The British paid their slavery reparations. They did a bond issue in 1837 and raised the funds to compensating former slave owners for the loss of their property after abolition.
Under the terms of the Act, the British government raised £20 million to pay out for the loss of the slaves as business assets to the former owners of the freed slaves. The reparations bond was finally paid off in 2015.

The British gave reparations to the slave owners. The slave owners in the US were paid nothing--the 14th amendment specifically forbade any payment to anyone for the loss of a slave.

It was easier for the British since the slaves weren't in England but in remote colonies.
