How do I add shipping over a certain cart amount to be free?

I want shipping over £50 to be automatically listed as free but I'm not sure how to do that. All help would be appreciated!

Not sure I understand your question. I see on your site you already have the free shipping over £50 mentioned on the announcement bar. That should make it obvious to your customers they get free shipping if they order over £50 worth of your products. Or did you mean you want something like "Free shipping over £50" visible on every product? (If so, I think this would be overkill.)

Or maybe you mean you want orders £50 to reflect free shipping on checkout? If so, you need to create an automatic discount. Go to Discount then on Trigger, pick Automatic Discount. On Promotion, pick Free Shipping. Under Applies To, pick Orders Over and specify £49.99. Fill out the rest and then save your discount.

BTW, I got a notice that your store isn't set up to process payment. Make sure you connect to Paypal and/or Stripe after you test your store.
