Utility Warehouse – Have you any experience of this company?

I was approached by a rep from this company while doing my weekly shopping with a view to changing my gas and electric, phone, internet providers.
I understand they act as middlemen, but does anyone have any experience of how they operate? I have not yet made an appointment and would welcome your views.

They are a reputable company. They come out top in Which surveys for the best deals. They operate a multi-level sales system, all their reps are self employed. You will be okay with them. Check them out online. www.utilitywarehouse.co.uk
