The Challenge

Brian Corstjens is a Dutch-born electrician who has been living and working on the Costa Blanca for over 15 years. As an REBT-certified installer registered with Iberdrola and the Comunitat Valenciana, he handles high-quality electrical work — from emergency call-outs in the middle of the night to full solar panel and EV charging installations.

The Costa Blanca is home to over 50,000 Dutch residents, plus hundreds of thousands of tourists annually. Yet Brian was finding clients almost exclusively through word of mouth. A Google search for 'electrician Benidorm' or 'electricista Benidorm' returned no results for him. His expertise and certifications were completely invisible online.

The challenge was twofold: build a website that (1) ranks high in Google for Dutch speakers, Spanish locals, and English speakers simultaneously, and (2) immediately establishes trust — because when someone calls their electrician, they need to know straight away they're dealing with a certified professional.

The Solution

Trilingual Website (NL / ES / EN)

The website is fully available in Dutch, Spanish, and English. Each language has its own URL structure and optimized content, making Brian findable to expats, local Spaniards, and international Costa Blanca residents all at once.

Trust Through Certifications and Registrations

REBT certification, Iberdrola registration, and the authority to issue official boletines eléctricos are prominently displayed. For a service where people literally trust you with their home, trust is the single most important conversion factor.

24/7 Availability and Direct WhatsApp Integration

An electrical emergency doesn't wait. The site always shows 24/7 phone availability and a direct WhatsApp button, lowering the barrier to contact as much as possible — so potential clients don't go searching elsewhere.

Full Service Overview for 12 Services

From solar panels to air conditioning, from switchboard replacement to EV charging installation — all 12 services are clearly described in dedicated sections. This boosts Google visibility and helps clients understand what's possible.

The website is built on HakmanDev's proven Next.js architecture, optimized for multilingual SEO and fast mobile loading.

Why this works for an electrician in Benidorm

The Costa Blanca is a region where tens of thousands of Dutch residents know Spain well but speak less Spanish. They prefer to search for service providers in Dutch or English — and they want to know immediately that the person they hire is certified and trustworthy. A website that speaks their language, radiates trust, and makes direct contact easy is worth its weight in gold in this market segment.

Want to be found on Google as a tradesperson too?
