Take to any household waste recycling centre. These should be placed in the hardcore container.
Only 90kg (190lbs) per day (about what you can fit in a standard hatchback car boot. Equivalent to about 33 bricks).
You will be charged to dispose of ceramic tiles at your local HWRC, find out more about the charges.
For larger quantities you may need to consider hiring a skip or a company to remove the material.
Tiles being disposed of by a business are business waste.
