I'm sorry I don't know more about the Church but this is what I could find.
The brick building of polygonal design with a low lantern above, and stands in the middle of Broadfield community centre, built between 1980 and 1981 as an integral part of the new Broadfield neighbourhood's community centre, is a combined church and community centre shared by the Broadfield Christian Fellowship (an Evangelical congregation), Anglicans and Roman Catholics. The Anglican community is included in the parish of Southgate under St Mary's Church. Sunday mass is 9:30am. The church is commonly referred to as CTL.
For more information on the church please visit the church's website. Here.

Happy Caching.
If any body would like to expand to this series please do, I would just ask that you could let Sadexploration know first so he can keep track of the Church numbers and names to avoid duplication.
