The following information must be submitted:

1.Timesheet – has to be printed out & signed by the interpreter and the client’s legal representative, solicitor, social worker, medical expert etc. thus confirming the interpreting starting and finishing time and submitted as a scanned document or clear photo via e-mail.

5.If traveled by public transport - all travel expenses (bus, train, metro) must be supported by scanned copies or good quality pictures of actual paper tickets or screenshots/online statements (for example, Oyster) in case of card/online payment with visible costs. Bank statements cannot be accepted as proof of travel expenses. Any expenses not supported by proofs can not be claimed by us from our client and therefore reimbursed to the interpreter as well.

6.Car park expenses (CP) - we authorize car park expenses up to £10 and it must be supported with the scan or picture of ticket or screenshot of payment if paid by mobile phone. If CP expenses are expected to be higher – it has to be agreed with NTIS UK / UKLST prior to assignment. In some cases, we might be able to advise another CP near the venue at more reasonable costs. Toll expenses are not acceptable without prior written permission from Booking Team.

7.We DO NOT authorize expenses for taxi services. However, there can be some exceptions related to the accessibility of the venue by other means – that needs to be agreed upon with NTIS UK / UKSLT prior to the appointment.
