The Financial Ombudsman Service
If you are not happy with our final response, or eight weeks have passed since you complained, you may be able to refer your complaint to the Financial Ombudsman Service. It is free. You need to do so within six months of our final response.
The Ombudsman can consider complaints from individuals, and from businesses that meet its size limits, for example a micro-enterprise or small business. It will tell you whether it can help.
