Most experienced interpreters work freelance, either self-booked or through interpreting agencies, setting day and hourly rates that typically run from GBP 200 to GBP 400+ for a half or full day depending on subject matter, location and notice period.
For a freelance interpreter with GBP 48,000 in annual profit after insurance, registration and CPD costs:
Booking utilisation -- the proportion of available working days actually billed -- is the key driver of freelance income. Interpreters with an established client base and mixed agency/direct bookings typically achieve higher utilisation than those newly qualified, and legal or medical specialism bookings often pay a premium that improves overall day-rate economics.
