Other than people occasionally saying a backhanded comment or copying racist jokes from family guy or such, there isn't so much 'denial of service' or any such mass systemic mistreatment of people in general in the UK.
What we do however still have is rampant name discrimination, which has been proven time and time again by people with non western names suddenly being offered up to 3x as many interviews just by changing their first name to something like John or Allan on their job applications (something which I myself am going to have to do as well as making up 2 years worth of I.T experience because no employer thinks using a PC at home daily and building them myself etc counts as sufficient I.T experience to type data into a computer).
There are talks within the rumour mill of making it as such that job applications should be made anonymous by law, but this still seems far from ever being implemented.
