How we handle your complaint

Once we've received your complaint, we aim to resolve it as quickly as possible. We will write to you within five working days to acknowledge your complaint, and we aim to resolve all complaints within 20 working days. If this isn't possible, we'll let you know and tell you when you can expect a response.

Referral to the Financial Ombudsman Service

Some complaints may be eligible for referral to the Financial Ombudsman Service, a free disputes resolution service. Your complaint may be eligible if MDUSL provides introduction and administration of your annual subscription as a credit agreement provided by Premium Credit Ltd.

Complaints related to MDU indemnity and/or other benefits provided at the discretion of the board of management of the MDU will not be eligible. If you're uncertain whether your complaint is eligible for referral to the Financial Ombudsman Service, please contact

If your complaint is eligible and you're not satisfied with our final response, or you haven't received a final response within eight weeks, you can contact the Financial Ombudsman Service:

Financial Ombudsman Service
Exchange Tower
London E14 9SR

Referral to the Legal Ombudsman

If your complaint relates to the services provided by our in-house legal department and you haven't received a final response to a complaint within eight weeks, or we've been unable to settle your complaint using our internal complaints process, you have the right to complain to the Legal Ombudsman, an independent complaints body that deals with legal services complaints.

The Legal Ombudsman expects complaints to be made to them within one year of the date of the act or omission that you're concerned about, or within one year of you realising there was a concern.

You have six months from receiving our final response to the complaint to complain to the Legal Ombudsman:

Legal Ombudsman
PO Box 6806
Wolverhampton WV1 9WJ
