Capitalization is important in FE, as is spelling and punctuation.

Your GalleryType needs to be 'None'.

ShippingType needs to be 'Flat'.

Your shipping option is not one found on pages 135 through 136, of the advanced instructions.

Location should be City, Country.

Leave out the currency symbol in the StartPrice. eBay knows from the Action header, which currency you are using.

ProductName may give you an error. That field is used to add 'Products' to the Selling Manager Pro Inventory. This is being phased out in deference to SellerHub. I would delete this column.

You are including no CustomItemSpecifics. Brand and MPN may be required for this category, or not.

C:Brand

C:MPN

I am unsure whether the UK is using the eBay Product Catalog. Probably not, but in case...

I would add the following columns name (with values)

Product:EAN <- or UPC, both will work

Product:Brand

Product:MPN
