If you are still unhappy with the response

If you are still unhappy after their review, or you have not received a written offer of resolution within 8 weeks of the date we received your complaint, you may be eligible to refer your case to the Financial Ombudsman Service (FOS). The FOS is an independent body that arbitrates on complaints.

The FOS can be contacted at:

Post: Financial Ombudsman Service, Exchange Tower, London E14 9SR

Telephone: 0800 0234567 or 0300 1239123



You have six months from the date of our final response to refer your complaint to the FOS. This does not affect your right to take legal action, however, the FOS will not adjudicate on any case where litigation has commenced.
