MuslimsInBritain.org collates the data accumulated from the directory of masjids to produce a report every two years, of the numbers of masjids and prayer rooms in the UK, their affiliations, modes of worship, women's facilities, their managements' cultural and linguistic associations, distribution by capacity, etc. The same data is also analysed against local authority and by Westminster parliamentary constituency, to provide local and electoral perspectives on the Muslim community.

"Islam and Muslims In Britain: A Guide for Non-Muslims" was originally commissioned and published by the City of London Police in 2004 as part of a drive to improve community relations in that part of London through educating police officers. It was subsequently adopted by many other UK police forces and other public organisations, even as broad as the pan-Europe OSCE.

"By far the best thing of its kind which I have seen produced by a public sector body." Rev. Flora Winfield, Assistant Secretary General of Religions for Peace

MuslimsInBritain.org's directory of UK masjids confronts the problematic issues of factional sects and cultural and ethnic exclusivity directly, by displaying each masjid's predominant sectarian 'theme', which at its most generous can be taken as that masjid's customery form of Islamic worship, but in most cases is also a debilitatingly exclusive determinant of who is allowed to perform or speak of anything beyond the basic salaah. The site also shows the cultural and ethnic reference point of each masjid's management committee.

It is vital to understand that there is not a single Masjid in the UK that does not welcome anyone, Muslim of whatever belief, or non-Muslim, attending for devotional purposes within reasonable bounds - the contrary would be considered outrageous. Even so, outrage is curtailed when one third of the UK's masjids - all South-Asian-managed - make no provision for women. Otherwise, the only entity one might consider that explicitly excludes Muslims from entering any of its premises is the tiny but vociferous Ahmadiyya religion that claims a questionable association with Islam.

While masjid managements' sectarianism and ethnic exclusivity are the two biggest obstacles that prevent masjids from addressing extremism effectively, there are many other aspects of masjid governance that show widespread and systematic failure to address the Muslim community's need for positive engagement between the masjids and both their local Muslim community and the non-Muslim neighbourhood in which they live.

The MuslimsInBritain.org Governance pages detail all the numerous things that every masjid must undertake before it can claim to be a responsible participant in the wider community. Failure to do so only demonstrates a failure of the UK's numerous masjids to recognise what outsiders regularly observe, that Muslims in Britain may be in the community but they are rarely of the community. These are the primary points of Governance and Engagement that must be addressed:

1. Accountability of the management and trustees to the congregants and community;
2. Accessibility of the facilities, to women, to the physically limited and sensorily impaired, to other language users than the dominant group;
3. Inclusivity with full, safe and open access regardless of sect, ethnicity, gender or ability;
4. Madrassas, teaching and supplementary services, e.g. shari'ah advice, to competent, professional standards and protection of the vulnerable;
5. Converts and returnees to Islam provided with comprehensive, independent and objective support in a culturally appropriate context;
6. Countering extremism provided by fully informed, competent, objective and realistic sources fully engaged with the responsible authorities;
7. Local engagement with the neighbourhood and local agencies on a responsible, sensitive and inclusive level with mutual representation;
8. Human investment in the masjid's resources, developing imams and staff to provide genuine pastoral services to the whole community.
