What the translation covers
An official translation of a Government-Issued ID Copy in Reading reproduces everything printed on the copy: the full name, the date and place of birth, the document number, the issuing state, the dates of issue and expiry, and any wording along the machine-readable strip. Marks that carry no text, such as a hologram, are described rather than guessed at.
Who signs it, and why that matters
The translator is an ITI or CIOL qualified certified translator, and the signature turns a good rendering into a document a body can act on. A certified translation of a Government-Issued ID Copy in the United Kingdom carries a certificate of accuracy naming both languages, the qualification and the date. That is the certification UKVI and the General Register Office work with.
Cost and turnaround
Pricing is about £25 for each page of the source, and an ID copy is normally a single sheet, so most orders are simple to price. Standard turnaround is 2-3 business days and express work lands within 24 hours. The certificate is identical either way; the express lane changes only where the job sits in the queue.
Where an ID translation gets used
An ID copy rarely travels alone. It usually sits inside a larger file: a visa or residence application, a bank or company account opening, a property matter, an enrolment. Sending the ID with the other records as one job keeps the spelling of your name identical across every sheet, and one certificate can then cover the whole bundle.
