Our aim is to solve any complaint to your complete satisfaction. Once you have made a complaint, an advisor will contact you by phone or email. We will try and resolve the complaint then and there – but we may need to get more information, in which case we will try and resolve the complaint within 10 days. If we can’t resolve it, we will agree with you what we can do. If you contact us by post, we will reply to you within 10days.

If an advisor can’t sort out your complaint, we’ll escalate it. A Manager will then work with you to try and sort out the problem. We settle most complaints by this stage but, if not, we’ll explain our final position. In some cases, we might send you a ‘deadlock’ letter. This means there is nothing more we can do.

You can ask for a Manager to review your complaint at any time if our Adviser hasn’t been able to help, and hasn’t already offered to refer things to a Manager.

If you are still unhappy with the outcome of your complaint, after a period of 8 weeks, or after you have received a ‘deadlock’ letter from us, you may ask for help from the Ombudsman Services, a free, independent disputes arbitration service approved by OFCOM who will examine your complaint and make an unbiased judgement regarding it.

You can contact the Ombudsman Services in the following ways:
