While unlawful discrimination can be hard to prove, you could theoretically be prosecuted if you refuse to rent to someone specifically due to their:

• Age
• Race
• Sex
• Gender identity
• Sexual orientation
• Marital status
• Disability
• Religion
• Pregnancy or their being on maternity leave

A key point to understand is that you are free to refuse to rent to anyone for any reason, as long as it is not with respect to one of these characteristics. For example, you can still refuse to rent to someone on the grounds that they are claiming housing benefit.
