Hi all, Firstly a big huge thankyou for all of you who helped us as we were in panic mode, mmm, I mean applying for the extension to my wife's visa (at the halfway stage on the five year route). I have been a member here for a number of years and I could not have got this far without the help freely given on here, well done to those who give their time and effort. I wanted to share our experience in the hope that it helps other's on the same path as us. Firstly, allow plenty of time. We found the online form very confusing and we had two aborted attempts before we were confident enough to submit our application. Checking your answers is possible but the software is not easy to use (and I'm an electronics engineer!). We made a note of documents that we had to upload as we went through the online form so nothing was missed. We started gathering all the documents well in advance but we still had to find more - especially the proof of address ones. We scanned all our documents into PDF's which kept the file size down, there is a limit of 6mB per file. In case your files are too big, this may be useful: https://smallpdf.com/pdf-converter Here is a list of documents we submitted: Birth Certificates for my wife, myself and our daughter My deed poll (I changed my name many years ago) Council tax bills, from memory these are required but we also used these for proof of address. We rent our home, so we made sure that both our names are on the tenancy agreements and these were uploaded The family consent and family declaration forms, both downlaoded, printed, signed Spouse declaration Marriage certificate All passports old and new (myself, my asawa and our daughter) My wifes' BRP IELTs A2 Certificate 6 payslips stamped as originals, letter from employer, contract of employment 6 Bank statements For proof of address we used: My wifes' NI application and letter showing her NI number Letters from her bank Letter from the letting agent Water bills Electricity/gas bills We did not include any photos or a letter from ourselves. I was confused at the timings but here is my understanding. You can submit your application up to 28 days before the current BRP expires. The IELT's is valid for 2 years so we did that a few months before the deadline (I suggest not taking to far in advance though in case the rules change) My wife had to attend a Sopra Steria centre for her biometrics. At first I thought this had to be before the BRP expired but when we submitted the application (on 1st August) we were told to make the appointment before 3rd November so don't panic and pay for an appointment at short notice. The decision was made five weeks after the appointment for my wifes' biometrics and the new BRP is valid for 30 months from that date. All that remains now is to renew my wifes' passport and change over to our married name at last, the BRP will have to be changed too. I wish all of you the best of luck.
