What happens to the paper before it leaves the UK
A civil record such as a birth or marriage certificate can start life as a fresh certified copy from Stoke-on-Trent Register Office, Civic Centre, Glebe Street, so the original document itself never has to travel anywhere or leave your hands.
A signed paper that is not a civil record, such as a degree certificate or a company letter, moves forward exactly as it was issued, with no local stop or extra check needed before the next stage of the journey begins.
The paper then goes by post to the Legalisation Office (Foreign, Commonwealth & Development Office) at PO Box 6255, Milton Keynes MK10 1XX. An apostille issued in Stoke-on-Trent for use in Singapore follows this same single route, whichever UK town the paper set off from.
That office checks the signature, adds the stamp, and posts the complete bundle straight back rather than forwarding it on anywhere else, so the paper stays under your control until you choose to send it on to Singapore yourself in your own time.
Singapore's Hague membership, and why it is enough
Singapore joined the Hague Convention in 2021, making it one of the more recent additions among the destinations a Stoke-on-Trent applicant is likely to deal with, and that membership is what makes a single UK stamp the end of the process.
An apostille is the correct and sufficient certification for documents used in Singapore; no embassy visit, consular chain or second stamp from a Singaporean office sits behind the one already issued back in the United Kingdom by ordinary post, start to finish.
Document legalisation for Singapore therefore stops the moment the Legalisation Office has done its part, which surprises applicants used to a country that still runs a longer chain of separate offices for the very same kind of family paper each time.
The 2021 date is background rather than a step to plan around; what an applicant actually needs is simply a genuine, signed original or a fresh certified copy, sent once to the one office that issues the stamp itself by post.
The fee and the wait
The official fee is £45 per document by standard post, or £40 per document through the next working day service, an option kept for registered businesses rather than a private individual applying on their own for one certificate at a time.
Standard post runs up to 25 working days, and that figure sits on top of the postage time itself on both legs of the trip. Anyone arranging an apostille from United Kingdom to Singapore against a fixed date should post the paper well ahead of that window closing.
Each document is billed on its own, so three certificates sent together cost three separate fees rather than one combined charge for the parcel, which is worth checking carefully before the envelope is sealed and finally sent off in the post.
There is no separate charge for the return post itself beyond the fee already quoted, though a sender who wants tracked or signed-for delivery both ways should budget the ordinary postage cost for that choice on top of the stated figure.
Common reasons people need this for Singapore
People send documents down this route for a Singapore work pass application, a company set up there, a degree needed for a job offer, or a marriage that has to be recorded there on arrival in the country itself, among many other reasons an applicant might have.
Whatever you need for an apostille for Singapore, the underlying process does not change with the reason: one signed paper, one UK office, one stamp, and nothing further expected once the paper is handed over there in Singapore by the person carrying it.
Keep a copy of anything posted before it leaves your hands, since a scan costs nothing and saves a second trip to Stoke-on-Trent Register Office if a question ever comes up about the paper later on, weeks or months after it was sent.
None of these reasons changes which office handles the stamp or what it actually costs; the destination decides only whether the one UK stamp is the end of the whole story, and for Singapore, since 2021, it plainly and simply is.
