The popular service is a celebration which brings together professional membership organisations.

ICE has announced that it will once again partner with the Royal Institution of Chartered Surveyors (RICS) for an annual carol service to take place in St Margaret's Church, Westminster Abbey.
The service had been on a hiatus due to lockdown restrictions in 2020 but prior to that has always been an occasion for the staff and members of ICE and those of many other institutions to join in a pre-Christmas celebration.
All ICE members and staff are invited to come along and bring family and friends to help round off the institution’s year. As in previous years, invitations will be sent to other institutions and organisations in the London area with the aim of making it a multi-disciplinary gathering.
