Applying for a certificate

Applying for a certificate

All certificates are £10 each. For those being posted out, there is a fee of £1.60 to cover the cost of it being sent by registered post.

If the event occurred within the Royal Borough of Kensington and Chelsea and you would like to obtain a certified copy of a certificate from this office then you have three options:

Our opening hours for applications in person are between 8am and 4pm from Monday to Friday. With a standard application, certificates will be available for collection or posting within seven working days. If you have an urgent application, we have a same day service whereby certificates may be collected within one hour of ordering upon payment of an additional fee of £15.00.

If your application is made from within the UK then you should enclose a letter/application form containing all the relevant details, a postal order made payable to ‘R.B.K.& C.’ and a stamped addressed envelope. Please do not send cash by post. If you are applying by post from outside the UK then you may only pay by international money order, in pounds sterling, made payable to ‘R.B.K.& C.’ Please note: we are no longer able to accept cheques.

We are only able to supply a copy of a birth, death, marriage or civil partnership certificate if the event occurred within the Royal Borough of Kensington and Chelsea on or after the 1 July 1837. Please remember that the Registration Service has been in operation since 1837 and over the years the boundaries of the Royal Borough have changed.

What may have been part of the district of Chelsea in 1849, may now be located in the Hammersmith and Fulham or Westminster districts and vice-versa.

When any boundary changes occurred, the relevant registers were transferred to the new district. It may be worth noting that although our staff will try their hardest to locate the entry, all of our searches have to be done manually and we cannot always guarantee to find the record you are looking for.

If the event occurred elsewhere in England or Wales then you will either need to apply directly to the Register Office for that area or to the General Register Office.

To help us process your application as quickly as possible:

Give us as much information as possible

The more information you give us about the register entry of which you need a copy, the easier it will be for us to find the entry. Please note that General Register Office references are different to those held locally.

We regret that we cannot undertake searches of an indefinite or protracted nature. Usually a search in the index, covering a period not exceeding five years, will be made but only where accurate details of the particular registration have been given. If a wider search is required it may be necessary for you to undertake a General Search at the Kensington and Chelsea Register Office.

Send separate postal orders for multiple certificate requests

If you are making applications for multiple certificates (for example, one birth and two marriage certificates) then it will speed the administration if you can include a separate postal order for each and every application. If we are unable to find an entry we will return your unused postal orders to you.

Always include a stamped addressed envelope for return

This guarantees the correct address and postcode are on the envelope.

The Same Day Service takes priority

Please bear in mind that family research will not take priority over more urgent applications such as birth certificates for passport applications, marriage certificates for legal purposes, etc. unless you are using our same day service. A standard ancestral research application can sometimes take as long as three weeks to process.
