What MCC 1731 covers
Merchant Category Code 1731 is the ISO 18245 identifier used by the card networks for electrical contractors. Acquirers, issuers and regulators use this code to set interchange, scheme fees, fraud rules and reporting categories for every transaction your business processes.
Electrical wiring, installation and maintenance services. Choosing the right MCC is critical: an incorrect code can lead to higher interchange, surcharges, or, in regulated categories, declined transactions and account holds.
MCC 1731 identifies electrical contractors, covering services from electrical wiring and installation to maintenance and repair for residential, commercial, and industrial clients. Merchants in this category vary from independent electricians to larger electrical engineering firms.
Ticket sizes range from small amounts for minor repairs or safety inspections to substantial sums for full property rewiring or industrial-scale electrical installations. Transaction frequency is typically moderate, often driven by project timelines or emergency call-outs.
Chargebacks are generally low but can arise from disputes over work quality, perceived incomplete projects, or discrepancies with quoted prices. Fraud risk is low due to the service-oriented, in-person nature of the business.
Clear contracts, detailed quotes, and robust communication are vital. There are no specific scheme programmes for electrical contractors that impact typical payment processing directly.
Cardflo’s comprehensive payment gateway supports various payment types, including in-person card acceptance via terminals and online invoicing, catering to both immediate service payments and larger project billing. Our dispute resolution support helps electrical contractors maintain a good standing with acquirers by efficiently addressing any chargebacks.
Electrical contractors should optimise their payment acceptance for efficiency and dispute prevention. For smaller call-out jobs, employing mobile card terminals for on-site payments helps secure funds at the point of service and reduces card-not-present risk.
For larger projects like rewiring or new installations, secure deposits via online payment links with 3DS2, ensuring liability shift. Always provide detailed quotes and contracts outlining the scope of work, materials, and payment milestones.
Maintain clear signage on your website and at your premises regarding your payment, cancellation, and returns policies. A multi-acquirer strategy can provide greater resilience and potentially better pricing for varying transaction volumes.
Acquirer and acquirer assessment stance.
Low-risk standard board. Generally stable and predictable, with low overall fraud.
Standard underwriting is applied with no exceptional reserve requirements.
Dispute and chargeback profile.
The most prevalent chargeback reason codes are 13.1 / 4853 (services not as described or received) and 13.4 / 4855 (goods or services returned or cancelled), often linked to perceived incomplete work or discrepancies in project scope.
To defend 13.1, provide signed job sheets, detailed invoices matching the agreed quote, and photographic evidence of completed electrical work.
For 13.4, demonstrate customer acceptance through sign-offs on completion forms, and ensure your service agreement clearly outlines terms for cancellations or material returns, proving the service was rendered as contracted.

Common questions
What forms of payment are most common and secure for electrical contractors taking deposits for large projects?
For large project deposits, commercial card payments with 3D Secure are advisable for online transactions, providing liability shift. However, bank transfers or open banking payments offer greater security against chargebacks due to their irrevocability.
Cardflo supports all these options, allowing contractors to choose the most appropriate and secure method for each scenario, while also offering competitive pricing for higher-value card transactions.
How can electrical contractors protect themselves from chargebacks related to 'defective merchandise' if they supply parts?
If electrical contractors supply parts, they should ensure clear documentation of the parts used, including serial numbers and manufacturers' warranties. Customer sign-off on the installation and confirmation that the system is fully functional at completion are crucial.
For any alleged 'defective merchandise', the primary recourse is often through the manufacturer's warranty, which should be clearly communicated to the customer, supported by a system for handling returns or warranty claims effectively.
Are there specific industry regulations that impact payment processing for electrical contractors?
While no specific payment scheme regulations directly impact electrical contractors, general consumer protection laws, particularly regarding cancellation rights, warranties, and transparency of pricing, are highly relevant.
Merchants must ensure their invoice terms, cancellation policies, and proof of work comply with local consumer regulations to minimise disputes, alongside standard PCI DSS compliance for handling card data.
What contractual elements are essential for an electrical contractor to include to protect against payment disputes on commercial projects?
For commercial electrical projects, a robust contract is pivotal. It must meticulously detail the full scope of work, including specific electrical diagrams, material specifications, and regulatory compliance (e. g. , IET Wiring Regulations).
Clearly define project milestones with corresponding payment schedules, distinguishing between deposit, progress, and final payments. Include clauses for change orders, requiring written and signed authorisation for any deviations from the original scope.
Specify warranties for labour and materials, alongside a clear dispute resolution procedure. Crucially, explicitly state that payment is due upon completion of agreed milestones, with provisions for late payment penalties.
This clarity minimises ambiguity that could lead to payment disagreements.
How should an electrician handle a customer's claim that a repair was ineffective after initial payment, to prevent a chargeback?
When an electrician receives a claim that a repair was ineffective after initial payment, the immediate priority is transparent communication and resolution to prevent a chargeback. Promptly engage with the customer to understand the specific issue.
Offer a follow-up visit to reinspect the work and rectify any legitimate issues under warranty or as a goodwill gesture. Document all communication, including dates of contact, details of the complaint, and steps taken for resolution.
If a follow-up visit occurs, obtain a new signed job sheet confirming the re-evaluation and any further work. If a refund or partial refund is agreed, process it promptly and provide proof, as this pre-empts a chargeback.
Clear, proactive problem-solving greatly reduces dispute potential.
