On this page you can download the forms that we use when we look into complaints. The forms are for you to give us your details and explain more about what’s happened with your complaint. Once you have completed the forms you can return them to us by post to Financial Ombudsman Service, Exchange Tower, London E14 6SR.

Or if you'd prefer you can complete and submit this information online, or call us on 0800 023 4567 and we can take the details over the phone.

For financial services complaints:

For all complaints we'll need a signed copy of our complaint form. Depending on what your complaint is about, we may also need an additional questionnaire.

There is a high demand for our service at the moment. If you’ve sent us details of your complaint, you can expect to receive an acknowledgement from us within 2 weeks – although this can be up to 2 months for a PPI complaint.

At busy times, it can take around 4 months for us to allocate your case to a case handler for assessment – although this might be longer for some product types. You can find out more about timelines for specific complaint types in the complaints we can help with section of this website. We’ll be in touch as soon as your complaint is allocated. In the meantime, if you’re facing financial hardship or severe ill health, please let us know.
