How soon will we deal with your complaint?

We will contact you initially within five working days of receiving your complaint. We will either respond with a full reply or send you an acknowledgement letter, which will tell you:

Once we have sent you an acknowledgement letter we will investigate your complaint fully and write to you with our findings. If your complaint is particularly complex, we may need to spend longer investigating it. In these cases, we will keep you up to date on our progress. In all cases we will respond to your complaint within 8 weeks, in line with the deadline set by the Financial Conduct Authority.

If you are unhappy with the way we are handling your complaint

All our complaint handlers are trained and monitored on their complaint handling skills. If at any time, you are unhappy with the way we are handling your complaint, you can ask to have it reviewed at a higher level.

The Financial Ombudsman Service

We try to resolve all complaints internally. However, if you remain unhappy with our response to your complaint, or if we have not resolved it 8 weeks after you first told us about it, you have the right to refer your complaint to the Financial Ombudsman Service. If you want the Financial Ombudsman Service to look into your complaint, you must refer it to them within 6 months of the date of our final response to you. You can contact them at:

If you bought one of our products online, you can also refer your complaint to the European Online Dispute Resolution platform. This service will pass on your details to the most appropriate dispute resolution service for the product you've bought. For insurance products this is likely to be the Financial Ombudsman Service.
