    The challenge

    Why poor English in customer interactions costs more than you think

    IWG Institute's Customer Service English program is a practical communication training designed for customer-facing professionals working in international or multilingual environments. The program focuses on the real communication situations customer service teams face — handling enquiries and complaints, managing difficult callers, writing professional responses, and building long-term customer relationships. Training is available as B2B group programs, 1:1 coaching, online, onsite or in a hybrid mode.

    Most customer service professionals in Finland have enough English to get by — they can answer a basic question, send a simple reply. The challenge is what happens when the interaction gets harder: an impatient international client on the phone, a written complaint that needs a careful response, a situation where the wrong word or tone damages the relationship.

    Generic language training doesn't address this. It teaches English as a subject. IWG Institute's Customer Service English treats language as a customer experience tool — built around the situations your team encounters every day, in your industry, with your customers.

    • Handling enquiries from international customers clearly and professionally
    • Managing complaints without escalating — in English, under pressure
    • Writing emails and chat responses that are warm, precise, and on-brand
    • Navigating telephone and video calls where tone and clarity are critical
    • Building rapport with customers from different cultural backgrounds
    • Representing the company professionally in every written and spoken interaction
    Program structure

    What the program covers

    MODULE 1
    Customer Communication Essentials
    Build the language for handling everyday customer interactions — enquiries, requests, and information-sharing — with clarity, warmth, and professionalism.
    MODULE 2
    Complaints & Difficult Interactions
    Learn to de-escalate, empathise, and resolve — with the exact language phrases needed to handle complaints professionally without damaging the relationship.
    MODULE 3
    Telephone & Video Communication
    Master tone, pacing, and clarity on calls. Practice the real scripts customer service professionals use — opening, closing, transferring, and handling difficult callers.
    MODULE 4
    Written Customer Communication
    Write emails, chat responses, and follow-up messages that are professional, empathetic, and on-brand — in a way that builds customer trust and reduces escalation.

    Training is based on real customer interaction scenarios drawn from your industry. Each programme is customised to the participant's role, team, and specific communication challenges.
