I've been using River Swale organics for a couple of months now. Produce is excellent and they offer email alerts and recipe ideas each week - helpful for those winter veg especially. They also offer a range of other goods to deliver at the same time.
With the box scheme, your order can be changed via email or phone to the local contact - a very useful more personal service.

Excellent produce in the box scheme - good quality and tasty. They offer delivery to the door but also supply a lot of the organic shops in the area.
Very friendly helpful staff and a wide range of produce available. Their website gives you all the info you need to start with the box scheme or order.
