Catholic groups in London and Hertfordshire

We’ve put together lots of the Catholic groups and organisations that you can get involved with in the Diocese of Westminster – from volunteer work to joining a community. You can use our filter tool below if you’re looking for something in particular.


If you’re looking to join a group that meets up regularly, like once a week, then check out What’s On. This includes Parish Youth Groups.


Guild of St Stephen

The Guild of St Stephen is an international organisation of Altar Servers founded in England in 1904. It encourages, positively and practically, the highest standards of serving at the Church’s liturgy and so contribute to the whole community’s participation in a more fruitful worship of God.


London Catholic Young Adults

The purpose of this group is to help young Catholics get to know other young Catholics in London. Being a Catholic is great but sometimes can be difficult – it’s important to have people you can share your faith with as well as deal with the struggles and encourage you too.


Mount Street Jesuit Centre

We aim to provide a programme of events for young adults (men and women aged 18-35) as they continue to develop on their faith journey. With Masses, socials, pilgrimages, or faith formation opportunities we like to encourage young adults in what can be a very busy world to come together in a community, take time to reflect through attending retreats, or one day sessions or ongoing courses that feed the soul.


RMI London Hostel

The RMI sisters offer you a place to stay in London. Like all our other houses all over the world, we aim to provide a welcoming, safe and harmonious place to live while you face the challenges of city life in your studies and work. The hostel is based on Christian ideals and values. Young women between the ages of 18 and 25, of any creed or nationality, who are obliged to live away from home for reasons of work or study are all welcome!



Shalom is a Catholic community, founded in Brazil, and is present in more than 15 countries, with over 5,000 missionary members. In London, Shalom started among a group of young people who shared the same desire to spread the community’s spirituality. Through prayer, Eucharistic celebration, spiritual formation, teachings, retreats, social gatherings and evangelisation, the London branch is beginning to grow under the guidance of Shalom’s missionaries in Rome.


Sion Community

Our spiritual ethos could be described as Charismatic and Eucharistic. We pray the Prayer of the Church, worship in a charismatic style and have regular times of quiet adoration of the Blessed Sacrament. We encourage the personal spiritual development of all our members in ways appropriate to their state and journey in life. We endeavour to remain faithful to the call God has given us as a Community.



SPEC is a Catholic community and the Youth Retreat Centre of the Diocese of Westminster. Every year, a group of young adults are welcomed into the SPEC community to spend a year in formation and evangelisation. These young adults form the volunteer missionary team. SPEC’s community seeks to live an authentically Catholic life, joined in God’s mission to reach the youth of the Diocese with the Gospel of Jesus Christ.


University Chaplaincy Centre

Newman House is the Catholic Chaplaincy Centre for students in central London and a small residential community with 63 student places. Come and stay in the heart of London, walking distance from Theatreland, the British Museum, and at the edge of the West End. Only 10 minutes from both Euston and King’s Cross St Pancras, Newman House is the perfect base for a short break, or for a place to continue your studies whilst the University Quarter is nice and quiet.
