Tip around 10–12.5% for standard table service in England. On a 50 GBP bill that is 5.00 GBP, for a total of 55.00 GBP.
No service charge on the bill, so around 10% applies.
In practice: Most sit-down restaurants add a discretionary service charge of 10–12.5%, in which case you owe nothing more — check the bill before adding anything. Pubs: buy at the bar and don't tip, unless you're ordering at a table.
