Call Chelsea Building Society using their UK number on 0345 166 9300. This will put you through to the helpline for existing mortgage customers, where you will be put in contact will a mortgage advisor. There is also a 24 hour automated line for simple account management, such as making mortgage payments, checking your balance or changing your password. However, for more specific information regarding your particular account, I recommend using the above number. The helpful representatives are more than willing to offer support on matters such as establishing mortgage repayment programs and discussing both the interest rates and security of doing so. Furthermore, information pertaining to your individual program and its policies is easier to ascertain in conversation than online.

The Chelsea Building Society mortgage helpline is open from 8am – 8pm, Monday to Friday, and from 9am -1pm on Saturdays. The line is closed on Sundays. Chelsea uses the regional calling code of ‘03’ and therefore charges the same standard rate of calling 01 and 02 numbers. Calls are just as cheap on a mobile as a landline service, though further network charges may apply.
