Some of our churches share in Local Ecumenical Partnerships. The Bishops of England & Wales have published helpful leaflets about them, and how Catholics can share in their life:

A Local Ecumenical Partnership (LEP) is ‘where there is a formal written agreement affecting the ministry, congregational life, buildings, and/or mission projects of more than one denomination; and a recognition of that agreement by the Sponsoring Body and the appropriate denominational authorities’. (For Catholics this is the Bishop).

The leaflets are downloadable from here on the Bishops' Conference website (foot of the page).

The titles are:

Prologue - Why LEPs
LEP Leaflet 1 - Singles
LEP Leaflet 2 - Covenants
LEP Leaflet 3 - Shared Buildings
LEP Leaflet 4 - Chaplaincy
LEP Leaflet 5 - Mission Partnerships
LEP Leaflet 6 - Education
