The new offer, which has been available in the US for some time, offers a 70/30 split, which is five percent more than the existing deal.
Using Amazon's Digital Text Platform (DTP), Brits can upload their books to the Kindle Store for purchase by owners of Amazon's eBook reader.
However, there a number of requirements placed upon anyone wishing to take up the new royalty offer. These include an on-sale price that's between £1.49 and £6.99 and 20 percent below the list price of the physical book. It must also be made available for sale in all locations which the author or publisher has rights for.
"The 70 percent royalty option for Kindle Digital Text Platform has been available for a few months for sales to US customers," said Greg Greeley, Amazon Vice President, European Retail.
"We are excited to be able to announce the launch of the 70 percent royalty option in the UK. Now authors and publishers worldwide can offer more content to Kindle customers in the UK and make more money from the books they sell."
Amazon said the new option is in addition to and not replacing the existing royalty deal.
