2025 on the efficiency of the Public Justice Service is a procedural and organisational statute: it does not amend the Criminal Code or its penalties. At Alonso Sala, we tackle each file with electrical and computer forensic experts who reconstruct the real consumption chronology, identify inconsistencies in the distributor's reports and build defensive strategies adapted to the client profile (tenant, owner, cultivator, mere user). We treat utility fraud as a high-precision technical-expert procedure, not as a simple accounting file.

Limitation and Regularisation

As to limitation, the forms in Arts. 255.1, 255.2 and 256 CP are minor offences (Art. 13.4 CP) and are time-barred after one year; only fraud under Art. 255.3 CP, to supply premises used for drug cultivation or trafficking, is a less serious offence, time-barred after five years. Such a short period may exclude criminal liability in old fraud cases, leaving only the civil claim. The regularisation of the supply —lawful contracting and payment of the defrauded amount before trial— operates as a damage-repair mitigating factor (Art. 21.5 CP) and favours a plea agreement with minimum penalty. The civil liability for the defrauded amount subsists in any case, regardless of the criminal outcome, and is usually quantified through contrasted consumption expertise.

Crime Types

• Direct connection: Direct connection to the electrical grid bypassing the meter.
• Meter tampering: Altering the measurement mechanism to record consumption lower than actual.
• Unauthorized use: Continuing to consume a utility after the contract has ended, where this is done by one of the means in Art. 255 CP (installed devices, meter tampering or other clandestine means).

Defence Lines

Defence in these cases is usually built around the absence of intent (unawareness of the illegal connection), incorrect fraud quantification by the utility company, or statute of limitations. In cannabis cultivation cases, it is crucial to separate both charges to avoid penalty accumulation.
