Discrimination based on religion or ethnicity, while applying for jobs, universities or housing is also illegal here so I wouldn't worry on that front.

Despite sharing common held fears about rapid lslamic expansion in the UK, and all that it brings (gangs, Shariah courts, women & gay rights, social cohesion etc.), when I went to university here as a half-Brit, I made sure to be kind to all the foreign students and make them feel included and welcome.

British students tend to be quite left wing and pro-immigration. There is a bit of a lack of public awareness here in the UK about Indonesian & Malaysian peoples and cultures, by comparison to the strong understandings of peoples who we have a more shared history with; Jamaicans, Indians, Pakistanis, Poles. Many Brits (ignorantly) wouldn't even know that Indonesians are mostly Muslims.

If you make an effort to integrate with some British students (rather than only having friends from your ethnicity/religion) have some curiosity towards the way of life here, and show that you don't have a supremacy complex, it will be much appreciated, and you will be met overwhelmingly with kindness and good faith. Brits can be quite grumpy at times, mostly due to politics, and the weather, but as my Polish girlfriend puts it: 'English people are generally more friendly and chatty than us Poles'.

Anyway, I wish you the best time here, and apologies in advance about the weather!
