What is a Sign Language Interpreter invoice?

A sign language interpreter invoice is issued by a qualified British Sign Language (BSL) interpreter to a client for professional interpreting services. BSL interpreters facilitate communication between hearing and Deaf individuals in a wide range of settings: legal hearings, medical appointments, educational environments, corporate meetings, conferences, and public events. BSL interpreters in the UK are typically registered with the National Registers of Communication Professionals working with Deaf and Deafblind People (NRCPD) or the Association of Sign Language Interpreters (ASLI). Registration demonstrates qualification to at least Level 6 in BSL and Interpreting, and compliance with a professional code of practice. The Equality Act 2010 requires public bodies and employers to make reasonable adjustments to ensure Deaf employees and service users can access communication. This drives significant demand for BSL interpreters in legal, healthcare, and educational settings.

How to invoice as a sign language interpreter

Issue invoices on completion of the assignment. Include the exact start and finish times, the location, and the nature of the assignment (legal hearing, medical appointment, conference) on the invoice. Minimum booking fees are standard in the interpreting profession. A minimum of 2 hours is common to cover the interpreter's preparation and commitment to blocking out their schedule. State this clearly in your booking terms. For legal proceedings, courts, and tribunal bookings, rate premiums apply given the high-stakes nature of the work. Many legal interpreters charge a separate preparation rate for reviewing materials in advance. For government-funded assignments (NHS, education, legal aid), invoicing may go through a central agency or interpreting service contract rather than directly to the client. Confirm the invoicing route at booking.

Frequently asked questions

What is the typical BSL interpreter hourly rate in the UK?
BSL interpreter rates in the UK typically range from £60 to £90 per hour in 2026 for registered interpreters. Legal and specialist interpreting commands premium rates. Most interpreters charge a minimum booking fee of 2 hours (£120 to £180 minimum) to account for preparation and travel commitment.
What qualifications do BSL interpreters need?
NRCPD registration requires as a minimum a Level 6 qualification in BSL and interpreting (typically RSLI or equivalent). Full NRCPD registration as a Registered Sign Language Interpreter (RSLI) is the professional standard. Trainee interpreters may register at a lower level while completing qualifications.
Who is responsible for booking a BSL interpreter?
Under the Equality Act 2010, employers and public bodies have a duty to make reasonable adjustments for Deaf employees and service users. This includes arranging and funding BSL interpreting. The Deaf person should not have to fund their own interpreting in an employment or public service context.
Do BSL interpreters charge VAT?
VAT registration is required when annual taxable turnover exceeds £90,000. Interpreters with full diaries of paid work may reach this threshold. Standard rate 20% applies to all interpreting fees. Many public sector clients (NHS, councils) can reclaim the VAT.
What is the cancellation policy for BSL interpreting bookings?
Most BSL interpreters charge a cancellation fee for late cancellations (within 24-48 hours) and 100% of the minimum booking fee for no-shows. This is because the interpreter has committed that time and may have declined other bookings. State your cancellation policy clearly when accepting a booking.
