The Equality and Human Rights Commission (EHRC) is carrying out the survey to make sure current laws are offering protection for both believers and atheists.
The research is part of a three year programme to create a better understanding of belief and faith by EHRC.
It will remain open until the middle of October and you can take part by clicking here.
Chief Executive of the Equality and Human Rights Commission Mark Hammond said: "Everyone has the right to be treated with fairness, dignity and respect, that includes respect for people's faith or beliefs, and respect for the rights of others.
"We are well aware of the complexity in dealing with such issues. Undertaking this major piece of work will help to build our understanding about how well the law is working so we can fully examine the adequacy of the current legal framework for religion or belief."
The Evangelical Alliance is encouraging its members to take part following recent high profile court cases brought against Christians.
It's raised concerns current equality legislation is unfairly biased against Christians
Director of the EA Steve Clifford said: "The Alliance and others who have raised concerns over a long period about people being marginalised because of their religion or beliefs.
"We welcome this great opportunity for Christians and those of other faiths to share their experiences of discrimination in areas such as employment or service provision.
"It is really important that we take this opportunity and we will be encouraging the 2 million evangelical Christians in Great Britain to respond."
Dr Don Horrocks of the Alliance said: "The Alliance has been highlighting to the Commission for some time the perceived imbalance in what is widely regarded as a discriminatory human rights hierarchy.
"This has not been helped by the Commission joining cases against those claiming discrimination on the grounds of religion and belief, rather than supporting them."
"There is a danger of a hierarchy of rights being established with religion and belief at the bottom.
"It is therefore encouraging, following meetings with the Commission, that a new attitude is emerging which wants to take religion and belief rights seriously."
