This service will cease on 31 December 2018

We offer a checking service for British citizenship application forms. This reduces the risk of mistakes which could delay your application.

This service also allows you to keep your passport and original documents, so you can travel while your application is being considered by the Home Office.

Our staff are licensed by the Office of the Immigration Services Commissioner (OISC).

How it works

  1. We check your application form to ensure it is correctly completed.
  2. We photocopy your passport and other documents, and certify them.
  3. We return your passport and original documents to you.
  4. We send the application by special delivery and give you a tracking reference number so you can track your application through Royal Mail.

Joint Citizenship and Passport Service (JCAP)

The Joint Citizenship and Passport Service is no longer available in conjunction with the Nationality Checking Service. However, if you complete the online version of the application you may use the Nationality Document Return Service (NDRS) and still used the JCAP service. Unlike NCS we do not check any of your supporting documents. The NDRS is available at Merton Register Office as a walk in service from 9.00am to 3.00pm Monday to Friday except the 3rd Thursday of the month.


Monday to Friday between 9.00am - 4.00pm and some Saturdays which will be announced as and when capacity allows.
