Cost of Conference Interpretation in Belgium: Rates

Conference interpreting is one of the most technically demanding forms of language services, requiring highly specialised professionals and sophisticated equipment. For Belgian companies, associations, and institutions planning multilingual events, understanding the cost structure is essential for accurate budgeting.

Types of conference interpreting

The two main modes of conference interpreting have very different cost profiles:

• Simultaneous interpreting: interpreters work in soundproofed booths and translate in real time as the speaker is talking. Listeners follow via headsets tuned to their language channel. This mode requires a minimum of two interpreters per language per booth (they alternate every 20 to 30 minutes), plus professional booth and headset equipment. It is the standard for large multilingual conferences, EU-style meetings, and international events
• Consecutive interpreting: the speaker pauses regularly while the interpreter translates. No booth or headset equipment is needed. This mode is less expensive in equipment terms but doubles the effective speaking time, making it unsuitable for conferences with many speakers or tight time slots

Day rates for conference interpreters in Belgium

Conference interpreter day rates in Belgium reflect the high professional standards and specialised training required. As a general guide for the Belgian market:

• Simultaneous interpreter (common language pairs, EN/FR/NL/DE): €500 to €900 per interpreter per day
• Simultaneous interpreter (rare languages, specialised technical or legal topics): €700 to €1,200+ per interpreter per day
• Consecutive interpreter: €400 to €700 per interpreter per day, depending on language pair and complexity
• Half-day rates: most interpreters apply a rate of 60 to 70% of the full day rate for half-day assignments

Equipment costs

For simultaneous interpreting, technical equipment is a significant budget item:

• Interpreting booths (mobile, ISO 4043 compliant): €300 to €600 per booth per day, plus transport and installation
• Receiver units and headsets: €5 to €15 per unit per day (typically one per delegate)
• Technical operator: €200 to €400 per day for on-site technical support
• Total equipment cost for a 100-person, two-language event: typically €1,500 to €3,000 per day

Travel and accommodation costs

For events outside Brussels or in other Belgian cities, travel costs for interpreters are generally reimbursed at cost. For international events, flights, accommodation, and per diem allowances apply. TranslateBE coordinates the full logistics of interpreter travel so you can focus on your event.

The total budget for a one-day bilingual conference with simultaneous interpreting in Brussels (two interpreters, equipment for 80 delegates, technical operator) typically ranges from €3,000 to €5,500 depending on the language pair and equipment rental chosen.
